DAYS 1-5 (JANUARY 2-6)

The next few days will see us in a dry, colder trend, with persistent northwesterly air flow. Today, winds will be significant, with gusts over 40 MPH common in the region. A slight chance of a passing rain or snow shower exists, and an additional snow shower can drift by Friday and/or Saturday, otherwise the theme is breezy, cold, and dry through the weekend. Monday, we’ll watch a wave of low pressure passing to our south, which is still expected to pass mostly to the south, but may be close enough to throw a swath of light snow into southern areas. There’s still some uncertainty with that low’s track, so it’ll be monitored closely for any changes.

TODAY: Partly sunny. Chance of brief passing rain / snow showers. A couple snow showers may be briefly heavy with minor accumulation in areas well west of Boston. Highs 36-43. Wind NW 15-25 MPH, gusts 30-50 MPH, strongest over open areas and higher elevations.

TONIGHT: Partly cloudy. Lows 22-29. Wind NW 15-25 MPH, higher gusts.

FRIDAY: Partly cloudy. Chance of a brief passing snow shower. Highs 31-38. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 15-22. Wind NW 10-20 MPH, a few higher gusts.

SATURDAY: Mostly sunny to partly cloudy. A slight chance of a brief passing snow flurry. Highs 27-34. Wind NW 10-20 MPH, a few higher gusts possible.

SATURDAY NIGHT: Mostly clear. Lows 12-19. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 25-32. Wind NW 5-15 MPH.

SUNDAY NIGHT: Increasing clouds. Lows 12-19. Wind NW to N up to 10 MPH.

MONDAY: Cloudy. Chance of light snow South Coast. Highs 22-29. Wind N up to 10 MPH.

DAYS 6-10 (JANUARY 7-11)

Cold and dry pattern. Suppressed storm track keeps snow threats to south.

DAYS 11-15 (JANUARY 12-16)

Cold relaxes slightly, but storm track also edges closer with a potential storm threat evolving.

DAYS 1-5 (JANUARY 1-5)

Happy New Year! Low pressure sitting over our area starts our 2025 out on a cloudy, damp note. While a belt of heavier rain and embedded thunderstorms has moved on, and some additional rain lingers as we start daylight, we’ll see this taper to lingering drizzle and light rain showers with areas of fog as low pressure lifts northeastward into the Gulf of Maine. This process will allow a transition from the variable and light wind of early morning to a westerly breeze during the course of the day, but one more batch of showers will cross the region from west to east this evening, mainly as rain except some snow mixing in over higher elevations to the west. After this, we enter a 4-day period of colder trend with mainly dry weather. A passing rain or snow shower is possible Thursday, and a passing snow shower can occur Friday and/or Saturday, but by and large we’re just looking at dry weather and a bit colder each day, including Sunday. During this time, our departed storm system will evolve into a quasi stationary Atlantic Canada low with a large circulation, and this will keep the wind active here, especially on Thursday with notably strong gusts will occur. A very gradual lessening of wind will occur each day after that, but it will remain breeze through the first weekend of 2025.

TODAY (NEW YEAR’S DAY): Cloudy. Rain tapers to patchy drizzle / scattered rain showers. Areas of fog through midday. Highs 45-52. Wind E 5-15 MPH with higher gusts early, becoming variable around 10 MPH, then W 5-15 MPH with higher gusts later in the day.

TONIGHT: Cloudy with rain showers except mixed rain/snow showers higher elevations to the west this evening. Partly cloudy overnight. Lows 30-37. Wind W 10-20 MPH, higher gusts developing.

THURSDAY: Partly sunny. Chance of brief passing rain / snow showers. Highs 36-43. Wind NW 15-25 MPH, gusts 30-50 MPH, strongest over open areas and higher elevations.

THURSDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 15-25 MPH, higher gusts.

FRIDAY: Partly cloudy. Chance of a brief passing snow shower. Highs 31-38. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 15-22. Wind NW 10-20 MPH, a few higher gusts.

SATURDAY: Mostly sunny to partly cloudy. A slight chance of a brief passing snow flurry. Highs 27-34. Wind NW 10-20 MPH, a few higher gusts possible.

SATURDAY NIGHT: Mostly clear. Lows 12-19. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 25-32. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 6-10)

The theme is cold and mainly dry with a suppressed storm track keeping any significant snow to the south of our region, but still have to watch a system early in the period as it goes by, just in case.

DAYS 11-15 (JANUARY 11-15)

Cold pattern continues. Dry at first, then a snow threat mid or late period. Too soon for any further detail.

