What happened

The episode as NWS GYX wrote it up.

On December 16th low pressure develop near Chesapeake Bay and slowly moved northeastward along the coast to a position near Nantucket late in the day. Eventually low pressure moved into the Gulf of Maine on December 17th and continued towards Nova Scotia. Despite a climatologically favorable track for significant snowfall, the antecedent near surface air mass was marginal for snow south of the mountains. Temperatures aloft were cool and supportive of snow, but rain mixed in south of the foothills. Due to the heavy wet snow, significant power outages occurred across interior Maine with 80,000 outages reported. Oxford, Franklin and Somerset Counties were impacted the hardest. There was a significant upslope and elevation component to snowfall totals when precipitation finally came to an end on the 17th.

Area Forecast Discussion
National Weather Service Gray ME
453 AM EST Fri Dec 16 2022

.SYNOPSIS...
Low Pressure currently over New Jersey will track towards the
southern New England coastline today. Precipitation has already
overspread southern New Hampshire and will continue to expand
over the rest of the forecast area this morning. Interior
locations are still expected to see heavy snow while areas
across southeast New Hampshire and coastal Main see a mix of
rain and snow changing to all rain. There have been no changes
to the current Winter Weather Headlines with this winter storm
expected to linger through Saturday. The system will be slow to
exit into the North Atlantic with continued chances for snow
showers in the mountains through Monday while areas south of the
mountains see an end to precipitation Saturday night. Relatively
quiet weather is expected through mid week with another
potential impactful system late next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The first widespread winter storm of the season is upon us and
it is not a simple forecast.

Deep easterly flow has established a coastal front running along
the western ME coast and cutting inland between DAW and
PSM...thru MHT...and then south of AFN. Southeast of that line
is comfortably predominately rain today. Along and just north of
that line is the most difficult forecast.

For starters we are in a period where the dominant mode of
forcing is transitioning. Currently WAA from the primary low
pressure over the Upper Midwest is driving precip. As a result
precip character is a little more convective and showery in
nature...and becoming more so as the WAA weakens. Eventually
this will be taken over by stronger forcing from the secondary
low pressure driven by divergence in the poleward exit region of
the upper level jet. This mode of forcing favors deformation and
an arcing or pivoting band of precip. In that sense QPF was not
particularly difficult to address.

Snowfall on the other hand...this will largely depend on precip
intensity and elevation. That easterly flow will keep temps
pretty marginal for a large chunk of the forecast area southeast
of the mtns. As you near the coast the depth of the above
freezing air near the surface will approach 1000 ft at times.
This is borderline for snow...so as precip intensity picks up
the latent cooling of melting will help keep ptype snow. The
heavier rates will also allow snow to accumulate before melting
on the ground. Since temps will be near freezing around 1000
ft...elevations above that should have no trouble staying mainly
snow today.

With such fine margins...there is big bust potential in either
direction along that coastal frontal zone. Some Bufkit forecast
are quite robust in the PWM area for snowfall...but model snow
depth fields...which often can more accurately depict snowfall
amounts in the marginal/mixed scenarios show very little locally
including into the foothills.

Ultimately I nudged the forecast slightly in the warmer
direction...with only small changes to snowfall as a result. No
changes to the headlines.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
After sunset will be well timed for flow to start becoming more
northerly into the center of low pressure and will likely start
seeing temps tick down as a result. This will help transition
precip more towards snow in most areas. I suspect this is the
time period when much of the area near the coastal front will
see accumulation...which would affect the evening commute. Even
inland this should be when the bulk of the accumulation occurs.

