Area Forecast Discussion
National Weather Service Boston/Norton MA
723 AM EDT Wed Oct 15 2025
.SYNOPSIS...
Cloudy, cool, and blustery conditions today. An unseasonably
cool airmass brings below normal temps and blustery conditions
Thursday with ocean effect cloud cover, periods of rain showers
and stronger northerly breezes across the eastern Massachusetts
coast. Warming trend for Friday into the weekend before turning
more unsettled as we move into early next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Key Point
* Cool and blustery today
Shortwave trough and cold front drop out of northern New England
today, bringing blustery cool conditions to much of the region.
Highs today will struggle to reach the upper 50s to low 60s due to
cold air advection. Winds increase from the NW this afternoon with
gusts of 20-25mph, which will make it feel like the low to mid 50s.
Not anticipating much sunshine today, as even after the low cloud
cover clears, mid to high-level clouds will filter in with the
shortwave.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Key Point
* Cold and blustery tonight
* Cool and windy Thursday
* Minor splash over coastal flooding possible Thursday afternoon
high tide for north facing beaches.
Temperatures tonight will drop rather quickly into the 40s by 8 pm
and then bottom out in the 30s due to strong cold air advection.
Winds remain blustery overnight with 15-20mph gusts as winds aloft
increase. Strong cold air advection continues into Thursday, and
with 850mb temps holding at -5C, high temps at the surface will only
top out in the low to mid 50s. Thursday should feature more sun
than clouds across the interior, which will help promote boundary
layer mixing and gusty winds of 25-35mph. With the cold air moving
over ocean water temps still in the upper 50s to low 60s, expecting
overcast skies for the Cape and Islands with periods of ocean effect
showers. Winds near and over the waters will be stronger than
across the interior with gusts of 35-40mph. There could be some
very minor splash over coastal flooding during the Thursday
afternoon high tide for north-facing coastlines as offshore waves
increase to 7-10 feet.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Key Messages:
* Dry with a warming trend Fri/Sat. Mid 70s possible Sun.
* Cold front later Sun night and Mon brings a period of rainy
conditions.
Details:
Thursday Night:
Nighttime lows, while still rather chilly in the upper 30s to the
mid 40s, will be kept up some by at least the continued northerly
winds and also coastal cloudiness.
Friday/Saturday:
Transition period in the pattern toward 500 mb height rises and a
warming trend to temps for late in the week into the early weekend.
Sunny and dry with decreasing northerly winds, with highs on Fri in
the lower 60s, and into the mid 60s to perhaps near 70 on Sat
depending on how well we can mix.
Sunday and Monday:
Main forecast challenge in this period is the timing of a strong
cold front which moves through either Sunday or on Monday. This will
affect the timing of rain chances but also on temperatures for both
Sunday and Monday. Leaned toward a slower frontal timing which would
mean warmer temps on Sunday, which were already forecast to be above
normal in the lower 70s, but mid to even upper 70s could be
conceivable given 925 temps around +10C if cloud cover/rain from the
front can hold off. Thinking rain chances increase Sun night into
Mon, leading to a cloudy day Mon with periods of showers and temps
in the 60s.