DAYS 1-5 (DECEMBER 31 – JANUARY 4)

An area of high pressure to the south of New England slides eastward, providing fair weather for the final day of 2024 today. The air flow will shift from light westerly to southerly during the day. Clouds will be on the increase ahead of an approaching low pressure area, which will deliver a slug of rain to the region as we ring in 2025. The main rain area ahead of the low center will arrive in much of CT, RI, and southern MA prior to midnight, but should hold off until around or after midnight from Metro Boston northward. The main rain area than moves through overnight and exits by early morning. As a low pressure center comes right up over the region from the southwest, a short-lived easterly breeze ahead of it will become light and variable through midday Wednesday, with areas of drizzle and a few rain showers lingering, and also the opportunity for some fairly significant fog to form. As the low center starts to pull away to the north later Wednesday, a drying westerly air flow will take over, and a clearing trend will begin by evening and continue during the night. Thursday through Saturday will feature mostly dry weather outside of the chance of a passing rain or snow shower Thursday and snow flurry on Friday, but these will be fairly windy days, especially Thursday, along with a trend to colder weather daily.

TODAY: Sun followed by increasing clouds. Highs 45-52. Wind W up to 10 MPH, shifting to S.

TONIGHT (NEW YEAR’S EVE): Cloudy. Rain arrives southwest to northeast. Areas of fog forming. Lows 38-45. Wind S shifting to E and increasing to 5-15 MPH.

WEDNESDAY (NEW YEAR’S DAY): Cloudy. Rain tapers to patchy drizzle / scattered rain showers. Areas of fog through midday. Highs 45-52. Wind E 5-15 MPH with higher gusts early, becoming variable around 10 MPH, then W 5-15 MPH with higher gusts later in the day.

WEDNESDAY NIGHT: Breaking clouds. Lows 30-37. Wind W 10-20 MPH, higher gusts developing.

THURSDAY: Partly sunny. Chance of brief passing rain / snow showers. Highs 36-43. Wind NW 15-25 MPH, gusts 30-50 MPH, strongest over open areas and higher elevations.

THURSDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 15-25 MPH, higher gusts.

FRIDAY: Partly cloudy. Chance of a brief passing snow flurry. Highs 31-38. Wind NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 15-22. Wind NW 10-20 MPH, a few higher gusts.

SATURDAY: Mostly sunny to partly cloudy. Highs 27-34. Wind NW 10-20 MPH, a few higher gusts possible.

DAYS 6-10 (JANUARY 5-9)

Dry, colder, but more tranquil weather January 5 as high pressure moves in. Window of opportunity for snow exists from late January 6 through January 7 as low pressure passes south of the region – the track to be the determining factor on how much snow makes it into this area. A miss to the south is also a potential. Fair, cold weather follows that for late period.

DAYS 11-15 (JANUARY 10-14)

Pattern will feature below normal temperatures into the middle of January. Watching another window of opportunity for a snow event mid to late period, otherwise the pattern is mainly dry.

DAYS 1-5 (DECEMBER 30 – JANUARY 3)

Quick-hitting rain this morning as a cold front crosses the region. A follow-up trough may trigger one more quick round of showers early this afternoon especially west and north of Boston. This will be followed by drier weather later today and during the daytime / evening of Tuesday. Another low pressure area moves in and delivers its rain shield to our region as 2025 begins, but this system, while it’s wrapping up nicely in the jet stream, will be progressive enough that the rain doesn’t hang around too long – into the late morning hours of New Year’s Day, before it tapers off and we just have some lingering clouds and sprinkles of rain that afternoon. Breezy / windy, dry weather is then ours behind that storm system Thursday and Friday with a colder trend. I can’t rule out a brief passing rain or snow shower Thursday and snow flurry Friday.

TODAY: Overcast with widespread rain showers crossing the region through mid morning. Clearing trend midday on including some afternoon sunshine. Watch for one additional passing rain shower early afternoon mainly north and west of Boston. Highs 53-60 early, then a slight / slow temperature fall during the daytime. Wind S shifting to SW 5-15 MPH, gusts 20+ MPH.

TONIGHT: Mostly clear. Lows 31-38. Wind WSW 5-15 MPH.

TUESDAY: Sun followed by increasing clouds. Highs 45-52. Wind W 5-15 MPH, diminishing and becoming variable.

TUESDAY NIGHT (NEW YEAR’S EVE): Cloudy. Rain arrives overnight. Areas of fog forming. Lows 38-45. Wind variable to E increasing to 5-15 MPH.

WEDNESDAY (NEW YEAR’S DAY): Cloudy. Rain tapers to patchy drizzle / sprinkles. Areas of fog through midday. Highs 45-52. Wind E 5-15 MPH with higher gusts early, becoming variable around 10 MPH, then W 5-15 MPH with higher gusts later in the day.

