7:11AM

DAYS 1-5 (JANUARY 30-FEBRUARY 3)
We end January with one dry and seasonably chilly day and another dry and slightly milder day as high pressure moves across the region then offshore and away. We will start February with a slightly unsettled weekend and by slightly I mean being skirted by the northwestern edge of a broad low pressure area offshore Saturday bringing a little rain and possible mix into southeastern sections, and some upper level energy coming across Sunday with slightly colder air in place, resulting in the possibility of some snow showers in the region. High pressure will bring fair weather Monday and we’ll already be moderating in temperature by then as things are moving right along.
Forecast details…
TODAY: Mostly sunny. Highs 30-37. Wind N up to 10 MPH.
TONIGHT: Mostly clear. Lows 13-20. Wind variable under 10 MPH.
FRIDAY: Partly cloudy. Highs 37-44. Wind variable up to 10 MPH.
FRIDAY NIGHT: Clouding over. Lows 26-33. Wind E 5-15 MPH.
SATURDAY: Cloudy. Chance of mix/rain favoring eastern CT/RI/southeastern MA. Highs 35-42. Wind E 10-20 MPH, higher gusts southern areas.
SATURDAY NIGHT: Mostly cloudy. A rain or snow shower favoring southeastern areas. Lows 30-37. Wind N 5-15 MPH.
SUNDAY: Variably cloudy. Chance of a snow shower. Highs 35-42. Wind W 5-15 MPH.
SUNDAY NIGHT: Clearing. Lows 20-27. Wind NW 5-15 MPH.
MONDAY: Mostly sunny. Highs 38-45. Wind W 5-15 MPH.

DAYS 6-10 (FEBRUARY 4-8)
Milder then average throughout the period though some variability in temperature, with warmest likely occurring on February 4. A couple low pressure areas will impact the region, the first in the February 4-5 period with rain showers as mild air dominates, the second sometime in the later February 6 to February 8 period which may have more of a mix involved as slightly colder air will be present by then.

DAYS 11-15 (FEBRUARY 9-13)
Fair weather to start this period then being near a boundary between mild air in the southeastern US and colder air in eastern Canada means we’ll likely turn unsettled again for the balance of this period, although it’s far too soon to detail what any storminess may produce as far as precipitation type goes.

7:24AM

DAYS 1-5 (JANUARY 29-FEBRUARY 2)
High pressure brings fair and a bit more of a chill to the area today and Thursday, certainly not “cold” by January standards, but feeling a little more seasonable than much of the month has. High pressure continues to dominate through Friday, which will be a little milder. This will end the month on a quiet note. As February arrives we’ll immediately be watching a storm system but at the moment I feel the bulk of this will pass offshore to the southeast of New England, not being able to link with energy dropping through the Great Lakes in time to form a more significant storm to impact the region, so going with rain (maybe mix) confined to southeastern portions of the region with little or nothing to the north and northwest as the initial system passes by on Saturday. Slightly colder air arriving with the energy from the Great Lakes passing by on Sunday may produce a few snow showers. There is still just enough uncertainty that we have to watch that initial storm should it end up closer.
Forecast details…
TODAY: Early morning clouds depart north to south, otherwise mostly sunny. Highs 33-40. Wind N 5-15 MPH.
TONIGHT: Mostly clear. Lows 13-20. Wind N up to 10 MPH.
THURSDAY: Mostly sunny. Highs 30-37. Wind N up to 10 MPH.
THURSDAY NIGHT: Mostly clear. Lows 12-19. Wind variable under 10 MPH.
FRIDAY: Partly cloudy. Highs 35-42. Wind variable up to 10 MPH.
FRIDAY NIGHT: Clouding over. Lows 25-32. Wind NE 5-15 MPH.
SATURDAY: Cloudy. Chance of mix/rain favoring eastern CT/RI/southeastern MA. Highs 35-42. Wind E 10-20 MPH, higher gusts southern areas.
SATURDAY NIGHT: Mostly cloudy. A rain or snow shower favoring southeastern areas. Lows 30-37. Wind N 5-15 MPH.
SUNDAY: Variably cloudy. Chance of a snow shower. Highs 35-42. Wind W 5-15 MPH.

