DAYS 1-5 (DECEMBER 22-26)

High pressure brings fair, chilly weather today. A fast-moving clipper low brings the region a general light snowfall Tuesday, though marginal temperatures mean that some rain will likely be involved along the South Coast. while the track of the initial low pressure is going to be to our north, the system will be redeveloping as it moves offshore, and a trough around the back side of the newly-developing low can prolong snow shower activity near the eastern coastal locations, especially Cape Ann to Cape Cod MA, Tuesday night to early Wednesday. The rest of Wednesday – Christmas Eve – looks dry as a small area of high pressure moves in. A weak trough can cause a quick snow flurry in some areas Christmas morning, but the remainder of Christmas Day – Thursday – will feature lots of clouds but will be precipitation-free. We’ll be watching low pressure tracking along a frontal boundary just to our south on Friday, bringing the chance of snow/mix/rain to the region. It’s a bit soon for detail on this, in terms of magnitude and type of precipitation across the region, but this will be fine-tuned over the next couple of days. For now, plan for the potential for some weather-impacted travel conditions on the day after Christmas.

TODAY: Sunshine and some cloud patches. Highs 30-37. Wind NW 10-20 MPH, diminishing late.

TONIGHT: Clouds increase . Lows 23-30. Wind variable up to 10 MPH.

TUESDAY: Cloudy with snow (except some mix/rain MA South Coast briefly to South Shore longer), accumulation 1 to 3 inches except less than 1 inch near the coast south of Boston. Highs 35-42. Wind variable 5-15 MPH.

TUESDAY NIGHT: Variably cloudy. Snow showers possible Cape Ann to Cape Cod with minor additional accumulation possible. Lows 18-25. Wind variable then N to NW 5-15 MPH except 15-25 MPH coast.

WEDNESDAY: Variably cloudy. Possible snow showers early favoring far eastern areas. Highs 32-39. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 20-27. Wind W up to 10 MPH.

THURSDAY (CHRISTMAS): Partly cloudy. A brief snow flurry possible in the morning. Highs 35-42. Wind W 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Lows 22-29. Wind variable up to 10 MPH.

FRIDAY: Overcast. Rain/mix/ice/snow chances. Highs 32-39. Wind variable 5-15 MPH.

DAYS 6-10 (DECEMBER 27-31)

Temperatures near to below normal with our region mostly on the colder side of a boundary. Some unsettled weather is still possible to likely during the December 27-28 weekend followed by a drier trend.

DAYS 11-15 (JANUARY 1-5)

Variable but overall near normal temperatures with a couple disturbances to bring some unsettled weather, but no indication of major storms in the early days of 2026.

DAYS 1-5 (DECEMBER 21-25)

The winter solstice occurs this morning at 10:03 a.m. EST! Our day will be fair and breezy but not too cold as moisture-starved low pressure passes to our north. Its cold front swings through later in the day and leads a colder air mass into the region for Monday with continued dry weather. A clipper low dives our way for Tuesday with a period of snow, except some mixing / rain along the coast for a time. I’m expecting generally minor accumulations with this event (mostly under but up to 3 inches of snow, depending on location). A quick passing trough can bring a snow flurry on Christmas Eve, otherwise generally fair weather is expected for the holiday period through Christmas Day.

TODAY: Partly sunny. Highs 40-47. Wind SW to W 10-20 MPH with higher gusts.

TONIGHT: Partly cloudy. Lows 21-28. Wind W to NW 10-20 MPH.

MONDAY: Mostly sunny. Highs 30-37. Wind NW 10-20 MPH, diminishing.

MONDAY NIGHT: Clear early, clouds return later. Lows 23-30. Wind S up to 10 MPH.

TUESDAY: Cloudy with snow (except a period of mix/rain coast), accumulation 1 to 3 inches except less than 1 inch near the coast. Highs 35-42. Wind variable 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 18-25. Wind variable to NW 5-15 MPH, higher gusts.

WEDNESDAY: Variably cloudy. Slight chance of a passing snow shower. Highs 32-39. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 20-27. Wind W up to 10 MPH.

THURSDAY (CHRISTMAS): Partly cloudy. Highs 35-42. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 26-30)

Up-and-down temperature pattern, leaning toward slightly below normal with a couple disturbances potentially bringing mostly minor precipitation events – storm track trend favoring them passing to our north in the expected large scale pattern.

DAYS 11-15 (DECEMBER 31 – JANUARY 4)

A similar pattern continues as we end 2025 and reach the first few days of the New Year.

