DAYS 1-5 (JANUARY 26-30)

A swath of dry air ate up some of the early portion of yesterday’s precipitation event, cutting out a fair amount of what was already expected to be a fairly light snowfall. A healthy swath of moderate to heavy rain moved through the region overnight, along with milder temperatures, eating away at the already feeble snow pack in most of the region and keeping the ground bare where there isn’t any snow on the ground right now. Any more snow chances upcoming? Yes, eventually, but not anything significant in the immediate future – as in the next several days. Today, we’re mild initially as we say goodbye to the rain, exiting the eastern coastal areas early this morning. The balance of the day is dry, with lots of clouds, some sun, maybe a few pop up showers, a mild start, and a cooler finish on a gusty westerly breeze. Colder air arrives tonight and it will be modestly chilly on Friday as high pressure noses into the region. We may see more sun Friday than we have many days this month, one of, if not the, cloudiest month on record to date (will re-acquire updated sunshine data soon). No changes for the weekend outlook and heading into early next week. Expecting a cold front to swing through on Saturday with no more than a passing rain or snow shower, then the front comes back as a warm front Sunday ahead of a weaker area of low pressure to pass by to our north, bringing the front back through once again as a cold front early on Monday. The passages of that frontal pair brings more clouds than anything, but some light precipitation, favoring rain, may occur Sunday night and early Monday, based on current expected timing. A follow up wave of low pressure should remain to the south as it passes by later Monday.

TODAY: Cloudy start with rain showers in eastern coastal areas ending. Clouds break for sun at times thereafter but still the chance of a few pop-up showers of rain or mixed precipitation. Highs 40-47 except 48-55 South Coast / Cape Cod, occurring this morning, before slowly falling afternoon. Wind variable 5-15 MPH becoming SW to W 10-20 MPH with higher gusts.

TONIGHT: Clearing. Lows 17-24. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Mostly sunny. Highs 32-39. Wind NW 5-15 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.

SATURDAY: Partly sunny. Chance of a passing snow/mix/rain shower. through midday. Highs 37-44. Wind SW 10-20 MPH, shifting to NW, higher gusts possible.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH early becoming variable, then S up to 10 MPH.

SUNDAY: Increasing clouds. Highs 38-45. Wind S up to 10 MPH.

SUNDAY NIGHT: Cloudy with a chance of light rain/mix south and east, light mix/snow north and west. Lows 31-38. Wind SW 5-15 MPH.

MONDAY: Limited sun. Highs 35-42. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 31 – FEBRUARY 4)

While the overall pattern trends colder and has 1 or 2 opportunities for precipitation, favoring mix/frozen, the timing is a little up in the air. Windows of opportunity exist later January 31 to early February 1, February 2 into February 3, and again at the end of the period. Will bring things into better focus with time.

DAYS 11-15 (FEBRUARY 5-9)

Overall pattern looks a little colder with another storm threat at mid period.

DAYS 1-5 (JANUARY 25-29)

The upcoming storm system behaves as previously noted in terms of timing, coming in this afternoon and exiting early Thursday, with low pressure moving into the eastern Great Lakes and redeveloping right over southern New England before moving quickly seaward. Recent short range guidance trends have been consistently for a slightly weaker thrust of precipitation and slightly milder overall set-up, and after briefly considering erring on the side of “over-performance” before this trend got underway, I’m actually going to take the top edge off my initial snowfall estimate, which will appear in updated form in the detailed forecast below. Expect a little batch of very light to light snow to extend out from the approaching system that can put some flakes in the air but not likely have any real road impact sometime early this afternoon, favoring areas north of I-90 and west of I-95. The main batch of precipitation then arrives late in the day, before darkness falls for the western areas and at dusk or shortly after dark for eastern areas. For most it starts as snow, except the immediate coast and certainly the South Coast which have a much better shot at starting as a mix of snow and rain or even just rain. Before long, a definitive rain/snow line, perhaps with a narrow ribbon of sleet along with it, will not only be apparent but will waste little time moving northward across the WHW forecast area during the evening hours, followed by a solid moderate to heavy swath of rainfall during the late evening and overnight hours. The system is moving along swiftly enough that I expect this area of rain to exit from west to east before dawn on Thursday, leaving us with a drier day, mild in temperature, with an increasing breeze to help dry of most cleared surfaces. With colder air returning Thursday night we will have to watch for areas of melt-water and puddles freezing up – typical wintertime stuff – so be aware of that later that night and early Friday. Friday’s weather itself looks fair with a little less wind as a small ridge of high pressure, centered to the south but extending northward, moves across the region. The wind picks up again on Saturday as that high slides offshore and a low pressure area moves quickly west to east across southeastern Canada. This low will drag a cold front across the region which may produce a few showers of snow, mixed precipitation, and maybe even rain to the south, during the morning and midday hours, based on current expected timing. But that frontal boundary doesn’t get that far south and east of us and lifts right back across the region on Sunday while another low pressure disturbance moves through the eastern Great Lakes, destined for a path north of our region late Sunday through early Monday. This will bring some light precipitation later Sunday or Sunday night, in the form of snow or mix to the northwest, mix or rain to the southeast, to be fine-tuned as we get closer to its occurrence.

TODAY: Clouding up. Brief light snow possible north central to northeastern MA and southern NH midday or early afternoon. Snow/mix/rain arriving west to east late in the day, snow most likely inland, rain more likely coast. Highs 33-40. Wind NE 5-15 MPH.

TONIGHT: Overcast. Snow/mix/rain transitioning to rain during the evening south to north, rain possibly heavy at times late evening into overnight, ending west to east pre-dawn. Snow accumulation before change-over from little or nothing in coastal areas to a coating to 2 inches away from the coast, with 2-4 inches possible in higher elevations of central MA and southwestern NH. Temperatures slightly rising to 35-42 southern NH and central MA, 43-50 most areas except over 50 South Coast and Cape Cod. Wind E-SE 10-20 MPH, higher gusts, shifting to SW along the South Coast with an area of variable winds right along the track of the new low center.

