Area Forecast Discussion National Weather Service Boston/Norton MA 751 PM EDT Sat May 17 2025
SYNOPSIS
An approaching cold front may bring a few strong to severe thunderstorms across western Massachusetts and northern Connecticut this evening...but the greater threat may stay across northern New England. Any of this activity will weaken as it tries to work into eastern Massachusetts and Rhode Island later this evening.
Otherwise...drier and cooler air works into the region overnight.
Considerable cloudiness is on tap for Sunday and Sunday night with dry weather dominating...but a few passing showers will be possible at times especially north of the Massachusetts turnpike.
Unseasonably cool air is on tap for much of the upcoming work week...especially later Wednesday into Thursday when a late season Nor'easter may bring a cold/windswept rain.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
Key Messages...
* A few severe storms possible across western MA/CT this evening but greater areal coverage/risk across northern New England
* Drier overnight with most of the activity coming to an end by midnight and lows bottoming out in the 50s
Details...
The main concern revolves around the convective threat into this evening. Low clouds were scouring out across western MA/CT as of mid to late this afternoon. This trend will overspread the rest of the region allowing for partial sunshine to develop from west to east in the next few hours.
The partial sunshine developing will allow a modest amount of instability to develop across the interior with MLCapes rising into the 1000-2000 J/KG range by late afternoon/early evening. There also is a fair amount of effective shear on the order of 35 to 45 knots.
At the same time...a relatively strong shortwave is lifting into northern New England. Although we expect a fair amount of instability/shear our region will be on the edge of the stronger forcing. So there is uncertainty on how much convection will be able to develop across our region
However
given the amount of instability expected to develop with the strong shear...any storms that develops in western MA/northern CT will be capable of becoming severe with the main threats being localized damaging wind gusts and hail
This also looks to be a rather late show
mainly after 5 pm across western MA/CT until about 10-11 pm this evening.
So in a nutshell...a few severe thunderstorms are possible across western MA/CT into this evening
However
confidence in areal coverage/intensity is less than in northern New England given more limited forcing.
What ever activity develops should weaken this evening...as it out runs better instability/forcing. So while a rumble or two of thunder may survive onto the I-95 corridor...the severe weather threat appears low in this region.
By midnight...most of this activity will have dissipated as drier air begins to work into the region behind the cold front. Overnight low temps bottom out mainly in the 50s. Low clouds and fog patches should mainly be confined to areas towards the south coast this evening...but improving conditions after midnight as the winds shift to the west behind the cold front.
SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/
Key Messages...
* Partly-mostly cloudy Sun/Sun night with a few passing showers possible especially north of I-90...but dry weather still dominates
* Highs Sun mainly in the upper 60s to the lower 70s with a W breeze
* Lows Sun night upper 40s to the lower 50s and it will be breezy
Sunday and Sunday night...
Anomalous closed upper level low moves across northern New England Sun and gradually slides off the Maine coast Sun night. The result will be a cyclonic westerly flow of air across the region Sun shifting to the northwest Sun night. The cyclonic flow will result in partly to mostly cloudy skies Sun/Sun night...but a few peeks of sunshine will be possible during the daylight hours. While dry weather will dominate...shortwave energy and the associated cold pool aloft may allow a few showers to drop south into our region at times Sun into Sun night. This is especially true to the north of I-90...closer to the shortwave energy in northern New England.
High temps on Sun should mainly be in the upper 60s to the lower 70s with a westerly breeze. A secondary cold front will cross the region Sun night shifting winds to the NW and it will be breezy. In fact...gusts of 25 to 30 mph will be possible especially toward daybreak. Overnight low temps Sun night will bottom out in the upper 40s to the lower 50s.
LONG TERM /MONDAY THROUGH SATURDAY/
Key Messages:
* Dry and seasonable Monday
* Cooling trend returns Tuesday through the rest of the week
* Another system likely brings significant rain and gusty winds to southern New England for the second half of the week
Details...
Northwesterly flow dominates Monday as a low makes its exit offshore towards the Maritimes by Monday night, helping to mitigate daytime temperatures. Monday's highs hover in the high 60s to low 70s. Flow shifts northeasterly for Tuesday on the back end of the low, further cooling temps for the mid-week: Tuesday through Thursday remaining mostly in the 50s and low 60s.
Later this week continues to look highly unsettled, with a late season Nor'Easter tracking up the east coast towards southern New England. This would likely bring significant rainfall and gusty winds sometime Wednesday evening through Friday; however, timing and track still vary greatly in the guidance. The ECMWF and GFS both have the system arriving around the same time on Thursday, but the ECMWF takes a more coastal track while the GFS keeps the system more offshore. The GEM has consistently indicates a later arrival on Friday, with a slightly offshore track. A more coastal track would bring heavier and longer duration rains with gustier winds than a more offshore track. Regardless, can expect the later half of the week to be unsettled and cool with continued broad cyclonic flow and cooler temperatures aloft.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
00z TAF Update....
This evening into tonight...Moderate Confidence.
Main issue will be for scattered showers and thunderstorms across interior MA and extreme northern CT. The activity should weaken as it approaches the BOS-PVD corridor...probably not until after 03z. Not sure if a few rumbles of thunder survive towards the I-95 corridor...but regardless expect a weakening trend. Most of the activity should dissipate after midnight as winds become West at 5 to 15 knots.
Sunday and Sunday night...High Confidence.
A scattered to broken deck of clouds are expected Sun into Sun night...but some marginal MVFR cigs will be possible too. Much of this time will be dry...but a few showers will be possible at times Sun into Sun night. West winds on Sun will shift to the NW Sun Night. Winds will gust to between 20 and 25 knots at times and perhaps up to 30 knots in a few spots very late Sun night.
KBOS TAF...Moderate Confidence. Main concern is for cluster of weakening scattered showers approaching the terminal 00z.
KBDL TAF...Moderate Confidence. Main concern is for a few strong thunderstorms roughly after 20z/21z through 01z/02z.
Outlook /Monday through Thursday/...
Monday: Mainly VFR, with local MVFR possible. Windy with gusts up to 30 kt.
Monday Night: Mainly VFR, with local MVFR possible. Breezy.
Tuesday: Mainly VFR, with areas MVFR possible. Breezy.
Tuesday Night: Mainly VFR, with local MVFR possible.
Wednesday: Mainly VFR, with local IFR possible. Breezy. Chance SHRA.

Thursday: Mainly MVFR, with areas IFR possible. Breezy. SHRA likely.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Tonight through Sunday night...High Confidence.
A cold front will cross the waters later tonight with the main impact being S winds shifting to the W and drier air working into the region. A closed upper level low will track across northern New England Sunday will exit the Maine coast Sun night. Enough of a gradient will result in W wind gusts of 20 to 25 knots shifting to the NW Sun night with gusts increasing to between 25 and 30 knots.
Therefore...we have hoisted small crafts for some of our waters Sun and all of our waters by later Sun night.
Outlook /Monday through Thursday/...
Monday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of seas approaching 5 ft.
Monday Night through Tuesday Night: Winds less than 25 kt.
Areas of seas approaching 5 ft.
Wednesday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
Wednesday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of rain showers, isolated thunderstorms.
Thursday: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 11 ft. Rain showers likely.
