1 To 3 Inches Of Snow Accumulation Is Expected On Tuesday Across Western & Central Mass (Issued: Early Sunday Afternoon 12/21/2025)

For The Rest Of This Afternoon: It will continue to be windy throughout the rest of this afternoon under a mixture of sunshine and clouds. Temperatures will remain in the low to mid 30s. Winds will be West to Northwest at 15 to 25 mph with gusts to 35-40 mph.

Tonight: A windy and cold night is expected across the entire area under clear skies. Low temperatures will be near 15 Degrees. Winds will be West to Northwest at 15 to 20 mph with gusts to 30-35 mph.

Monday: Monday looks to be a sunny to partly sunny day. High temperatures will be near 30 Degrees. Winds will be West to Northwest at 10 to 20 mph with gusts to 30 mph.

1 To 3 Inches Of Snow Accumulation Is Expected On Tuesday: A warm front is expected to affect the entire area during the day on Tuesday. Western and Central Mass is expected to remain on the colder side of this warm front and because of this, light to moderate snow can be expected throughout much of the day on Tuesday.

Light to occasionally moderate snow is expected to overspread Western Mass by just after sunrise Tuesday morning and then begin across Central Mass by mid-morning Tuesday. The light to occasionally moderate snow looks to then continue through all of late Tuesday morning and all of Tuesday afternoon. The snow is then expected to come to an end by early Tuesday evening.

All-in-all, this is looking like a widespread 1 to 3 inch snowfall across all of Western and Central Mass.

For those of you traveling on Tuesday or if you are going to be out and about on Tuesday, be aware that untreated roads and other surfaces will likely be slick as the snow will be wet in consistency leading to greasy surfaces. So, be careful out there on Tuesday.

Additionally, Tuesday’s snowfall will guarantee a white Christmas for this year across all of Western and Central Mass as the snow that we receive on Tuesday will stick around through Christmas Eve and Christmas Day.

High temperatures Tuesday will be in the low 30s. Winds will be West at 5 to 10 mph in the morning and East at 5 to 10 mph in the afternoon.

Christmas Eve & Christmas Day: A windy Christmas Eve is expected under partly sunny skies. High temperatures will be around 35 Degrees.

Christmas Day looks cloudy with high temperatures near 40 Degrees.

Friday & Saturday: The weather forecast for late this coming week has a very high degree of uncertainty, both for weather and temperatures. A frontal boundary is expected to set up somewhere near the northeastern US and Mid-Atlantic states. Where this boundary sets up is going to be crucial in determining both temperatures and precipitation type on Friday.

If this boundary sets up to our south over the Mid-Atlantic states, it would lead to temperatures in the upper 20s to low 30s on Friday with snow or ice. On the other hand, should this boundary sets up over our area or just to our north, it would lead to temperatures to be in the mid 40s to low 50s on Friday with rain.

For now, I’m going with an unsettled day on Friday with mixed precipitation changing to rain and high temperatures around 40 Degrees. Be aware though that, significant changes in the forecast may be needed depending on where that frontal boundary sets up in relation to our area.

Saturday looks sunny with high temperatures between 30 and 35 Degrees.

Potential Accumulating Snow On Tuesday Would Guarantee A White Christmas Across Western & Central Mass

For Tonight: A cold front is expected to approach the area from the west throughout tonight.

Varying amounts of cloud cover can be expected throughout tonight. Low temperatures will be near 25 Degrees. Winds will be Southwest at 10 to 20 mph with gusts to 30 mph.

Sunday Through Monday: That cold front is expected to push through the region during the late morning and afternoon hours of Sunday before it moves offshore on Sunday night. A high pressure system will very briefly control the weather during the day on Monday.

Sunday looks to feature a mixture of sunshine and clouds during the morning into the first half of the afternoon. Skies will then become clear to partly cloudy by late afternoon. High temperatures will be near 40 Degrees. Winds will be West at 15 to 25 mph with gusts to 35 mph.

Clear to partly cloudy skies are expected on Sunday night with low temperatures near 15 Degrees. Winds will be West to Northwest at 15 to 25 mph with gusts to 30-35 mph.

Monday looks to be a sunny to partly sunny day. High temperatures will be near 30 Degrees. Winds will be West at 10 to 20 mph with gusts to 30 mph.

Accumulating Snow Looks Pretty Likely On Tuesday: A warm front is expected to approach the area from the southwest during the day on Tuesday. As it does so, it’ll produce snow across the entire area during the day on Tuesday. Additionally, there is the possibility that an area of low pressure may form along this frontal boundary as it reaches the Gulf of Maine on Tuesday night. The development of this low pressure system could prolong how long it snows across parts of the area.

Light to possibly moderate snow looks to overspread the entire area around or just after sunrise Tuesday morning. The light to moderate snow looks to then continue throughout much of the day on Tuesday before it comes to an end during late Tuesday afternoon and early Tuesday evening.

Current indications seem to be pointing towards snowfall amounts of 1 to 3 inches to occur across the entire area during the day on Tuesday. I do want to mention that should we see a quicker development of that low pressure system, it could extend how long it snows across the entire area through Tuesday night & should this occur, it would lead to higher snow amounts (upwards of 3 to 6 inches??). I want to emphasize that this is something that I’m not forecasting right now & instead, I think that it’s more likely we see something like a 1 to 3 inch snowfall.

All-in-all, it looks like Tuesday’s expected snow will guarantee a white Christmas across the entire area this year.

Temperatures during the day on Tuesday will be in the low 30s.

Christmas Eve & Christmas Day: A mixture of sunshine and clouds can be expected during Christmas Eve with high temperatures near 35 Degrees.

Christmas Day is looking cloudy with high temperatures between 35 and 40 Degrees.

Friday Evening Weather Update For Western & Central Mass

Temperatures have fallen into the upper 30s to low 40s at the time of this post and are expected to continue quickly falling towards freezing over the next couple of hours.

Additionally, rain has changed to snow across the Berkshires and the western Hilltowns of Western Mass while rain continues everywhere else. It is anticipated that rain will change to a period of snow within the next hour or so across much of the region, even down into the valley locations of Western Mass. Any snow will last for an hour or two and should be done everywhere by 9-10 pm.

Snow accumulations from any snow over the next few hours should range from a dusting in the Pioneer Valley of Western Mass to perhaps around one inch or so in the Worcester Hills, the hilltowns of Western Mass and the Berkshires.

The combination of rain changing to snow and temperatures falling to below freezing will lead to icy spots on roads, parking lots, sidewalks, driveways, stairs and other surfaces. So, use caution if you are out and about over the next few hours and be aware that there will be areas where things may be slick.

Finally, it'll continue to be windy throughout much of tonight with West winds of 20 to 30 mph with gusts to 40-50 mph expected.