THURSDAY: Clouds occasionally break for sun. Highs 40-47 except 48-55 South Coast / Cape Cod. Wind variable 5-15 MPH becoming W 10-20 MPH with higher gusts expected.

THURSDAY NIGHT: Clearing. Lows 17-24. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Sun/cloud mix. Highs 32-39. Wind NW 5-15 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.

SATURDAY: Partly sunny. Chance of a passing snow/mix/rain shower through midday. Highs 35-42. Wind SW 10-20 MPH, shifting to NW, with higher gusts possible.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH early becoming variable, then S up to 10 MPH.

SUNDAY: Increasing clouds. Chance of light rain/mix southeast and mix/snow northwest evening or night. Highs 38-45. Wind S up to 10 MPH.

DAYS 6-10 (JANUARY 30 – FEBRUARY 3)

Relatively weak disturbance (the one coming in late Sunday) exits early Monday January 30 with fair weather following through January 31. Continuing to watch the first few days of February for colder weather and a potential winter precipitation threat.

DAYS 11-15 (FEBRUARY 4-8)

Overall pattern looks a little colder with another storm threat around mid period.

DAYS 1-5 (JANUARY 24-28)

A quick review of yesterday’s storm-ending snow burst. For the most part the forecast amounts worked well, with a tendency for higher ends of ranges to be realized. There was a surprise regional jackpot area in eastern Middlesex and portions of Essex Counties, where up to a few inches over the forecast amounts occurred. One example is right here at WHW’s home in Woburn, where I was in a forecast 1-3 inch band, and received 5.5 inches. When shoveling the snow, I found it to be very much lighter weight than I had expected, while still being sticky (but not sopping wet). This indicates to me an atmosphere that was colder where the flakes form, but relatively mild (still cold enough for snow) at lower levels. And now that system is gone, and we get a little break today in a northwesterly air flow behind it. But don’t look now, here comes the next storm system! Still on track to be a snow to rain producer later Wednesday into early Thursday. Forecast snow amounts will appear below. The storm’s track takes it into the Great Lakes with a redevelopment right over our region, allowing warm air in aloft to easily change from frozen to liquid precipitation. The surface temperature profile during the storm’s passage will have a wide range, rising only to the middle to upper 30s in the northwestern portions of the WHW forecast area while the Cape Cod region soars to 50+, being southeast of the secondary low’s track. When this system departs Thursday, again we’ll get into a drying westerly air flow, setting us up for a full day of fair weather Friday as high pressure controls the weather. Saturday will feature mostly fair weather as well, but a cold front moving into the region may touch off a few snow showers which, if they occur, would be quick and passing, but also an indication that colder air is arriving – something we haven’t seen a whole lot of, by January standards anyway, during this month.

TODAY: Clouds eventually break for sun. Highs 33-40. Wind NW 10-20 MPH, higher gusts possible.

TONIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow inland / mix coast by late in the day. Highs 33-40. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Overcast with snow/mix transitioning to mix/rain. Snow accumulation before the change – 3-6 inches interior southern NH through central MA, 1-3 inches NH Seacoast to I-495 and I-95 belts, under 1 inch southeast of there. Temperatures slightly rising to 35-42 southern NH and central MA, 43-50 most areas except over 50 South Coast and Cape Cod. Wind E-SE 10-20 MPH, higher gusts, shifting to SW along the South Coast with an area of variable winds right along the track of the new low center.

THURSDAY: Cloudy with rain ending west to east during the morning. Breaking clouds afternoon. Highs 40-47 except 48-55 South Coast / Cape Cod. Wind variable 5-15 MPH becoming W 10-20 MPH with higher gusts expected.

THURSDAY NIGHT: Clearing. Lows 17-24. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Sun/cloud mix. Highs 32-39. Wind NW 5-15 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.

SATURDAY: Partly sunny. Chance of a passing snow shower. Highs 35-42. Wind SW 10-20 MPH, shifting to NW by late in the day.

DAYS 6-10 (JANUARY 29 – FEBRUARY 2)

Next low pressure system approaches late in the weekend on January 29. Looks like a weaker system with a low track northwest of our region, dragging a warm front / cold front combo through, so expecting more clouds to move in during Sunday and some precipitation – best shot of snow north and west with rain south and east – Sunday night into part of Monday January 30 before drier weather returns later Monday through the final day of the month on Tuesday of next week. Watching the first couple days of February for colder weather and eventually a storm threat by the end of the period. Long way to go to scope that one out.

DAYS 11-15 (FEBRUARY 3-7)

Potential storm systems to impact the region very early and again later in the period with winter weather threats as it looks like a colder pattern as well.

DAYS 1-5 (JANUARY 23-27)

A case of the Stormy Monday Blues starts our week off as the system that arrived yesterday with some light snow late yesterday and rain coast with snow well inland last night continues to impact the region during today. The center of low pressure has moved across the Islands and Outer Cape Cod over the last few hours and as it moves away today, the back side of its elongated center will be part of a trough that extends back away from the low. After more spotty mixed precipitation to the northwest and rain to the south to start the day, a steadier lobe of mix to snow will swing through the region from midday through the afternoon hours, resulting in a period of snow, expected to accumulate another 1 to 3 inches in general across southern NH and down to about I-90 and along the I-95 belt as well, with areas to the southeast of here seeing less than 1 inch of accumulation (I’ve left the storm total accumulation in the forecast section below which reads very similar to yesterday’s as areas of southern NH and north central MA have already had some accumulation from the first part of the storm, and this is included in the total there. This storm system pulls out of the region tonight and the promised break in the action comes on Tuesday as we’ll be in a drier northwesterly air flow behind the departing storm system. A cold front will be moving out of eastern Canada into New England at that time, but its snow shower activity will be confined to the mountains and we’ll only see some patchy clouds down in the WHW forecast area. A small area of high pressure in eastern Canada extends down into our area Tuesday night and very early Wednesday with dry and slightly colder weather. But the break is short-lived, as the well-advertised active pattern rolls on. The next low pressure area makes a run at the eastern Great Lakes later Wednesday and is destined to redevelop with its secondary center moving right across our region early on Thursday before moving quickly and steadily away by later Thursday. The precipitation scenario with this one will be a snow to rain event, maybe some sleet in the transition, with the typical south to north progression of a changeover line sometime Wednesday night after some areas deal with snow accumulation. A quick ending to the rain comes Thursday morning followed by dry weather later Thursday and Friday as low pressure departs and high pressure moves in.

