...GALE WARNING IN EFFECT FROM 7 PM THIS EVENING TO 7 PM EST
TUESDAY...
...FREEZING SPRAY ADVISORY REMAINS IN EFFECT FROM 2 AM TO 1 PM
EST TUESDAY...

* WHAT...For the Gale Warning, northwest winds 20 to 30 kt with 
  gusts up to 45 kt and seas 2 to 5 ft expected. For the

Area Forecast Discussion
National Weather Service Gray ME
1202 PM EST Sun Feb 28 2021

.SYNOPSIS...
A weak system will cross the region tonight with snow and rain
showers. We will see very mild temperatures on Monday before an
Arctic cold front passes through the area in the late afternoon
or early evening. Temperatures on Tuesday will top out in the
teens and 20s along with gusty winds. Canadian high pressure
will nose into New England for the latter half of the week.

&&

.NEAR TERM /UNTIL 7 PM THIS EVENING/...
12:00PM Update... With the sun still making it through the thin
cloud cover, mainly brought up high temps by a few degrees with
this update. The cloud cover looks to remain in place through
the day, and continue to be thickest across southern areas.
Otherwise the forecast remains on track for today.

Previous...
Update...
A quick update as patchy fog continues in the Connecticut River
Valley, however this moisture has been mixing out over the last
couple hours. In the meantime, clouds continue to hold in
across the mountains with a few snow showers across the higher
terrain.

The Special Weather Statement due to icy roads and sidewalks
will be expiring at 8 AM. Road temperatures remain below
freezing despite air temperatures in the 30s in many areas. Have
adjusted the near term temperature forecast as a large
difference in readings continues across the region.

Prev Disc...
A few upslope snow showers will come to an end this morning in
the morning mountains. Otherwise, we shift our focus to the west
where a weak system will approach New England today. Clouds
will be on the increase with the latest HREF indicating mid and
high level moisture will spill over the upper level ridge and
into our area today. Warm air advection late in the day may lead
to pockets of precipitation over southernmost New Hampshire.
Some evaporational cooling may lead to wet bulbing, therefore
some of this light precipitation may fall in the form of snow.

Winds will be relatively light today with temperatures reaching
the upper 30s to mid 40s from north to south for afternoon highs.

&&

.SHORT TERM /7 PM THIS EVENING THROUGH 6 PM MONDAY/...
A broad and weak area of low pressure will reach the southern
New England coastline tonight. Ahead of this system, warm air
advection aloft will lead to light precipitation. Temperatures
will initially fall during the evening hours, before climbing
during the late night period in a non-diurnal fashion. Light
snow will accumulate in northern areas with rain or mixed light
rain and snow continuing over southern areas.

The NBM viewer, HREF and the probabilistic forecast graphics are
indicating the possibility of pockets of light freezing rain
across the higher terrain. However, as we head into March, this
possibility becomes less likely with time with probabilities
relatively low in most areas.

The weak system heads east on Monday with light precipitation
eventually coming to an end. Winds will become gusty
during the afternoon in the wake of this departing system as
Arctic air remains poised to our north. With the upper level low
still to our west, winds will not be aligned during the
afternoon through a deep layer. There will most likely be a few
strong gusts with the passage of the front itself, however the
highest winds will remain in the long term portion of the
forecast.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Overview...Almost all of the consequential weather in the long term
occurs in the first 24 hours as an Arctic front pushes through the
region. A few snow squalls will be possible along the front as it
moves through the region early Monday night, primarily in NH. Behind
the front, a much colder air mass will linger over northern New
England through Tuesday with temperatures returning to near to
slightly above normal levels for the rest of the week. No
significant precipitation is expected beyond Tuesday.

Impacts...Could see flash freeze conditions behind the Arctic front
early Monday night...potentially causing impacts to travel with
slick roads. Wind chills will be down in the negative 20s in far
northern zones Tuesday morning as brisk and gusty northwesterly
winds usher in a much colder air mass into the region behind
the Arctic front.

Forecast Details...Essentially all of the sensible weather in the
long term is expected in the first 24 hours as an Arctic front
continues its push through the region Monday evening and brings a
variety of potential impacts with it and behind it. The initial
primary concern is the possibility for heavier snow squalls amongst
the ongoing snow showers ahead of and along the front...and by
Monday evening, the best chance for any squalls would be any
portions of southern NH that remain ahead of the front. The next
potential impact would be flash freeze conditions in the wake of the
front from Monday evening into Monday night as temperatures rapidly
drop off in strong cold air advection. Precipitation during the day
Monday looks spotty, including that from any squalls, but any
untreated surfaces that remain wet or snowy could become slick
overnight Monday. Upslope snow showers also look likely in the
mountains Sunday night for a few hours after the frontal passage.
Overall, lows Monday night will range from the negative single
digits north to the lower teens south.

The next concern is the gusty northwesterly winds expected behind
the front. Gusts to 30-35 mph are expected beginning early Tuesday
morning, bringing wind chills down into the 20 to 30 below range in
the mountains and the negative teens and single digits elsewhere for
the Tuesday morning commute; a wind chill advisory will likely be
needed for the mountains, but it will feel rather cold throughout
the region. With the Arctic air in place, highs on Tuesday will
range from the positive single digits north to the mid to upper 20s
south, easily the coldest day of the period. The gusty winds
diminish Tuesday evening into Tuesday night.

The rest of the long term period looks rather quiet at this time.
Temperatures bounce back on Wednesday and Thursday to above normal
levels, but another intrusion of cooler air arrives for Friday and
persists through the weekend. Any precipitation looks unlikely from
Tuesday through Saturday...though some mountain snow showers are
possible.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Short Term...Ceilings lower to IFR conditions tonight as a weak
system approaches the region. Some light snow and rain will
continue overnight into Monday with most of the rain in the
south with conditions improving to VFR late in the day Monday.
Winds will become gusty from the west to northwest towards
evening.

Long Term...Widespread VFR conditions expected through Thursday.
Lingering snow showers possible for the NH terminals early
Monday night, but thereafter, no precipitation is expected
except for possibly some snow showers at HIE. Gusty northwest
winds are expected late Monday night through Tuesday evening.

&&

.MARINE...
Short Term...Winds will be relatively light with seas subsiding
today. A southerly gradient will develop tonight with a few
gusts to 25 knots out of the south and seas building to 3 to 5
feet. An Arctic front will cross the waters Monday, switching
winds to the west. Winds will become gusty by late in the day
with building seas.

Long Term...Issued a Gale Watch for all marine zones for Monday
night through Tuesday evening as gusty northwesterly winds
arrive behind an Arctic front. Widespread light to moderate
freezing spray is expected for the waters over essentially the
same period...so a freezing spray advisory will be needed as
well. Winds and seas generally remain below SCA criteria through
Saturday, though marginal SCA conditions are possible on Friday.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Gale Watch from Monday evening through Tuesday evening for
     ANZ153.
     Gale Watch from Monday evening through late Tuesday night for
     ANZ150>152-154.
