DAYS 1-5 (FEBRUARY 5-9)

High pressure brings dry and cold weather through Friday with abundant sunshine anticipated today, but more limited sun Friday due to both an increasing in high and mid level cloudiness from the west with the approach of a trough and cold front, and lower clouds from the ocean in the coastal plain with a low level northeasterly air flow developing. After this, a complex process of frontal passage and upper level energy transfer from low pressure to our north to developing low pressure to our south and southeast takes place, the end result of which is a deepening ocean storm with an inverted trough swinging back through southeastern New England. This entire process takes place during the calendar day hours of Saturday, resulting in periods of snow, the finale of which is expected to be an inverted trough induced batch of moderate to heavy snow for a couple hours moving north to south across far eastern areas late Saturday afternoon into early Saturday night. The complex evolution results in an uneven expectation for snowfall amounts, which will be reflected in the detailed accumulation forecast that appears on the Saturday night portion of the forecast below. Following this event, in comes a shot of arctic air, along with wind, that will result in extremely cold wind chill readings but dry weather during Sunday. While the wind and cold ease slightly by Monday, it will remain fair and quite cold with arctic high pressure in control.

TODAY: Mostly sunny. Highs 25-32. Wind N up to 10 MPH.

TONIGHT: Mostly clear. Lows 15-22. Wind variable up to 10 MPH.

FRIDAY: Increasing clouds. Highs 23-30. Wind N to NE 5-15 MPH.

FRIDAY NIGHT: Cloudy. Chance of snow overnight. Lows 13-20. Wind NE 5-15 MPH.

SATURDAY: Cloudy. Periods of snow. Heavier snow showers likely Cape Ann to MA South Shore late-day. Highs 20-27. Wind NE to N 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy evening with lingering snow showers early, including heavier snow showers likely MA South Shore to Cape Cod early. Total snowfall accumulation for the event expected to be 1 to 3 inches in much of the area, but 2 to 4 inches in a few higher elevations of North Central MA and 3 to 6 inches from Cape Ann to the MA South Shore and possibly Cape Cod. Clearing overnight. Lows 0-7. Wind N to NW increasing to 15-25 MPH creating blowing snow and wind chill readings below to well below zero.

SUNDAY: Sunny. Highs 10-17. Wind NW 15-25 MPH. Wind chill often below zero.

SUNDAY NIGHT: Clear. Lows -5 +2 except 0-7 Cape Cod and some urban centers. Wind NW diminishing to 5-15 MPH.

MONDAY: Sunny. Highs 17-24. Wind NW 5-15 MPH.

DAYS 6-10 (FEBRUARY 10-14)

Fair with temperature moderation early period. Unsettled weather potential increases later period.

DAYS 11-15 (FEBRUARY 15-19)

Up-and-down temperature pattern with one or two more unsettled weather potentials but no major storms expected.

DAYS 1-5 (FEBRUARY 4-8)

Some quick changes will take place during this 5-day period but without having to deal with any major storms. We will have to deal with a potent shot of arctic air before we finish the weekend, however. But back to today first, we have a disturbance passing south of our region and some low and mid level moisture associated with it passing through with a fair amount of clouds the first part of the day. A few snow flurries can occur under these clouds, but if you see any, then will have no impact on your travel or plans. A weak area of high pressure moves in later today through Thursday and into Friday with fair weather. Late Friday, a frontal boundary approaches from the west while a stronger ocean storm stays well offshore and scoots out to sea. With an upper trough in place, the initial low pressure, separate from the ocean storm, parenting the cold front will be moving by to our north and redeveloping a little closer-by, near NY State, slowing and bending the frontal boundary, and then redeveloping again during Saturday offshore to our southeast. This system is also destined to become a strong ocean storm, but will do so far enough away from our region so that we will only see some snowfall from the transfer of the first redeveloped low to the offshore storm-to-be. This means the snowfall, which occurs from late Friday night into Saturday, will be relatively minor. What the offshore storm will do is help pull in the aforementioned arctic air mass for Saturday night and Sunday, with well below normal temperatures and gusty winds making it feel even colder to finish off the weekend.

TODAY: Lots of clouds and a possible snow flurry until mid morning, then a mix of sunshine and clouds. Highs 26-33. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Lows 10-17. Wind variable up to 10 MPH.

THURSDAY: Mostly sunny. Highs 23-30. Wind N up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 15-22. Wind variable up to 10 MPH.

FRIDAY: Increasing clouds. Highs 23-30. Wind variable up to 10 MPH.

FRIDAY NIGHT: Cloudy. Chance of snow overnight. Lows 13-20. Wind variable 5-15 MPH.

SATURDAY: Mostly cloudy. Periods of snow with expected accumulation of a coating to 2 inches. Highs 20-27. Wind variable 5-15 MPH.

SATURDAY NIGHT: A possible snow squall early, otherwise clearing. Lows 0-7. Wind NW 15-25 MPH, higher gusts. Wind chill below zero.

SUNDAY: Sunny. Highs 10-17. Wind NW 15-25 MPH. Wind chill often below zero.

DAYS 6-10 (FEBRUARY 9-13)

Fair weather and moderating temperatures February 9-11. Low pressure area from the west brings unsettled weather later in the period.