WEDNESDAY NIGHT: Breaking clouds. Lows 30-37. Wind W 10-20 MPH.

THURSDAY: Partly sunny. Chance of brief passing rain / snow showers. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 10-20 MPH.

FRIDAY: Partly cloudy. Chance of a brief passing snow flurry. Highs 31-38. Wind NW 10-20 MPH.

DAYS 6-10 (JANUARY 4-8)

Below normal temperature pattern will be established during this time. Watching for a storm impact potential January 6-7 time frame after a tranquil January 4-5 weekend. Will monitor and update as always.

DAYS 11-15 (JANUARY 9-13)

Below to much below normal temperatures. Leaning dry for the weather with occasional snow showers, but have to watch disturbances passing to south in case they are close enough for impact.

DAYS 1-5 (DECEMBER 29 – JANUARY 2)

A dense fog sits across much of the WHW forecast area early this morning, and will be a hindrance to travel. This fog has thinned out and dissipated along the South Coast where a warm front has now moved through, and this front will progress northward, along with a band of rain showers. As it moves along, the fog will gradually diminish and temperatures will rise. The low pressure area pulling this front through will then send its cold front through the region Monday morning, with widespread rain showers. Drier air arrives behind that front during the afternoon and evening, and a weak area of high pressure sliding by to our south provides fair weather for the final day of 2024 on Tuesday. Another low pressure area moves our way for the first day of 2025 on Wednesday. This one will bring another slug of mainly rain to the region, though its track right over the region means that some higher elevation areas well north and west of Boston may be borderline in temperature so that some mixed precipitation may be part of the event. A little bit of fine-tuning needs to be done ahead of that system. Behind that system, colder air begins to move into the region along with a gusty wind and a chance of a few rain and/or snow showers on Thursday.

TODAY: Cloudy. Widespread fog, gradually dissipating from south to north. Scattered to numerous rain showers moving south to north through the region morning through midday. Highs 45-52, mildest to the south of I-90. Wind calm except S up to 10 MPH South Coast early, then S 5-15 MPH.

TONIGHT: Cloudy. Patchy fog returns. Widespread rain showers arrive around dawn from west to east. Temperatures steady 45-52 then a slow rise. Wind S 5-15 MPH, higher gusts especially along the South Coast.

MONDAY: Overcast with areas of fog and widespread rain showers morning-midday. Breaking clouds later in the day. Highs 50-57. Wind SE 5-15 MPH with higher gusts, shifting to SW.

MONDAY NIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

TUESDAY: Partly sunny. Highs 41-48. Wind W 5-15 MPH in the morning, diminishing and becoming variable.

TUESDAY NIGHT (NEW YEAR’S EVE): Mostly cloudy. Lows 33-40. Wind variable to E up to 10 MPH.

WEDNESDAY (NEW YEAR’S DAY): Overcast. Rain likely with areas of fog. Some mixed precipitation potential higher elevations southwestern NH and north central MA. Highs 38-45. Wind E 5-15 MPH, higher gusts, becoming variable, then shifting to W late-day.

WEDNESDAY NIGHT: Breaking clouds. Lows 30-37. Wind W 10-20 MPH.

THURSDAY: Variably cloudy. Chance of brief passing rain / snow showers. Highs 38-45. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 3-7)

Solid colder pattern becomes established. Mainly dry or isolated snow showers at first (January 3), a dry January 4-5 weekend, then a winter storm potential early the following week (January 6-7).

DAYS 11-15 (JANUARY 8-12)

Below to much below normal temperatures as a cold wave overtake the region. Too soon to say if additional important storminess is a factor, or just occasional snow showers. Leaning toward the drier side on the pattern but much uncertainty that far in the future.

DAYS 1-5 (DECEMBER 27 – JANUARY 1)

Scattered rain / drizzle in the region this morning can freeze on surfaces especially outside of urban centers and away from the coast. Areas vulnerable include Metro Boston and I-95 belt westward and northward. Temperatures should rise sufficiently, albeit slowly, especially over interior valley areas, so that the icing issue comes to an end during the midday hours. By then, most of the patchy rainfall, associated with an approaching warm front, will have ended. The front will take until Sunday to fully push through the region, probably accompanied by some additional light rainfall, but this time with surface temperatures above freezing across the region – so no icing threat. While the low pressure area parenting that front passes to our north, its trailing cold front will bring a ribbon of rainfall to the region Monday, mainly during the first half of the day, before the front passes and introduces a drying westerly air flow later in the day. A bubble of high pressure passing south of the region on the final day of 2024 Tuesday will exert enough influence for partial sunshine. Another low pressure system will be heading our way though, and 2025 will begin with an unsettled day Wednesday. The track of this low will be close to the region, and enough cold air may be present over interior locations for some mixed rain/snow or even some patchy icing conditions at least at the onset. It’s a bit too soon to pin down the details of this system, so check updates!