TODAY: Overcast. Showery precipitation this morning as mostly rain but pockets of freezing rain and eventually some sleet/snow north central MA and southwestern NH. Steadier mix to snow west to east midday through afternoon. Total storm snowfall accumulation including what has fallen in northwestern portions of the area: 4-8 inches interior southern NH and north central MA with isolated amounts of greater than 8 inches possible in the highest elevations, 2-4 inches NH Seacoast down I-495 belt to I-90 region, 1 to 2 inches I-95 corridor, under 1 inch southeast of I-95 to little or nothing along the South Coast. Highs 33-40 except over 40 South Coast. Wind NE to N 10-20 MPH, strongest near the coast where higher gusts are possible.

TONIGHT: Evening snow showers possible especially eastern and southern areas, otherwise breaking clouds. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind NW 10-20 MPH, gusty.

TUESDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow inland / mix coast by late in the day. Highs 33-40. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Overcast with snow/mix transitioning to mix/rain. Temperatures steady or rising slightly. Wind E-SE 10-20 MPH, higher gusts.

THURSDAY: Cloudy with rain ending west to east during the morning. Breaking clouds afternoon. Highs 38-45 except 46-53 South Coast / Cape Cod. Wind variable 5-15 MPH becoming W 10-20 MPH.

THURSDAY NIGHT: Clearing. Lows 17-24. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Sun/cloud mix. Highs 32-39. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (JANUARY 28 – FEBRUARY 1)

Mostly dry but not totally dry weather expected for the January 28-29 weekend as we watch a cold front bring potential snow showers Saturday and an approaching warm front maybe bring some patchy snow to western and northern areas at some point Sunday, but not a “stormy” weekend. Trough / low pressure moves through with unsettled weather January 30. Generally fair and seasonably chilly weather with high pressure moving in for the final day of January and first day of February based on current timing.

DAYS 11-15 (FEBRUARY 2-6)

This is when we enter a period of seasonably cold and potentially unsettled weather with 1 or 2 systems to bring winter precipitation opportunities. Will work out timing and details as these threats get closer.

DAYS 1-5 (JANUARY 22-26)

As stated previously, I mentioned that for areas I thought may have measurable frozen precipitation that a final call would appear on Sunday morning’s blog post, and that will follow just below. I’ve made a slight adjustment southeastward on the forecast storm track, expecting the low center to pass over the outer portion of Cape Cod or the Islands Monday. The center will also be elongated, and a little westward extension of low pressure as it moves away will allow the precipitation to hang on a little longer, allowing colder air in with enough time for a swath of snow across much of the region, after a mainly rain event for a good portion of it from tonight into early Monday. But enough snow will fall for the need of some removal activity especially northwest of a Boston-Providence line. After that system moves out, we get a dry interlude for Tuesday before the next system heads in for Wednesday into part of Thursday. This system continues to present as a snow to rain event for the region, with snow hanging on longest the further west and north of Boston you go. Details on this system will be worked out over the next couple days.

TODAY: Cloudy. Patchy afternoon drizzle / snow grains. Highs 35-42. Wind variable becoming SE to S up to 10 MPH.

TONIGHT: Overcast. Precipitation arrives quickly from southwest to northeast as snow in southwestern NH and north central MA where it transitions to a mix of snow/sleet/rain overnight, a brief period of snow and/or sleet inside I-495 before going to rain, and just rain elsewhere. Lows 32-39. Wind E 5-15 MPH, higher gusts along the coast overnight.

MONDAY: Overcast. Steadiest rain early morning but may still be mixed with sleet and snow in southwestern NH and north central MA, then tapering to occasional rain/drizzle except some snow/sleet mix potential continuing in aforementioned areas to the northwest, then precipitation becoming steady again west northwest to east southeast midday on, mainly as snow, but starting as rain/mix before transitioning to snow further south. Expected snowfall accumulation: 4-8 inches interior southern NH and north central MA with isolated amounts of greater than 8 inches possible in the highest elevations, 2-4 inches NH Seacoast down I-495 belt to I-90 region, 1/2 to 2 inches I-95 corridor, under 1/2 inch southeast of I-95 to little or nothing along the South Coast. Highs 33-40 except over 40 South Coast. Wind NE to N 10-20 MPH, strongest near the coast where higher gusts are possible.

MONDAY NIGHT: Evening snow showers possible especially eastern and southern areas, otherwise breaking clouds. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind NW 10-20 MPH, gusty.

TUESDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow inland / mix coast by late in the day. Highs 33-40. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Overcast with snow/mix transitioning to mix/rain. Temperatures steady or rising slightly. Wind E-SE 10-20 MPH, higher gusts.

THURSDAY: Overcast with rain likely in the morning, possible mix far northwestern areas. Breaking clouds afternoon. Highs 36-43. Wind variable 5-15 MPH becoming NW 10-20 MPH.

