DAYS 1-5 (JANUARY 11-15)

While a strengthening storm passes well to our south today and misses the region, it has a weaker upper level cousin with weak surface trough to its north, and that is passing through our region giving us a light snow event. However with the help of a developing mesoscale low and mini version of a NORLUN trough (a type of inverted trough that extends out the back side of the low and pivots around it), the snowfall can be enhanced somewhat in areas along the coast and north of Boston, before the system pulls away into the Gulf of Maine by evening. After that, high pressure to our southwest will nose into New England and provide fair, seasonably chilly weather for our region Sunday and Monday. Tuesday, low pressure will pass to our north, sending a cold front through. This may produce a few snow showers, and also kick up the wind with a slightly colder air mass arriving as we head toward the middle of the week.

TODAY: Cloudy. Periods of snow, tapering off in the afternoon but lingering longest north of Boston and along the eastern coastal areas. General accumulation of 1 inch or less south of I-90, 1-3 inches north of I-90 except 3-5 inches in portions of northern MA,southern NH, and some eastern coastal areas. Highs 25-32. Wind N to NE up to 10 MPH.

TONIGHT: Clearing. Lows 14-21. Wind N to NW 5-15 MPH.

SUNDAY: Mosttly sunny. Highs 30-37. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 15-22. Wind W 5-15 MPH.

MONDAY: Partly sunny. Highs 32-39. Wind W 5-15 MPH.

MONDAY NIGHT / TUESDAY: Variably cloudy. Chance of snow showers. Lows 16-23. Highs 29-36. Wind W increasing to 10-20 MPH, higher gusts.

TUESDAY NIGHT: Clearing. Lows 15-22. Wind NW 10-20 MPH.

WEDNESDAY: Partly cloudy. A passing snow flurry possible. Highs 23-30. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 16-20)

An additional round of snow showers from a disturbance in a cold northwesterly air flow early or mid period, then a snow threat presents itself late in the period as the upper flow shifts to southwest and brings moisture this way from the southern US. Long way to go for details…

DAYS 11-15 (JANUARY 21-25)

A shot of colder air follows a beginning-of-period snow chance, and another snow opportunity may follow around January 24.

DAYS 1-5 (JANUARY 10-14)

The wind and cold ease up today as high pressure moves over the region with fair weather and plenty of sun. A deepening low pressure area will pass off the Mid Atlantic Coast and move well south of New England Saturday, while a weaker system to the north, in the form of upper level low pressure with a weak surface low, will bring our region a period of light snowfall. As this system starts to move offshore late in the day and evening, a narrow lobe of moisture in the form of moderate snow showers can pivot southward and clip the NH Seacoast, far eastern MA, and Cape Cod, with an additional small snowfall accumulation over a shorter period of time, so keep this in mind if you have late day or evening plans that include travel. High pressure to the southwest noses its way into the region with fair, seasonably chilly weather and a breeze – but not too windy – Sunday and Monday. Tuesday, a low pressure system from Canada will pass to our north and send a trough and cold front into the region with a snow shower chance, also introducing a surge of colder air with more wind.

TODAY: Sunshine – some high clouds show up during the afternoon hours. Highs 31-38. Wind W 5-15 MPH.

TONIGHT: Increasing clouds. Lows 15-22. Wind variable up to 10 MPH.

SATURDAY: Cloudy. A period of snow morning-midday, accumulating 1/2 to 1 1/2 inch. Highs 25-32. Wind variable to N up to 10 MPH.

SATURDAY NIGHT: Cloudy early with additional snow showers favoring eastern coastal areas with an additional 1/2 inch to 1 inch possible. Clearing overnight. Lows 14-21. Wind N to NW 5-15 MPH.

SUNDAY: Mosttly sunny. Highs 30-37. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 15-22. Wind W 5-15 MPH.

MONDAY: Partly sunny. Highs 32-39. Wind W 5-15 MPH.

MONDAY NIGHT / TUESDAY: Variably cloudy. Chance of snow showers. Lows 16-24. Highs 29-36. Wind W to NW 10-20 MPH, higher gusts.

DAYS 6-10 (JANUARY 15-19)

A stretch of mainly dry weather – maybe a few snow showers from a passing disturbance mid period. Temperatures generally below normal.

DAYS 11-15 (JANUARY 20-24)

An early period snow/mix threat and another possible late in the period with indications of a more active pattern and continued below normal temperatures. A significant shot of Arctic air is possible mid period.

