Area Forecast Discussion
National Weather Service Gray ME
232 PM EDT TUE JUN 7 2016

.SYNOPSIS...
A cold front will move across the region today producing showers
and thunderstorms, with a few possibly being severe. An upper
level low will move overhead on Wednesday and allow for another
chance of showers and thunderstorms. Cooler and drier weather will
move into the region Thursday and Friday. A low pressure system
brings a chance of rain over the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
High impact weather potential: Scattered severe thunderstorms
with damaging winds and large hail through evening.

2pm.. Convection beginning to initiate across the area ahead of
the upper level trough. Mesoscale models and current conditions
support more convective initiation in the next few hours with a
few cells becoming more organized. Temperatures have climbed to
the 70s with a few 80 degree readings in southern New Hampshire.
Dewpoints are in the low 60s to mid 50s. 18Z sounding shows very
strong shear /around 50kts/ from 0-6km. While there is plenty of
shear instability is rather limited...with current analysis around
1200 J/kg. Expect the convective coverage to increase over the
next several hours as the main trough axis aloft pushes in from
western New York. Most likely area for severe storms is from EEN
to MHT to DAW to LEW. In this corridor moisture remains plentiful
with an axis of 60+ degree dewpoints.

Storms will continue through sunset at which point the lack of
heating will limit shear and allow storms to die off. Skies will
clear with temperatures falling to the 50s overnight.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
Wednesday a trough of cold air aloft will move into the region. At
the surface northwesterly flow will set up as the cold air pushes
into the area. Tightening surface pressure gradient will result in
a few gusts to 20mph. In the afternoon showers may form,
especially in the north where upslope flow will assist. Isolated
thunder and small hail is possible as steep lapse rates remain in
place.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Cyclonic flow will continue Wednesday night into Friday as slow
moving upper low gradually shifts east. Bottom line for the period
will be mostly cloudy skies with occasional showers...mainly in
the mountains and foothills. Temperatures will average well below
normal with lows overnight ranging through the 40s. Highs on
Thursday will only reach the mid 50s to mid 60s. Temperatures
will moderate slightly on Friday as a narrow ridge of high
pressure slowly builds in from the west and clouds begin to
diminish in the afternoon. Expect upper 50s to mid 60s north and
mid 60s to near 70 south.

High pressure will shift offshore on Saturday as another strong
shortwave takes aim at the northeast. Expect variable cloudiness
during the day with highs in the mid 60s to lower 70s.

Strong shortwave digging southeast from Canada Saturday night will
close off over New England on Sunday setting up another stretch
of cool rainy weather Sunday and Monday. Sunday looking like a
washout with low clouds...showers and areas of drizzle along with
a refreshing wind off the water as low pressure crosses the
area. Showers will linger into Sunday night as low pressure
continues east into the maritimes.

Monday looking drier with just a few showers around in eastern
zones during the morning. Increasing downslope flow will produce
a few sunny breaks Monday afternoon. After Monday high pressure
building in from the west will bring a return of quieter weather
through midweek.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Short Term /through Wednesday/... A few thunderstorms this
afternoon and early evening cloud produce strong winds and hail.
On Wednesday conditions will return to VFR throughout the area.
HIE may see MVFR ceilings in the afternoon due to upslope flow.

Long Term...
VFR Wednesday night through Saturday with areas of MVFR ceilings
in the mountains.

&&

.MARINE...
Short Term /through Wednesday/...Winds and seas are expected to
remain below small craft through the day on Wed.

Long Term...Sca's may be needed Thursday.

&&

.FIRE WEATHER...
Recent widespread wetting rains, and a continuation of moderate
to high humidity levels and unsettled weather should keep fire
danger low the next few days.

&&

.TIDES/COASTAL FLOODING...
Can't entirely rule out minor splash-over once again within an
hour either side of the 2 AM Wednesday high tide from Casco Bay
southward to the Massachusetts border. With tide running as
forecast have not issued anything at this time but the tides will
need to be monitored.

&&

.EQUIPMENT...
NOAA Weather radio station WNG575 broadcasting at 162.525 from Pack
Monadnock mountain in New Hampshire will be off the air through
late Thursday for scheduled maintenance. Listeners should use one
of the following alternate stations:
