Area Forecast Discussion
National Weather Service Gray ME
1101 PM EDT Thu Apr 25 2024

.SYNOPSIS...
High pressure will continue to build over the region into
Saturday. As winds turn to the southwest on Saturday a warming
trend can be expected over the weekend in to early next week. A
weak front will bring a few showers Saturday night into Sunday.
Monday will be warm away from the coast, with cooler
temperatures along the coast where an onshore flow of cooler air
will develop. Expect a better chance of showers on Tuesday.

.NEAR TERM /OVERNIGHT/...
1100 PM Update...Sun has set, winds are calm in more places than
not. Temperatures now cooling through the 30s, and into the 20s
in some places.

825 PM Update... Little to update, little to report. The sun is
setting, winds are calming, and temperatures will start falling
off precipitously in the coming hours.

Previously...
Breeze today subsides tonight as a low level inversion sets up.
Given the dry conditions and calm winds, will see temperatures
fall off overnight. Didn`t stray far from the night shift`s
forecast lows tonight, with 20s across much of the area and some
teens in more prominent rad cooling locations.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
Friday, high pressure moves overhead. Don`t expect much change
from today...another sunny, dry day. Winds may be just a bit
lighter, perhaps by 5 mph or so. This decrease in offshore wind
direction and speed could help a afternoon seabreeze move inland
quicker. While highs in the mid to upper 50s are expected
across much of the area, immediate coastal locations may see
these values dipping mid afternoon as this marine air
infiltrates.

Friday night will again be calm, and have blended some overnight
lows towards MOS guidance to account for another night of
radiational cooling.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A rather changeable weather pattern in the long term forecast
with a few opportunities for showers mixed in with dry periods.
Temperatures will warm to at or above normal conditions for much
of the area this weekend and Monday. An onshore wind component
will prevail along the coast for much of next week resulting in
noticeable cooler conditions along the coast.

In the dailies:  On saturday high pressure over the region will
drift offshore by days end.  This will result in light winds to
become southwest which will initiate a start to a warming trend. Low
dewpoints on Saturday will bring one more day of low relative
humidities which will could have implications on fire weather
concerns. A weak warm front will cross the area Saturday Night into
Sunday which may result in a few showers. Expect coverage to be
limited as aloft strong ridging will persist which will likely
result in the shower activity to dry out as it moves east.
Best chances of showers will likely be in northern most areas.
Expect dewpoints and relative humidities to increase during the
day on Sunday. Monday we will be in the warm sector between
offshore high pressure and low pressure over southern Canada.
The warm front become stationary along the Northern New England
Canadian border. This will become the focus of another round of
showers on Tuesday as upper level energy moves along the front.
Initially the best chances of showers will be over northern
areas. As the upper level ridge breaks down, during Tuesday
Afternoon a cold front will move east. There may be a weak area
of low pressure that develops on the front as it moves east.
This will serve as a focus area for more widespread showers
across all areas Tuesday Afternoon and Evening. Weak high
pressure builds in for Wednesday before another round of showers
on Thursday. A period of steadier rain is possible Thursday
should low pressure form on the front. Right now the most
aggressive global model that indicates low pressure forming on
the front is the operational ECMWF...while it`s AI counterpart
does not. The GFS forms the area of low pressure further north
an keeps most of the rain north and east of the area.

&&

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
Short Term...VFR. Light and variable winds tonight, picking up
again after 14z Friday. A seabreeze may affect coastal terminals
after 18z Friday, switching winds south. This washes out
overnight, with winds again becoming calm.

Long Term...
Expect VFR conditions Saturday with MVFR conditions Saturday
Night and Sunday. Northern areas may have localized IFR
conditions in scattered showers. VFR to MVFR conditions Monday
with areas of IFR conditions Tuesday in developing showers. &&

&&

.MARINE...
Short Term...Conditions below SCA expected as high pressure
drifts overhead. A more onshore component is continued as this
high shifts east Saturday.

Long Term...
Wind and waves to remain below SCA conditions through the
extended forecast period.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...None.