DAYS 6-10 (FEBRUARY 3-7)
Fair, chilly February 3. Unsettled weather potential February 4-5, and again later February 6 or February 7. Too early to know precipitation type for those threats but temperatures will still likely be running above seasonal averages for the first week of February overall.

DAYS 11-15 (FEBRUARY 8-12)
Unsettled weather threats very early and again late in the period. Temperatures gradually trend colder with a slow pattern transition underway.

7:24AM

DAYS 1-5 (JANUARY 28-FEBRUARY 1)
A cold front drops north to south through the region today as a pool of chilly air continues to move through aloft, causing lots of clouds. A few flurries may occur mainly this morning. A band of snow showers may impact the southern portion of the South Shore (south of Plymouth MA) across Cape Cod with a minor accumulation of snow this evening and tonight as colder air blows over relatively warmer water. High pressure north of the region will create a chilly northerly air flow for midweek but with dry weather, but as the high slips to the southeast it will moderate a little with continued dry weather on Friday, to end January. As February arrives Saturday we’ll be watching for the arrival of a possible storm system that brings the chance of rain and/or snow. At this point it remains uncertain as to the magnitude of impact from this potential system. Will fine-tune this in the next few days.
Forecast details…
TODAY: Mostly cloudy. Brief passing light snow showers possible through midday. Highs 37-43. Wind N 10-20 MPH.
TONIGHT: Variably cloudy. Snow showers with minor accumulation possible south of Plymouth MA through Cape Cod. Lows 20-27. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 32-39. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 13-20. Wind N up to 10 MPH.
THURSDAY: Mostly sunny. Highs 30-37. Wind N up to 10 MPH.
THURSDAY NIGHT: Mostly clear. Lows 12-19. Wind variable under 10 MPH.
FRIDAY: Partly cloudy. Highs 35-42. Wind variable up to 10 MPH.
FRIDAY NIGHT: Clouding over. Lows 25-32. Wind NE 5-15 MPH.
SATURDAY: Cloudy. Chance of snow/mix/rain. Highs 33-40. Wind NE 10-20 MPH, higher gusts.

DAYS 6-10 (FEBRUARY 2-6)
Surface low pressure that may impact the region the day before should be departing but upper level low pressure crossing New England may cause snow showers February 2. After a break February 3, another weather system brings the risk of precipitation February 4 followed by another at the end of the period. Temperatures will run above seasonal averages.

DAYS 11-15 (FEBRUARY 7-11)
Potentially 2 more low pressure systems around February 8 and February 10-11. Temperatures should be trending colder at this time.

7:35AM

DAYS 1-5 (JANUARY 27-31)
A quiet final 5 days of January as high pressure will be in general control. There will be lots of cloudiness around today however to start the week as upper level energy moves through the region, and a weak cold front will pass by later Tuesday bringing somewhat colder air into the region as well, also possibly bringing a touch of snow shower activity to outer Cape Cod. But those would be the only flakes to possibly be seen in the area for the next several days.
Forecast details…
TODAY: Mostly cloudy. Highs 38-45. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Lows 22-29. Wind NW up to 10 MPH.
TUESDAY: Partly sunny. Highs 37-43. Wind N 10-20 MPH.
TUESDAY NIGHT: Partly cloudy. Possible snow showers outer Cape Cod. Lows 20-27. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 32-39. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 13-20. Wind N up to 10 MPH.
THURSDAY: Mostly sunny. Highs 30-37. Wind N up to 10 MPH.
THURSDAY NIGHT: Mostly clear. Lows 12-19. Wind variable under 10 MPH.
FRIDAY: Partly cloudy. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (FEBRUARY 1-5)
Weather pattern gets a little more active as we start February with storm threats on the February 1-2 weekend and also February 4-5. In each case it’s far too soon for much detail, but the weekend system at least as some risk of having frozen precipitation involved with it.