DAYS 6-10 (JANUARY 27-31)

Trend to more seasonable cold. Watching for a disturbance with minor precipitation event – probably just a frontal passage – during the first part of the period and eyeing a more formidable low pressure impact potential around January 30, but the latter event is highly uncertain.

DAYS 11-15 (FEBRUARY 1-5)

Pattern trends colder. Watching a system for around February 2-3 with winter storm potential.

DAYS 1-5 (JANUARY 21-25)

A fair weather interlude is ours today, though the day starts with lots of clouds before we finally break into some sun. But as you have been hearing, we’re in an active weather pattern and the next low pressure system is heading out way. While we end up cloudy on Sunday, most of the next system’s precipitation holds off until after daylight, and the track of the next system will allow warmer air to win out again, so while we’re looking at some areas starting as frozen precipitation, it ends up as largely a rain event, but with cold air not that far away to the north and west, we may see the precipitation end as a brief period of snow or snow showers on Monday. Behind that system comes more wind, and the arrival of colder air, reinforced even more with the passage of a secondary cold front on Tuesday. This sets up a snowier potential start to the next storm system, due in here later Wednesday, but while not a certain forecast, that one probably won’t end up staying as all snow either. More on that system next update.

TODAY: Clouds give way to sun. Highs 32-39. Wind NW up to 10 MPH.

TONIGHT: Clear. Lows 11-18. Wind calm.

SUNDAY: Increasing clouds. Highs 35-42. Wind variable up to 10 MPH.

SUNDAY NIGHT: Overcast. Rain, may start as snow/sleet southern NH and interior MA especially north of I-90. Lows 28-35 early, then rising slowly. Wind E-SE 5-15 MPH, higher gusts, becoming variable to N overnight.

MONDAY: Overcast with rain morning, possibly ending as snow or snow showers from west to east by midday. Clouds break for partial sun afternoon. Highs 37-44. Wind N to NW 10-20 MPH with higher gusts, especially later in the day.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind NW 10-20 MPH, gusty.

TUESDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow/mix/rain at night. Highs 33-40. Wind NE 5-15 MPH.

DAYS 6-10 (JANUARY 26-30)

A lot of inconsistency and non-agreement in various medium range guidance (what else is new?). Overall less stormy in general, but still have to keep an eye on things for at least 1, possibly 2 disturbances. Temperatures a little closer to seasonal levels, but still no major cold expected.

DAYS 11-15 (JANUARY 31 – FEBRUARY 4)

Pattern trends colder. Watching a system for around February 2-3 with winter storm potential.

DAYS 1-5 (JANUARY 20-24)

Part 1 of the storm system is done, having produced mostly rain and some sleet initially, then a turn to snow in areas to the north, as expected, with up to an inch or 2 of accumulation from the initial burst of snow in those areas. Today, the upper low portion of the system comes across with numerous to widespread snow showers and another couple inches accumulation in northern areas and up to around an inch in some areas to the south, and less than 1 inch for most areas south of I-90 to nothing along the South Coast where it will take longest for what starts as rain showers to transition to mix/snow showers, and by then the moisture will have generally exited the region. This will happen this evening as drier air arrives and sets up an “ok” Saturday, not totally sunny, but precipitation-free and not too cold. But the active pattern rolls on and the next storm arrives later Sunday into Monday. Guidance has trended slightly colder with this over the last few runs, and we’ll continue to watch this, but for now expecting a rain event for the coast, rain/mix/snow potential inland, but just where and how much frozen precipitation is still unclear at this point. This will be addressed on the weekend blog forecast posts. After that second storm system, another small area of high pressure brings a break with fair weather for Tuesday. Also of note, the next few days high tides will cause at least minor flooding in prone areas at is one of the higher tides of 2023, astronomically.

TODAY: Cloudy. Scattered snow showers except rain showers to the south morning. Numerous to widespread snow showers except rain showers changing to snow showers to the south. Additional snow accumulation expected (see discussion for amounts). Highs 30-37 north, 37-44 south, occurring this morning and midday, with a slow fall to follow. Wind N up to 10 MPH.

TONIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

SUNDAY NIGHT: Overcast. Rain likely except rain/mix/snow possible southern NH and portions of interior MA. Lows 32-39. Wind E 10-20 MPH, possibly stronger in coastal areas.

MONDAY: Overcast with rain to start, except mix/snow possible some inland locations, tapering off to rain and snow showers then ending. Breaking clouds follow. Highs 37-44. Wind SE or variable 10-20 MPH with higher gusts, shifting to W with stronger gusts especially by late in the day.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind variable 5-15 MPH.

DAYS 6-10 (JANUARY 25-29)

Next storm potential January 25 can produce a variety of precipitation, but unknown until the storm’s track is more clearly known. Quieter period of weather begins after that one but probably a bit colder than we’ve been. Projection of a weaker disturbance passing by somewhere near the end of the period.

DAYS 11-15 (JANUARY 30 – FEBRUARY 3)

Quiet weather for the early portion of the period, and more seasonably chilly as well. Watching a storm threat way out there in time for around Groundhog Day.