DAYS 1-5 (DECEMBER 20-24)

On this final full day of astronomical autumn, we’ve lost the short-lived feeling of spring we had yesterday and returned to the feel of winter. Well, that covers everything except summer. 😉 Seriously though, we have seen the return of colder air, but not the degree of cold we experience for much of the first half of December. We’re now in a pattern of up and down temperatures, and while the “ups” in the coming days are not going to feature the springlike readings of Friday. We’ll see this shown by the fact the next low pressure area to impact our region is this weekend, and we’ll see high temps in the 30s today and over 40 Sunday in the warm sector as the low passes by to our north. This will be a moisture-starved system, and while I previously highlighted the slight chance for insignificant precipitation, I’m removing that from the forecast this weekend in favor of dry weather – just a variety of clouds with the warm front / cold front combo with the passing low pressure area. The departure of this one does pull some colder air in again for Monday, setting the stage for a snow/mix/rain event on Tuesday as the next clipper low moves through. There are still some finer details to work out with this one, like precipitation-type and more precise timing. It will not be a big event but it does have the potential to have some pre-Christmas travel impact. Whatever it has in store for us, off it goes Tuesday night and sets up a mostly dry, seasonable Christmas Eve. We will have to watch for a weak disturbance that can cause a quick snow shower that day or evening. The winter solstice occurs on Sunday morning at 10:03 a.m. EST.

TODAY: Sun followed by clouds. Highs 35-42. Wind W to SW 10-20 MPH, higher gusts.

TONIGHT: Variably cloudy. Lows 23-30. Wind SW 5-15 MPH, higher gusts.

SUNDAY: Partly sunny. Highs 40-47. Wind SW to W 10-20 MPH with higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 21-28. Wind W to NW 10-20 MPH.

MONDAY: Mostly sunny. Highs 30-37. Wind NW 10-20 MPH, diminishing.

MONDAY NIGHT: Clear early, clouds return later. Lows 23-30. Wind S up to 10 MPH.

TUESDAY: Cloudy through midday with a period of snow/mix north, mix/rain south. Variably cloudy with late-day snow/mix/rain showers possible. Highs 35-42. Wind variable 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 18-25. Wind variable to NW 5-15 MPH, higher gusts.

WEDNESDAY: Variably cloudy. Slight chance of a passing snow shower. Highs 32-39. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 25-29)

Up-and-down temperature pattern, leaning toward slightly below normal with a couple disturbances potentially bringing mostly minor precipitation events – storm track trend favoring them passing to our north in the expected large scale pattern.

DAYS 11-15 (DECEMBER 30 – JANUARY 3)

A similar pattern – a couple smaller low pressure systems with mostly minor impact, but causing variable temperatures, but near to slightly below normal for the period overall.

DAYS 1-5 (DECEMBER 19-23)

A strong low pressure area will track from the Great Lakes through southeastern Canada today and tonight. A surge of warm air has made it into our region ahead of this storm’s trailing cold front, and rain showers will move in and become numerous to widespread today ahead of this front, with one final cluster or line of moderate to heavy rain showers – slight chance of embedded thunder – as the front move through there region from west to east during this afternoon. A moderate to strong southerly wind will blow ahead of the front, with some local damage and resultant power outages possible. The wind shifts to west behind the front, a little less strong, at which time colder air will return, with a possible additional rain/mix/snow shower this evening as the temperature drops. Any standing water can freeze by early Saturday morning, so watch for icy patches on untreated surfaces that cannot fully dry out by then. Our weekend will be mainly dry, although a weaker, fast-moving low pressure area will be passing to our north. Its warm front goes by late Saturday and its cold front whistles through the region on Sunday. The former can produce a brief period of very light snow in southern NH and northern MA, and the latter can produce a rain or snow shower again favoring northern portions of the WHW forecast area, but more than likely the vast majority of if not all of the region will stay precipitation-free as this features passes by. What it will do is introduce another shot of colder air for Monday. This will be followed by yet another clipper-type system Tuesday that brings the chance of light snow/mix in the morning and a potential mix/snow shower in the afternoon, details to be determined by the exact track of the low pressure area. The winter solstice occurs on Sunday morning at 10:03 a.m. EST.

TODAY: Overcast with widespread rain showers including the slight chance of thunder, then a clearing trend begins west to east mid to late afternoon. Highs 55-62 but starting to fall later in the day. Wind S increasing to 15-25 MPH, gusts 45-55 MPH inland and 55-65 MPH coastal areas and some higher elevations, including isolated gusts above 65 MPH, then shifting to W from west to east later in the day and diminishing slightly. 10-20 MPH except 20-30 MPH South Coast, gusts as high as 45-55 MPH, strongest coastal areas and higher elevations, shifting to W from west to east midday on.

TONIGHT: Partly cloudy. A passing mix / snow shower possible. Lows 22-29. Wind W 10-20 MPH, gusts 25-35 MPH.

SATURDAY: Sun followed by clouds. Highs 35-42. Wind variable up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. A brief period of very light snow possible mainly north of Route 2. Lows 22-29. Wind SW 5-15 MPH,.

SUNDAY: Partly sunny. A brief rain shower possible. Highs 41-48. Wind SW 10-20 MPH.

SUNDAY NIGHT: Partly cloudy. A brief snow flurry possible. Lows 21-28. Wind NW 10-20 MPH.

MONDAY: Mostly sunny. Highs 30-37. Wind NW 10-20 MPH, diminishing.

MONDAY NIGHT: Clear early, clouds return later. Lows 23-30. Wind S up to 10 MPH.

TUESDAY: Cloudy with a chance of light snow/mix morning. Variably cloudy with a rain/mix/snow shower possible afternoon. Highs 35-42. Wind variable 5-15 MPH.

