Area Forecast Discussion
National Weather Service Gray ME
958 AM EDT Fri Oct 18 2024

.SYNOPSIS...
High pressure brings an extended moderating trend with dry
conditions through at least early next week. By the weekend
temperatures will be pushing the 70s, with little if any
precipitation in the forecast. The next change of precipitation
looks to be around Wednesday when a cold front approaches from
the west.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
805 AM...Quick update to allow for expiring frost advisory this
morning, with another sunny day, but milder than Thursday.

6:59am Update... No notable changes with this update, just
tweaked temps to trends so far this morning. Otherwise, the
forecast remains on track.

Previous...

Another dry and nearly cloud-free day is expected as ridging
remains firmly in place across the Northeast. Low pressure off
the Mid Atlantic coast begins to move away later today. A bit
of a northerly breeze will be noticeable along the coast in
association with this system, but will ease by later this
afternoon. The moderating trend continues today as warm air is
advected to the west of the ridge and then southward into New
England. This results in highs that are a few degrees warmer
today, with most areas expected to reach the upper 50s to mid
60s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Tonight looks quite similar to this past night, but will likely
be a few degrees warmer as the airmass continues to moderate.
Clear skies, light winds, and low dew points set up for another
night of radiational cooling with temps ranging from upper 20s
across the north to the mid 30s across southern areas and along
the coast.

High pressure remains in control again tomorrow, with another
nearly cloud-less day and warming temperatures. Tomorrow looks
to be about 5-7 degrees warmer that today, with highs ranging
from the low to mid 60s across the north, to the low 70s across
parts of southern New Hampshire and southwest Maine.

High astronomical tides are likely to push water levels to near
flood stage again during the midday high tide tomorrow.
However, with a lack of wave action, impacts are expected to
remain minimal.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
The northern reaches of deep layer ridging will persist across
New England through at least early next week while any airmass-
changing short wave troughs remain to our north. The result will
be dry and warm weather during the day and cool temperatures at
night. High temperatures will be at least 10 degrees above
normal across the board, with some locations reaching 15+
degrees above normal by Monday.

Deterministic and ensemble data are in reasonable agreement that
our next chance for showers will be around Wednesday as a cold
front passes through the region. Unless a significant change
in the pattern occurs, meaningful rainfall may be hard to come
through the end of the month.

&&

.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
Short Term...Mainly VFR conditions are expected to prevail
through tomorrow. Brief periods of shallow ground fog can`t be
ruled out at LEB late tonight, but looks unlikely.

Long Term...Mainly VFR Friday through Tuesday. There is some
possibility of valley fog at KHIE/KLEB Saturday night.

&&

.MARINE...
Short Term...NE winds already starting to diminish as that
offshore storm starts to slowly move away, but swell will build
today around 5 ft into tonight before subsiding on Saturday.

Long Term...Winds expected to remain below SCA levels into
early next week as high pressure builds in Sat and holds over
the area. Could see some lingering swell of 5 ft on Sat from
storm well to our SE.

&&

.TIDES/COASTAL FLOODING...
High astronomical tides bring water levels to near flood stage
during the midday high tide across southern areas today. Only
minimal impacts are expected, with some water on low lying roads
and parking lots that typically flood first.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Small Craft Advisory until 8 PM EDT this evening for ANZ154.
