Area Forecast Discussion
National Weather Service Boston/Norton MA
230 AM EST Wed Dec 10 2025

.SYNOPSIS...

Approaching low pressure allows mainly rain to overspread the
region from west to east during the afternoon/early evening
hours with any snow confined to the highest terrain of the 
Berkshires and northern Worcester Hills. A cold front crosses 
the region later tonight...bringing mainly dry but windy and 
much colder weather Thursday into Thursday night. Wind Chills
will be dropping to between 0 and 10 above Thursday night. It 
will still be blustery and chilly Friday with winds finally 
diminishing Saturday...but temperatures still remaining a bit 
below normal. The risk for a period of snow has decreased some 
Saturday night into Sunday...but this is not set in stone. 
Another shot of arctic air with well below normal temperatures 
will follow later Sunday into early next week. 

&&

.NEAR TERM /THROUGH TODAY/...

Key Messages: 

* Rain overspreads the region from west to east this afternoon
  perhaps not reaching I-95 until this evening

* Any snow this afternoon and evening will be confined to the 
  highest terrain of the Berks/Worcester Hills

Today... 

Warm advection and gusty southerly winds bring 850mb temps 
above 0C across much of the region this afternoon. Expecting 
mild surface temperatures in the 40s to perhaps near 50 across 
southeastern MA and RI today. Areas across western/north central 
MA will be chillier with highs mainly in the 30s. Rain should 
overspread the region this afternoon into this evening from 
west to east. It may not even reach the I-95 corridor until this
evening. Mainly expecting rain with any snow confined the 
higher elevations of The Berkshires and northern Worcester 
Hills. Accumulations will be minor, but may approach 1-2 inches 
on the east slopes of The Berks. 

&&

.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...

Key Messages...

* Lingering rain /highest terrain snow/ winds down later this 
  evening with drier but blustery weather following overnight

* Quite windy and cold Thursday with steady or slowly falling
  temperatures into the 20s and lower 30s by mid-late afternoon

Tonight...

A cold front crosses the region later tonight bringing and end
to the rain /very high terrain snow/ this evening. This will be
followed by a brisk west/northwest wind and temperatures 
dipping back down into the upper 20s/low 30s by Thursday 
morning.

Thursday... 

Cold day ahead for Thursday behind the cold front. Guidance shows 
strong cold air advection with 850mb temps falling near -15C by the 
evening. Thursday's high temperatures will occur around midnight 
before the column quickly cools and temps fall back below freezing 
Thursday morning. For most of us, daytime temperatures will struggle 
to warm by even a couple of degrees, and they may even cool 
throughout the day in the higher terrain.

Bigger weather story Thursday will be increasing winds behind a 
deepening area of low pressure over southern Quebec. BUFKIT soundings 
show a deepening mixed layer throughout the day with a LLJ 
strengthening to 45-55 kts at the top of the mixed layer. Mid and 
low-level winds of this magnitude will translate to gusts between 35 
and 45 mph for most locations with the chance for occasional gusts 
up to 50 mph in the higher terrain. Future forecast updates may 
include an upgrade to a wind advisory for much of the region if the 
low level jet trends stronger in guidance. Biggest impact from the 
winds will be wind chills falling from the teens to the 20s early in 
the afternoon to as low as the single digits above zero in the 
terrain to the mid/upper teens above zero for the remainder of 
Southern New England, including the Cape and Islands. Finally, high 
res guidance is showing the chance for isolated snow showers and 
flurries associated with lake effect snow streamers Thursday 
afternoon. The best chance for this activity would likely be in the 
Berkshires and perhaps into central Mass. 

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

Key Messages...

* Quite Windy & cold Thu night...Wind Chills between 0 and 10 above
* Dry, but blustery and cold Fri...Highs upper 20s to the middle 30s
* Mainly dry during the day Sat with highs generally in the 30s
* Snow risk has decreased some Sat night-Sun...but not set in stone
* Another shot of arctic air late Sun-Mon...Highs Mon only in the 20s
 
Details...

Thursday night...

It will remain quite windy Thu night given a strong WNW 850 mb jet 
on the order of 50-60 knots. This coupled with 850T near -15C will 
yield excellent mixing. We expect northwest wind gusts of 35-50 mph 
and may need Wind Headlines well into the overnight hours. The 
strong winds will keep temps from completely bottoming out...but the 
CAA will result in lows still in the teens with downtown 
Boston/Providence and Cape in the 20-25 degree range. More 
importantly the strong winds will result in Wind Chills dropping to 
between 0 and 10 above and even briefly below zero in the highest 
terrain!

Dry weather will generally prevail Thu night...but given cold strong 
westerly flow some remnant Lake effect moisture may result in a 
brief spot snow shower/flurry or two. 

Friday...

Strong low pressure shifts north of the Canadian Maritimes on 
Friday. Still enough of a pressure gradient though to result in 
blustery conditions. While winds will not be a strong as what we are 
expecting tomorrow...still expect westerly wind gusts of 25 to 35 
mph. Highs on Friday will remain cold...generally in the upper 20s 
across the high terrain to the lower-middle 30s elsewhere.

This Weekend...

A ridge of high pressure to our south will slowly move east on 
Saturday. At the same time...another piece of strong shortwave 
energy will be dropping southeastward into the Great Lakes. The 00z 
models indicate the trough axis further east than guidance over the 
past 12-24 hours. This tends to suppress the low pressure further 
south in much of the guidance compared to yesterday/s runs. So the 
overall snow threat in the Sat night to Sun has decreased...but this 
is not set in stone. There are still individual ensemble members 
especially from the CMC guidance that track the low pressure system 
further north. The models seem to be struggling with 
amplitude/timing of northern stream energy which will have a 
significant impact on the track of this wave of low pressure. So 
while odds for accumulating snow have decreased some Sat night-
Sun...still too early to rule out a trend back north. Will need 
another 36-48 hours to have more confidence in the eventual outcome. 

High temps will mainly be in the 30s this weekend with the colder 
day on Sunday. In fact...temperatures may be falling during the day 
Sunday with a gusty NW developing behind the next arctic cold front.

Monday and Tuesday...

Another short of arctic air impacts the region for the start of the 
next work week. While mainly dry weather is expected...high temps 
will be well below normal. Highs on Monday will likely only be in 
the 20s. May see a bit of a modification by Tuesday...but still 
expect highs only in the upper 20s to the middle 30s.

front with sustained winds around 15 knots. 

Thursday...High Confidence