DAYS 11-15 (FEBRUARY 6-10)
Another opportunity for storminess around the middle of the period.

8:06AM

DAYS 1-5 (JANUARY 26-30)
This is basically going to be the same blog as yesterday, with yesterday removed, and the days shuffled up, mainly because I see absolutely no need to change a thing today. To summarize, dry air returns today, high pressure dominates much of the week, no arctic cold, but a little more seasonably chilly at times as we head through the next several days.
Forecast details…
TODAY: Partly sunny. Highs 43-50. Wind W 10-20 MPH, higher gusts.
TONIGHT: Partly cloudy. Lows 23-30. Wind W 5-15 MPH.
MONDAY: Mostly sunny. Highs 38-45. Wind W 5-15 MPH.
MONDAY NIGHT: Mostly clear. Lows 22-29. Wind NW up to 10 MPH.
TUESDAY: Partly sunny. Highs 37-43. Wind N 10-20 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 35-42. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 15-22. Wind N up to 10 MPH.
THURSDAY: Mostly sunny. Highs 32-39. Wind N up to 10 MPH.

DAYS 6-10 (JANUARY 31-FEBRUARY 4)
High pressure should hold on for dry weather to end January. Continuing to watch the February 1-2 weekend for a possible storm threat. Fair, chilly interlude after that before another threat appears at the end of the period.

DAYS 11-15 (FEBRUARY 5-9)
Departing low pressure with dry weather returning early period, a mid period unsettled threat, and then dry and colder to end it.

9:21AM

DAYS 1-5 (JANUARY 25-29)
Our pattern recently has to been spread out the storm systems and get longer stretches of quiet weather, and that will be the case for a while. We dealt with some storminess mainly in the form of snow with some rain to the south last weekend, and this weekend we will deal with another passing low pressure area of fairly short duration, but this time all rain as we have mild air in place. We’ll essentially see this event over about a 6 to 10 hour period tonight, but during its peak it will produce a pretty good slug of rain, and even possibly some thunder. So if you have Saturday night plans be ready for rain, but at least you don’t have to plan for snow or ice. This system, which consists of a parent low moving into the Great Lakes and a secondary low which will form near the Delmarva and move right across southern New England, will be out of here quickly Sunday morning, leaving southeastern New England in a drying westerly air flow during the day. However, we won’t see a blast of cold coming in right behind this system as we often do during winter. This time mild air follows it. Somewhat colder air will filter into the region during the first few days of the coming week, helped out a little by a quietly passing cold front on Tuesday and high pressure in eastern Canada. Previously I had snow showers in the forecast for the Tuesday system, but at the moment it appears that will slip through here without enough moisture to work with to produce any snow showers, just some clouds.
Forecast details…
TODAY: Cloudy. Patchy rain mid to late afternoon. Highs 40-47. Wind SE increasing to 10-20 MPH with higher gusts, strongest at the coast.
TONIGHT: Cloudy through late evening with rain, likely moderate to heavy for a period of time which may also include a thunderstorm. Breaking clouds overnight. Temperature rise slightly to 45-52 evening. Overnight lows 36-43. Wind variable 5-15 MPH evening, W 10-20 MPH overnight.
SUNDAY: Partly sunny. Highs 43-50. Wind W 10-20 MPH, higher gusts.
SUNDAY NIGHT: Partly cloudy. Lows 23-30. Wind W 5-15 MPH.
MONDAY: Mostly sunny. Highs 38-45. Wind W 5-15 MPH.
MONDAY NIGHT: Mostly clear. Lows 22-29. Wind W up to 10 MPH.
TUESDAY: Partly sunny. Highs 37-43. Wind W 10-20 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind NW 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 35-42. Wind N 5-15 MPH.