TODAY: Cloudy. Periods of light rain with icing inland locations morning to midday. Patchy drizzle with freezing drizzle inland thereafter. Highs 32-39, coldest interior locations north of I-90 and west of I-95, except 36-43 Cape Cod / Islands. Wind calm through midday then SE up to 10 MPH.

TONIGHT: Cloudy. Areas of fog. Patchy drizzle, which may freeze on surfaces far north and west of Boston initially. Temperatures rise to 40-47. Wind SE up to 10 MPH.

SUNDAY: Cloudy. Areas of fog. An additional period or two of rain possible. Highs 45-52, mildest interior locations south of I-90. Wind SE 5-15 MPH.

SUNDAY NIGHT: Overcast. Areas of fog. Temperatures steady 45-52 evening, may rise slightly overnight. Wind SE to S 5-15 MPH, higher gusts South Coast.

MONDAY: Overcast with areas of fog and widespread rain showers morning-midday. Breaking clouds later in the day. Highs 50-57. Wind SE 5-15 MPH with higher gusts, shifting to SW.

MONDAY NIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

TUESDAY: Partly sunny. Highs 41-48. Wind W 5-15 MPH in the morning, diminishing and becoming variable.

TUESDAY NIGHT (NEW YEAR’S EVE): Mostly cloudy. Lows 33-40. Wind variable to E up to 10 MPH.

WEDNESDAY (NEW YEAR’S DAY): Overcast. Rain likely with areas of fog. Some mix/ice potential well inland. Highs 38-45. Wind E 5-15 MPH, higher gusts.

DAYS 6-10 (JANUARY 2-6)

A few snow showers otherwise dry, windy, colder early in the period then more tranquil but cold mid period as high pressure replaces departing low pressure. Next storm threat comes at the end of the period but too early for details.

DAYS 11-15 (JANUARY 7-11)

Winter storm potential early in the period, followed by fair weather. Temperatures below to much below normal.

DAYS 1-5 (DECEMBER 27-31)

High pressure hangs on with fair weather today. Three unsettled days follow. A warm front approaches Saturday bringing clouds and a period of light rain during the morning to midday hours. However, with temperatures below freezing in many inland locations, especially north of I-90 and west of the I-95 belt, there will be patches of icing as a result. The warm front itself may take until sometime Sunday to pass through the region, and while any additional precipitation will be limited, some drizzle can occur, and this will be with inland temperatures still near to slightly below freezing for a while. Eventually all areas rise above freezing by sometime Sunday and thus the icing threat ends, but some additional rain can occur under a cloudy sky. Another ribbon of rain will move through the region Sunday night into Monday morning with the passage of a cold front, trailing low pressure passing to our north. Drier air arrives during Monday afternoon with improving weather, which will last into New Year’s Eve on Tuesday with a weak area of high pressure moving in for the final day of 2024.

TODAY: Sunshine. Highs 35-42. Wind variable under 10 MPH.

TONIGHT: Clouds increase. Lows 24-31. Wind variable under 10 MPH.

SATURDAY: Cloudy. A period of light rain with icing inland locations morning to midday. Patchy drizzle with freezing drizzle inland thereafter. Highs 30-37, coldest interior locations north of I-90 and west of I-95. Wind calm through midday then SE up to 10 MPH.

SATURDAY NIGHT / SUNDAY: Cloudy. Periodic rain and drizzle. Additional icing at first inland locations mainly well northwest of Boston. Areas of fog. Temperatures slowly rise to 40-47. Wind SE 5-15 MPH.

SUNDAY NIGHT: Overcast. Areas of fog. Rain likely. Temperatures rise slightly to 46-53. Wind SE 5-15 MPH with higher gusts.

MONDAY: Overcast with areas of fog and rain likely morning-midday. Breaking clouds later in the day. Highs 48-55. Wind SE 5-15 MPH with higher gusts, shifting to SW.

MONDAY NIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

TUESDAY: Partly sunny. Highs 41-48. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 1-5)

Low pressure brings a rain chance for the first day of 2025 (may be some inland mix with borderline temps). Drier, colder weather follows.

DAYS 11-15 (JANUARY 6-10)

Winter storm potential early in the period, followed by fair weather. Overall pattern is colder.