DAYS 6-10 (DECEMBER 24-28)

Up-and-down temperature pattern, leaning toward slightly below normal with a couple disturbances potentially bringing mostly minor precipitation events, timing TBD. A little more detailed outlook for this holiday period coming soon.

DAYS 11-15 (DECEMBER 29 – JANUARY 2)

A similar pattern – a couple smaller low pressure systems with mostly minor impact, but causing variable temperatures, leaning slightly colder than normal.

DAYS 1-5 (DECEMBER 18-22)

High pressure nearby moves offshore today with fair and milder weather for our region. Low pressure cranks up and heads through the Great Lakes and into southeastern Canada tonight through Friday. Stronger southerly winds develop as this system moves in and its cold front will sweep through with many hours of rain showers preceding it, and a final band or cluster of heavier showers including a low chance of embedded thunder. A wind shift to west takes place and it dries out other than the chance of an additional rain / snow shower as colder air returns Friday night. Saturday, winds slacken and we can expect a sun / cloud mix as a smaller clipper low moves through the Great Lakes. This system will pass north of our region Sunday when we’ll be briefly in its warm sector between a warm front, which may produce brief insignificant precipitation Saturday night, and its cold front, which may produce a sprinkle of rain Sunday daytime and maybe a snow flurry behind it at night. The winter solstice occurs at 10:03 a.m. EST on Sunday. Fair, colder weather is expected behind that low pressure area for Monday.

TODAY: Sun much of the time then clouds arrive late. Highs 44-51. Wind variable to S up to 10 MPH.

TONIGHT: Clouds thicken. Widespread rain showers arrive west to east overnight. Lows 37-44 evening, rising through 40s overnight. Wind S increasing to 10-20 MPH with higher gusts.

FRIDAY: Overcast with widespread rain showers including the slight chance of thunder, then a clearing trend begins west to east mid to late afternoon. Highs 55-62 but starting to fall later in the day. Wind S 10-20 MPH except 20-30 MPH South Coast, gusts as high as 45-55 MPH, strongest coastal areas and higher elevations, shifting to W from west to east midday on.

FRIDAY NIGHT: Partly cloudy. A passing mix / snow shower possible. Lows 22-29. Wind W 10-20 MPH, gusts 25-35 MPH.

SATURDAY: Sun followed by clouds. Highs 35-42. Wind variable up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. A brief period of very light snow possible mainly north of I-90. Lows 22-29. Wind SW 5-15 MPH,.

SUNDAY: Partly sunny. A brief rain shower possible. Highs 41-48. Wind SW 10-20 MPH.

SUNDAY NIGHT: Partly cloudy. A brief snow flurry possible. Lows 21-28. Wind NW 10-20 MPH.

MONDAY: Mostly sunny. Highs 30-37. Wind NW 10-20 MPH, diminishing.

DAYS 6-10 (DECEMBER 23-27)

Clipper low pattern and up-and-down temps, tending to be colder vs. milder. Watching for minor snow or snow shower events December 23 & 25, and a snow / mix / rain chance toward the end of the period.

DAYS 11-15 (DECEMBER 28 – JANUARY 1)

A similar pattern – a couple smaller low pressure systems with mostly minor impact, but causing variable temperatures, tending to slightly colder than normal.

DAYS 1-5 (DECEMBER 17-21)

High pressure sits to the south today with a low pressure trough approaching from the west. The moisture-starved trough will do nothing but help the breeze stay active and gusty today into tonight, and shift the wind a bit before the high pressure area noses in and diminishes the wind on Thursday, which will continue a trend to less chilly air. A stronger, larger low pressure area cutting through the Great Lakes Thursday night into Friday, then heading down the St. Lawrence Valley later Friday, will produce a stronger southerly wind, and with the help of a sharp cold front moving into the region, a solid band of rainfall, which will largely wipe out any snow and ice on the ground. As the front moves through, the rain shuts off, the wind shifts to west, and we see a return of dry, colder air Friday night through Saturday, though not as cold as the recent cold air mass we experienced. A weaker low will be passing north of our region on Sunday, and its warm front / cold front combo can produce brief precipitation around here, mainly northern areas, but this should be minor at best. Mainly noticed will be the mix of sun and clouds and breezy weather for Sunday. The winter solstice occurs on Sunday at 10:03 a.m. EST.

TODAY: Sunshine and high clouds. Highs 37-44. Wind SW 5-15 MPH with higher gusts.

TONIGHT: Partly cloudy. Lows 24-31. Wind SW 5-15 MPH shifting to NW with higher gusts.

THURSDAY: Sun much of the time then more clouds late. Highs 44-51. Wind variable to S up to 10 MPH.

THURSDAY NIGHT: Clouds thicken. Widespread rain showers arrive west to east overnight. Lows 37-44 evening, rising through 40s overnight. Wind S increasing to 10-20 MPH with higher gusts.

