Area Forecast Discussion
National Weather Service Gray ME
140 PM EDT Sat Aug 2 2025

.SYNOPSIS...
High pressure will be in control of the weather for most of the
week. A weak frontal boundary will cool temperatures off on
Tuesday and Wednesday before increasing once again towards the
end of the week. Overall conditions will remain mostly dry
except for a few passing showers in the mountains.

&&

.NEAR TERM /THROUGH TONIGHT/...
Broad high pressure stretching from the Great Lakes to New England
will keep dry and mostly sunny conditions the rest of the day with
temperatures mainly in the mid to upper 70s. The seabreeze will
develop and move onshore this afternoon but shouldn`t make it too
far inland. For those areas that see the seabreeze move through, it
will get a bit breezy with temperatures coming down a few degrees.

Also, skies may start to get hazy as elevated smoke from Canadian
wildfires is modeled to begin increasing across the area later
this afternoon with west to northwest flow aloft, and this trend will
continue through Sunday.

Aside from any smoke/haze, a shortwave may bring a brief
increase in clouds this evening into tonight (mainly northern
areas) and maybe a couple of showers in the western ME
mountains. Otherwise mostly clear skies and light winds should
allow temps to cool pretty efficiently, but it won`t be as cool
as last night/this morning. Temperatures will range from the 40s
in valley/normally cooler location to the 50s elsewhere, and
valley fog is possible in some areas, especially along the CT
River.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
High pressure becomes centered to the southeast on Sunday as a
weakening frontal boundary approaches from the north. The front
may end up bringing a shower or two across the mountains, but
the airmass will be too dry to support precip for the rest of
the area. Ahead of the front, increasing low-level west to
southwest flow will usher in warmer air and will bring high
temperatures up a few degrees of those of today with most seeing
lower to mid 80s. However, hazy skies from the elevated
wildfire smoke may end up hindering temperatures by a degree or
two.

Another mostly clear and dry night is expected Monday night
with valley fog again possible. Lows will be mostly in the 50s
with 40s in some valley locations.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
...High Impact Weather...
    * No high impact weather is expected with quiet weather
    * Cumulative drying will continue this week

Mostly quiet weather expected in the extended period with no
strong frontal features. Pattern will consist of a broad 500mb
trough to our north in Canada and very weak zonal flow to our
south. At the surface, high pressure will be in control
throughout the period. Monday will start with a very weak
frontal boundary pushing south across central Maine. Moisture
profiles are very limited, so maybe a stray shower is possible
across Somerset County, but remainder of area will remain dry.
The biggest impact will be another push of drier air Monday
night, but not expected to reach into southern areas as the
boundary washes out across central New Hampshire. Tuesday
through Wednesday the CWA will have a boundary stalled out
across the region, with the potential for a few afternoon
showers, but confidence is so low at this time, consensus
forecast keeps pops very low. Overall expecting near normal
temperatures for this period with mostly clear skies. Winds will
remain light and overall weather looks goods. Temperatures will
be trending upward by Thursday and definitely Friday as heights
rise and the surface ridge begins to move to the east allowing
for return flow. Looking to remain dry right into the end of
next week. This will continue the summer rainfall deficits for
most areas.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Short Term...Valley fog may again bring restrictions to HIE and
LEB tonight into early Sunday and also Sunday night. Elevated
wildfire smoke is modeled to return across the area later today
and stick around through Sunday. It`s possible this may cause
visibility reductions to MVFR at times.

Long Term...No significant aviation weather impacts expected
through this period with limited stratus incursions expected as
high pressure and relatively low dewpoints keep the threat for
low marine stratus low. In addition, no significant rainfall
chances expected.

&&

.MARINE...
Short Term...Winds become east to southeast this afternoon as
the seabreeze develops and then further veer to the southwest
this evening and tonight as high pressure becomes centered to
the southeast of the waters. The pressure gradient tightens
Sunday afternoon into Sunday night as a frontal boundary
approaches from the north (and stays north of the waters), and
gusts may increase to 20-25 kt.

Long Term...Seas will remain below SCA conditions with a
persistent area of high pressure over the coastal waters next
week. No significant moisture pushes are expected until late
next week, so the fog threat remains low. Thunderstorm activity
also looks very limited.