DAYS 1-5 (JANUARY 9-13)

The large low pressure area in Atlantic Canada continues to drive cold air into our region on a gusty wind. A disturbance moving through from north to south will cause some snow showers this morning and midday which can result in minor accumulation of snow in some areas, otherwise we stay mainly dry through Friday. Low pressure passes well south of New England Saturday but patches of light snowfall are expected here from a disturbance moving through north of that low from the west. A narrow area of high pressure will bring fair, cold weather for Sunday before another low approaches from the west on Monday with an increase in clouds.

TODAY: Partly sunny. Scattered snow showers likely with minor spotty accumulation. Highs 23-30. Wind N to NW 15-30 MPH with gusts 35-45 MPH. Wind chill below 20 often, below 15 at times.

TONIGHT: Partly cloudy. Lows 11-18. Wind NW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 27-34. Wind NW 10-20 MPH.

FRIDAY NIGHT: Increasing clouds. Lows 13-20. Wind N up to 10 MPH.

SATURDAY: Cloudy. Periods of light snow – accumulation up to 1 inch possible. Highs 23-30. Wind N up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 14-21. Wind NW 5-15 MPH.

SUNDAY: Partly sunny. Highs 28-35. Wind NW 5-15 MPH.

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

MONDAY: Increasing clouds. Highs 27-34. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 14-18)

A disturbance / weak low brings a snow shower chance January 14, otherwise a dry and cold pattern much of next week.

DAYS 11-15 (JANUARY 19-23)

Early to mid period snow potential, followed by dry weather. Temperatures below normal, and may include a significant shot of arctic air.

DAYS 1-5 (JANUARY 8-12)

The cold, mainly dry, windy weather will continue for a few more days thanks to the large low pressure circulation that has taken up residence, for now, in Atlantic Canada. This low also continues to prevent eastward-moving storms from making their way up the coast, and will do so again, sending another one out to our south early in the weekend, while we just get a touch of light snow from a disturbance to its north that it failed to phase with. Prior to that, I still eye the chance of a batch of snow showers that can coat the ground tomorrow in a few spots and a few flurries that may occur today. Behind the Saturday system, I expect fair weather again for Sunday.

TODAY: Partly sunny. A possible snow shower. Highs 22-29. Wind NW 10-20 MPH, gusts around 30 MPH. Wind chill often under 20.

TONIGHT: Partly cloudy. Isolated snow showers. Lows 10-17. Wind N 5-15 MPH, higher gusts. Wind chill occasional under 10.

THURSDAY: Partly sunny. Scattered snow showers likely with minor spotty accumulation possible. Highs 23-30. Wind NW to N 10-20 MPH, higher gusts. Wind chill below 20 at times.

THURSDAY NIGHT: Partly cloudy. Lows 11-18. Wind NW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 27-34. Wind NW 10-20 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 12-19. Wind NW 5-15 MPH.

SATURDAY: Mostly cloudy. Chance of snow showers. Highs 26-33. Wind variable 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 14-21. Wind NW 5-15 MPH.

SUNDAY: Partly sunny. Highs 28-35. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 13-17)

A disturbance / weak low brings a snow shower chance about January 14, otherwise a dry and cold pattern much of next week.

DAYS 11-15 (JANUARY 18-22)

Mid period snow potential flanked by dry weather. Temperatures generally below normal.

DAYS 1-5 (JANUARY 7-11)

While the media is in a frenzy about computer model runs, I continue to look at the weather situation from an objective scientific point of view, and today’s prognostication will look a lot like the one posted 24 hours prior. The theme for today through midweek is cold, dry, and breezy / windy, on the back side of a large low pressure circulation in Atlantic Canada – part of a large scale blocking pattern that has been steering storms to our south and then collecting their remnants in a giant whirlpool of air to our northeast. This continues, with largely dry weather for our region. While I can’t rule out a passing snow flurry today and Wednesday, a trough coming around the back side of the aforementioned low pressure area enhances the snow shower chance on Thursday, and we’ll have to monitor these for the potential of delivering some minor accumulation to portions of the region. Behind this, a gusty northerly breeze continues Friday, but that day should be absent of snow shower chances. Now to “day 5”, a day that has been overly focused on too far in advance because of computerized atmospheric simulations, some of which have shown an epic snowstorm – and the vast majority of which have not, but have been often ignored in the name of hype, views, and clicks. Well, keeping it real, yes there is a “threat” of a storm system of some kind as we get to the weekend. There will be a storm system coming out of the South and heading for the Mid Atlantic Coast, and another “piece of energy” in the form of a trough swinging our way via the Great Lakes. Both of these are likely to be impacted by the blocking pattern in place, which will have shifted barely enough to allow the Atlantic Canada low to nudge eastward, but not far enough to exert its influence on the southern system, which is more likely than not to begin missing the region to the south, or maybe grazing our region’s southern reaches, during Saturday, while what remains of the northern energy brings us a snow shower threat. Obvious monitoring and refining of this outlook as necessary, and I’ll speak of it as needed in the comments and more thoroughly on tomorrow’s post.

