Area Forecast Discussion
National Weather Service Boston/Norton MA
659 PM EDT Fri Mar 21 2025

SYNOPSIS
Dry and mild Saturday with some scattered showers possible later
Saturday afternoon. A cold front moves through Saturday night
bringing windy and cooler conditions through Sunday. Another
round of precipitation is expected early Monday into early
Tuesday with mainly rain, but perhaps a period of wet light snow
across parts of the interior early Monday morning. Another
system moves through on Wednesday bringing back precipitation
chances.

.NEAR TERM /THROUGH SATURDAY/...
Key Messages...

* Winds gusting 30 to 40 mph into this evening.

Winds briefly diminish late tonight as low pressure continues to
move offshore. Dry weather continues. The mixing from the wind
should preclude stronger radiational cooling, but still near
normal for late March. Clearing skies, so no real weather
issues.

.SHORT TERM /SATURDAY NIGHT/...
Key Messages...

* Mainly dry & milder Sat with highs well up into the 50s.

* Dry except for a brief spot shower or two across the interior.

Winds become southwest and gusty once again ahead of a cold
front that crosses southern New England during the afternoon and
evening. Precipitable water is rather low, around one half
inch. Thus, while there may be a few spot showers, not expecting
much rainfall region-wide. This front should move offshore by
late evening, with high pressure following in its wake.

Above normal temperatures expected tomorrow, then trending near
to slightly below normal tomorrow night.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Key Messages:

* Rain on tap for Mon beginning as a brief period of wet snow
  mainly across portions of the interior

* Potential for another system Wednesday bringing next chance
  for precipitation. Uncertainty in details.

* Cooler than average temperatures next week w/ a trough over
  the eastern CONUS.

Sunday:

Cooler airmass moves in behind Saturday`s dry cold frontal
passage. Windy conditions possible w/ gusts between 30 and 40
mph during the first half of the day. Winds relax as a ridge of
high pressure crests over the region Sunday afternoon and
evening.

Sunday Night - Wednesday:

There continues to be good agreement with model guidance
depicting an upper level trough and associated low pressure
moving across the Great Lakes region and toward New England
overnight Sunday through Monday. New England will be firmly in
left exit region of the upper jet. Closer to the surface, a warm
front will pair with a plume of anomalous moisture to bring
another round of precipitation to the region. Precipitation
chances gradually increase early Monday morning from west to
east, continuing through late Monday night/early Tuesday.

Some uncertainty exists with respect to the storm track/timing
and cold air availability ahead of the system. This will play
into the potential for light wet snow at the onset of the system
that ensembles are signaling at. Ensembles show probabilities
for a trace to light snow accumulation across the interior,
mainly MA. Ensembles show generally a 20-60% chance for seeing
over an 1" north of the Mass Pike. The higher probabilities
(60%+) are confined to the higher elevations such as the
Berkshires and northern border of central MA. This period of
snow will be likely short-lived as the vertical column warms
into mid-morning Monday as the warm front progresses north.
There is a low chance for some flakes to mix in further east,
but will depend on the timing of the system with the cold air.
The rest will be rain that continues through Monday night.

Midweek:

Conditions trend drier Tuesday behind Monday`s system with highs
in the 40s and low 50s. Ensemble guidance shows another
shortwave trough moving across mid-week that could bring some
precipitation to southern New England. Details still need to be
ironed out especially with the track which will impact QPF and
precipitation chances.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

High confidence.

VFR through tomorrow night for most of southern New England.
Diminishing NW winds late tonight. Winds becoming SW and gusty
once again ahead of a cold front. Areas MVFR with the passage of
this cold front along with spot showers.

Forecaster Confidence Levels:

Medium - 30 to 60 percent.
High - greater than 60 percent.

Low pressure moves farther east tonight. Gusty winds diminish
late tonight. Rough seas will take longer to subside across the
outer coastal waters, but should eventually do so in the
afternoon. Winds turn SW ahead of a cold front that should cross
the waters Saturday night. Small Craft Advisories posted for all
waters into tonight.

Outlook /Sunday through Wednesday/...

Sunday: Low risk for Small Craft Advisory winds with gusts up
to 30 kt. Local rough seas.