DAYS 1-5 (DECEMBER 26-30)

A low level inversion has delivered a large cloud patch to much of eastern MA and parts of RI, blotting out the sun as it rises early this morning, but this cloud area will break up and clear out from north to south by mid morning, and with high pressure in control today and again Friday, a stretch of fair, tranquil early winter weather will continue. But as optimistic as I was about our weekend yesterday, I need to be less so today, as high pressure will lose control sooner, sliding off to the east and weakening. While this happens, a low pressure trough approaches from the west. Clouds arrive Saturday, along with a milder southerly air flow, into Sunday as well. A frontal boundary will get closer to the region and waves of low pressure moving up along it, passing to our west, will deliver periodic rainfall to our region from late Saturday through Sunday. Does it get better Monday? It may be improving late in the day, but not before one more low pressure area brings a slug of soaking rain to the region. The benefits to the milder, wetter upcoming pattern are that stubborn icy areas on walkways will melt away, and rainfall will continue to reduce our ongoing drought.

TODAY: Early clouds eastern MA / RI, otherwise mostly sunny. Highs 33-40. Wind N up to 10 MPH.

TONIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny. Highs 35-42. Wind variable up to 10 MPH.

FRIDAY NIGHT: Mostly clear. Lows 19-26. Wind variable up to 10 MPH.

SATURDAY: Clouding over. Chance of rain late-day, which can be in the form of freezing rain in some portions of central MA and southern NH. Highs 35-42. Wind SE up to 10 MPH.

SATURDAY NIGHT / SUNDAY: Cloudy. Periodic rain and drizzle. Areas of fog. Temperatures rise to 40-47 then steady. Wind SE 5-15 MPH.

SUNDAY NIGHT: Overcast. Areas of fog. Rain likely. Temperatures rise slightly to 46-53. Wind SE 5-15 MPH with higher gusts.

MONDAY: Overcast with areas of fog and rain likely morning-midday. Breaking clouds later in the day. Highs 48-55. Wind SE 5-15 MPH with higher gusts, shifting to SW.

DAYS 6-10 (DECEMBER 31 – JANUARY 4)

A drier interlude on the final day of 2024 with an area of high pressure sliding just south of our region. Another low pressure area moves in with a rain chance for the first day of 2025. This will be followed by drier weather – maybe a few snow showers – and a colder trend in the early days of the New Year.

DAYS 11-15 (JANUARY 5-9)

This period looks more active with at least and probably 2 storm threats (rain/mix/snow TBD) as it’s far too soon to talk about details.

DAYS 1-5 (DECEMBER 25-29)

High pressure dominates and brings quiet late December weather from today into the weekend. This Christmas Day goes down as a white Christmas for a good part of the WHW forecast area which has at least 1 inch of snowcover, but the holiday itself presents great conditions for local and regional travel. Just watch for icy areas on the ground from the last couple events where there has not been a sufficient melt / dry cycle. Otherwise, not much to talk about with the high pressure area dominating. By Sunday though, we’ll see more cloudiness as the high starts to drift away and a large scale trough approaches from the west.

TODAY (CHRISTMAS DAY): Partly sunny. Highs 28-35. Wind N 5-15 MPH.

TONIGHT: Partly cloudy. Lows 20-27. Wind N up to 10 MPH.

THURSDAY: Mostly sunny. Highs 33-40. Wind N up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny. Highs 35-42. Wind variable up to 10 MPH.

FRIDAY NIGHT: Mostly clear. Lows 17-24. Wind variable up to 10 MPH.

SATURDAY: Mostly sunny. Highs 38-45. Wind variable up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. Lows 30-37. Wind SE 5-15 MPH.

SUNDAY: Mostly cloudy. Highs 40-47. Wind S 5-15 MPH.

DAYS 6-10 (DECEMBER 30 – JANUARY 3)

Low pressure coinciding with milder air aloft brings a rain chance late December 30 (may have to watch for inland icing for part of the event). Another precipitation threat comes January 1 and/or 2.

DAYS 11-15 (JANUARY 4-8)

Colder trend. Mid to late period potential storm threat.

DAYS 1-5 (DECEMBER 24-28)

A band of snow showers will cross the region from west to east this morning, producing a minor accumulation (generally under 1 inch), except it will struggle to do that the further southeast you go due to a bit less snow and a bit “milder” air there, and may be mixed with rain across Cape Cod. This exits with the passage of a cold front trailing low pressure going by to our north this afternoon, and dry weather returns for Christmas Eve and Christmas Day as high pressure starts to build in. This more tranquil weather then holds into late week as high pressure dominates.