TODAY: Partly cloudy. A passing snow shower possible with potential dustings. Highs 22-29. Wind NW 10-20 MPH, gusts around 30 MPH. Wind chill often under 20.

TONIGHT: Mostly clear to partly cloudy. Lows 10-17. Wind NW 5-15 MPH, gusts above 20 MPH. Wind chill below 10 at times.

WEDNESDAY: Partly sunny. A possible snow shower. Highs 22-29. Wind NW 10-20 MPH, gusts around 30 MPH. Wind chill often under 20.

WEDNESDAY NIGHT: Partly cloudy. Isolated snow showers. Lows 10-17. Wind N 5-15 MPH, higher gusts. Wind chill occasional under 10.

THURSDAY: Partly sunny. Scattered snow showers likely with minor spotty accumulation possible. Highs 23-30. Wind NW 10-20 MPH, higher gusts. Wind chill below 20 at times.

THURSDAY NIGHT: Partly cloudy. Lows 11-18. Wind NW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 27-34. Wind NW 10-20 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 12-19. Wind NW 5-15 MPH.

SATURDAY: Mostly cloudy. Chance of snow showers. Highs 26-33. Wind variable 5-15 MPH.

DAYS 6-10 (JANUARY 12-16)

Clouds and snow showers can linger into the late weekend (January 12), otherwise looks like more dry and cold weather on tap heading into next week – maybe a snow shower threat mid period period with a disturbance in the northwesterly air flow (about January 14).

DAYS 11-15 (JANUARY 17-21)

Mid to late period snow potential but highly uncertain scenario. Temperatures generally below normal.

DAYS 1-5 (JANUARY 6-10)

Low pressure with a storied past (lots of winter weather across the country) passes south of New England today, and while its cloud shield will spend some time over our sky, its snow area will miss to the south, outside of a few stray flakes that may sprinkle themselves over the South Coast region. This moves away tonight and as the low heads into Atlantic Canada to be absorbed by the quasi-stationary low pressure circulation there, it will serve to keep us cold, dry, and windy through midweek, with no more than a few stray snow showers wandering across our winter-dry landscape. Friday, high pressure edges a bit closer and the low in Atlantic Canada slightly loosens its grip, so we’ll have less wind that day, but dry weather again.

TODAY: Early morning bright sky and some sun far eastern areas, and the process of clearing starts toward the end of the day with a nice sunset potential for part of the region, but between generally an overcast sky. Touch of light snow possible South Coast for a brief time. Highs 23-30. Wind N to NW 5-15 MPH.

TONIGHT: Clearing. Lows 11-18. Wind NW 5-15 MPH, higher gusts. Wind chill below 10 at times.

TUESDAY: Partly cloudy. A passing light snow shower possible. Highs 22-29. Wind NW 10-20 MPH, gusts around 30 MPH. Wind chill often under 20.

TUESDAY NIGHT: Mostly clear to partly cloudy. Lows 10-17. Wind NW 5-15 MPH, gusts above 20 MPH. Wind chill below 10 at times.

WEDNESDAY: Partly sunny. A possible snow shower. Highs 22-29. Wind NW 10-20 MPH, gusts around 30 MPH. Wind chill often under 20.

WEDNESDAY NIGHT: Partly cloudy. Isolated snow showers. Lows 10-17. Wind N 5-15 MPH, higher gusts. Wind chill occasional under 10.

THURSDAY: Partly sunny. Scattered snow showers. Highs 23-30. Wind NW 10-20 MPH, higher gusts. Wind chill below 20 at times.

THURSDAY NIGHT: Partly cloudy. Lows 11-18. Wind NW 5-15 MPH.

FRIDAY: Partly cloudy. Highs 30-37. Wind W up to 10 MPH.