DAYS 11-15 (FEBRUARY 14-18)

Up-and-down temperature pattern – near to below normal for the period, with a couple unsettled periods but no major storms expected.

DAYS 1-5 (FEBRUARY 3-7)

Cold, generally dry weather continues through midweek, with just one disturbance going by late tonight and early tomorrow causing possible snow showers – basically a no-impact event, other than to reinforce the cold a little, but still not to the level of recent cold. However, another system passing by that can bring some light snow Friday night and early Saturday will deliver an arctic air mass, quite evident during the day Saturday when the temperatures don’t really go up, but the wind does. More next discussion.

TODAY: Partly cloudy. Highs 26-33. Wind W up to 10 MPH.

TONIGHT: Increasing clouds. A snow shower possible mostly south of I-90 overnight. Lows 12-19. Wind SW up to 10 MPH.

DAYS 6-10 (FEBRUARY 8-12)

Dry, very cold February 8, then a moderation but still below normal with fair weather until late period when there is a chance of unsettled weather.

DAYS 11-15 (FEBRUARY 13-17)

Up-and-down temperature pattern – near to below normal for the period, with a couple unsettled periods but no major storms expected.

DAYS 1-5 (FEBRUARY 2-6)

Just had a zoom coffee with Punxutawey Phil and now he’s going out to meet his public while I write today’s blog. We agreed that I’ll handle the next 15 days and he can handle the next 4 to 6 weeks. 😉 Let’s get to it! The story is cold this week, but not quite as cold as last week during this 5-day period as we are in a dry pattern through midweek. A disturbance passes by Tuesday night and early Wednesday and may produce snow showers south of I-90 but for the most part this system looks like a miss. We’ll look to the west for a more formidable clipper-style low pressure area heading our way by Friday, bringing a chance of snow or snow showers. A little more about this chance as we head through the next few days.

TODAY: Mostly sunny to partly cloudy. Highs 25-32. Wind NW 5-15 MPH.

TONIGHT: Mostly clear to partly cloudy. Lows 3-10. Wind diminishes to calm.

TUESDAY: Partly cloudy. Highs 26-33. Wind W up to 10 MPH.

TUESDAY NIGHT: Increasing clouds. A snow shower possible south of I-90 overnight. Lows 12-19. Wind SW up to 10 MPH.

WEDNESDAY: Variably cloudy. A snow shower possible south of I-90 early. Highs 25-32. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 10-17. Wind variable up to 10 MPH.

THURSDAY: Partly cloudy. Highs 23-30. Wind N up to 10 MPH.

THURSDAY NIGHT: Clouding up. Lows 15-22. Wind variable up to 10 MPH.

FRIDAY: Cloudy with a chance of snow. Highs 23-30. Wind variable 5-15 MPH.

DAYS 6-10 (FEBRUARY 7-11)

Watching the potential for a serious cold outbreak on the February 7-8 weekend, then a slight relaxing of the cold thereafter with dry weather followed by the potential for unsettled weather by the end of the period.

DAYS 11-15 (FEBRUARY 12-16)

Some up-and-down temperatures but generally below normal with a couple threats for snow showers from passing disturbances.

P.S. – I just got a message from Phil. Shadow seen – six more weeks of winter ahead! Enjoyyyyyyyy!

DAYS 1-5 (FEBRUARY 1-5)

A powerful ocean storm passes by well to our southeast today. On the northwestern periphery of its circulation we see some ocean-effect snow from the MA South Shore to South Coast, and some synoptic snow from the storm itself over Cape Cod for a few hours, all resulting in a general 1-3 inch snowfall, which drops off quickly to nothing at all as you head west of the Route 24 area south of Boston. The city of Boston and Cape Ann MA can see a few ocean-effect flurries, but with no more than a dusting to 1 inch (especially Cape Ann). Any snow that accumulates will be hard to measure as a gusty northeasterly wind will blow it around. The storm pulls away tonight and our pattern from here is chilly and generally dry heading through the middle of this coming week. While we’re not in as deep a cold air mass as previously, it does stay generally colder than normal through Thursday. A disturbance passing by may produce snow showers or a period of light snow sometime on Wednesday, but this does not look like a significant system to contend with.

TODAY: Mostly cloudy. Snow showers likely MA South Shore to MA South Coast including Cape Cod, with a period of steadier snow midday-afternoon Cape Cod, with general snow accumulation of 1 to 3 inches. Occasional snow showers Cape Ann MA to Boston with under 1 inch. Highs 18-25. Wind N to NE 10-20 MPH inland and 15-30 MPH coast with higher gusts, especially Cape Cod. Minor to pockets of moderate coastal flooding around the time of high tide.

TONIGHT: Clearing. Lows 9-16. Wind N to NW 10-20 MPH, higher gusts, especially coastal areas.

MONDAY: Mostly sunny to partly cloudy. Highs 25-32. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 11-18. Wind NW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 26-33. Wind W up to 10 MPH.

TUESDAY NIGHT: Increasing clouds. Lows 12-19. Wind SW up to 10 MPH.