DAYS 6-10 (JANUARY 30-FEBRUARY 3)
High pressure should hold on for day weather the last couple days of January. Watching the February 1-2 weekend for a possible storm system, this one having colder air to work with and a greater risk of having some snow/ice involved. Fair, colder to end the period.

DAYS 11-15 (FEBRUARY 4-8)
Potential stormy periods at the beginning an end of the period, with fair and seasonably cold weather between.

7:20AM

DAYS 1-5 (JANUARY 24-28)
High pressure heads offshore today and we will see some cloudiness as a frontal boundary will be in the region, but not with enough moisture to produce any precipitation. Things will change in short order tomorrow afternoon as low pressure wheels into the Great Lakes and a secondary forms and comes right up over southeastern New England at night, bringing a slug of rain, and maybe even a rumble of thunder. There will simply not be enough cold air around for anything other than rain. Drier air returns on Sunday outside the risk of a passing rain shower as colder air will not return quickly enough or in any force enough to create snow showers behind this system either. A more seasonably chill arrives for the early part of next week with dry weather except the risk of a passing snow shower from a cold front Tuesday. Forecast details follow…
TODAY: Variably cloudy, limited sun. Highs 36-43. Wind W shifting to N 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 28-35. Wind NE up to 10 MPH.
SATURDAY: Cloudy. Rain arriving afternoon. Highs 40-47. Wind SE increasing to 10-20 MPH, strongest South Coast.
SATURDAY NIGHT: Cloudy. Rain likely, risk of thunder, rain tapering off overnight. Temperatures steady in the 40s. Wind SE 10-20 MPH early then variable 5-15 MPH becoming W around dawn.
SUNDAY: Variably cloudy. Chance of a rain shower. Temperatures steady in the 40s. Wind W 10-20 MPH, higher gusts.
SUNDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.
MONDAY: Mostly sunny. Highs 35-42. Wind W 5-15 MPH.
TUESDAY: Partly sunny. A snow shower possible. Highs 35-42. Wind W 10-20 MPH.

DAYS 6-10 (JANUARY 29-FEBRUARY 2)
Fair, chilly January 29. Watching the period from later January 30 to early February 2 for a potential storm that will likely have colder air to work with and would present the risk of wind and precipitation, including frozen.

DAYS 11-15 (FEBRUARY 3-7)
Fair, seasonably chilly weather starts and ends the period with another storm threat in between.

7:22AM

DAYS 1-5 (JANUARY 23-27)
High pressure hangs on with nice weather today then moves offshore as another high presses down from eastern Canada with a cold front dropping through the region north to south on Friday with some cloudiness but no precipitation. Low pressure then tracks northeastward and the strongest indications are now that a primary low will remain stronger for longer and its secondary low will be a little weaker and too far west to hold cold air, which is marginal anyway, in for the upcoming precipitation shield, which will also have a quicker timing than previously expected. So look for a rain event starting Saturday afternoon and ending by the early hours of Sunday. But we do need to watch some energy as cold air returns Sunday for possible snow showers. Right now it does not look like this would develop into steady snowfall. By Monday, high pressure brings fair weather and a seasonable chill. Forecast details follow…
TODAY: Sun and high clouds. Highs 40-47. Wind SW up to 10 MPH.
TONIGHT: Variably cloudy. Wind W up to 10 MPH.
FRIDAY: Variably cloudy, limited sun. Highs 36-43. Wind W shifting to N 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 28-35. Wind NE up to 10 MPH.
SATURDAY: Cloudy. Rain arriving afternoon. Highs 40-47. Wind SE increasing to 10-20 MPH, strongest South Coast.
SATURDAY NIGHT: Cloudy. Rain likely evening, ending overnight. Lows 35-42. Wind SE 10-20 MPH early, then variable up to 10 MPH.
SUNDAY: Variably cloudy. Chance of snow showers. Temperatures stead 35-42. Wind W increasing to 10-20 MPH.
SUNDAY NIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH.
MONDAY: Mostly sunny. Highs 35-42. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 28-FEBRUARY 1)
Quick disturbance may bring a snow shower January 28. Fair, seasonably cold January 29. Watching the January 30-February 1 period for possible storminess, but too soon for details.

