Area Forecast Discussion
National Weather Service Gray ME
1258 PM EST Mon Nov 24 2025
.SYNOPSIS...
High pressure builds in from the southwest tonight and shifts
offshore Tuesday. Low pressure developing over the Great Lakes
will send moisture into New England through the day Tuesday with
light rain developing Tuesday night. The mountains and northern
areas likely see a wintry mix before a change to rain
Wednesday. A cold front crosses Wednesday night into Thursday
bringing a cooling trend into the weekend with gusty winds.
&&
.NEAR TERM /THROUGH TONIGHT/...
Stubborn cloud cover in upslope flow and downstream of the
mountains is expected to erode into tonight as high pressure
noses in from the southwest. Winds will relax overnight with
lows dropping into the 20s across the area.
&&
.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
Northern New England will become positioned between high
pressure offshore and low pressure developing over the Great
Lakes Tuesday through Tuesday night. Warm air advection will
result in mostly cloudy skies while low level dry air will limit
precipitation chances until Tuesday night. Despite the cloud
cover, highs will run above normal ranging from the mid 40s
north to near 50 degrees across the south.
The atmosphere continues saturate Tuesday night with weak
forcing from WAA resulting in rain chances increasing overnight.
Along and north of the mountains temperatures may be able to dip
below freezing before precipitation onset resulting in pockets
of freezing rain. Temperatures will take on a non diurnal trend
with temperatures rising into Wednesday morning reducing the
threat for freezing rain. At this time, coverage, duration and
confidence do not reach Winter Weather Advisory thresholds.
The key message is that localized northern valleys may see
enough icing to slicken roads surface late Tuesday night while
the threat for icy surfaces diminishes Wednesday morning as
temperatures rise above freezing.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Overview...
A broad low pressure system moves through New England Wednesday
and Wednesday night. A cold front passes through early
Thursday, with drier and cooler conditions accompanying high
pressure to end the week and start the weekend. Another low
pressure system is possible early next week.
Details...
With low pressure centered in the Great Lakes on Wednesday, a
warm front lingers north of New England during the daytime.
Lingering low level cool air across the interior and
northwestern Maine brings lingering showers and drizzle, with
highs gradually climbing into the low 40s by late in the day.
Across southern and coastal areas, more breaks of sun allow
temps to warm into the 50s by the afternoon, with some scattered
showers still possible.
Wednesday night a weak triple point low crosses New England,
bringing another round of more organized shower activity. The
cold front then clears the area by Thursday morning, with drier
and cooler air moving in during the daytime on Thanksgiving.
Breezy conditions are expected for Thanksgiving with westerly
gusts of 20- 30 mph. Temps hold in the mid 40s downwind of the
mountains most of the day, with 30s expected across the north.
Breezy conditions continue on Friday as cooler air continues to
move in on northwesterly flow. Highs tops out in the upper 30s
to low 40s downwind of the mountains, with low 30s across the
north. Upslope snow showers will also increase on Friday across
the higher terrain, and continue on Saturday. High pressure then
moves off the East Coast on Sunday, making way for the next
potential system early next week.
&&
.AVIATION /17Z MONDAY THROUGH FRIDAY/...
Short Term...Mainly VFR tonight through Tuesday. Clouds thicken
and lower late Tuesday with light rain and low cigs likely
bringing MVFR to IFR conditions Tuesday night.
Long Term...Ceilings likely improve to MVFR across southern
terminals on Wednesday with scattered showers, with IFR likely
holding longer at AUG and RKD. MVFR to IFR is likely Wednesday
night into Thursday. VFR likely returns to most terminals on
Thursday and prevails into the weekend, except at HIE and LEB
where MVFR ceilings in upslope flow is more likely into
Saturday. VFR is likely Sunday, before the next system brings
restrictions early next week with rain and snow possible.
&&
.MARINE...
Short Term...High pressure builds in from the SW tonight and
shifts south of the Gulf of Maine Tuesday. Winds shift out of
the SW tonight with winds producing SCA conditions along the
outer waters Tuesday into Tuesday night.
Long Term...Fog is possible on Wednesday, then a cold front
crosses the waters Wednesday night. Westerly gales are possible
starting Thursday and lingering into early Saturday. SCA
conditions then subside into Sunday with high pressure build
in.