WEDNESDAY: Variably cloudy. Chance of snow showers, mostly southern areas and mostly morning. Highs 25-32. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 10-17. Wind variable up to 10 MPH.

THURSDAY: Partly cloudy. Highs 23-30. Wind N up to 10 MPH.

DAYS 6-10 (FEBRUARY 6-10)

Passing low pressure brings the chance of snow February 6-7, but not looking like a major storm system. Fair weather follows. Temperatures below normal.

DAYS 11-15 (FEBRUARY 11-15)

Some up-and-down temperatures but generally below normal with a couple threats for snow showers from passing disturbances.

DAYS 1-5 (JANUARY 31 – FEBRUARY 4)

You’ll recall yesterday the comparison to yesterday morning’s low temperatures and the expected low for this morning being different due to the difference between a gusty wind and nearly calm conditions. Well, winds are calm in many areas this morning, others seeing a light northwesterly breeze 10 MPH or under. Temperatures have responded accordingly, but there is quite a range also to be noted as the sun comes up. Norwood MA is our area cold spot, having been calm all night, and fallen to a low temp of -12, while at Provincetown MA on the tip of Cape Cod, a northwest breeze of 10 MPH coming across milder ocean water has their temp sitting at +13, along with a few ocean-effect snow flurries in the area. Boston’s Logan airport sits at +8 while most of its suburbs and outskirts sit between 0 and -10 as of sunrise. This is the type of early morning you can throw hot water to “make a cloud”, but if you do that, use caution! Today’s weather will be cold and fairly tranquil to wrap up the month of January, and the sun will start to fade behind increasing high cloudiness later as the much-talked-about storm organizes well to our south. This storm is going to intensify rapidly, i.e., undergo “bombogenesis”, and after bringing a significant snowfall to the Carolinas and Virginia, will spare the Mid Atlantic and most of the Northeast, only grazing far southeastern New England with the edge of its synoptic snow shield Sunday, while the circulation around it does help initiate some ocean-effect snow on the MA South Shore to Cape Cod late tonight into Sunday. This will account for most of the snowfall accumulation we see, with a little synoptic addition most notable on Outer Cape Cod and Nantucket. Once you get to about Boston and all points west, the most you see are a few flakes of snow with much of this region only being under the storm’s cloud canopy but seeing no snowfall at all. A few hundred miles further west and north with this storm track, and we’d be looking at a storm potentially the magnitude of last week’s except with much stronger wind, along with significant coastal flooding. As is, even with the far out to sea track, the circulation around the storm is enough to lead to some minor to borderline moderate coastal flooding near high tide times on Sunday in areas most prone to it. The monster storm goes by and heads for a Nova Scotia walloping Monday as we see dry, windy, and chilly weather for Groundhog Day, and continued fair and chilly weather into the middle of next week. This time it won’t be be quite as cold as we have seen recently, though it will still be running somewhat below normal for the early part of February.

TODAY: Sun and high clouds. Highs 17-24. Wind N 5-15 MPH.

TONIGHT: Clouding up. Snow showers MA South Shore to Cape Cod. Lows 8-15. Wind N to NE 5-15 MPH.

SUNDAY: Cloudy. Snow likely Cape Cod and MA South Shore to southeastern RI with most areas seeing 1-3 inches, but a couple areas of 3-6 inches possible MA South Shore and especially Outer Cape Cod and Nantucket. Occasional light snow with under 1 inch Boston to Providence. Snow threat ends by late-day. Highs 18-25. Wind N to NE 15-25 MPH except 25-35 MPH with higher gusts southeastern MA, especially Cape Cod / Islands.

SUNDAY NIGHT: Clearing. Lows 9-16. Wind N to NW 10-20 MPH, higher gusts, especially coastal areas.

MONDAY: Mostly sunny to partly cloudy. Highs 25-32. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 11-18. Wind NW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 26-33. Wind W up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 12-19. Wind SW up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 25-32. Wind W 5-15 MPH.

DAYS 6-10 (FEBRUARY 5-9)

Watching the period late February 5 to early February 7 for a snow chance but too soon for details. Fair weather follows. Temperatures below normal.

DAYS 11-15 (FEBRUARY 10-14)

Some up-and-down temperatures but generally below normal with a couple threats for snow showers from passing disturbances.

DAYS 1-5 (JANUARY 30 – FEBRUARY 3)

Our cold pattern rolls on, and the the final 2 mornings of the first month of 2026 present an opportunity for a weather lesson – a comparison between today’s low temperatures and tomorrow’s low temperatures, noting the difference even though we’re in the same air mass. Why is that going to happen? The answer is simple. Wind today. Lack of wind tomorrow. This morning’s low temperatures are in the single digits to lower teens across the entire WHW forecast area, rather uniform due to a busy northwesterly wind mixing the air adequately enough so that we don’t see that difference between coast and inland, lower and higher elevation. Tomorrow morning, the air will be calm, so we will see those differences, when even though the air mass has not changed, there can be large differences in low temperature between an urban area or a town right at the water’s edge, and an inland valley location. Prepare for a pop quiz at some point! 😉 … During this time we’ll see dry weather, with lots of sun both today and Saturday, but some filtering of that sun Saturday due to increasing high clouds ahead of our next storm threat. This threat exists late Saturday night and Sunday, but looks rather different than our previous big hit, as we will be side-swiped by a large ocean storm. It does appear that it will pass close enough to bring some accumulating snow to southeastern MA and as far west as the I-95 belt as well, with a drop off to not much / nothing west of there. There are still possibilities of a slight track variation in that storm enough to shift it all further east and offshore, and a lesser but not zero chance of a westward shift expanding the snow area and potential amounts, though the latter is less likely than the former. Beyond that, we return to fair weather and not quite as cold weather for the beginning of next week.

TODAY: Sunny. Highs 15-22. Wind NW 10-20 MPH, higher gusts. Wind chill below 10.

TONIGHT: Clear. Lows -5 to +2, colder pockets in valleys. Wind NW to N diminishing to under 10 MPH.

SATURDAY: Sun and high clouds. Highs 17-24. Wind N 5-15 MPH.

SATURDAY NIGHT: Clouding up. Lows 7-14. Wind N to NE 5-15 MPH.

SUNDAY: Cloudy. Snow likely coast / southeastern areas. Chance of snow elsewhere. Potential snow accumulation of 4+ inches Cape Cod / Islands, 2+ inches MA South Shore to southeastern RI, 1+ inch I-95 belt, and less than 1 inch west of the I-95 belt. Highs 18-25. Wind N to NE 15-25 MPH except 25-35 MPH with higher gusts southeastern MA, especially Cape Cod / Islands.

SUNDAY NIGHT: Snow ends, sky clears. Lows 10-17. Wind N to NW 10-20 MPH, higher gusts especially coastal areas.

MONDAY: Mostly sunny to partly cloudy. Highs 25-32. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear to partly cloudy. Lows 11-18. Wind NW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 26-33. Wind W up to 10 MPH.

DAYS 6-10 (FEBRUARY 4-8)

Watching for a winter weather threat around February 5 to early February 6, and another minor threat over the February 7-8 weekend. Temperatures near to below normal.

DAYS 11-15 (FEBRUARY 9-13)

Temperatures mostly below normal but with more variation and a couple chances of snow showers as cold air is reinforced, but overall a quieter pattern in terms of storm threats.

DAYS 1-5 (JANUARY 29 – FEBRUARY 2)

The big chill remains with us as we wrap up January over the next few days. The coldest of the final 3 days of the month will be Friday, and along with a gusty wind, it will feel even colder. Today we see a band of ocean-effect snow showers that can bring some minor accumulation to Outer Cape Cod while the rest of us can see a passing snow shower with a reinforcing arctic boundary passing by late in the day or early this evening. Dry conditions will persist Friday and Saturday, though like last Saturday, this one will also feature an increase in high cloudiness ahead of a storm system developing to our south. As far as the storm and its threat to us, the evolution and track of this one will be different from the previous one. Low pressure deepens and matures fairly rapidly in the ocean south of New England after giving significant snow to parts of the Southeast and southern Mid Atlantic. While it looks like this storm system’s low center is going to pass well southeast of our region, its large circulation is certainly going to have some impact in terms of wind and some snowfall. The strongest winds will most definitely occur over Cape Cod. The snowfall is still something I am in the process of figuring out and fine-tuning, and that will take a couple more days. As it stands now, the best chance of a significant snowfall on Sunday will be over southeastern MA including Cape Cod and the Islands, with chances dropping off fairly significant as you head northwest across the region. Behind this system comes dry weather for Monday, and this time the air mass will not be quite as cold as what we are enduring this week.

TODAY: Clouds and occasional snow showers Outer Cape Cod with up to 1 or 2 inches of accumulation. Sunny to partly cloudy elsewhere with a chance of snow showers west to east by late in the afternoon. Highs 16-23. Wind NW 10-20 MPH.

TONIGHT: Partly cloudy with a chance of snow showers early, then clearing. Lows -1 to +6. Wind NW 10-20 MPH, higher gusts. Wind chill below zero.

FRIDAY: Sunny. Highs 15-22. Wind NW 10-20 MPH, higher gusts. Wind chill below 10.

FRIDAY NIGHT: Clear. Lows -5 to +2, colder pockets in valleys. Wind NW to N diminishing to under 10 MPH.

SATURDAY: Sun and high clouds. Highs 17-24. Wind N 5-15 MPH.

SATURDAY NIGHT: Clouding up. Lows 7-14. Wind N to NE 5-15 MPH.

SUNDAY: Cloudy. Snow likely coast / southeastern areas. Chance of snow elsewhere. Highs 18-25. Wind N to NE 15-25 MPH except 25-35 MPH with higher gusts southeastern MA, especially Cape Cod / Islands.

SUNDAY NIGHT: Snow ends, sky clears. Lows 10-17. Wind N to NW 10-20 MPH, higher gusts especially coastal areas.

MONDAY: Mostly sunny to partly cloudy. Highs 25-32. Wind NW 5-15 MPH.

DAYS 6-10 (FEBRUARY 3-7)

Temperatures remain below normal but not quite to the current level of cold. Watching for a winter weather threat about February 5 to early February 6, preceded by and followed by fair weather.

DAYS 11-15 (FEBRUARY 8-12)

Temperatures below normal but with more variation and a couple chances of snow showers as cold air is reinforced, but overall a quieter pattern in terms of storm threats.

DAYS 1-5 (JANUARY 28 – FEBRUARY 1)

A very cold pattern rolls on into the coming weekend to end January. It’s a dry one for now as well, between our last winter storm and an upcoming threat, with just a chance of snow showers from a passing disturbance from late today into tonight and a few ocean-effect snow showers possible on Cape Cod Thursday. Like last weekend, we’ll see high clouds spreading into the region by Saturday ahead of the next winter weather threat, which stems from a developing ocean storm well south of New England. This system is destined to take a northeastward track, and I lean toward a pass well to the southeast of here, but with a large enough system that we get into its envelope of gusty wind and probably at least part of the region experiences its snow area on Sunday. This configuration would bring the greatest chance of accumulating snow the further east and southeast you are in our region, but it’s far too soon to say just how much of an impact it will have and how far west the snow shield would extend. Stay tuned.

TODAY: Partly sunny. Chance of snow showers late-day. Highs 17-24. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Chance of snow showers early. Lows 4-11. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny except partly cloudy with a chance of snow shower Outer Cape Cod. Highs 16-23. Wind NW 10-20 MPH.

THURSDAY NIGHT: Clear. Lows -3 to +4. Wind NW under 10 MPH.

FRIDAY: Sunny. Highs 15-22. Wind NW under 10 MPH.

FRIDAY NIGHT: Clear. Lows -5 to +2. Wind N under 10 MPH.

SATURDAY: Sun and high clouds. Highs 17-24. Wind N 5-15 MPH.

SATURDAY NIGHT: Clouding up. Lows 7-14. Wind N to NE 5-15 MPH.

SUNDAY: Cloudy. Chance of snow. Highs 18-25. Wind NE 15-25 MPH, strongest coast, with higher gusts.

DAYS 6-10 (FEBRUARY 2-6)

Snow chance around February 5 to early February 6, preceded by dry and cold weather.

DAYS 11-15 (FEBRUARY 7-11)

Temperatures below normal but with more variation and a couple chances of snow showers as cold air is reinforced, but overall a quieter pattern in terms of storm threats.

DAYS 1-5 (JANUARY 27-31)

With deep snow cover and frequently reinforced cold from Canada, it’s the classic midwinter feel for the final 5 days of January. We’ll be a dry pattern for a while in the wake of our recent winter storm, with just a few snow flurries from time to time from disturbances passing through from the northwest. As we get to the weekend, we’ll be eyeing a developing storm to our south, which will spread increasing high cloudiness into our region on Saturday and bring the chance of snow by Saturday night, but at day 5 there is uncertainty with timing and track of that system, to be brought into more focus as the week goes on.

TODAY: Partly cloudy. Slight chance of a snow flurry this afternoon. Highs 19-26. Wind NW 10-20 MPH.

TONIGHT: Lots of clouds with a few snow showers early, then partly cloudy. Lows 0-7. Wind NW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of snow showers. Highs 17-24. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 4-11. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 16-23. Wind NW 10-20 MPH.

THURSDAY NIGHT: Clear. Lows -3 to +4. Wind NW under 10 MPH.

FRIDAY: Sunny. Highs 15-22. Wind NW under 10 MPH.

FRIDAY NIGHT: Clear. Lows -5 to +2. Wind N under 10 MPH.

SATURDAY: Sunshine followed by increasing clouds. Chance of snow at night. Highs 17-24. Wind N to NE 5-15 MPH.

DAYS 6-10 (FEBRUARY 1-5)

Storm potentials February 1 and 5, with dry and cold weather in between.

DAYS 11-15 (FEBRUARY 6-10)

Quieter but continued cold pattern anticipated during this period with a couple minor systems bringing snow shower chances.

DAYS 1-5 (JANUARY 26-30)

A major winter storm dumped significant snow on our region Sunday from mid morning to late at night, at which time much of the region saw a shut-down of accumulating snow for a while due to a dry slot working in from the west. As of 3:30 a.m., there are ocean-effect snow showers ongoing along much of the MA coast, with some of them working a little further inland from Metro Boston to the Cape Cod Canal. During the heavier precipitation, some sleet worked into the South Coast region as was expected, and pockets of sleet mixing with the snow made it up into parts of Plymouth County. A coastal front was present from just west of Boston up into Essex County MA and near the NH Seacoast to the north, and down into southeastern MA inland from the South Shore to the south, but early this morning it is already pushing to the southeast and the colder air is returning to places that warmed up (relatively speaking) into the 20s (some lower 30s Cape Cod / Islands), while temperatures struggled out of the single digits into the teens during most of the day and evening over the large area to the west of this coastal front – a very cold winter storm for much of the region indeed, unlike what we see in most of our winter events. Today, we’ll still be dealing with the storm system as the primary low pressure area still has to pass by to our south and we’ll be in its circulation, along with the upper level low driving the entire system. Ocean-effect snow can go on for a good portion of the day, and will focus mostly on the South Shore where up to several additional inches of snow can accumulate. There is also some wrap-around moisture on the back side of our low pressure area that has to move through much of the region later today into this evening before moving out to the east, and this can also produce up to a couple additional inches of accumulation, so my general thought process on this is 1 to 3 total additional inches of accumulation through this evening in the majority of the region, with up to 1 inch additional nearer the South Coast. We finally bid this system goodbye tonight, and then settle into a cold and dry pattern through Friday, with just a few snow showers potentially occurring on Wednesday as a disturbance moves through.

TODAY: Cloudy. Periods of snow. Additional accumulation up to 1 inch South Coast, 1 to 3 inches elsewhere. Highs 18-25. Wind N to NW 10-20 MPH.

TONIGHT: Mostly to partly cloudy. A lingering snow flurry possible. Lows 10-17. Wind NW 10-20 MPH.

TUESDAY: Partly cloudy. Highs 19-26. Wind NW 10-20 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 0-7. Wind NW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of snow showers. Highs 17-24. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 4-11. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 16-23. Wind NW 10-20 MPH.

THURSDAY NIGHT: Clear. Lows -3 to +4. Wind NW under 10 MPH.

FRIDAY: Sunny. Highs 15-22. Wind NW under 10 MPH.

DAYS 6-10 (JANUARY 31 – FEBRUARY 4)

Storm potential exists in the January 31 to February 2 time frame. Fair weather follows that threat. Temperatures below to much below normal.

DAYS 11-15 (FEBRUARY 5-9)

Another potential winter weather threat around February 5-6. Quieter pattern develops thereafter but temperature remain below normal.

DAYS 1-5 (JANUARY 25-29)

Major winter storm incoming. This one is not going to be one that produces big wind and coastal flooding issues. It’s a “mostly” snow event. As previously mentioned there is a decent shot at a swath of sleet along the South Coast, possibly as far north as Plymouth MA briefly, and if that scenario plays out the sleet can even go to rain on Nantucket. That part of the forecast really has not changed going into it. Timing is similar with snow overspreading the region from southwest to northeast late morning to early afternoon, peaking with highest rate of accumulation from the end of the afternoon to around midnight. It’s in this later evening time frame that the sleet potential would be realized to the south. After this, at least a partial dry slot will put a limit on precipitation to the south while the snow intensity diminishes to the north. But as elongated and redeveloping low pressure passes south of New England, probably just inside 40N/70W, it is going to take until Monday evening for the precipitation to completely taper off. The Monday portion of the storm will be somewhat complex in that any non-snow to the south will go back to snow, and there will be some features on the back side of the storm, and the wrap-around moisture behind the remains of the original low pressure area, all to cause additional episodes of snow. While the vast majority of the snowfall accumulation occurs this evening, there can still be additional accumulation of varying rates until the entire thing wraps up, and this is what will be taken into account for the updated snowfall total forecast, which is as follows: 12-18 inches in general regionwide, with the following potential exceptions – the first being an area of 8-12 inches where sleet is involved, and bands or splotches of 18-24 inches that are west of a coastal front feature that probably sets up near or east of I-95, as well as with the help of some enhancement from Atlantic moisture being transported in by the northeast wind, with these higher amounts most likely to occur in southeastern NH and northeastern MA, but also not impossible in other locations. Behind this system comes some solid winter cold but with mostly dry weather Tuesday through Thursday. There is a disturbance to pass by that may cause a few snow showers in the region during Wednesday.

TODAY: Overcast. Snow arrives southwest to northeast between late morning and early afternoon. Temperatures slowly rise to 18-25. Wind N to NE 5-15 MPH except 15-25 MPH Cape Cod by late-day.

TONIGHT: Overcast. Snow, heavy at times through midnight, tapering off in intensity overnight. Snow may mix with or change to sleet near the South Coast especially Cape Cod and a slight chance of a period of rain at Nantucket. Temperatures steady 18-25 but can rise to 26-33 South Coast / Cape Cod and potentially as far north as the MA South Shore. Wind NE 15-25 MPH Cape Cod / Islands, NE to N 5-15 MPH elsewhere.

MONDAY: Cloudy. Periods of snow – with sleet changing back to snow South Coast. (See discussion for total accumulation expectation.) Temperatures remain generally steady or fall slightly. Wind N to NW 10-20 MPH, a few higher gusts.

MONDAY NIGHT: Partly cloudy. A lingering snow flurry possible. Lows 12-18. Wind NW 10-20 MPH.

TUESDAY: Partly cloudy. Highs 21-28. Wind NW 10-20 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 5-12. Wind NW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of snow showers. Highs 22-29. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 4-11. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 20-27. Wind NW 10-20 MPH.

DAYS 6-10 (JANUARY 30 – FEBRUARY 3)

Storm potential exists in the January 31 to February 2 time frame and will keep an eye on that, otherwise continued below normal temperatures with dry weather to start and to end the period.

DAYS 11-15 (FEBRUARY 4-8)

Another potential winter weather threat around February 5-6. Quieter pattern develops thereafter but temperature remain below normal.