DAYS 11-15 (FEBRUARY 2-6)
One storm system may be impacting the region to start the period and another one may arrive mid to late period. Too soon to determine precipitation type.

7:37AM

DAYS 1-5 (JANUARY 22-26)
An area of high pressure crests over the region today then moves slowly offshore as we head toward late week with continue fair weather. Temperatures will be more moderate than they were to start the week. Then low pressure makes a run at the region for the weekend, currently looking, track-wise, similar to the system of last weekend, but with less cold air to work with, which should result in more of a variety of precipitation over more of the region, however there still should be enough cold around so that significant snow is possible for at least a portion of southeastern New England. Details will continue to be fine-tuned as it gets closer.
Forecast details…
TODAY: Sunny. Highs 33-40. Wind variable up to 10 MPH.
TONIGHT: Clear. Lows 5-10 interior valleys, 10-17 elsewhere. Wind calm.
THURSDAY: Sunny. Highs 38-45. Wind S up to 10 MPH.
THURSDAY NIGHT: Clear. Lows 22-29. Wind S under 10 MPH.
FRIDAY: Increasing clouds. Highs 38-45. Wind variable up to 10 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 20-27. Wind variable up to 10 MPH.
SATURDAY: Filtered sunshine morning. Cloudy afternoon with rain/mix/snow possible by late-day. Highs 35-42. Wind N up to 10 MPH.
SATURDAY NIGHT & SUNDAY: Cloudy with rain/mix/snow likely. Temperatures in the 30s to lower 40s. Wind variable 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 27-31)
Fair and seasonably cold January 27-29 except a few snow showers possible from a passing disturbance January 28. Watching the last couple days of the month for possible approach and impact by the next storm system.

DAYS 11-15 (FEBRUARY 1-5)
Winter storm threat potentials February 1-2 weekend and February 4-5.

7:28AM

DAYS 1-5 (JANUARY 21-25)
High pressure holds control over our weather through Friday, with continued cold weather on the eastern side of the high today, followed by a temperature moderation midweek as the high moves overhead then offshore. By late week we will have a weak cold front return a little chillier air back to the region, and there will be plenty of polar cold in eastern Canada while arctic air is locked up further north. By the time we get to Saturday, high pressure north and low pressure approaching from the southwest puts us on watch for a winter weather event, but the precipitation type, arriving by later Saturday based on current timing, is in question due to the marginal cold air here. Much to figure out between now and then.
Forecast details…
TODAY: Mostly sunny. Highs 25-32. Wind NW 5-15 MPH, diminishing this afternoon.
TONIGHT: Partly cloudy. Lows 5-10 interior, 10-15 coast. Wind variable up to 10 MPH.
WEDNESDAY: Sunny. Highs 33-40. Wind variable up to 10 MPH.
WEDNESDAY NIGHT: Clear. Lows 5-10 interior valleys, 10-17 elsewhere. Wind calm.
THURSDAY: Sunny. Highs 38-45. Wind S up to 10 MPH.
THURSDAY NIGHT: Clear. Lows 22-29. Wind S under 10 MPH.
FRIDAY: Increasing clouds. Highs 38-45. Wind variable up to 10 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 20-27. Wind variable up to 10 MPH.
SATURDAY: Filtered sunshine morning. Cloudy afternoon with rain/mix/snow possible by late-day. Highs 35-42. Wind N up to 10 MPH.

DAYS 6-10 (JANUARY 26-30)
Low pressure will likely impact the region with rain/mix/snow January 26. Fair, colder January 27. Clipper low or frontal system brings a snow shower risk January 28 followed by fair and seasonably cold weather.

DAYS 11-15 (JANUARY 31-FEBRUARY 4)
Watching January 31-February 2 for possible winter storm threat with high pressure in eastern Canada and potential low pressure near or south of New England. Another storm threat is possible by the end of the period.

