Weekly Outlook: December 22-28, 2025

If you’re dreaming of a White Christmas, you may just get your wish.

The week starts off with high pressure bringing us a breezy and dry and chilly day today, but that won’t last long. Clouds quickly return later today as a fast-moving storm system moves out of the Great Lakes. We’ll see some light snow developing Tuesday morning, continuing through much of the day, ending in the evening. Temperatures may be just mild enough for a mix or change to rain near the South Coast and across the Cape and Islands. While the system may not have much impact on the morning commute, it will impact the evening commute, so keep this in mind. Because it’s a fast-moving storm, and doesn’t have a lot of moisture with it, we’re only expecting 1-3 inches for most spots, a little less where rain mixes in.

High pressure builds in for Christmas Eve and Christmas Day with generally dry and seasonably cold conditions, though we could still see a few snow showers on Christmas Eve, mainly near the coast thanks to an offshore low pressure system. The end of the week and the weekend presents more problems. A frontal boundary will be nearby, separating some rather chilly air to our north from unseasonably warm air to the south. We’re also going to have a low pressure system moving along that boundary toward the region. Where that boundary eventually settles has a HUGE impact on our forecast. Is it mild with rain? Is it colder with a wintry mix or even some moderate to heavy snow? As you might expect, the models are all over the place, and any of these scenarios could be plausible. For now, we’re going to go with the middle ground, but this is a low confidence forecast at this point. Oh, and another system could follow on Sunday with some similar issues. We’ll obviously go into a lot more detail on both the Friday and Sunday potential storms when we publish our Weekend Outlook, which will be on Wednesday this week.

The models all have different ideas for the system on Friday. Images provided by Pivotal Weather.

Monday: Mostly sunny, clouds start to filter in during the afternoon, thickening up late in the day, breezy in the morning. High 28-35.

Monday night: Becoming cloudy. Low 20-27.

Tuesday: Cloudy with light snow developing in the morning, except rain near the South Coast and Cape Cod, tapering off towards evening. High 32-39.

Tuesday night: Any lingering snow or rain showers ending, some clearing possible late at night. Total snow accumulation 1-3 inches for most spots, less than 1″ near the South Coast and Cape Cod. Low 24-31.

Christmas Eve: Intervals of clouds and sun with a few snow showers possible along the coast, partly sunny inland, breezy. High 33-40.

Wednesday night: Clear to partly cloudy during the evening, clouds return overnight. Low 18-25.

Christmas Day: Partly to mostly cloudy. High 36-43.

Thursday night: Mostly cloudy. Low 20-27.

Friday: Cloudy with some snow or rain likely. High 31-38.

Saturday: A few snow showers early, becoming partly sunny. High 29-36.

Sunday: Mostly cloudy, breezy, chance for snow or rain. High 36-43.

Snow Kidding, a White Sunday is on the Way

If you live in the Merrimack Valley, and points north and west, you already saw your first snowstorm of the season a little more than a week ago. The rest of us get that experience Sunday morning.

A complex low pressure system is going to impact much of Southern New England for a good chunk of Sunday, including the Patriots/Bills game in Foxborough. An upper level disturbance is moving across Ontario this evening while a surface low pressure system takes shape over the Mid-Atlantic states. If conditions were a little more favorable, this could become a blockbuster snowstorm, but that won’t be the case here. We’re already seeing a little rain developing across parts of the Mid-Atlantic, including the New York City area, but as the system moves off the Virginia coastline overnight and strengthens colder air will move in, changing the precipitation over to snow. We should see snow spreading across our area a little after midnight, though it will probably be mixed with rain across parts of Cape Cod and the Islands to start. Snow showers and some periods of steady light snow are expected for the rest of the overnight and into Sunday morning. The bulk of the snow will be found south of the Mass Pike, with just some snow showers to the north, though the latest models are showing a little bit more snow to the north of Boston as well, as the system is coming in a little farther north. As the system starts to pull away by midday Sunday we’ll see the snow taper off, and gusty northwest to north winds will develop, ushering colder air in. Some ocean-effect snow may continue across parts of Cape Cod into the late afternoon or evening, but it should wind down at that point.