DAYS 1-5 (JANUARY 19-23)

An active weather pattern continues and we’ll be dealing with two storms during the next 5 days. The first one heads into our region today and lingers through Friday. It takes place as low pressure heading into the eastern Great Lakes redevelops off the northern Mid Atlantic Coast, just south of New England, and heads eastward. With a little more cold air around than in some of our recent events, we have a rain/snow line to deal with. Precipitation arrives toward dusk for areas to the west and near or just after dusk further east, mainly as rain but some mix/snow near and north of the MA/NH border, where it will remain steady state for the first few hours, before the rain/snow line begins a trek to the south during the late evening and overnight hours. The first batch of precipitation will taper off during the overnight, but not before a burst of moderate to heavy snow brings some accumulation to southern NH and a good portion of northern MA. After the surface storm departs, we still have the upper level low to go through the region on Friday from west to east, as the colder air continues to push southward, so this time the rain/snow line will continue further south and across the MA South Shore and the South Coast regions. The precipitation with the Friday portion of the system will not be as heavy, but it will be enough to add to the snow already on the ground to the north, and introduce some accumulation heading further south as well. When this system is done by later Friday evening, ending as snow showers, I expect that a solid 3-6 inches will have fallen across southern NH and northern MA, mainly north of the Route 2 / I-95 belt, with even a few 6+ amounts in higher elevations of north central MA and southwestern NH. We get a break Saturday between systems, a fair weather day with a narrow area of high pressure, and then the next system approaches during Sunday. There are still some questions with this one, but current indications are that the track of low pressure will cut more across our region, allowing enough warming so that more rain than snow will be involved, although we’d have to watch for snow at the start and possibly the end, especially for northern and western portions of the area. Of course, fine-tuning will be done for this event during the next few days with a solid final call by Sunday’s blog post. This system lingers into Monday before we see improvement arriving, but the departure of that system may come with quite a bit of wind as well.

TODAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible sleet and snow interior northern MA and southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

TONIGHT: Overcast. Sleet/snow southern NH and northern MA, rain to the south, slowly transitioning to mix/snow into the Route 2 / I-95 region of northern and northeastern MA while remaining mostly rain to the south, tapering off overnight. Lows 30-37. Wind NE 10-20 MPH.

FRIDAY: Cloudy. Periodic snow, except rain/mix turning to snow southern areas. Temperatures steady 30-37. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

SUNDAY NIGHT: Overcast. Rain likely except rain/mix/snow possible southern NH and interior northern MA. Lows 32-39. Wind E to SE 10-20 MPH, possibly stronger in coastal areas.

MONDAY: Overcast with rain to start, tapering off to showers then ending. Breaking clouds follow. Highs 40-47. Wind SE to SW 15-25 MPH, shifting to W with higher gusts especially later in the day.

DAYS 6-10 (JANUARY 24-28)

Next storm potential around January 25 can produce a variety of precipitation, but may end up being a colder storm than the previous one. Quieter period of weather begins after that one but probably a bit colder than we’ve been.

DAYS 11-15 (JANUARY 29 – FEBRUARY 2)

Quiet weather for the early to middle portion of the period, and more seasonably chilly as well. Watching a storm threat for later in the period.

DAYS 1-5 (JANUARY 18-22)

An upper level trough and surface cold front swings through the region this morning and midday with lots of clouds and the threat of a rain shower, followed by fair weather the rest of the day, and still mild despite a gusty breeze. A small area of high pressure brings more traquil and dry weather overnight into early Thursday, but clouds advance quickly on Thursday ahead of the next low pressure system. The initial primary low center is destined for the eastern Great Lakes but will redevelop near or just south of the New England South Coast Thursday night and early Friday as it tracks to the east. This will be followed by the trough which remains of the old low during Friday, drawing out this unsettled period, which will also have frozen precipitation involved. A rain/snow line should be present at the start of the event with snow in interior northern MA and southern NH, rain elsewhere. This rain/snow line will waver around, probably heading north for a time before coming back to the south, then progressing even further south on Friday as we transition from steadiest precipitation into more occasional. The change-over will probably not quite make it all the way through the South Coast region before the end of the precipitation. This sets up a snow (and some sleet) accumulation profile that by the time we wind things up on Friday evening will look like this: traces / coatings of snow south of I-90, but maybe up to 1 inch in the higher elevations of south central MA, northwestern RI, and northeastern CT, a general 1-3 inch snowfall north of I-90 except 3-5 inches north central MA and southern NH. The weekend starts off fair with high pressure moving in during Saturday, then ends with a return to unsettled weather as low pressure approaches on Sunday, spreading a shield of rain in that may start as mix/snow for some inland areas by late in the day or evening, based on current expecting timing.

TODAY: Mostly cloudy to partly sunny. A passing rain shower possible through midday. Highs 45-52. Wind W 5-15 MPH this morning, NW 10-20 MPH with possible higher gusts this afternoon.

TONIGHT: Partly cloudy to mostly clear. Lows 24-31. Wind W under 10 MPH.

THURSDAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible sleet and snow interior northern MA and southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely with greatest chance of frozen/mix I-495 west south of I-90, and I-90 north otherwise. Lows 31-38. Wind NE 10-20 MPH.

FRIDAY: Mostly cloudy. Periods of rain/mix South Coast, periods of snow elsewhere, tapering with time. Highs 33-40. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

DAYS 6-10 (JANUARY 23-27)

Stormy start January 23 with low pressure cutting across the region, based on current expectations. Should have warmed up enough for mostly rain but will keep an eye on it. Dry interlude briefly between that system and the next one expected in the January 25-26 window – will fine-tune that. Drier/chilly weather to end the period behind that system.

DAYS 11-15 (JANUARY 28 – FEBRUARY 1)

A quieter, more seasonably chilly period of weather is anticipated here with maybe one minor disturbance bringing a snow shower risk.

DAYS 1-5 (JANUARY 17-21)

We will see a rare appearance of full sunshine for several hours today as we’re in an area of dry air behind the now-departed ocean storm, but clouds will be moving in quickly this afternoon ahead of the next low, approaching from the Midwest / northern Mid Atlantic. This system will be weakening and its precipitation shield may survive as a small area of light rain this evening before dissipating. The system will be in the process of being absorbed by the ocean storm Wednesday as we find ourselves in a northwesterly air flow behind it, with dry weather and a gusty breeze, but on the mild side since there is not really any cold air to be tapped just yet. A weak area of high pressure moves across the region Wednesday night into early Thursday with tranquil weather, but in this active pattern the next low, this one more formidable, makes its way into the Northeast during Thursday and Thursday night with extensive cloud cover and a shield of precipitation. The set-up for that system is a bit more complex, as at that time we’ll have colder air starting to press in from the north. While I think most start as rain (maybe some mix in southern NH), we likely see a transition to a larger area of sleet and snow where north of and up to the I-90 belt, but not exactly sure on timing and location for a rain/sleet/snow zones. That will be monitored and fine-tuned over the next couple days. This will be an elongated system with a trough behind the initial low passing through on Friday with additional precipitation, probably mostly snow showers, except rain/mix/snow to the south closer to the South Coast. Drier weather should be back with us for the start of the weekend.