7:35AM

DAYS 1-5 (JANUARY 20-24)
A quiet 5-day period as high pressure approaches today then settles across the region Tuesday through midweek before shifting offshore Friday. We start out with wind and cold today between the approaching high and a departing offshore storm. The northwesterly air flow over the warmer water may bring a few snow showers to outer Cape Cod today. Tranquil weather is expected Tuesday through midweek as high pressure moves overhead. Cloudiness arrives Friday as the high shifts offshore and a warm front moves toward the region.
Forecast details…
TODAY: Clouds give way to sunshine except additional clouds and a risk of snow showers outer Cape Cod. Highs 22-29. Wind NW 10-20 MPH with higher gusts. Wind chill near to below 10 at times.
TONIGHT: Clear. Lows 8-15. Wind NW 10-20 MPH, higher gusts. Wind chill often below 0.
TUESDAY: Sunny morning. Partly sunny afternoon. Highs 26-33. Wind NW 5-15 MPH, diminishing late.
TUESDAY NIGHT: Clear. Lows 5-10 interior, 10-15 coast. Wind variable up to 10 MPH.
WEDNESDAY: Sunny. Highs 33-40. Wind variable up to 10 MPH.
WEDNESDAY NIGHT: Clear. Lows 5-10 interior valleys, 10-17 elsewhere. Wind calm.
THURSDAY: Sunny. Highs 38-45. Wind S up to 10 MPH.
THURSDAY NIGHT: Clear. Lows 22-29. Wind S under 10 MPH.
FRIDAY: Increasing clouds. Highs 38-45. Wind SE up to 10 MPH.

DAYS 6-10 (JANUARY 25-29)
January 25-26 weekend will likely be impacted by a low pressure area, track uncertain, with a risk of snow/mix/rain. Fair, cold January 27. Clipper type low brings snow shower risk January 28. Fair, cold January 29.

DAYS 11-15 (JANUARY 30-FEBRUARY 3)
Watching January 30-February 2 for possible winter storm threat with high pressure in eastern Canada and potential low pressure near or south of New England. Fair, colder to end period.

8:44AM

DAYS 1-5 (JANUARY 19-23)
A little tranquility this morning behind our light to moderate snow/mix event of last night. From reports, looks like under 3 inches of snow fell near the South Coast and generally 3-6 inches elsewhere. Here at Woods Hill I recorded exactly 4 inches of snow which ended with a quick burst of sleet in the 1AM hour this morning. So the quick mover is gone, and as it moves away, like several of its predecessors it will blow up in the Maritime Provinces of Canada and help deliver colder air to us starting later today and through MLK Jr Day on Monday. That newly delivered cold, though not deep arctic on origin, will keep it very mid winter feeling through Tuesday before a midweek moderation. All the while high pressure will be in control of the weather with a welcomed quiet period.
Forecast details…
TODAY: Sun and passing clouds. Highs 35-42. Wind W increasing to 10-20 MPH with higher gusts.
TONIGHT: Partly cloudy. A brief passing snow shower possible evening. Lows 10-17. Wind NW 10-20 MPH, higher gusts. Wind chill near 0.
MONDAY (MLK JR DAY): Sun and passing clouds. Isolated snow showers possible. Highs 24-31. Wind NW 10-20 MPH, higher gusts. Wind chill often 10 or under.
MONDAY NIGHT: Clear. Lows 5-12. Wind NW 10-20 MPH early, diminishing late.
TUESDAY: Sunny. Highs 25-32. Wind N 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 5-10 interior, 10-15 coast. Wind variable up to 10 MPH.
WEDNESDAY: Sunny. Highs 33-40. Wind variable up to 10 MPH.
WEDNESDAY NIGHT: Clear. Lows 5-10 interior valleys, 10-17 elsewhere. Wind calm.
THURSDAY: Sunny. Highs 38-45. Wind S up to 10 MPH.

