Area Forecast Discussion
National Weather Service Gray ME
1033 PM EDT Sun Sep 8 2024

.SYNOPSIS...
Northwest breezes continue on Monday with mainly sunny
conditions. The rest of the week will feature fair weather and
gradually warming temperatures. Temperatures could be quite warm
by the end of the week.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
1030 PM Update...No changes at this time as forecast is on track
with winds, sky cover, and temperatures.

705 PM Update...Little change to the going forecast. Gusty
winds will continue to diminish this evening.

Previously...

A weak shortwave trough swinging around the upper level low
pivots through this evening, bringing some scattered shower
activity to the higher terrain. Winds become a bit more gusty
for a time behind this trough this evening, but then will ease
through the remainder of the overnight. Temps looks seasonably
cool overnight as a cool and dry airmass remains in place. Lows
drop into the 40s in most areas, with some upper 30s possible
across the northern valleys. These areas also stand the chance
to see some patchy fog, but the westerly breeze likely keeps it
more patchy than the last few mornings.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/...
Temperatures start their rebound tomorrow as high pressure
builds across New England. Highs warm into the mid 70s across
the south, with mid 60s across northern areas. The morning looks
to be mostly sunny, but clouds increase a bit during the
afternoon as another weak shortwave trough pivots into the area
during the afternoon hours. Some scattered showers are likely
with this feature, especially across western areas and the
higher terrain. These arrive during the late afternoon, and
gradually decrease in coverage through the evening. Given how
today`s activity was a little more robust than the high res
guidance was originally suggesting, tomorrow`s forecast opted
for more coverage with the showers.

Clouds clear and showers diminish through the evening tomorrow
night, with lows dipping into the 40s again in most spots.
Valley fog looks a little more likely tomorrow night as winds
ease more than tonight. But otherwise a fairly tranquil night is
expected.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Models still showing big ridge across across the center of NOAM
at 500 MB developing mid to late week. I till think well see
mainly sunny skies and above normal temps in the Wed-Fri time
frame, with highs pushing into the low to mid 80s by Thu or Fri.
Questions come in as to whether a wave to our NE can push a
back door front through the area late in the forecast period. I
think the strength of the ridge is somewhat dependent on what
happen to the remains of what is likely to become Tropical
Cyclone Francine in the next day or so. Still it looks mainly
dry through the period, and temps may be the only uncertainty
for next weekend.

Temps on Tuesday still running fairly close to normal with highs
in the mid 60s to mid 70s, although Tue night is setting up to
be a good rad cooling night, so could see low around 40 in the
mtns valleys and generally around 50 in the S. Wed is the
transitions as we arm up a little with highs mainly in the 70s,
and on Thu-Fri we get our mini autumn heat wave, with highs in
most spots in the 80-85 range perhaps a little higher in the S
on Friday. As mentioned the weekend is still up for grabs
regarding temps but highs could continue in the 80s or drop back
closer to the normal of the 60s and 70s.

&&

.AVIATION /03Z MONDAY THROUGH FRIDAY/...
Short Term... VFR conditions prevail during the daytime today
and tomorrow, with valley fog possible at HIE and LEB each
night. Gusty westerly winds up to 25kt ease this evening. A
brief shower is possible at HIE and LEB late tomorrow afternoon.

Long Term...Mainly VFR through the end of the week, with the
vly fog at KLEB/KHIE possible overnights.

&&

.MARINE...
Short Term...Seas remain near 5ft this evening, with gusty
westerly winds freshening behind a passing trough. For this
reason, an SCA has been issued for the outer waters overnight
tonight for the gusty winds. Winds and seas gradually ease
tomorrow as high pressure becomes established across the waters.


Long Term...Winds/seas remain below SCA criteria through next
week.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Small Craft Advisory until 5 AM EDT Monday for ANZ150-152-154.