TODAY: Sun followed by clouds. Highs 39-46. Wind variable to W 5-10 MPH.

TONIGHT: Mostly cloudy. A period of light rain possible during the evening. Lows 32-39. Wind S up to 10 MPH.

WEDNESDAY: Mostly cloudy to partly sunny. Highs 45-52. Wind NW 5-15 MPH, a few higher gusts.

WEDNESDAY NIGHT: Partly cloudy to mostly clear. Lows 24-31. Wind W under 10 MPH.

THURSDAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible rain/sleet/snow mix southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely with greatest chance of frozen/mix in northern areas. Lows 31-38. Wind NE 10-20 MPH.

FRIDAY: Mostly cloudy with mix/snow showers likely. Highs 35-42. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 22-26)

Low pressure impact potentials January 22 into January 23, and again late in the period as we remain in an active pattern. Too soon to determine disturbance intensity and precipitation type. Temperatures mostly above normal, though variable.

DAYS 11-15 (JANUARY 27-31)

General pattern looks like it leaves the door open for more seasonable cold, at least in 1 or 2 shots with passing disturbances originating further north than previously, but some guidance suggest one potential more substantial precipitation producer coming from Gulf of Mexico moisture, so that will be something to keep an eye on in the days ahead.

DAYS 1-5 (JANUARY 16-20)

A lobe of snow and some sleet will move quickly north to south this morning across the region on the back side of a complex ocean storm to our south and east. Some lingering rain and snow showers may be near coastal areas into this afternoon as well. The entire conglomeration moves more seaward away from New England later today onward, losing its grip on this region, but making way for another low pressure area approaching via the Midwest by later on Tuesday. This system, feeling the effects of the larger offshore circulation, will begin to yield to it and weaken, but its weakening precipitation shield will cross our region Tuesday evening, but not before we sneak in a few hours of nice weather to start the day on Tuesday. Behind this system a small area of high pressure builds in with fair weather Wednesday, but it will be on the mild side – definitely the pick of the week for combined dry and mild weather. Thursday also starts out nice, but clouds move in ahead of the next low pressure system heading our way from the Midwest and Ohio Valley. This is another system that originated in the active Pacific jet stream pattern. For us it will come along with mild enough air so that despite some mix/snow potential at the start, it will likely end up as mostly a rain event. But as the surface storm starts to move out on Friday we’ll still have to deal with upper level low pressure and somewhat cooler to colder air, so precipitation will probably go over to mix/snow showers as we remain unsettled that day, continuing the overall pattern we’ve seen so far this first month of 2023 which lacks sun and doesn’t lack low pressure moving through the region.

TODAY: Cloudy start with a period of snow and sleet moving north to south across the region, may be heavy for a brief time, then lots of clouds with occasional snow and rain showers favoring eastern areas, tapering off later in the day. Highs 35-42. Wind N to NW 10-20 MPH, higher gusts especially coastal areas.

TONIGHT: Clearing. Lows 25-32. Wind NW to W diminishing to under 10 MPH.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 45-52. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 23-30. Wind variable under 10 MPH.

THURSDAY: Sun followed by clouds. Late-day snow/mix/rain possible. Highs 40-47. Wind variable to E up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely. Lows 32-39. Wind E 10-20 MPH.

FRIDAY: Mostly cloudy with mix/snow showers lingering. Highs 35-42. Wind N 10-20 MPH.

DAYS 6-10 (JANUARY 21-25)

Storm signal around January 23 (late 1-22 to early 1-24) – the last in the long-running Pacific parade. Too soon for details. Dry weather either side. Temperatures near to above normal.

DAYS 11-15 (JANUARY 26-30)

Overall drier, cooler trend but no signal for major cold at this point. Still will see a couple disturbances coming by but the origin is a little different than previously – systems translating across the country that have come into North America a little further north and with less moisture than we saw in the previous pattern. A couple of those bring precipitation opportunities for this region sometime during the final week of the month. Overall cooling trend in temperature but still no signal for major cold in this region.

DAYS 1-5 (JANUARY 15-19)

Our region will be on the fringes of a large ocean storm today into Monday, but this storm’s main impact will be at sea, offshore. The fringe effects for southeastern New England will include some rain and snow for mainly southeastern MA and Cape Cod, along with gusty winds, especially in coastal areas, strongest also over southeastern MA and Cape Cod into Monday, before the low center starts to pull away to the east. While drier and colder air working southward into New England from eastern Canada will trend any precipitation to snow after the initial rain and mix, the dry air will also eat away at the western edge of the synoptic precipitation. Some ocean-effect mix to snow bands will likely occur from the South Shore surviving to the South Coast and across Cape Cod during this time. As far as model depiction goes, caution for model watchers that the global guidance at this range tends to over emphasize the precipitation area and how far west it gets, and the higher resolution shorter range guidance is likely a better representation of how the system plays out. Measurable snowfall should be confined mostly to the South Shore down into Cape Cod (after the wetter start there), with mainly traces of mix to snow with some minor accumulation working back into the I-95 belt and a few flurries of snow out into the I-495 belt from drying synoptic snowfall. Some sunshine may even appear at times over inland locations from south central and southwestern NH through central MA into eastern CT and possibly even RI as drier air wraps around the back side of the offshore storm, and we should see an increase in the sunshine further east as the system pulls further away by later Monday. But any clearing will be rather short-lived, as the next low pressure system from the west will spread its clouds into the region during Tuesday. As previously indicated, this system will be feeling the effect of the dry air behind the ocean storm, and will begin to fall apart, with maybe a little bit of rain and mix surviving into our region Tuesday evening as milder air also arrives. A small area of high pressure is expected to bring fair weather and somewhat above normal temperatures to our region at midweek. Currently, I am leaning toward a slower arrival of the next system behind that, which has been modeled to impact our region on Thursday, but I feel may not arrive until after we reach the end of this 5-day forecast period. Will monitor that and readjust the timing if necessary.