DAYS 6-10 (JANUARY 24-28)
Clouds move in January 24 ahead of a warm front approaching but only a slight threat of some very light precipitation arriving. A low pressure system has to be watched for the January 25-26 weekend but at this point I am not sure of its path and strength. Leaning toward a track just northwest of New England, a quick warm-up for January 25, a quick period of rain showers, then a return to wind and chilly weather to end that weekend but the low track could easily end up further south, so this is a very low confidence forecast at this point. Fair, colder January 27. Clipper low pressure may bring light snow or snow showers to end the period.

DAYS 11-15 (JANUARY 29-FEBRUARY 2)
Starting out fair and chilly, and then we need to watch the pattern closely for the possibility of a winter precipitation event.

10:46AM

DAYS 1-5 (JANUARY 18-22)
Late update, short version. No big changes other than to round out the snow totals by adding a bit to southern areas as the colder scenario wins out, as was expected. A lesson in a storm track being through the Great Lakes and a weak secondary low coming right across the area does not always mean mostly rain. It’s very cold to start out, and by the time it warms up enough for solid rain, the precipitation will have departed. It’s all about the synoptic set-up, not so much what you see in a text book. So we get our moderate winter weather event mainly this evening, and it’s gone by Sunday, but more wind and mid winter cold follows it through Martin Luther King Jr. Day on Monday. And in fact it gets quite cold here as we get into Tuesday and Wednesday, but with dry weather under the influence of high pressure.
Forecast details…
TODAY: Increasing cloudiness. Highs 23-30. Wind variable under 10 MPH.
TONIGHT: Overcast. Snow of 3-6 inches from dusk to around midnight, except under 3 inches South Coast where mix/rain occurs for the second half of the precipitation. Brief mix may get into the I-90 and I-95 areas before the end. Temperatures rise into the 30s. Wind E-SE 10-20 MPH becoming variable overnight.
SUNDAY: Cloudy at dawn with patchy drizzle and freezing drizzle northern MA and southern NH with breaking clouds elsewhere. Variably cloudy balance of day with isolated snow showers. Highs 36-43. Wind variable 5-15 MPH morning, NW 15-25 MPH with higher gusts afternoon.
SUNDAY NIGHT: Partly cloudy. Isolated snow showers early. Lows 10-17. Wind NW 10-20 MPH, higher gusts. Wind chill near to below 0.
MONDAY (MLK JR DAY): Sun and passing clouds. Isolated snow showers possible. Highs 22-29. Wind NW 10-20 MPH, higher gusts. Wind chill often 10 or under.
MONDAY NIGHT: Clear. Lows 5-12. Wind NW 10-20 MPH early, diminishing late.
TUESDAY: Sunny. Highs 23-30. Wind N 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 5-10 interior, 10-15 coast. Wind variable up to 10 MPH.
WEDNESDAY: Sunny. Highs 25-32. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 23-27)
Fair, moderating temperatures January 23-24. Weakening low pressure system passes by January 25 with some cloudiness and possible light precipitation. High pressure rebuilds with fair weather later in the period, seasonably chilly but no arctic cold this time.

DAYS 11-15 (JANUARY 28-FEBRUARY 1)
Quick low pressure wave and cold front brings a snow shower risk January 28 followed by colder and dry weather January 29-30. Watching the end of the period for a possible winter storm threat.