DAYS 1-5 (JANUARY 24-28)

An arctic cold front went through our region last night. Some you may have heard the wind gusts in the 35 to 45 MPH range. Some of you may, mainly northwest of Boston, saw a snow shower prior to midnight (I did). If you step outside this morning or any time today you will feel the deep chill of air delivered from far north of our area and it will be accompanied by wind, making it feel even colder during the day today. As the wind relaxes we’ll be in for a frigid night, but high clouds that start to filter the sunshine today will thicken up tonight ahead of an approaching winter storm. This system is a low pressure area elongating and redeveloping to our south, taking a track close to and possibly just north of the 40N/70W “benchmark” Sunday night into Monday, with the remains of the primary low following it up Monday. Result: An extended bout of precipitation, falling as snow across a great majority of the region. Complication: The track of the surface low allows some warmer air to intrude aloft, and as of early this morning a couple of short range models disagree on the degree of warming aloft, and resultant mix with sleet (and even potential change to rain briefly). One brings sleet to the South Coast / Cape Cod, but that’s the extent of it. The other brings the sleet area as far north as about Plymouth and more extensively along the South Coast, and a period of liquid rain to Cape Cod and the Islands. Right now I’m leaning to a compromise between the two solutions, with sleet more than just right on the South Coast, but not quite to Plymouth, and any rain at all being confined to Nantucket for a brief period of time. The other aspect of the storm to consider is a probable coastal front along near the eastern coastline, and where this sets up results in a little snowfall enhancement just to its west and slightly higher water content snow to its east. This may end up as far west as the I-95 belt, but is more likely to run from near Cape Ann to Boston to the MA South Shore or just inland from there, to west of the Cape Cod Canal. I’ll watch for that. During Monday, the passage of the back end of the low pressure area results in a wind shift and colder air anyway. Another wild card is a potential mid level slot of dry air that would cut some of the precipitation off south of I-90 and lessen amounts somewhat. But these areas would see additional snow showers on Monday. Obviously, with not much time to go, there are still some aspects of this short-term forecast to fine-tune. Behind this system comes more cold weather, though not as cold as our current air mass. Fair weather is expected Tuesday and a disturbance may bring a few snow showers to the region on Wednesday.

TODAY: Sun becomes filtered through increasing high clouds. Highs 12-19. Wind WNW 5-15 MPH, higher gusts. Wind chill below 10 at times.

TONIGHT: Increasing clouds. Lows 3-10. Wind N 5-15 MPH, diminishing.

SUNDAY: Overcast. Snow arrives southwest to northeast between mid morning and early afternoon. Temperatures slowly rise to 18-25. Wind N to NE 5-15 MPH except 15-25 MPH Cape Cod by late-day.

SUNDAY NIGHT: Overcast. Snow, heavy at times through midnight, tapering off in intensity overnight. Snow may mix with or change to sleet near the South Coast especially Cape Cod and a slight chance of a period of rain at Nantucket. Temperatures steady 18-25 but can rise to 26-33 South Coast / Cape Cod and potentially as far north as the MA South Shore. Wind NE 15-25 MPH Cape Cod / Islands, NE to N 5-15 MPH elsewhere.

MONDAY: Mostly cloudy. Lingering snow or flurries. Total storm accumulation expectation is 10 to 16 inches, but pockets of 16 to 22 inches are likely, and areas of under 10 inches are possible mainly Cape Cod / Islands, pending the impact of potential sleet (and rain that would be most likely on Nantucket). Temperatures remain generally steady or fall slightly. Wind N to NW 10-20 MPH, a few higher gusts.

MONDAY NIGHT: Partly cloudy. A lingering snow flurry possible. Lows 12-18. Wind NW 10-20 MPH.

TUESDAY: Partly cloudy. Highs 22-29. Wind NW 10-20 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 8-15. Wind NW 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of snow showers. Highs 23-30. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 29 – FEBRUARY 2)

Watching for the next potential storm in the January 31 to February 2 time frame. Temperatures below normal.

DAYS 11-15 (FEBRUARY 3-7)

Another potential winter weather threat around February 5 in a still active and cold weather pattern.

DAYS 1-5 (JANUARY 23-27)

Cold front #1 went by last night and will knock us back about 10 degrees off yesterday’s relatively mild high temps. An arctic cold front will move through by this evening and knock double that amount and even a bit more off our high temp expectations for Saturday – the coldest day of the winter so far. Other than the potential for a snow shower or squall with the passage of the arctic boundary, we’ll have dry weather through Saturday, but more wind, which leads to especially low wind chill values on Saturday before winds ease up later in the day. We’ll have a mix of sun and “mostly” fair weather clouds today, other than the ones that would produce the snow showers later. Saturday we’ll see sun eventually filtered by high clouds in advance of the winter storm that is going to impact our region Sunday into Monday. Since my last update, I’ve been watching guidance trends on this system, and have noted a slight northward trend still, enough to introduce the chance of some sleet mixing into the South Coast region during the second half of the storm and a little mid level dry slot cutting off or diminishing the precipitation a few hours earlier than a track slightly further south. So far this only has a fairly minor impact on the expectations for snowfall, but is still obviously worth monitoring as we continue to get closer to the event. I still expect elongated low pressure to pass relatively close to the “benchmark” (40N/70W) to our south Sunday night and early Monday. As it moves away, lingering snow or snow showers can last through a good portion of Monday, but the bulk of the snowfall accumulation should occur between early evening the very early morning hours of Monday, based on current timing. Post-storm, we can expect a blustery, cold, but dry day on Tuesday in a northwesterly air flow between departing low pressure and approaching high pressure.

