Area Forecast Discussion
National Weather Service Gray ME
226 AM EDT Tue Mar 21 2017
A cold front will approach from the northwest early on today
and will drop south through the region during the day. A
secondary arctic front will push south through the region
Tonight. High pressure will gradually build in from the west
Wednesday through Thursday with colder than normal temperatures.
High pressure will shift offshore Thursday night. A cold front
will approach from the northwest on Friday and will push south
through the region Friday night. High pressure will build in
from the north Saturday but a warm front looks to approach
.NEAR TERM /THROUGH TODAY/...
A shield of mid level clouds will continue to push overhead
early this morning in advance of a short wave trough and sfc
front. The front will be pretty moisture-starved, but a little
light precipitation will be possible across the interior today.
Overall, temperatures will be warmer than normal, with some
areas in the south expected to reach the 50 degree mark once
.SHORT TERM /TONIGHT THROUGH 6 PM WEDNESDAY/...
A stronger cold front will cross the region tonight. This front
will be the leading edge of an arctic air mass which may be
accompanied by a band of snow squalls. At the very least, we
expect snow showers in the mountains. Temperatures will be
fairly mild this evening, but then drop quickly overnight as the
arctic air rushes in from the west. Wind gusts will likely pick
up behind the front as well, with gusts up to 30 mph not out of
the question late.
Cold northwest flow will be the theme on Wednesday with
temperatures well below normal with winds gusting around 35 mph
in the CAA regime. Low probability for low-end wind advisory
for portions of the CWA. Upslope snow showers in the mountains
will be prevalent.
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
The models are in decent agreement on the longwave pattern through
early next week. We begin the period with the upper trough axis
over northern New England along with the coldest air of the
work week. Fortunately...the trough will lift out during the day
on Thursday with rising heights and moderating 850 millibar
temperatures as ridging takes hold across the region. The center
of the surface high will build by to our south late Thursday
before slipping offshore. By Friday...a broad upper ridge will be
centered across the southeast CONUS with warm frontal clouds
spreading northward into the region along with an increasing
chance for precipitation. A compromise of the various medium range
solutions continues to suggest the frontal boundary will get hung
up across the region for much of the weekend...resulting in a
prolonged period of unsettled weather. There is some hope that
high pressure building by to our north over Quebec province will
nose into the area for Sunday...with clearing skies over much of
the area with the exception of far southern New Hampshire and
southwest Maine. In the dailies...High pressure will build east
and crest across the region on Thursday before retreating offshore
to our south by early Friday. A warm front will move north into
the region late Friday and Saturday then likely stall...resulting
in unsettled weather for much of the upcoming weekend.
.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
Short Term...A period of MVFR cigs will be likely this afternoon
as a cold front moves across the region. VFR conditions will be
prevalent at most terminals this morning. VFR conditions will
return tonight, but a period of snow showers is expected in the
mountains, with the potential for a few snow squalls. VFR
conditions are expected outside of the White Mountains on
Wednesday, but windy conditions, with peak gusts around 35 kt
are likely during the day.
Fri PM -Sat..Areas of MVFR psb in -shra/-shsn.
Short Term...Seas will gradually subside today as long period
swells diminish. A strong cold front is expected to cross the
waters tonight which should allow for northwesterly gales
Wednesday and Wednesday night. Gale warnings are in effect for
all waters except for Casco Bay where a Gale watch remains in
Thu AM...Small Crafts are likely, with winds approaching Gale outside
Fri...Small Crafts are likely, with winds approaching Gale outside
MARINE...Gale Watch from Wednesday morning through Wednesday evening
Gale Warning from 8 AM Wednesday to 8 AM EDT Thursday for