DAYS 6-10 (JANUARY 11-15)

Storm passes by to our south during the January 11-12 weekend with highest odds of a miss from it, medium odds of a South Coast graze, and lowest odds of a more widespread impact. Another disturbance going by to the north may produce some light snow or snow showers in the region at some point. Dry, cold weather follows this early next week.

DAYS 11-15 (JANUARY 16-20)

Early to mid period snow potential but highly uncertain scenario. Temperatures generally below normal.

DAYS 1-5 (JANUARY 5-9)

Our cold and dry regime goes on. A westerly air flow continues today, and shifts a bit more northerly tonight into Monday as a low pressure wave going by to our south alters the pressure gradient and resulting air flow. This low will be “close-but-no-cigar” in terms of bringing some snow to the region, passing harmlessly to the south with the maximum impact being a few tiny snowflakes reaching the ground along the immediate South Coast. Behind it, a renewed and more northerly wind will transport more cold into our region from Canada through midweek. It is during this period when some snow showers can migrate down from the north in response to an upper level disturbance moving through.

TODAY: Partly cloudy. Highs 27-34. Wind W 5-15 MPH with gusts over 20 MPH.

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

MONDAY: A cloudy start – thickest clouds South Coast where a touch of very light snow is possible, then thinning and decreasing clouds midday on. Highs 25-32. Wind N to NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 11-18. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 23-30. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 8-15. Wind NW 5-15 MPH.

WEDNESDAY: Partly sunny. A possible snow shower. Highs 24-31. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Isolated snow showers. Lows 10-17. Wind N 5-15 MPH, higher gusts.

THURSDAY: Partly sunny. Scattered snow showers. Highs 22-29. Wind N 10-20 MPH. Wind chill below 20.

DAYS 6-10 (JANUARY 10-14)

Dry to start the period, and again to end it. The January 11-12 weekend bears watching for a potential snow threat as low pressure passes by to the south, but at the moment I lean toward a graze or a near-miss from the system. Temperatures below normal.

DAYS 11-15 (JANUARY 15-19)

Colder than normal with mainly dry weather, but watch for a few snow showers and perhaps one possible snow threat at mid period.

DAYS 1-5 (JANUARY 4-8)

Our pattern remains cold and for the most part dry, but we have a decent westerly air flow allowing some moisture to make its our way via the Great Lakes in the form of occasional cloudiness. Some of these clouds are capable of releasing snow showers, but most of them are just light flurries. This continues this weekend. Monday, a quick-moving low pressure area will pass just south of the region and I do not believe any of its snow shield will make it to New England. After a lighter northerly wind as that low goes by and interrupts the larger scale northwesterly air flow over us, the latter will return Tuesday and Wednesday with more cold and dry weather on tap.

TODAY / TONIGHT / SUNDAY: Partly cloudy. A few snow showers possible. Highs 27-34. Lows 12-19. Wind W 5-15 MPH with gusts over 20 MPH.

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

MONDAY: Decreasing clouds. Highs 25-32. Wind N to NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 11-18. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 23-30. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 8-15. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 24-31. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 8-13)

Cold and dry pattern. Suppressed storm track keeps snow threats to south, but one system may make a close pass around mid period so it’ll be watched for sneakiness.

DAYS 11-15 (JANUARY 14-18)

Cold continues, but storm track also edges closer with a potential storm threat evolving – nothing specific to detail this far in advance.

DAYS 1-5 (JANUARY 3-7)

The theme is cold and dry as we head through the first weekend of 2025 and into the first full week of the new year. A blocking pattern features a large low pressure circulation in Atlantic Canada and high pressure to the west, and New England in a cold northwesterly air flow, and this doesn’t change much at all. I’ve been eyeing the January 6-7 period for many days now to watch a low pressure area passing to our south, and it will definitely do that, and the closest it appears it can get is maybe to send a few snowflakes into the South Coast region Monday, if that. Beyond the opportunity for a passing snow shower wandering our way from around the Great Lakes today and tomorrow, and the aforementioned minor threat to the south Monday, there isn’t anything else to talk about besides dry weather and a cold breeze.

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

TONIGHT: 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 morning-midday with a chance of light snow near the South Coast, then increasing sun. Highs 24-31. Wind N to NW 5-15 MPH.

MONDAY NIGHT: Clear. Lows 11-18. Wind NW 5-15 MPH.

TUESDAY: Sunny. Highs 23-30. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 8-12)

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

DAYS 11-15 (JANUARY 13-17)

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

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.

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.