FRIDAY: Overcast with widespread rain showers including the slight chance of thunder during the morning. Showers end west to east with a sun / cloud mix developing during the afternoon. Highs 55-62 in the morning, falling through the 50s into the 40s from west to east during the afternoon. Wind S 10-20 MPH except 20-30 MPH South Coast, gusts as high as 45-55 MPH, strongest coastal areas and higher elevations, shifting to W from west to east midday on.

FRIDAY NIGHT: Partly cloudy. A passing snow shower possible. Lows 22-29. Wind W 10-20 MPH, gusts 25-35 MPH.

SATURDAY: Sun followed by clouds. Highs 35-42. Wind variable up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. A brief period of very light snow possible mainly north of I-90. Lows 22-29. Wind SW 5-15 MPH,.

SUNDAY: Partly sunny. A late-day snow shower possible. Highs 38-45. Wind W 10-20 MPH.

DAYS 6-10 (DECEMBER 22-26)

Clipper low pattern and up-and-down temps, tending to be colder vs. milder. Watching for minor snow or snow shower events, timing uncertain from December 23 on.

DAYS 11-15 (DECEMBER 27-31)

We head down the home stretch of December and 2025 with a similar pattern continuing – up and down temps and the chance of one or two mainly minor precipitation events, timing and details TBD.

DAYS 1-5 (DECEMBER 16-20)

An atmospheric inversion results in a lot of clouds to start our day today but sun will make a return as the atmosphere mixes. It will be chilly, but not as cold as yesterday, and also less breezy, so a nice mid December day overall. The very modest temperature moderation today becomes more noticeable Wednesday and especially Thursday as high pressure slides offshore and a southerly air flow develops. This sets the stage for a brief warmer, wet weather event as low pressure heads through the Great Lakes and into southeastern Canada Thursday night through Friday. A strong cold front will produce a band of rainfall here, but a quick ending to it return to dry, chilly weather will take place from west to east during the day Friday as the front sweeps through. Saturday will feature a seasonable chill and as the next clipper low approaches, it will be starved for moisture but can produce a brief snow shower at some point later Saturday.

TODAY: Clouds give way to sun. Highs 32-39. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Lows 15-22. Wind WSW up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 37-44. Wind WSW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows Lows 25-32. Wind SW 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Highs 44-51. Wind SW 10-20 MPH.

THURSDAY NIGHT: Cloudy. Widespread rain showers arrive west to east late evening and overnight. Lows 37-44 early, then rising slowly. Wind SW to S 10-20 MPH.

FRIDAY: Overcast with widespread rain showers morning, may end mixed with snow in higher elevations well northwest of Boston midday. A sun/cloud mix remainder of day with a chance of evening snow showers north and west of Boston. Highs 48-55 morning, followed by falling temperatures. Wind S 10-20 MPH, higher gusts, shifting to W.

FRIDAY NIGHT: Partly cloudy. A passing snow flurry possible. Lows 21-28. Wind W 10-20 MPH, higher gusts, diminishing overnight.

SATURDAY: Sun followed by clouds. A possible snow shower late-day or evening. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 21-25)

Weak system passes to north December 21, the day of the winter solstice (10:03 a.m. EST), and may produce a quick sprinkle of rain or flurry of snow, otherwise dry and breezy. Another weak system can produce rain or snow showers about December 23 before the next one approaches with a precipitation chance on Christmas – too soon for details.

DAYS 11-15 (DECEMBER 26-30)

Up and down temperature pattern with a couple precipitation events possible near the temperatures battle zone. No big storms indicated.

DAYS 1-5 (DECEMBER 15-19)

Yesterday’s light snowfall event set the stage for reinforcing cold, and today will indeed be an icebox day as a modified arctic chill dominates. The core of this cold will be here for a limited time though. Tonight, a weak disturbance passing through can cause some light snow showers, and then we’re back to fair weather for a few days along with a gradual temperature moderation into the middle of the week. Thursday and Friday, we’ll see low pressure track through the Great Lakes and into southeastern Canada. This will drag milder air into our region on a strengthening southerly wind Thursday into early Friday, until the low’s sharp cold front comes through from west to east with a band of rain Friday, then a return to windy, colder conditions behind the front later Friday. Watch for a few snow showers by Friday evening as a much colder westerly air flow is established.

TODAY: Sun followed by clouds. Highs 22-29. Wind NW 10-20 MPH, gusts 25-35 MPH. Wind chill often below 20 and at times below 10.

TONIGHT: Mostly cloudy. Scattered snow showers, favoring areas south of I-90. Lows 13-20. Wind NW to W diminishing to under 10 MPH.

TUESDAY: Mostly sunny. Highs 32-39. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind WSW up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 37-44. Wind WSW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows Lows 25-32. Wind SW 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Highs 44-51. Wind SW 10-20 MPH.

THURSDAY NIGHT: Cloudy. Widespread rain showers arrive west to east late evening and overnight. Lows 37-44 early, then rising slowly. Wind SW to S 10-20 MPH.

FRIDAY: Overcast with widespread rain showers morning, may end mixed with snow in higher elevations well northwest of Boston midday. A sun/cloud mix remainder of day with a chance of evening snow showers north and west of Boston. Highs 48-55 morning, followed by falling temperatures. Wind S 10-20 MPH, higher gusts, shifting to W.