TODAY: Mainly cloudy – heaviest clouds eastern areas, partial sun possible well inland. Periods of rain and mix transitioning to mix and snow MA South Shore through Cape Cod working into the South Coast region of MA. Highs 35-42. Wind NE 10-20 MPH, higher gusts especially coastal areas.

TONIGHT: Mainly cloudy. Mix/snow most likely Cape Cod, South Coast and South Shore of MA where a general coating to 2 inches of snow is likely, with isolated amounts up to 3 inches possible in some South Shore areas. Snow showers from I-95 to I-495 belts with under 1 inch of accumulation. Lows 26-33. Wind N 10-20 MPH, gusts 25-45 MPH, strongest coastal areas.

MONDAY: Mostly cloudy eastern coastal areas with snow showers early, otherwise increasing sun from west to east gradually. Highs 34-41. Wind N to NW 10-20 MPH, higher gusts, especially in coastal areas.

MONDAY NIGHT: Partly cloudy. Lows 25-32. Wind NW to W diminishing to under 10 MPH.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 46-53. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 23-30. Wind variable under 10 MPH.

THURSDAY: Sun and high clouds. Highs 42-49. Wind variable to SE up to 10 MPH.

DAYS 6-10 (JANUARY 20-24)

Low pressure systems should impact the region with precipitation threats January 20, 22, and 24, based on current timing, the final systems in a Pacific parade as the pattern starts to change, shutting off the Pacific flow. Temperatures above normal, although variable.

DAYS 11-15 (JANUARY 25-29)

The pattern heading into the late days of the month looks a little less active with more high pressure in control across the Great Lakes and Northeast, and one or two frontal boundaries bringing brief, minor precipitation threats. Temperatures near to above normal with a couple colder shots, but nothing extreme.

DAYS 1-5 (JANUARY 14-18)

A mainly dry MLK Weekend, though lacking in sunshine, for most areas. One exception is this morning, as a disturbance passes through, some light precipitation in the form of rain, sleet, and in some areas snow grains (which just dusted cold surfaces here in Woburn before I wrote this). Low pressure moving off the Mid Atlantic meanders well south to well east of New England, but with a large circulation we will be in its envelope of northeast to north wind during Sunday and Monday, and some of its precipitation will wheel into the Cape Cod and southeastern MA region mainly from early Sunday to early Monday. With a mild ocean temperature and marginal air temperatures anyway there will be a fine line between liquid and frozen precipitation where it occurs, with a gradual trend from liquid to frozen overall. With a touch of ocean-enhancement, a slow-occurring snow accumulation of up to 3 inches may occur in southeastern MA during this time before the low starts to pull away. While it does that, it sheds some of its synoptic precipitation westward, but this is usually overdone by models and I am not expecting much of an impact other than some sprinkles / flurries over other portions of eastern MA up to around the NH Seacoast, especially Sunday afternoon and night. But for most locations, this will be a mainly dry 3-day stretch of weather. The next system moves in from the west by Tuesday, but will be undergoing a weakening trend due to the larger system well offshore, so we’ll have lots of clouds coming back after a brighter start to the day, but if any precipitation survives it would likely fall as a light mix of rain/snow or just light rain sometime that evening before vanishing. This leaves us with a fair and milder Wednesday as high pressure moves into the region, but not from a cold weather source region.

TODAY: Cloudy morning with areas of drizzle, very light rain, sleet, and snow grains. Mostly cloudy afternoon. Highs 37-43. Wind NW-N increasing to 10-20 MPH.

TONIGHT: Variably cloudy. Lows 25-32. Wind N 10-20 MPH, higher gusts.

SUNDAY: Mostly cloudy. Episodes of rain and snow Cape Cod and southeastern MA where some minor snow accumulation is possible inland southeastern MA. Highs 35-42. Wind N-NE 10-20 MPH, higher gusts especially coastal areas.

SUNDAY NIGHT: Mostly cloudy. Additional snow/mix showers southeastern MA and Cape Cod with additional minor snow accumulation. Lows 27-34. Wind N 10-20 MPH, higher gusts near the coast.

MONDAY: Partly sunny. Additional morning rain/snow possible southeastern MA. Highs 35-42. Wind N 5-15 MPH, higher gusts especially near the coast.

MONDAY NIGHT: Variably cloudy. Lows 25-32. Wind NW up to 10 MPH becoming variable.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 46-53. Wind W up to 10 MPH.

DAYS 6-10 (JANUARY 19-23)

We’ll start to see a transition out of the Pacific flow pattern, but not a quick change, so we still have 2 shots at precipitation from the last couple systems, around January 19 and 22, based on current timing. Temperatures above normal overall, but somewhat variable.

DAYS 11-15 (JANUARY 24-28)

Less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern evolving, but still lacking strong cold shots. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available.

