A Rainy Day Is Expected On Sunday Across Western & Central Mass (Posted Late Saturday Morning 4/18/2026)

For This Afternoon: An area of low pressure is expected to remain positioned offshore of the New England coast throughout this afternoon. This will lead to a chilly easterly wind to be in place.

Lots of clouds can be expected throughout this afternoon. Temperatures will range from the middle 50s across Central Mass to the upper 50s to near 60 Degrees across Western Mass. Winds will be East at around 10 mph.

Tonight: Cloudy skies are expected throughout tonight with low temperatures between 40 and 45 Degrees. Winds will be Southeast at 5 to 10 mph.

Sunday: A strong cold front is expected to push across the entire area during the morning into the early afternoon hours. This front will not only bring a rainy day to all of Western and Central Mass, but it will also cause temperatures to fall during the afternoon leading the rain to mix with some snow in the Berkshires and the Worcester Hills during Sunday afternoon.

Widespread showers are expected to overspread all of Western and Central Mass by about mid-morning Sunday. These widespread showers are expected to continue through late Sunday morning and through Sunday afternoon. Some snow is expected to mix in with the rain showers across the Berkshires and across the Worcester Hills during Sunday afternoon. Even though you may see snow falling during Sunday afternoon if you’re located north of the Mass Pike, it is very likely not to accumulate & just melt on contact.

Temperatures on Sunday will start out in the mid to upper 40s during the morning, but will fall into the upper 30s to near 40 Degrees during the afternoon. Winds on Sunday will be West to Northwest at 10 to 20 mph.

Monday: Marathon Monday looks windy and chilly under a mixture of sunshine and clouds. This means that those of you that are heading to either the Boston Marathon or the very early Red Sox game will need to bundle up.

High temperatures Monday will be between 45 and 50 Degrees. Winds will be West to Northwest at 10 to 20 mph with gusts to 30 mph.

Tuesday: Lots of sunshine can be expected on Tuesday with high temperatures near 50 Degrees.

Wednesday Through Friday: Some scattered rain showers will start the day on Wednesday with increasing sunshine expected by Wednesday afternoon. High temperatures Wednesday will be near 55 Degrees.

Thursday looks sunny with high temperatures between 55 and 60 Degrees.

Friday is expected to be sunny with high temperatures near 60 Degrees.

A Few Showers & Thunderstorms Look Possible This Evening Across Western & Central Mass

For This Afternoon: A backdoor cold front seems to be lingering across Eastern Mass into eastern parts of Worcester County. It is possible that this front may try to back southwestward into more of Central Mass during this afternoon, which could knock down temperatures.

Skies during this afternoon will feature clouds mixed with sunshine. Temperatures will range from the mid 70s to near 80 Degrees across Central Mass to near 85 Degrees across Western Mass and especially in the Pioneer Valley. It’s possible that these temperatures may fall back into the upper 60s to low 70s across northern and eastern parts of Worcester County if that backdoor cold front moves through. Winds during this afternoon will be Southwest at 10 to 15 mph.

Tonight: Yet another weather disturbance in the mid-levels of the atmosphere will cross the region during this evening. As this weather disturbance moves through, it’ll bring with it a few showers and thunderstorms to the area during this evening.

At this point, a few showers and thunderstorms may begin affecting the area by around 7-8 pm or so this evening. These showers and thunderstorms will then last until just after midnight tonight. The coverage of the thunderstorm activity looks to be fairly isolated and they should not be strong or severe.

Low temperatures tonight will be near 55 Degrees. Winds will be West to Northwest at 10 to 15 mph.

Friday: A generally cloudy day is expected on Friday. In addition, it is expected that a frontal boundary will gradually make its way across the region during the day Friday. This front is expected to set off some scattered showers during the morning and then maybe a few showers and possible thunderstorms during the mid and late afternoon hours.

High temperatures Friday will be between 70 and 75 Degrees. Winds will be Northwest at 10 to 15 mph in the morning and Northeast at 6 to 12 mph in the afternoon.

This Weekend: We are expected to return to temperatures that are more average for this time of year, especially on Sunday.

Saturday looks cloudy with high temperatures between 65 and 70 Degrees. Winds will be East to Southeast at around 10 mph.

A strong cold front is expected to push through the entire area during the day on Sunday. This means that there will be widespread showers across the entire area during the day on Sunday. Heavy downpours may accompany some of the showers during the day Sunday. High temperatures Sunday will be near 55 Degrees.

As that front pushes offshore, some much colder air will work into the area by Sunday evening. This could lead to the rain to end as some scattered snow showers during Sunday evening. I am not expecting any sort of impacts from any snow showers that do move through as they should only deposit a dusting of snow, at the very most. Low temperatures Sunday night will be near 30 Degrees.

Monday: A windy and chilly day is expected on Monday under partly sunny skies. High temperatures will be between 45 and 50 Degrees. Those of you heading to either the Boston Marathon or the very early Red Sox game will want to bundle up as temperatures will be in the 40s and a northwest wind will gust up to 30 mph at times.

11:30 pm Wednesday Night Weather Update For Western & Central Mass

Radar imagery at the time of this post indicates that thunderstorms have entered far Western Mass and are moving to the east at a forward speed of about 40 mph or so.

It is expected that these thunderstorms, some which may be strong, will traverse all of Western and Central Mass over the next few hours. Heavy downpours, gusty winds, lightning and even some small hail will accompany the stronger thunderstorms.

Based on my calculations, these thunderstorms should reach the middle and lower Pioneer Valley, including the Springfield Metro by just before midnight and then last until about 1:30-2 am or so.

Further east, these thunderstorms will reach the easternmost parts of the Pioneer Valley and the western Worcester Hills by about 12:30 am and last in these areas until about 2:30 am.

Areas from the I-190 corridor through the Worcester Metro and into the I-395 corridor will probably see thunderstorms begin by about 1 am and last until about 3 am or so.

Eastern areas of Worcester County, including Route 146, as well as the 495 corridor may see the thunderstorms begin by about 1:15-1:30 am and last until about 3:30 am.

Again, these thunderstorms will be capable of producing heavy downpours, gusty winds, lightning and small hail.