DAYS 6-10 (DECEMBER 20-24)

Pattern in the days heading toward Christmas will feature up and down temps, leaning toward colder, and a couple minor precipitation events, details of which can be fine-tuned as we get closer to this time frame. The winter solstice occurs at 10:03 a.m. EST on December 21.

DAYS 11-15 (DECEMBER 25-29)

Up and down temp pattern continues. Another couple precipitation events likely occur but no major storms indicated by the overall pattern.

DAYS 1-5 (DECEMBER 14-18)

Low pressure passing by to our south today will begin to intensify but will start to pull away while doing so. This gives the region a glancing blow resulting in a light to borderline moderate snowfall, with highest accumulation of snow from Plymouth County MA to northern RI, and southward from there, although amounts may be slightly lower than the maximum totals due to some initial mixing with rain on Outer Cape Cod and Nantucket. We also have to watch for a wrap-around batch of snow showers, somewhat enhanced by the ocean, on the back side of the departing system. This can prolong the snow until later Sunday for eastern coastal areas. The timing is just a little slower for the ending, resulting in a slower start to the clearing trend following the storm. But it will clear out during Sunday night as a reinforcing shot of cold air arrives. This cold, along with a gusty wind, will make Monday a bit harsh. A disturbance coming quickly our way from the west northwest may bring a few snow showers to the region Monday night. The Tuesday through Thursday period will feature moderating temperatures and generally dry weather, although later on Thursday we’ll see increasing clouds and by night there can be some wet weather as we see a spike of warmer air arriving at that time, propelled our way by low pressure cutting through the Great Lakes.

TODAY: Overcast with snow through midday gradually tapering off from west to east thereafter – accumulations generally 1/2 to 2 inches except 2 to as much as 4 inches possible from the MA South Shore to South Coast regions. Highs 27-34, mildest Outer Cape Cod / Nantucket. Wind NE to N up to 10 MPH.

TONIGHT: Lingering clouds and possible early snow showers eastern areas, otherwise clearing west to east. Lows 12-19. Wind N to NW increasing to 10-20 MPH with higher gusts. Wind chill falls below 10.

MONDAY: Sunny start, then clouds return later. Highs 23-30. Wind NW 10-20 MPH, gusts 25-35 MPH. Wind chill below 20 at times.

MONDAY NIGHT: Mostly cloudy. Snow showers likely with some minor accumulation expected. Lows 13-20. Wind NW diminishing to under 10 MPH.

TUESDAY: Mostly sunny. Highs 31-38. Wind WNW 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind W up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 36-43. Wind WSW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows Lows 25-32. Wind SW 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Highs 44-51. Wind SW 10-20 MPH.

DAYS 6-10 (DECEMBER 19-23)

Great Lakes cutter low pressure sends a brief surge of warmer air in right at the start of the period and a strong cold front trailing from the low brings a band of rain before cold air returns with lots of wind. December 20-21 weekend looks mostly tranquil and dry with seasonably chilly weather. A little more up-and-down temp swinging with a minor system bring rain/snow shower chance early next week – more precise timing TBD. The winter solstice occurs at 10:03 a.m. EST on December 21.

DAYS 11-15 (DECEMBER 24-28)

The up-and-down temperature pattern continues but with a leaning toward the colder side overall. An additional episode or two of precipitation possible but early indications for no major storminess to occur, more overrunning type events with our region on the colder side of the boundary between Canadian cold and warmth to the south. This would favor frozen over liquid precipitation for our area.

DAYS 1-5 (DECEMBER 13-17)

The second weekend of December 2025 will be a cold one, and will include some snow for our region. There is a clipper-type low pressure system that will be racing our way, having taken a southeastward dive to our west then an eastward turn to pass just south of us as it begins to interact with another disturbance passing to our north. This triggers the low pressure area to start strengthening as it goes by. This quick-moving and fairly flat system has neither time nor orientation to become a bigger system in terms of impact for our region, but will produce a general light snow late tonight into Sunday, reinforcing cold air as it departs with Monday being a blustery day with well below normal temperatures for mid December. Another small disturbance coming our way from Canada via the Great Lakes may produce some snow showers and very minor accumulations Monday night but will quickly exit by early Tuesday. Heading toward the middle of next week, high pressure moves to our west then south and allows a temperature moderation with dry weather expected.

TODAY: Lots of clouds / limited sun. Highs 31-38. Wind W up to 10 MPH.

TONIGHT: Becoming overcast. Light snow develops from west to east late evening and overnight. Lows 21-28. Wind N up to 10 MPH.

SUNDAY: Overcast morning-midday with snow although mixed snow and rain possible Outer Cape Cod and Nantucket, with snow accumulation a coating to 2 inches in general except a swath of 2 to 4 inches possible from Plymouth County MA to Providence RI and 10 to 20 miles either side, favoring southward. Slow clearing trend west to east afternoon. Highs 27-34, mildest Cape Cod. Wind NE up to 10 MPH.

SUNDAY NIGHT: Early clouds linger Cape Cod, otherwise clear. Lows 13-20. Wind NW 10-20 MPH, higher gusts. Wind chill below 10 at times.