TODAY: Partly cloudy. A late-day snow shower or snow squall possible. Highs 30-37. Wind W 10-20 MPH, gusts 25-35 MPH.

TONIGHT: Partly cloudy with a potential snow shower or snow squall early, then clear. Lows 2-9. Wind WNW 15-25 MPH, higher gusts. Wind chills below zero.

SATURDAY: Sun and high clouds. Highs 13-20. Wind WNW 10-20 MPH, higher gusts. Wind chills below 10.

SATURDAY NIGHT: Increasing clouds. Lows 3-10. Wind N 5-15 MPH, diminishing.

SUNDAY: Overcast. Snow arrives southwest to northeast between mid morning and early afternoon. Temperatures slowly rise to 18-25. Wind N to NE 5-15 MPH except 15-25 MPH Cape Cod by late-day.

SUNDAY NIGHT: Overcast. Snow, heavy at times through midnight, tapering off in intensity overnight. Snow may mix with or change to sleet near the South Coast especially Cape Cod. Temperatures steady 18-25 but can rise to 26-33 South Coast / Cape Cod and potentially as far north as the MA South Shore. Wind NE 15-25 MPH Cape Cod / Islands, NE to N 5-15 MPH elsewhere.

MONDAY: Mostly cloudy. Lingering snow or flurries. Total storm accumulation expectation is 10 to 16 inches, but pockets of 16 to 22 inches are possible, and areas of under 10 inches are possible mainly Cape Cod / Islands, pending the impact of potential sleet. Temperatures remain generally steady or fall slightly. Wind N to NW 10-20 MPH, a few higher gusts.

MONDAY NIGHT: Partly cloudy. A lingering snow flurry possible. Lows 12-18. Wind NW 10-20 MPH.

TUESDAY: Partly cloudy. Highs 22-29. Wind NW 10-20 MPH.

DAYS 6-10 (JANUARY 28 – FEBRUARY 1)

A passing disturbance may bring a few snow showers January 28. Watching for the next potential storm in the January 30 to February 1 time frame. Temperatures below normal.

DAYS 11-15 (FEBRUARY 2-6)

Another potential winter weather threat around February 5 in a still active and cold weather pattern.

DAYS 1-5 (JANUARY 22-26)

A warm front went by overnight, producing a period of snow inland and mix to rain along the coast. Today’s weather will be fairly benign, though breezy, and on the mild side compared to the last few days. Cold front #1 goes by late today with little fanfare, just a wind shift and a modest drop in temperature. Cold front #2 goes by later Friday. This one is an arctic front, and can be accompanied by a snow shower or snow squall, and will introduce the colder air mass of the season so far Friday night into the weekend. Saturday’s weather is dry but bitterly cold along with wind that will ease up by later on in the day, and sunshine that will be filtered by high cloudiness fanning across the sky in advance of a winter storm that brings a significant snowfall to our region Sunday into Monday. This will take place as a fairly elongated low pressure area passes to our south. There is still a little uncertainty on the exact track of the low, but for our area this just determines the amount of moisture that falls and as a result the amount of snow. The most northernmost potential the low track has would bring some mixing to the South Coast, but I’m not going with this scenario at this time – just a straight up significant snowfall for the entire region. Additional details will be posted in comments below as I get more information about this upcoming event, and of course another full discussion will appear with tomorrow morning’s blog post.

TODAY: Partly sunny. Highs 40-47. Wind SW 10-20 MPH, gusts 25-35 MPH.

TONIGHT: Clearing. Lows 20-27. Wind W 10-20 MPH, higher gusts.

FRIDAY: Partly cloudy. A late-day snow shower or snow squall possible. Highs 30-37. Wind W 10-20 MPH, gusts 25-35 MPH.

FRIDAY NIGHT: Partly cloudy with a potential snow shower or snow squall early, then clear. Lows 2-9. Wind WNW 15-25 MPH, higher gusts. Wind chills below zero.

SATURDAY: Sun and high clouds. Highs 13-20. Wind WNW 10-20 MPH, higher gusts. Wind chills below 10.

SATURDAY NIGHT: Increasing clouds. Lows 3-10. Wind N 5-15 MPH, diminishing.

SUNDAY / SUNDAY NIGHT: Overcast with snow. Accumulations of greater than 6 inches regionwide likely. Temperatures slowly rise to 18-25. Wind N to NE 5-15 MPH except 15-25 MPH Cape Cod by later Sunday.

MONDAY: Mostly cloudy. Lingering snow or flurries with minor additional accumulation possible. Temperatures steady 18-25. Wind NE to NW 10-20 MPH.

DAYS 6-10 (JANUARY 27-31)

Generally dry and cold. A couple minor disturbances can bring a period of two of snow showers around January 28 & 30. Another storm system may approach at the very end of the period.

DAYS 11-15 (FEBRUARY 1-5)

Potential winter storm threats around February 1 and 5 in an active and fairly cold winter weather pattern.