7:21AM

DAYS 1-5 (JANUARY 17-21)
Mid winter cold but bright sun today as high pressure in eastern Canada influences the weather here in southeastern New England. And the cold air this high supplies will play a role in the weekend weather as low pressure tracks into the Great Lakes Saturday then down the St. Lawrence Valley Sunday. Many times this track would produce rain here but with plenty of cold air in place and due to the quick movement of the precipitation shield with the low, the bulk of what falls will be in the form of snow – not a big storm but significant enough to warrant shoveling and plowing for a good part of the region. This will occur from the end of the afternoon Saturday through Saturday night. Warm enough air will get involved for a flip to the rain South Coast to about I-90 and perhaps up along I-95 to the northeast, and a brief mix to the northwest, occurring as the precipitation is ending from west to east. This means that rainfall on top of any snow that falls will be limited, which will be good news since more cold air will be set to move back in as this system departs, becoming quite entrenched for the start of next week.
Forecast details…
TODAY: Sunny. Highs 18-25. Wind NW 15-25 mph, gusting over 30 MPH at times. Wind chill often below 10.
TONIGHT: Clear. Lows 5-12. Wind NW 5-15 MPH, gusting over 20 MPH at times. Wind chill often below 0.
SATURDAY: Increasing cloudiness. Highs 23-30. Wind variable under 10 MPH.
SATURDAY NIGHT: Overcast. Precipitation arriving early evening as snow west to east, turning to rain South Coast to I-90 belt and coastline and mixing with rain interior areas north of I-90 before ending pre-dawn. Snow accumulation 1-3 inches in areas that turn to rain, 3-5 inches in areas that mix with rain, with an isolated 6 inch amount possible higher elevations north central MA and/or southern NH.
Temperature rising into the 30s. Wind NE 5-15 MPH evening, E-SE 10-20 MPH overnight.
SUNDAY: Cloudy at dawn with patchy drizzle and freezing drizzle northern MA and southern NH with breaking clouds elsewhere. Variably cloudy balance of day with isolated snow showers. Highs 36-43. Wind variable 5-15 MPH morning, NW 15-25 MPH with higher gusts afternoon.
SUNDAY NIGHT: Partly cloudy. Isolated snow showers early. Lows 10-17. Wind NW 10-20 MPH, higher gusts. Wind chill near to below 0.
MONDAY (MLK JR DAY): Sun and passing clouds. Isolated snow showers possible. Highs 22-29. Wind NW 10-20 MPH, higher gusts. Wind chill often 10 or under.
MONDAY NIGHT: Clear. Lows 5-12. Wind NW 10-20 MPH early, diminishing late.
TUESDAY: Sunny. Highs 23-30. Wind N 5-15 MPH.

DAYS 6-10 (JANUARY 22-26)
High pressure dominates January 22-23 with a cold start then slight moderation in temperature. Weakening low pressure approaches and moves through, bringing the threat of some precipitation anytime in the January 24 to early January 26 time frame with temperatures not too far from normal.

DAYS 11-15 (JANUARY 27-31)
This period is a lower confidence outlook, but we’ll have to watch for a strung out area of low pressure to bring a precipitation threat the first couple days of the period, a break, then another storm threat later in the period.

7:39AM

DAYS 1-5 (JANUARY 16-20)
Low pressure departs and intensifies as it moves away via the Gulf of Maine and southeastern Canada today through tonight, and this will, combined with a large high pressure area moving across east central Canada, will cause plenty of wind and drag in cold air, returning the feel of mid winter to southeastern New England as we move through Friday and into the weekend, setting up a winter weather event as low pressure moves across the region mid weekend. There are not really any changes to the outlook on this system as discussed in yesterday’s blog. I’ll be leaning toward the lower sides of the preliminary snow amounts mentioned yesterday, not because there is the threat of a flip to rain after the precipitation arrives in the form of snow, but because the narrow width of the precipitation shield and the speed of its movement will simply prevent all that much from falling, even though the bulk of it will be in the form of snow, only changing toward its end from southwest to northeast. This system departs Sunday with another bout of windy, cold, drier weather lasting through MLK Jr. Day Monday.

DAYS 6-10 (JANUARY 21-25)
Slight change in the outlook as it looks less likely an ocean storm will be located close enough to the region for impact at mid period, and more likely a low pressure area will approach and impact the region around January 24-25 with snow/mix threat, but even this system may end up being very minor and have minimal impact. Before that, dry and very cold.

DAYS 11-15 (JANUARY 26-30)
Coldest weather eases somewhat. Additional storm threat with snow/mix/rain threat middle to end of period.