MONDAY: Sunny start, then clouds return later. Highs 23-30. Wind NW 10-20 MPH, higher gusts. Wind chill below 20 at times.

MONDAY NIGHT: Mostly cloudy. Snow showers likely with some minor accumulation expected. Lows 13-20. Wind NW diminishing to under 10 MPH.

TUESDAY: Mostly sunny. Highs 31-38. Wind WNW 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind W up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 36-43. Wind WSW 5-15 MPH.

DAYS 6-10 (DECEMBER 18-22)

The previously-mentioned up-and-down temperature pattern expectation is forecast with more confidence at this point, with a quick warm-up early in the period while low pressure cuts across the Great Lakes into southeastern Canada, dragging a sharp cold front with a rain shower band through sometime between late December 18 and early December 19, followed by a shot of cold air that is short-lived before another moderation and weaker low and frontal system coming through with a minor precipitation threat mid period (mix/rain if system track is north, mix/snow if system track is further south). A brief moderation potential with this before colder air returns again to end the period. The winter solstice occurs at 10:03 a.m. EST on December 21.

DAYS 11-15 (DECEMBER 23-27)

The up-and-down temperature pattern continues but with a leaning toward the colder side overall. An additional episode or two of precipitation possible but early indications for no major storminess to occur, more overrunning type events with our region on the colder side of the boundary between Canadian cold and warmth to the south. This would favor frozen over liquid precipitation for our area.

DAYS 1-5 (DECEMBER 12-16)

The cold side of December continues to be dominant today and for the coming several days as well. Blustery weather continue today between low pressure to our northeast and high pressure to our west. Winds will diminish tonight and Saturday as the high moves into the region. We then turn our attention to a clipper low pressure area which will redevelop as it remains progressive, passing just south of our region on Sunday. Its interaction with some jet stream energy to the north will help determine its rate of strengthening, which then determines how much moisture can be wrung out of the air in the form of snow over our region on Sunday – although marginal temperatures mean a snow/rain mix potential for Outer Cape Cod, Martha’s Vineyard, and Nantucket. This is not expected to be a prolific snow producer, but for much of the region can drop enough to require at least some limited snow removal operations, especially since we don’t warm up right after it, but go the other way with a shot of colder to follow it, but with dry weather Monday and Tuesday.

TODAY: Sun and passing clouds. Highs 28-35. Wind NW 10-20 MPH, gusts 25-35 MPH.

TONIGHT: Mostly clear. Lows 13-20. Wind W diminishing to under 10 MPH.

SATURDAY: A sun / cloud mix. Highs 31-38. Wind W up to 10 MPH.

SATURDAY NIGHT: Increasing clouds. Lows 21-28. Wind N up to 10 MPH.

SUNDAY: Cloudy. Snow likely, mostly light but may become moderate for a while, and may be mixed with rain Outer Cape Cod / Islands. Snow accumulation a coating to 2 inches except 2-4 inches in the Plymouth MA to Providence RI corridor. Highs 27-34, mildest Cape Cod. Wind NE up to 10 MPH.

SUNDAY NIGHT: Clearing. Lows 13-20. Wind NW 10-20 MPH, higher gusts. Wind chill below 10 at times.

MONDAY: Mostly sunny. Highs 23-30. Wind NW 10-20 MPH, higher gusts. Wind chill below 20 at times.

MONDAY NIGHT: Clear. Lows 10-17. Wind NW diminishing to under 10 MPH.

TUESDAY: Mostly sunny. Highs 31-38. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 17-21)

Up-and-down temperature pattern with one or two low pressure systems crossing the Great Lakes region. Limited moisture should keep any precipitation – rain favored for first system – rather brief. A second system’s track is close enough to carry a rain/mix/snow potential but no indications of a major system. The winter solstice occurs at 10:03 a.m. EST on December 21.

DAYS 11-15 (DECEMBER 22-26)

The up-and-down temperature pattern continues but with a leaning toward the colder side overall. An additional episode or two of precipitation possible but early indications for no major storminess to occur. Additional detail can be provided for this Christmas period as we get closer to it.

DAYS 1-5 (DECEMBER 11-15)

Cold air returns to the region today with active winds, a sun/cloud mix, and perhaps a few snow showers from the combination of cold air advection and limited Great Lakes moisture traveling into our region. Active wind continues tonight into Friday with dry weather and below normal temperatures, but a ridge of high pressure building in will help diminish the wind later Friday and Saturday with continued dry weather. A clipper low will travel just south of our region Sunday, and its interaction with a little energy passing by to our north will determine whether we see just a few snow showers or a more notable period of snow. I’m leaning toward the latter, with the best chance of accumulating snow being from the I-90 belt southward for Sunday – maybe a mix on the Outer Cape / Islands due to marginal temperatures there. Regardless of the solidity of the snow shield, this system exits and leads reinforcing cold into our region for Monday, and the wind will be back again at that time.

TODAY: Sun/cloud mix. Chance of snow showers mainly in the afternoon. Highs 32-39 this morning followed by a slow but steady decline. Wind NW 10-20 MPH, but gusting 25-45 MPH at times.

