Area Forecast Discussion
National Weather Service Gray ME
310 PM EDT Tue Jul 23 2019

.SYNOPSIS...
Low pressure will shift into the maritimes by this evening.
Another area of low pressure will track east along the boundary
south of New England tonight. High pressure will build in from
the west on Wednesday and Wednesday night. A weak frontal
boundary will wash out as it sags into northern zones on
Thursday. High pressure will build south of New England Thursday
night through Saturday and will hold off the coast on Sunday.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
Precipitation will continue to exit into the Canadian Maritimes
this evening. This will allow for a gradual clearing over
southern areas. Across the north, a weak weather disturbance may
bring a brief shower to the mountains this evening as they head
east out of Canada and weaken with time.

It will be a much cooler night then we have seen recently with
lows primarily in the 50s. These temperatures will approach
their dew points in the north and west, allowing for patchy fog
to develop.

Across the south, some cloudiness will linger as yet another
area of low pressure passes by east of our region. There will be
a slight chance for a shower but this will be confined to the
coastal waters.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
Clouds will exit the coastline on Wednesday as the surface low
tracks north and east well off the New England and Mid Atlantic
coastline. Partly to mostly sunny conditions will allow for
temperatures to climb through the 70s during the day.

Patchy fog may redevelop Wednesday night in some areas. This fog
potential will be very dependent on whether clouds advect into
the region from the west late at night in association with an
approaching short wave trough.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...

Weak cold front drifts through northwest zones Thursday morning
but with weak forcing shower and thunderstorm activity looks to
be isolated and mainly over western areas. The rest of the
region looks to remain partly sunny with high temperatures from
mid to upper 70s.

High pressure then moves into the region Friday from the
southwest bringing with it warm southwesterly flow through the
weekend. Temperatures will cool down Thursday night under mostly
clear skies into the 50s before quickly rebounding Friday into
the low to mid 80s.

A slightly warmer and more humid airmass will move into the
region Friday night through Saturday with an area of high
pressure moving off the coast. Low temperatures Friday night
will remain in the 60s and highs on Saturday will be in the mid
to upper 80s under mostly sunny skies.

Saturday night looks to remain quiet under partly cloudy skies
with low temperatures mainly in the 60s. A weak pulse of energy
on Sunday combined with radiational heating may spark a few
showers Sunday afternoon across mainly northwestern zones.
Monday and Tuesday will return to mostly sunny skies with
temperatures in the 80s.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
Short Term...Ceilings will continue to improve this evening as
low pressure exits off the coast. Localized IFR and LIFR
conditions over northern areas and the Connecticut River Valley
in overnight fog. Fog lifts early Wednesday morning only to
redevelop late Wednesday night.

Long Term...VFR conditions will continue through the weekend as
high pressure dominates the pattern.

&&

.MARINE...
Short Term...Winds and seas will remain below SCA levels through
the short term portion of the forecast (through Wednesday
night).

Long Term... High pressure will build in for the end of the
week and into the weekend keeping winds and seas calm.

&&

.EQUIPMENT...The Sugarloaf NWR transmitter is off the air until further
notice. This will be an extended outage as the tower, which was
severely damaged in a winter storm, is rebuilt.

&&

NH...None.