Snow moves in overnight, and ends Sunday afternoon/evening. Loop provided by WeatherBell.

This storm will not be that big of a deal for most of us, and shouldn’t have too much of an impact on the region, though if you’re heading to and from Foxborough there will be a bit more of an impact. If you’re arriving early to tailgate, expect to do it in the snow. As for the game, the snow should be winding down towards halftime, but for the 2nd half it’ll be windy and turning colder, so plan ahead for that it you’ll be sitting in the stands.

It might looks like this in Foxborough again Sunday morning. Image provided by the New England Patriots.

As for amounts, here’s what we’re thinking:

Central NH: Less than 1″
Southern NH/NH Seacoast/North Shore/Merrimack Valley: Around 1″
MetroWest/Metro Boston/Central MA: 1-2″
Northern RI/Northern portions of Plymouth/Bristol County (North of Route 44): 1-3″
Outer Cape Cod/Nantucket: 2-4″
Southern RI/Southern portions of Plymouth/Bristol County (South of Route 44)/Upper Cape Cod/Martha’s Vineyard: 3-5″

Snowfall amounts will be generally light to borderline moderate. Image provided by Weathermodels.com

You’ll have plenty of time to clean off the driveway after the snow is done, and you’ll want to do that at that point. With temperatures plunging into the teens for much of the region Sunday night, if you wait until Monday morning to clean off the driveway (or your car), it will be a lot more difficult.

Weekly Outlook: December 1 – 7, 2025

That time has arrived. You know what we’re talking about. That S-word is in the forecast for part of the region. You know the one. It’s 4 letters and rhymes with blow.

The week starts off with high pressure giving us a breezy and cool Monday, but clouds move in Monday night, setting up a messy Tuesday. Despite the hype online for the past week, this will NOT be a big deal for a good chunk of the region, though it is the first one this season, so be prepared for lots of people that forgot how to drive in wintry weather (or never knew how to in the first place). That high will be moving off to the east, so while it’ll be chilly to start the day, we won’t have a lot of cold air in place for much of the storm. An upper-level disturbance will be moving in from the Great Lakes while low pressure develops off the Carolinas heading northeastward. These two won’t join forces until they are well past us, so a blockbuster snowstorm is not expected. In fact, this one will be moving fairly quickly, likely in and out in about 12 hours. We’ll see precipitation developing near or just after the morning rush hour. Temperatures should be cold enough for it to start as snow for most of the region, except for Southeastern Massachusetts, the Cape, and Islands. However, with the ocean still relatively mild (water temperatures are in the 40s to lower 50s), a quick change to rain is expected south and east of Interstate 95. How far inland that rain/snow line gets will be determined by the exact track that the developing coastal storm takes, but that is still a bit of a question mark at this point. Right now, we’re expecting the changeover to likely get as far inland as Interstate 495, but that is highly uncertain. Precipitation will fall moderate to heavy at times on Tuesday, especially south of Boston, but as the system pulls away from the region later in the day, colder air may allow the rain/snow line to quickly move back toward the coast, with much of the region possibly ending as some snow before midnight, except possibly the Cape and Islands. So, how much are we expecting?

Cape Cod/Islands: Rain
Southeastern MA/RI (South and east of I-95): A coating.
Boston-Providence (I-95 corridor): Less than 1″
Northern RI/MetroWest/North Shore: 1-3″
Merrimack Valley: 2-4″
Southern NH/NH Seacoast: 3-6″
Worcester Hills/Monadnocks/Central NH: 4-8″ (possibly 10″ in spots, especially in the higher elevations)

Once the system pulls away we turn drier and chilly for Wednesday as high pressure builds in. Another cold front moves through on Thursday, with a few snow showers or squalls likely accompanying it. Friday looks to be another dry and cold day as high pressure builds back in. The weekend looks unsettled at this point, but nothing significant. Another system will pass by to the south Saturday morning and afternoon with some snow showers inland and rain showers along the coast. At this point, any accumulations look to be light, but that can obviously change, so we’ll keep an eye on it as the week goes on. Another Alberta Clipper quickly follows for later on Sunday. For now, this one looks to be just a few rain showers, possibly snow or a wintry mix well inland, but again, a lot can change between now and then.