TONIGHT: Partly cloudy. Chance of a snow flurry in the evening. Lows 17-24. Wind NW 5-15 MPH.

FRIDAY: Partly to mostly sunny. Highs 33-40. Wind NW 5-15 MPH with higher gusts, gradually diminishing.

FRIDAY NIGHT: Partly cloudy. Lows 11-18 except 18-25 coastal and urban areas. Wind W under 10 MPH.

SATURDAY: Partly cloudy. Highs 31-38. Wind W up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 17-24. Wind variable under 10 MPH.

SUNDAY: Cloudy. Chance of snow or snow showers. Highs 25-32 except 28-35 South Coast. Wind N up to 10 MPH.

SUNDAY NIGHT: Clearing. Lows 13-20. Wind NW 10-20 MPH, higher gusts.

MONDAY: Mostly sunny. Highs 23-30. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (DECEMBER 16-20)

Low pressure tracks into the Great Lakes by the middle of next week with a quick shot of milder air here, then we enter an up-and-down temperature pattern with another small system bringing a chance of precipitation later in the period.

DAYS 11-15 (DECEMBER 21-25)

From the winter solstice to Christmas Day, the pattern can’t be forecast with high confidence, and there is still a lot of uncertainty with guidance inconsistencies, but my current leaning is milder than December has been but not persistently mild – more up and down temps and mostly minor precipitation events with a lot of detail to work out as we get closer to this period of time.

DAYS 1-5 (DECEMBER 10-14)

A mild interlude comes today ahead of a cold front that trails low pressure passing to our north. This front will bring a round of rain showers (maybe some mix higher elevations well north and west of Boston) later today before bringing back a cold air mass overnight that will then be with us into the upcoming weekend. Thursday, upper low pressure and (limited) Great Lakes moisture combine for a snow shower chance, then dry weather is expected with weak high pressure in control Friday through Saturday. Sunday’s weather is to be determined by the track of a clipper low and how much moisture it has to work with, but there is the chance of snow or snow showers from this system with cold air in place in our area. Fine-tuning on the Sunday forecast ahead…

TODAY: Some partial sun morning favoring eastern areas otherwise becoming mostly cloudy. Late-day rain showers from west to east, but may be mixed with snow in higher elevations from north central MA through southwestern NH. Highs 38-45. Wind SW 5-15 MPH.

TONIGHT: Mostly to partly cloudy. Rain showers possible in eastern areas in the evening. Icy areas on untreated surfaces overnight. Lows 28-35. Wind NW 5-15 MPH.

THURSDAY: Sun/cloud mix. Chance of snow showers. Highs 32-39. Wind NW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Chance of a snow flurry. Lows 17-24. Wind NW 5-15 MPH.

FRIDAY: Partly to mostly sunny. Highs 33-40. Wind NW 5-15 MPH with higher gusts, gradually diminishing.

FRIDAY NIGHT: Partly cloudy. Lows 11-18 except 18-25 coastal and urban areas. Wind W under 10 MPH.

SATURDAY: Partly cloudy. Highs 31-38. Wind W up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 17-24. Wind variable under 10 MPH.

SUNDAY: Cloudy. Chance of snow or snow showers. Highs 25-32. Wind N up to 10 MPH.

DAYS 6-10 (DECEMBER 15-19)

A little more up and down temps possible in this period with low pressure track somewhat variable, potentially one or two systems passing over or north of here, but this is also somewhat uncertain. A lot to work out for detail during this stretch of time.

DAYS 11-15 (DECEMBER 20-24)

Similar ideas going into this period as well but leaning colder over warmer with a couple precipitation opportunities. With it a very low confidence forecast period I won’t venture into anymore detailed explanation than that at this point.

DAYS 1-5 (DECEMBER 9-13)

No notable changes for today’s discussion from yesterday’s. A warm front approaches today and tonight and a short wave disturbance aloft comes through this evening. While there is dry air to overcome at mid levels, this feature is expected to produce a brief period of snow late evening into the overnight hours from west to east, except mix to rain closer to Cape Cod where the temperature will be borderline between supporting frozen and liquid precipitation. If any accumulation of snow occurs with this, it will be minor and mostly away from the coast northwest of Boston. We end up in the “warm” sector for Wednesday, not an overly warm day by December standards, but milder than recent days for sure. A cold front trailing low pressure passing to our north will sweep through with the air mild enough for rain showers in the evening, again progressing west to east but lasting no more than a couple hours in any one location. This front will lead a colder air mass back into our region for Thursday through Saturday. Thursday’s weather will be windiest, with a gradual abatement of the wind on Friday and a more tranquil Saturday as high pressure builds toward the region. Upper level low pressure crossing the region, combined with limited Great Lakes moisture, can result in a few snow showers around the area Thursday. This threat will diminish then vanish for late week as the upper low departs and the wind relaxes.

TODAY: Sun gives way to clouds. Highs 28-35. Wind variable to SE up to 10 MPH.