DAYS 1-5 (JANUARY 13-17)

Low pressure tracks into eastern Canada today and its cold front moves across the region. It will be a mild day with rain showers around, but the heaviest band of rain occurs early in southeastern areas. Drier air works in later today and tonight. Complete clearing will be hard to come by though as the front is not that far offshore Saturday, and while it’s precipitation-free, we can expect a lot of clouds to hang around to start the long weekend. As we move through the weekend, we’ll watch the development and evolution of a new storm to the south and southeast of New England, in a slow-moving upper air pattern. The storm will be close enough to impact the region with a northeast to north wind, and may toss some rain and snow showers back into coastal areas, especially during a portion of Sunday, but the precipitation from this will largely remain offshore. Bands of precipitation that radiate outward from the low will run into dry air and dissipate in the process of doing so, but this may add to the cloudiness as there are a lot of mid and high level clouds associated with this system that can expand over the region. We will have to watch for a band or two of ocean effect mix/snow showers as well especially for the South Shore and Cape Cod. This system should be heading back out by Monday with fair weather, but the previously talked about tranquility may be a bit delayed since we may still be under the influence of the low’s wind circulation and the high from the west will be in the process of getting squeezed between that storm and an approaching low pressure area from the Midwest. The latter of the two will start to impact our region on Tuesday, but it will also be feeling the influence of the much larger ocean storm and will likely begin a process of weakening, eventually to be absorbed by that circulation offshore. So its impact on us may be more in the form of cloudiness than precipitation.

TODAY: Cloudy morning with widespread rain showers southeastern MA into mid morning, otherwise scattered rain showers through the morning. Mostly cloudy this afternoon with an additional rain shower possible. Highs ranging from 45-52 in far north central MA and southwestern NH to 53-60 elsewhere. Wind S 10-20 MPH except 15-30 MPH southeastern MA, higher gusts in all areas, shifting to W during the day, with the exception of an area of lighter and variable wind this morning where it is cooler well northwest of Boston.

TONIGHT: Mostly cloudy. Lows 30-37. Wind W to NW 10-20 MPH, gusty.

SATURDAY: Lots of clouds, breaks of sun. Highs 37-43. Wind NW-N 10-20 MPH, gusty.

SATURDAY NIGHT: Variably cloudy. Lows 25-32. Wind N 10-20 MPH, higher gusts.

SUNDAY: Variably cloudy. Rain/snow showers possible in coastal locations. Highs 35-42. Wind N-NE 10-20 MPH, higher gusts especially coastal areas.

SUNDAY NIGHT: Mostly cloudy. Additional snow/mix showers possible near the coast. Lows 25-32. Wind N under 10 MPH.

MONDAY: Partly sunny. Highs 35-42. Wind N 5-15 MPH, higher gusts especially near the coast.

MONDAY NIGHT: Variably cloudy. Lows 25-32. Wind NW up to 10 MPH becoming variable.

TUESDAY: Mostly cloudy. Light rain/mix/snow possible. Highs 38-45. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 18-22)

Next low pressure threat around mid period, trends a little weaker on guidance at this time possibly in response to lingering offshore low pressure and lack of support, but will watch it for a snow/mix/rain threat. Dry before it and after it. Temperatures near to above normal – no major cold.

DAYS 11-15 (JANUARY 23-27)

Less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern, but still lacking strong cold shots. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available, depending on the set-up.

DAYS 1-5 (JANUARY 12-16)

A little surprise ocean-effect snow from Boston into the northwestern suburbs and the North Shore with low level moisture moving in from the southeast overnight with air cold enough to support flakes. We’ve had a minor accumulation / coating, just enough to slick up some roads and walks that were not treated, so be cautious if you have to travel early today before the temperature goes above freezing and it all vanishes. During the day today, with the approach of a warm front, we will still be under an overcast with scattered light precipitation, back to rain for the coastal plain and I-95 belt with a bit of freezing rain in pockets off to the northwest and snow well to the northwest, as mentioned on yesterday’s discussion. Still expecting the system passing to our northwest to give us most of its rain in the warm sector later tonight into Friday morning before the cold front pulls through and we start a dry-out process during the afternoon on Friday. A developing storm on the offshore front will tease far eastern New England with some clouds at times this weekend, and the rain/snow shield may make a run for outer Cape Cod briefly, but I expect it to stay offshore and keep the region dry between the storm and high pressure to the west, the latter of which will move in for MLK Jr Day on Monday with fair and more tranquil weather after a gusty breeze during Saturday and Sunday.

TODAY: Cloudy. Spotty light rain that may freeze on some surfaces well northwest of Boston and be in the form of snow for a while from southwestern NH into central MA before all transitioning to rain later. Highs 36-43. Wind E up to 10 MPH.

TONIGHT: Cloudy. Periods of rain including embedded heavier showers with the chance of thunder. Areas of fog developing. Temperatures rising through the 40s. Wind SE 5-15 MPH, gusts 20-25 MPH, strongest coast where gusts above 30 MPH are possible.

FRIDAY: Cloudy morning with numerous showers and a slight chance of thunder, especially southeastern NH through eastern MA and RI. Breaking clouds with partial sun possible midday on. Highs 48-55. Wind SW 10-20 MPH with higher gusts, shifting to W.

FRIDAY NIGHT: Partly cloudy. Lows 28-35. Wind NW 10-20 MPH, higher gusts in the evening, shifting to N.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind N 10-20 MPH, higher gusts especially coastal areas.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind N 10-20 MPH, higher gusts especially coastal areas.

SUNDAY: Mostly sunny. Highs 33-40. Wind N 10-20 MPH, higher gusts especially coastal areas, diminishing later in the day.

SUNDAY NIGHT: Clear. Lows 15-22. Wind N under 10 MPH.

MONDAY: Sunny. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 17-21)

Low pressure may still linger offshore early in the period and make a loop back, essentially dismantling an approaching front from the west on January 17, so we may end with lots of clouds but not much, if any, precipitation from that system, followed by high pressure with dry weather for a couple days. Another storm system from the west may move in later in the period with a rain/mix/snow threat, but this is low confidence.

DAYS 11-15 (JANUARY 22-26)

A little less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available, depending on the set-up.