TODAY: Cloudy morning with a period of snow showers – accumulating a coating to 1 inch – except rain and snow showers Cape Cod. Clouds break for partial sun this afternoon. Highs 31-38. Wind SW 5-15 MPH shifting to NW.

TONIGHT: Partly cloudy except mostly cloudy Cape Cod. Lows 16-23. Wind N 5-15 MPH.

WEDNESDAY (CHRISTMAS DAY): Partly sunny. Highs 28-35. Wind N 5-15 MPH.

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

THURSDAY: Mostly sunny. Highs 33-40. Wind N up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny. Highs 35-42. Wind variable up to 10 MPH.

FRIDAY NIGHT: Mostly clear. Lows 17-24. Wind variable up to 10 MPH.

SATURDAY: Mostly sunny. Highs 38-45. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 29 – JANUARY 2)

Low pressure coinciding with milder air aloft brings a rain chance late December 29 and December 30 (may have to watch for inland icing for part of the event). Another precipitation threat comes January 1 and/or 2.

DAYS 11-15 (JANUARY 3-7)

Colder trend. Mid to late period potential storm threat.

DAYS 1-5 (DECEMBER 23-27)

Some ocean-effect snow showers dusted parts of the South Shore (including areas that missed out on snow from the last event) and parts of Cape Cod overnight, but these have moved offshore. High pressure brings cold, dry, tranquil weather to our region for today. Low pressure moving across northern New England Tuesday sends a warm front through the region with a brief period of snow favoring areas north of I-90 in the pre-dawn hours, followed by a cold front which will produce a band of snow showers (rain or snow showers for Cape Cod) Tuesday morning to midday. Dry weather returns for Christmas Eve and Christmas Day as this system departs and high pressure moves in. With a snow cover in much of the region not going anywhere, this will qualify as a white Christmas for a good portion of the region. Only some areas well to the west and north may lack sufficient snowcover, as well as a small area of southeastern MA which got little or no snow during the recent event. High pressure will hold on with dry weather and a slight temperature moderation late this week, but no big warm-up.

TODAY: Sunshine becoming filtered by an increase in high cloudiness. Highs 23-30. Wind variable up to 10 MPH.

TONIGHT: Thickening overcast. A period of light snow favoring areas north of I-90 in the overnight hours with a very minor accumulation. Lows 16-23 occurring before midnight, followed by a slow temperature rise overnight. Wind variable under 10 MPH becoming SW up to 10 MPH overnight.

TUESDAY (CHRISTMAS EVE): Mainly cloudy through midday with a period of snow showers (except rain or snow showers Cape Cod) from northwest to southeast with accumulation of snow up to 1/2 inch possible. Becoming partly to mostly sunny behind this also from northwest to southeast during the afternoon. Highs 31-38. Wind SW 5-15 MPH, shifting to NW.

TUESDAY NIGHT: Partly cloudy except mostly cloudy Cape Cod. Lows 16-23. Wind N 5-15 MPH.

WEDNESDAY (CHRISTMAS DAY): Partly sunny. Chance of light snow showers Cape Cod. Highs 28-35. Wind N 5-15 MPH.

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

THURSDAY: Mostly sunny. Highs 33-40. Wind N up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 28 – JANUARY 1)

A quiet pattern with seasonable temperatures (slight moderating trend) for the final handful of 2024 days. Unsettled weather may be here by the first day of 2025.

DAYS 11-15 (JANUARY 2-6)

Early period and late period low pressure impacts are possible, but too soon for details.

DAYS 1-5 (DECEMBER 22-26)

An arctic air mass is in place and will hang around through Monday as high pressure builds toward the region today and crests over the region Monday. A low pressure area will move through our region Tuesday with a pre-dawn episode of light snow and some daytime snow showers, producing minor snowfall accumulation in some areas. High pressure builds back in with fair weather for Christmas Day and Thursday.

TODAY: Mostly sunny except partly cloudy with possible snow showers Outer Cape Cod. Highs Highs 18-25. Wind NW 5-15 MPH.

TONIGHT: Mostly clear except partly cloudy with additional snow showers possible Outer Cape Cod. Lows 5-12 except 12-17 immediate coast / urban centers. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 23-30. Wind variable up to 10 MPH.

MONDAY NIGHT: Clouding up. A period of light snow overnight with minor accumulation (under 1 inch). Lows 15-22. Wind variable under 10 MPH.

TUESDAY (CHRISTMAS EVE): Variably cloudy. Good chance of snow showers through midday. Highs 27-34. Wind variable to W up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 18-25. Wind NW 5-15 MPH.