TONIGHT: Cloudy evening into overnight with a period of light snow/mix except mix/rain South Coast. Snow accumulation of up to but mainly under 1/2 inch can occur mainly inland areas to the north of I-90. Watch for icy spots on untreated surfaces mid to late evening except Cape Cod / Islands. Lows 20-27 except steady 28-35 southeastern MA and southern RI evening, rising slowly overnight. Wind SE under 10 MPH shifting to SW up to 10 MPH.

WEDNESDAY: Partly sunny morning. Mostly cloudy afternoon. Late-day rain showers from west to east, but may be mixed with snow in higher elevations from north central MA through southwestern NH. Highs 38-45. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly to partly cloudy. Rain showers possible in eastern areas in the evening. Icy areas on untreated surfaces overnight. Lows 28-35. Wind NW 5-15 MPH.

THURSDAY: Sun/cloud mix. Chance of snow showers. Highs 32-39. Wind NW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Chance of a snow flurry. Lows 17-24. Wind NW 5-15 MPH.

FRIDAY: Partly to mostly sunny. Chance of a snow flurry early. Highs 34-41. Wind NW 5-15 MPH with higher gusts, gradually diminishing.

FRIDAY NIGHT: Partly cloudy. Lows 11-18 except 18-25 coastal and urban areas. Wind W under 10 MPH.

SATURDAY: Partly cloudy. Highs 31-38. Wind W up to 10 MPH.

DAYS 6-10 (DECEMBER 14-18)

Low pressure brings a chance of snow except snow/mix/rain South Coast during December 14, this being the next in a series of clipper-style low pressure areas. Watching for another system with a precipitation threat around December 17 but less confident on timing. Temperatures mostly below normal for the period.

DAYS 11-15 (DECEMBER 19-23)

Divergence in medium range guidance – nothing new there – doesn’t help forecast confidence atop the normal lower confidence for a period of time this far in the future. For now, the same idea applies. Watching for a brief warm-up from a Great Lakes low then a return to the colder pattern and back on the watch for clipper disturbances as the cold air wins out over a warmer area of air to our south. Caveat: There is enough push from medium range guidance including some ensemble support of a milder scenario toward Christmas – the days just before – so I am not completely discounting a shift to a milder outlook than the one I have now, hence the mention of low confidence.

DAYS 1-5 (DECEMBER 8-12)

This week we will have a parade of small and generally weak to borderline moderate disturbances and low pressure areas moving through our region. The overall pattern is cold, but there will be one brief milder interlude ahead of one of the systems. We had a weak system go by to our north last evening with a few snow flurries in southern NH and far northern MA, as was expected, but nothing to the south. Today’s weather is dry and chilly. The chill continues tomorrow as clouds increase ahead of a warm front, which can produce a period or two of light snow, mainly from the I-90 belt northward, sometime at night. This will lead in the brief shot of milder air for Wednesday ahead of a cold front, trailing the next low passing to our north. This results in a rain shower chance from midday to early evening Wednesday. After the front goes by, colder air returns and untreated surfaces will become icy by early Thursday morning. Thursday’s weather will be blustery and colder with a chance of passing snow showers as upper level low pressure moves overhead. The cold hangs on but the wind will ease up during Friday as low pressure moves away and high pressure builds in with dry weather.

TODAY: Abundant sun. Highs 23-30 except 28-35 South Coast. Wind NW 5-15 MPH, gusts 20-25 MPH.

TONIGHT: Clear. Lows 8-15 except 15-22 South Coast. Wind NW 5-15 MPH shifting to SW and diminishing.

TUESDAY: Sun gives way to clouds. Highs 28-35. Wind variable to SE up to 10 MPH.

TUESDAY NIGHT: Cloudy. A period or two of light snow favoring I-90 northward late evening. Chance of mix to rain showers south of I-90 overnight. Lows 20-27 except steady 28-35 southeastern MA and southern RI evening, rising slowly overnight. Wind SE under 10 MPH shifting to SW up to 10 MPH.

WEDNESDAY: Mostly cloudy. Midday and afternoon rain showers likely, may be mixed with snow in southwestern NH and north central MA higher elevations. Highs 38-45. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly to partly cloudy. Rain showers possible in eastern areas in the evening. Icy areas on untreated surfaces overnight. Lows 28-35. Wind NW 5-15 MPH.

THURSDAY: Sun/cloud mix. Chance of snow showers. Highs 32-39. Wind NW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Chance of a snow flurry. Lows 17-24. Wind NW 5-15 MPH.

FRIDAY: Partly to mostly sunny. Chance of a snow flurry early. Highs 34-41. Wind NW 5-15 MPH, diminishing.

DAYS 6-10 (DECEMBER 13-17)

Overall pattern is cold and features at least a couple disturbances / low pressure areas moving by quickly with precipitation opportunities. Hard to time and detail these chances beyond 5 days out, but will bring them into better focus as they get closer.

DAYS 11-15 (DECEMBER 18-22)

This period remains low confidence in forecasting, but still watching for a Great Lakes low pressure area to allow a short-lived warm-up and a chance of some snow/mix/rain, before cold returns with any disturbances bringing some snow or snow shower chances. Again no real detail or timing is possible this far in advance.
