Area Forecast Discussion
National Weather Service Gray ME
218 PM EDT Thu Jul 30 2026

.WHAT HAS CHANGED...
No significant changes since the previous forecast cycle.

&&

.KEY MESSAGES...
1. Scattered showers remain possible through this evening with a
drying trend Friday into Friday night.

2. We will remain mainly dry through at least Saturday, but
unsettled weather should return late Sunday into Monday.

&&

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...

The combination of some weak daytime instability and the upper
level low/cold pool aloft will continue to result in some
scattered showers through this evening, before becoming more
isolated overnight. Low temperatures will be into the lower to
middle 50s. Patchy fog is likely overnight, especially across
the valleys and in locations that received recent rainfall.

Low pressure will exit well to our northeast on Friday as
surface high pressure builds to our south. This will allow for a
brighter and warmer day with high temperatures into the lower
80s under partly cloudy skies. A few diurnally driven showers
cannot be ruled out though as we remain under weak cyclonic
flow. Friday night will feature dry conditions with low
temperatures into the 50s.

KEY MESSAGE 2 DESCRIPTION...

An upper level ridge axis will cross the region on Saturday which
will keep the area mostly dry, but a few isolated mountain
showers/storms will be possible. Temperatures will increase on
Saturday with the ridge moving overhead, with highs expected to
range from the mid/upper 70s north, to the low/mid 80s elsewhere.

On Sunday, we transition back into southwest flow aloft as the next
trough approaches slowly from the west. This will keep temperatures
similar to Saturday but with abundant cloud cover in place, it could
be just a touch cooler. The next chance for widespread rainfall will
then move in late Sunday, potentially sticking around through Monday
evening/night. As of now, this system doesn`t look to be a prolific
rainmaker with NBM probabilities of a half inch or greater only
maxing out in the 20 to 50 percent range, but most will see at least
some rain with the best chances in the foothill and mountains. After
this system exits, the rest of the week looks fairly quiet with
normal to above normal temperatures.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Through 18Z Friday: MVFR to IFR restrictions will be common
tonight due to low ceilings and overnight FG. Winds will be
light out of the north. Mainly VFR conditions are then expected
for much of Friday, although a few scattered afternoon showers
may result in brief restrictions. Winds will be out of the NNW
at 5-15 kts. No LLWS is anticipated through the period.

Friday Night: VFR conditions expected outside of possible valley
FG. Light and variable winds expected.

Outlook...

Saturday: Largely VFR conditions expected. Local/brief MVFR or lower
possible under any isolated mountain showers/thunderstorms.

Sunday-Monday: Increasing chances for showers and storms may lead to
areas of MVFR/IFR restrictions late in the day Sunday through Monday.

&&

.MARINE...
Winds and seas will continue to diminish through this evening
with conditions below SCA criteria expected tonight through
Friday night.

Winds and seas are generally expected to remain below SCA thresholds
thru the remainder of the forecast period. However another round of
fresh onshore winds are possible Sun, and gusts may approach 25 kt
outside of the bays.
