URGENT - WINTER WEATHER MESSAGE
National Weather Service Gray ME
411 AM EST Mon Feb 1 2021

...SIGNIFICANT SNOW ACCUMULATION LATER TODAY THROUGH 
TUESDAY NIGHT...

.An area of low pressure will travel north along the East Coast 
today before moving into the Gulf of Maine late Tuesday. Significant 
snow accumulation is likely for the region. In addition, gusty 
northeasterly winds may result in blowing and drifting snow at 
times, mainly along the coast. While the bulk of precipitation will 
fall as snow, some sleet will mix in as heavy snow exits to the 
north, particularly along the Midcoast of Maine. Later Tuesday 
afternoon and evening another round of moderate to locally heavy 
precipitation is possible over the Midcoast extending into central 
Maine.

What forecasters said that day

The local office's own words before this winter storm watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Gray, ME wrote its last area forecast discussion before this winter storm watch went out at Jan 30, 10:16 AM EST, 5 hours 9 minutes earlier.

Area forecast discussion, Jan 30, 10:16 AM EST, 5 hours 9 minutes before
Area Forecast Discussion
National Weather Service Gray ME
1016 AM EST Sat Jan 30 2021

.SYNOPSIS...
High pressure builds east across southern Canada resulting in a
dry and cold weekend. An area of low pressure develops along
the Mid Atlantic Coast early next week and moves to the
northeast. It will pass offshore late Monday Night through
Wednesday of next week with a period of snow and gusty winds.
Warmer high pressure builds in behind the storm late next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1015 AM Update...Just a few minor adjustments to the forecast
for the rest of the day. Increased forecast cloud cover for
western and northern NH for persistent stratocu. Otherwise, just
a few minor adjustments to temperatures and wind.

715 AM...Just a few tweaks to sky/winds and temps. Regarding
temps, a few places did manage to decouple late and managed to
get KEEN to -10 and KLEB to -4. But otherwise any clouds this
morning should give way to sunshine later today, even in the
mtns.

Previously...Low pressure offshore tracks south of the Grand
Banks today, moving away from the area, while sfc high shifts in
from the W. Winds will slacken during the day and should be
less gusty as well. Any morning clouds in the mtns will begin
breaking up in the afternoon. Despite the sunshine it will be
cols with highs ranging from around 10 in the N, to around 20 in
the S. Daytime wind chills will run about 10F below the air
temps.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
The high will cross right over New England tonight, and with
clear and calm conds will allow for widespread decoupling and
rad cooling. Lows tonight will should drop quickly this evening,
although there will be little to no wind. Mins bottom out
between 10 and 20 below in the mtns, while closer to the coast
and in srn NH the will range from -5 to +5, although colder
spots could be closer to -10.

On Sunday, look for mainly sunny skies and light winds. It will
be warmer than Saturday, but still below normal, with highs
around 20 in the mtns, to the upper 20s in the S. Sun night will
be mainly clear through much of the night and should see another
good rad cooling, but lows will not be quite as cold as Sat
night, ranging from the single digits below zero in the N to 5
to 10 above in the south.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Potentially Significant Winter Storm Next Week...

Monday morning, high pressure will be firmly planted over
Quebec, extending through New England toward Bermuda... forming
a dipole with low pressure to its south over the Ohio Valley
extending toward the DELMARVA. Looking aloft, an elongated
trough presently over the Rockies will track east with time...
as this trough approaches the East Coast early Monday, low
pressure over the Ohio Valley will fill in with coastal
cyclogenesis feeding off the Gulf Stream (a la Miller Type B).

Locally, we'll see winds pick up out of the northeast on Monday as
a fairly classic CAD sets up out of Canadian high pressure.
Temperatures will top out in the 20s with cirrus streaming in
from the south... and eventually lower clouds filling in along
southern zones and the coastal plain with mid-level onshore flow.
While some areas of light, ocean- enhanced snow are possible
Monday afternoon into the evening, the main show arrives a
little later.

Deterministic and ensemble suites are in good agreement that a band
of snow associated with the sytem's warm front will arrive from the
south late in the evening to overnight Monday, spreading northward
through the forecast area by Tuesday afternoon. Expect at least a
couple inches of snow with this feature, up to several inches where
mesoscale enhancement can be realized... at this time southern
and coastal zones stand the greatest chance of higher totals
with this wave during the morning hours, which makes sense given
moisture availability and closer proximity to forcing associated
with the low/mid-level circulation strewn out over the waters.
A strong easterly jet means some upslope enhancement as well.

Focus shifts somewhat beyond this point... a shortwave racing across
the Canadian Plains pushes into the backside of the long wave over
the East Coast, which causes the system as a whole to amplify and re-
orient more negatively. At the surface, broad low pressure
oriented SW to NE across the 70W/40N benchmark early Tuesday
deepens and shifts more N to S near the Gulf of Maine. This
transition dictates the position and amounts of additional
snowfall over the area, especially for Maine. In general am
expecting a renewal of FGEN forcing during the second half of
Tuesday on the northwest side of the low/mid-level wave...
current model trends place this generally over Maine. This is
however a more uncertain portion of the forecast with fairly
significant spread in solutions with one extreme (a la 00Z Euro)
taking low pressure north into Downeast Maine and the other
extreme (a la 00Z GFS) tracking it through Nova Scotia. The
former would bring more significant snowfall on the order of
several inches to Maine and the Whites with overall stronger
and better phased dynamic forcing; the latter offering a faster
exodus on Tuesday and lesser snowfall amounts for Maine. Also
of note is the possibility that a low track through Maine
introduces warmer air along the Maine coast which may turn snow
to rain, although ascent will be displaced to the north with
that scenario so wouldn't make a big dent in snow totals.

To wrap things up... medium to high confidence holds in a
fairly long-duration, all- snow event with impacts centered on
Tuesday. Taking a quick look at wind fields, gusts will pick up
Monday night through Tuesday with the current probabilistic
suite and BUFKIT soundings indicating favorable lapse rates for
gusts in excess of 30 mph, strongest at the coast and at
elevation. Speaking of increasing onshore winds... will have to
closely monitor surge trends for coastal impacts including minor
flooding and splash-over, especially with a more westward
track. While most mid- level forcing exits with surface low on
Wednesday, the upper level low continues to spin overhead so
have bumped up cloud cover... and added a chance of showers as
lapse rates will be favorable. Low level ridging eventually
works in for a brief time Thursday as the upper low departs to
the maritimes, but another system crossing through the Great
Lakes region is close on its heels and will impact the region
toward the end of the week. Looking like a warmer system in
general given a track further north. Went with the NBM for
Thursday through the end of the forecast to focus on the early
week storm.

&&

.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
Short Term...Mainly VFR thru Sun night. MVFR cigs linger
through this morning at KHIE, but should be VFR by midday.

Long Term...Ceilings will lower from south to north late Monday
into early Tuesday with increasing NE winds and SN breaking
out, leading to periods of IFR or worse through Tuesday.
Conditions will begin improving as dry air works in on the
backside of the system from the southwest later Tuesday,
although restrictions over much of Maine may persist into
Wednesday. Winds back to the north on Tuesday, then to the
northwest Wednesday with wind gusts in excess of 30 mph
possible.

&&

.MARINE...
Short Term...Extended SCA thru this morning in the bays, and
through tonight in the outer waters, which will mainly be for
seas lingering around 5-6 later today into tonight.

Long Term...An easterly jet associated with an approaching storm
system will increase winds and seas late Monday into Tuesday
with a period of Gales possible. Seas will also build during
this time, to 10-15 ft nearshore by Tuesday. Winds orient more
northerly late Tuesday as low pressure approaches the Gulf of
Maine, to northwesterly Wednesday as low pressure exits to the
northeast with Gales gradually diminishing. SCAs persist with
active seas into early Thursday before high pressure returns.
