Area Forecast Discussion
National Weather Service Gray ME
235 AM EDT Sat Jun 8 2024

.SYNOPSIS...
An upper low moving overhead will bring chances of showers and
few thunderstorms today, especially during the afternoon hours.
Somewhat unsettled weather remains possible into midweek as
upper level lows remain persistent over the region.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Persistent showers and thunderstorms training over portions of
Franklin County and perhaps into northernmost Oxford County has
prompted a Flood Advisory for the region for the overnight
hours. Radar estimates were in the 2-3 inch range over a small
portion of the region northwest of Weld and Roxbury.

A large scale upper level trough will remain over the region
today. A slightly drier westerly flow will allow for more
sunshine today than yesterday. However, this daytime warming
will allow for diurnally driven scattered showers today,
especially this afternoon. Models suggest a few thunderstorms as
well this afternoon, primarily over northern areas.

The westerly flow will allow for temperatures to be mild in
southern areas including the coast. Afternoon high will reach
the 70s with the exception of the mountains and the Midcoast
region of Maine which will be limited to the 60s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
A couple showers may linger tonight, however a brief period of
ridging aloft may limit any precipitation. Overnight lows will
drop into the 50s in all areas with chilly readings in the
northern mountains.

Yet another trough will cross the region on Sunday. This will
lead to another increased chance for showers especially over the
northern mountains. After instability will occur once again
therefore a thunderstorm or two cannot be ruled out. It will be
slightly cooler with high temperatures mainly in the 60s to
lower 70s. Warmest temperatures will be over southernmost New
Hampshire.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Previously...
The overall pattern across the northeast in the extended will
continue to consist of moist cyclonic flow due to upper level
low pressure lingering across the northeast US and southeast
Canada. This will lead to unsettled weather at times. But at
this time it does not look like there will be any washouts, just
mainly chancy to low likely PoPs for showers and thunderstorms,
peaking in the afternoons with diurnal heating. This will be
mainly true Sunday through Monday before a period of ridging
possibly moves in. Highest PoPs each day are in the mountains,
with lesser PoPs in southern NH where it could be dry most of
the time. Midweek looks drier but there will still be the threat
for diurnal showers.

Temperatures each day will be in the 70s for most folks, with
60s in the mountains.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Short Term...IFR conditions will gradually improve today to VFR
as a drier westerly flow enters the region. There will be
scattered showers however and possibly a thunderstorm mainly
across the north today and Sunday. This will lead to brief
periods of IFR conditions.

Long Term...Local IFR to MVFR conditions possible Sunday morning
at coastal terminals. Otherwise, local MVFR conditions in
showers and isolated thunderstorms Sunday afternoon and again
Monday afternoon. Some nighttime fog possible, especially where
it rained the previous daytime.

&&

.MARINE...
Short Term...Conditions hazardous to small craft are not
expected through Sunday. Some dense fog is likely again
this morning, mainly off the Midcoast. Seas will be 3-4ft with
some breezy westerly wind gusts approaching 20 kts today.

Long Term...Conditions hazardous to small craft are not
expected through Tuesday. However, there could be areas of low
visibilities in fog.