Flow becomes more westerly and downsloping from south to north
Sat...starting around mid morning. This will taper precip in
that direction as well.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Overview: Primary surface low will be near the Bay of Fundy
Saturday evening while aloft a closed low will be over the
eastern Great Lakes. This upper low will slide across the
forecast area Sunday and will become vertically stacked with the
surface low over the Canadian Maritimes Monday morning. The
proximity of the surface low and the upper low traversing the
region will allow for continued chances for snow showers,
primarily in the mountains through Monday. The vertically
stacked low will pull into the north Atlantic Tuesday with short
wave ridging sliding over New England through Wednesday for
mostly dry conditions. Global models and their ensembles
continue to have a strong signal for a large low pressure system
to develop near the Mid Atlantic region around next Thursday
and track up the Eastern Seaboard Friday. This system will have
the potential to bring snow and/or rain depending on the track,
along with strong winds. As this system is 7 days out the track
will likely vary over the next several days. A main area of
concern with this system will be coastal impacts as an inland
track will allow for strong onshore winds and surge as we enter
a period of high astronomical tides.

Forecast Details: Precipitation from our first impactful winter
storm will have ended or be tapering off Saturday evening across the
southern third of the forecast area. Across northern and eastern
zones light snow will continue into Saturday night with most areas
outside of the mountains seeing an end of accumulating snowfall
after midnight. By Sunday morning areas south of the mountains will
see partly to mostly sunny skies with partly to mostly sunny skies
expected Monday. In the mountains and far northern zones there will
be continued chances for snow showers Sunday through Monday as the
upper low becomes vertically stacked over the Canadian Maritimes and
moisture rotates into these areas. Highs on Sunday and Monday will
be in the upper 20s to low 30s across the north and into the upper
30s to near 40 degrees along the coastal plain. Westerly winds will
be breezy both days, with peak winds topping out around 30 mph with
much higher gusts in the mountains.

Short wave ridging looks to bring quiet conditions Tuesday and
Wednesday, although disturbances tracking across Quebec will bring
more in the way of clouds across the north with slight chances for
snow showers in the mountains.

The next potent trough digs southeastward across the Plains Thursday
while surface high pressure looks to keep northern New England dry
until late Thursday. There has been rather good model to model
agreement and run to run continuity for this time range in a large
low pressure system developing near the Mid Atlantic region late
Thursday and Thursday night. The current envelope of ensemble
solutions ranges from low pressure tracking well inland over Upstate
NY to outside of the 40N/70W benchmark and we are likely several
days out from a track consensus. The main take away is that this
system will have potential to bring travel impacts from snow and/or
rain going into the Holiday Weekend. There will also be potential
for impactful winds along with coastal impacts from onshore winds
bringing the threat of surge during a period of high astronomical
tides.

&&

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
Short Term...Largely MVFR or IFR across the area this morning.
Conditions are expected to steadily deteriorate as precip moves
in. Widespread IFR is expected today whether in SN or in low
CIGs where ptype remains RA. The one exception may be
HIE...where periods of MVFR CIGs are possible. IFR conditions
are likely to linger into Sat...as precip will be slow to
dissipate. A very gradual improvement from south to north is
expected thru the day Sat.

Long Term...Ongoing light snow will likely continue restrictions at
KHIE, KAUG, and KRKD Saturday night with remaining terminals seeing
conditions improve to MVFR and then VFR by Sunday morning. KHIE will
see -SHSN Sunday into Monday bringing the threat of continued
restrictions and cannot rule out continued chances for at least MVFR
at KAUG and KRKD. The remaining TAF sites will likely see prevailing
VFR Sunday through Wednesday, with KAUG and KRKD likely seeing
prevailing VFR Monday through Wednesday. By Monday night -SHSN will
end at KHIE for prevailing VFR into Wednesday.

&&

.MARINE...
Short Term...No significant changes. Gale warnings remain in
effect for all waters...with a period of near storm force gusts
possible on the outer waters late today and tonight. Winds and
seas will gradually diminish as the storm pulls away...but not
until later Sat.

Long Term...Winds shift out of the NW and then W Saturday night into
Sunday with elevated seas persisting into Sunday morning. Wind
gusts and seas from Saturday night through Monday night will
likely warrant SCAs with winds and seas dropping below SCA
thresholds Tuesday into Wednesday. There is potential for
another strong low pressure system to track along the East Coast
late in the week.