WEDNESDAY (CHRISTMAS DAY): Partly sunny. Chance of light snow showers in eastern areas. Highs 32-39. Wind N 5-15 MPH.

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

THURSDAY: Mostly sunny. Highs 33-40. Wind N up to 10 MPH.

DAYS 6-10 (DECEMBER 27-31)

Tranquil pattern with a slight moderation in temperature and no major storminess.

DAYS 11-15 (JANUARY 1-5)

A low pressure system brings a precipitation threat early in the period before dry weather returns with a colder trend getting underway.

DAYS 1-5 (DECEMBER 21-25)

Welcome to winter! The solstice occurred at 4:20 a.m. and right on cue much of the region now has a fresh snow cover and this with a very cold air mass inbound. This arrives today behind the departing low pressure area. A disturbance can create a few snow showers in the region today, and some ocean-effect snow showers can visit Cape Cod both today and Sunday, but overall it’ll be a generally dry weekend with well below normal temperatures. High pressure builds in for a more tranquil but still quite cold day on Monday. A weak low pressure area makes its way through the region early to midday Tuesday with some light snowfall likely. Behind this it remains chilly and a few ocean effect snow showers may be around eastern areas on Christmas Day.

TODAY: Variably cloudy. Chance of snow showers. Temperatures fall slowly to 22-29. Wind N increasing to 10-20 MPH, higher gusts this afternoon.

TONIGHT: Partly cloudy. Additional snow showers possible Cape Cod. Lows 11-18. Wind N 5-15 MPH.

SUNDAY: Mostly sunny except partly cloudy with possible snow showers Outer Cape Cod. Highs Highs 22-29. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 10-17. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Highs 24-31. Wind variable up to 10 MPH.

MONDAY NIGHT: Clouding up. Lows 15-22. Wind variable under 10 MPH.

TUESDAY (CHRISTMAS EVE): Mostly cloudy. Chance of light snow or snow showers. Highs 27-34. Wind variable up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind N 5-15 MPH.

WEDNESDAY (CHRISTMAS DAY): Partly sunny. Chance of light snow showers in eastern areas. Highs 30-37. Wind NE 5-15 MPH.

DAYS 6-10 (DECEMBER 26-30)

High pressure will become the dominant force in our weather holding off unsettled weather producing systems. The temperature moderation will be held in check – maybe back to about normal.

DAYS 11-15 (DECEMBER 31 – JANUARY 4)

Low pressure may bring some precipitation right around mid period (the first or second day of the new year). No temperatures extremes indicated through mid period. Significant cold may arrive by late in the period.

DAYS 1-5 (DECEMBER 20-24)

The coldest air mass of the season so far is on the way. Before it gets here, a minor winter weather event takes place today into tonight with an east to northeast air flow off the ocean around a storm system well offshore to our southeast, eventually tracking into the waters well to our east. This will help pull down cold air as we go through today. Ocean-effect precipitation is underway and will initially be in the form of either rain, sleet, or snow showers (rain showers most likely closer to the coast of the South Shore and Cape Cod), becoming snow showers for all with time. Additionally, expansion and development of the synoptic precipitation area will deliver some steadier snowfall mainly from the I-95 belt eastward, with lighter and somewhat more spotty snow extending further west. Out on Cape Cod, the warmer ocean water will impact the ability of snow to accumulate, so that reason there and the lighter precipitation amounts to the west will be the reason I’m going for under 1 inch of snow in those areas, with a general 1 to 3 inch snowfall elsewhere. The “higher” amounts of that range will occur where both ocean-effect and synoptic snow are maximized, and I cannot rule out a spot amount above 3 inches. This weekend will feature well below normal temperatures – the coldest air of the season so far. We welcome winter with the occurrence of the solstice at 4:20 a.m. Saturday, and that day will be quite breezy with the potential for scattered snow showers as an upper level disturbance moves through. Ocean enhancement of snow showers is possible over Cape Cod. The wind will slacken somewhat for Sunday and dry weather is expected except for the possibility of a few more ocean effect snow showers for the outer portion of Cape Cod. High pressure will provide “halcyon” weather for Monday – bright, dry, cold. A weak clipper low pressure system arrives via the Great Lakes Tuesday (Christmas Eve) with some light snow or snow showers possible. More about this potential in upcoming posts.

TODAY: Cloudy. Ocean-effect snow showers except snow, sleet, or rain showers at first MA South Shore to Cape Cod. Steadier light snow except rain or snow at first Cape Cod later in the day. Highs 30-37 except 35-42 Cape Cod, but a gradual temperature fall begins during the afternoon. Wind E to NE increasing to 5-15 MPH except 10-20 MPH Cape Cod.

