Area Forecast Discussion
National Weather Service Gray ME
925 AM EDT Sun Jun 9 2024

.SYNOPSIS...
Low pressure is expected to bring rain to the region today,
especially in the morning and early afternoon. A few afternoon
showers are expected on Monday and Tuesday. A cold front looks
to move through either late Thursday or Friday with another
chance of showers and thunderstorms.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
920AM Update...Rain continues to increase in coverage across
the forecast area at this time as forecast. Have updated PoPs
slightly based on latest trends in radar and HRRR information.
Temperatures have been adjusted downward some, especially in the
south.

Previously...


Update...
Steady rain will continue to track east this morning per latest
radar imagery from KGYX and surrounding network radars. This
stratiform precipitation will continue until the midday hours
per latest HRRR solution. The precipitation will then become
more showery this afternoon with scattered thunderstorms as
well.

With the low cloudiness and precipitation today, temperatures
will not climb much past the 60s in most areas.

Prev Disc...
A trough will approach the region this morning. Warm air
advection with increased moisture in the presence of a vigorous
upper level trough will allow for widespread shower activity
this morning. By afternoon, pops will be on the downward track
however a few thunderstorms may be mixed in as the atmosphere
destabilizes.

With plenty of cloud cover and the precipitation, temperatures
will be on the cool side today. Most areas will remain in the
60s during the day.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
The chance for any precipitation will continue to lower tonight.
Plenty of low level moisture for today`s showers may allow some
patchy fog to form, however a drier westerly flow will develop
as well. Overnight lows will be in the upper 40s across the
north to the lower to mid 50s in the south.

Yet another upper level low pressure system will approach the
region on Monday. This will allow for more scattered showers,
mainly during the afternoon hours. It will be slightly warmer
with a few breaks in the cloud cover. Afternoon highs will top
out in the 70s for most areas outside the northern mountains.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Overview: Unsettled conditions can be expected to last into
Tuesday, however most of the scattered showers will be confined
to the north. Broad high pressure advances east mid-week, with
drier conditions forecast. Another low pressure system may bring
additional damp weather for late week.

Details: High pressure slides east into Tuesday with mostly dry
conditions forecast. There will be another chance of some
diurnal showers in the afternoon, but moisture is limited. Some
of these may be focused across the mountains where there is
another forcing agent in terrain.

Wednesday looks similar to Tuesday in the way of afternoon
showers. This time comes with more southerly flow to aid in
moisture transport. The higher rain chances this week come
Thursday into the first half of the weekend. Low pressure skirts
north of the Great Lakes potentially bringing a warm sector and
cold front through the CWA. This combination of moisture and
lift will bring chance of some thunderstorms, but it is too
early for specifics on intensity/coverage.

&&

.AVIATION /13Z SUNDAY THROUGH THURSDAY/...
Short Term... MVFR to IFR conditions are expected to enter the
region this morning as showers move across the region.
Improvement is foreseen for later today and tonight. A few
scattered showers may occur again on Monday, but this would be
mainly in the afternoon and across the northern mountains.

Long Term...Ceiling restrictions are possible across far western
ME and northern NH Monday and overnight. There may be some fog
over the coastal waters that nears coastal terminal like PWM or
RKD Tues/Wed.

&&

.MARINE...
Short Term...A southwesterly flow today through Monday will
remain mostly just below SCA thresholds. Seas may climb to four
feet along the outer waters.

Long Term...Below SCA criteria. Upper low pressure finally pulls
north early this week, with high pressure approaching after.
Surface low pressure passes to the south of the waters midweek.
Additional frontal systems may move across the waters towards
late week.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...None.