TONIGHT: Cloudy. Snow likely, except rain/mix parts of Cape Cod. Snow accumulations 1 to 3 inches except under 1 inch west of I-495 and over Cape Cod. Lows 25-32 except slightly colder well north and west and slightly milder Cape Cod. Wind NE 10-20 MPH coast, 5-15 MPH inland.

SATURDAY: Variably cloudy. Snow showers likely. Temperatures slowly fall to 22-29. Wind N 10-20 MPH, higher gusts. Wind chill readings often under 20.

SATURDAY NIGHT: Partly cloudy. Additional snow showers possible Cape Cod. Lows 11-18. Wind N 5-15 MPH.

SUNDAY: Mostly sunny except partly cloudy with possible snow showers Outer Cape Cod. Highs Highs 22-29. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 10-17. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Highs 24-31. Wind variable up to 10 MPH.

MONDAY NIGHT: Clouding up. Lows 15-22. Wind variable under 10 MPH.

TUESDAY (CHRISTMAS EVE): Mostly cloudy. Chance of light snow or snow showers. Highs 27-34. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 25-29)

High pressure will become the dominant force in our weather holding off unsettled weather producing systems. Temperatures moderate to above normal, but not to any extreme.

DAYS 11-15 (DECEMBER 30– JANUARY 3)

Pacific-dominated air flow brings milder weather but minor precipitation threats as end 2024 and start 2025, but a stronger cold front may return Canadian cold to our region before the end of the period.

DAYS 1-5 (DECEMBER 19-23)

The rain is gone, the mild air has made its exit, colder air is on the way, and there’s snow on the way for most of the region. First, the wave of low pressure that brought a brief but decent slug of rain to the region has exited to the east and we’re in for a fair weather day with a sun/cloud mix. This morning, some temperatures away from the immediate coast and urban areas have fallen close enough to freezing so that lingering wet ground may have converted to black ice on some surfaces, so use caution if heading out early until the temperature can rise sufficiently to eliminate that hazard. Otherwise – a nice day today! But changes come quickly. On Friday, low pressure organized off the Mid Atlantic Coast as high pressure filters cold air in from the north. The low pressure area will pass close enough to southeastern New England Friday night to throw its precipitation shield across much of the region. This will result in a period of accumulating snow, which will be least well northwest of Boston due to further distance and lighter precipitation amounts. A mix with rain over Cape Cod will be a limiting factor there. Between these areas, a general 1 to 3 inches snowfall appears quite probable. I can’t rule out enough synoptic “boosting” and/or ocean enhancement to produce a few pockets above 3 inches. A more definite call on that will appear in tomorrow’s update. As low pressure pulls away it’ll pull in an arctic air mass for the weekend. Saturday can see additional snow showers as a disturbance at high levels drifts through. This day will also be rather breeze behind the departing low pressure area. High pressure will bring more tranquil weather Sunday, which continues Monday as well. The winter solstice occurs at 4:20 a.m. Saturday.

TODAY: Sun/cloud mix. Highs 38-45. Wind N 5-15 MPH.

TONIGHT: Mostly clear. Lows 21-28. Wind N 5-15 MPH.

FRIDAY: Increasing clouds. A few snow flurries possible NH Seacoast and eastern MA coast in the afternoon, except very light rain/snow showers South Shore to Cape Cod. Highs 35-42. Wind N to NE 5-15 MPH.

FRIDAY NIGHT: Cloudy. Snow likely, except rain/mix parts of Cape Cod. Snow accumulations 1 to 3 inches except under 1 inch west of I-495 and over Cape Cod. Lows 25-32 except slightly colder well north and west and slightly milder Cape Cod. Wind NE 10-20 MPH coast, 5-15 MPH inland.

SATURDAY: Variably cloudy. Snow showers likely. Temperatures slowly fall to 22-29. Wind N 10-20 MPH, higher gusts. Wind chill readings often under 20.

SATURDAY NIGHT: Partly cloudy. Lows 11-18. Wind N 5-15 MPH.

SUNDAY: Mostly sunny. Highs Highs 22-29. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 10-17. Wind variable up to 10 MPH.

MONDAY: Mostly sunny. Highs 24-31. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 24-28)

A weak low pressure area from the west can bring some light snow or snow showers (rain or snow showers South Coast) early to mid period, followed by fair weather later in the period. Temperatures undergo gradual moderation.

DAYS 11-15 (DECEMBER 29 – JANUARY 2)

Pacific-dominated air flow brings milder weather but minor precipitation threats as we wrap up 2024 and welcome 2025.
