The episode as NWS CAR wrote it up.
Low pressure tracking northwest of Maine drew a strong occluded front across the region during the 30th. A strong low level jet crossed the region in advance of the front through the afternoon and evening. The strongest winds occurred along the Downeast coast where southerly winds were generally sustained at 25 to 35 mph with gusts of 50 to 60 mph. However...localized wind gusts up to around 70 mph also occurred. A 69 mph wind gust was reported near Eastport with a 71 mph gust near Trescott...both located in coastal Washington county. Wind gusts of 50 to 60 mph also occurred across portions of the interior Downeast region. Numerous trees were snapped or toppled. Falling trees and branches brought down power lines leading to power outages for thousands of customers. The greatest impacts occurred across coastal Downeast areas were some roads were also blocked due to fallen trees.

Area Forecast Discussion
National Weather Service Caribou ME
119 PM EST Wed Nov 30 2022
.SYNOPSIS...
A strong cold front will approach this evening and cross the
area tonight. High pressure will build south of the area
Thursday into Friday. Low pressure will approach on Saturday and
track north of the region Saturday night. High pressure will
build south of the area Sunday.
&&
.NEAR TERM /THROUGH THURSDAY/...
1pm update... Surface winds are remaining subdued under a
frontal inversion ahead of a warm front. The warm front will
push through this afternoon. Both deeper mixing and stronger
winds aloft should generate the advertised strong winds later
this afternoon through the evening. Still expect the LLJ to
strengthen considerably later this afternoon and evening ahead
of the cold front.
The other concern at this point is the prospect of patchy
freezing rain in northern zones where temps remain below the
freezing mark. Expect any freezing rain to be very fleeting as
the warm advection push is very strong.
Previous Discussion...
Powerful Front will cross Tonight with Winds and Rain...
This morning the warming trend is underway with winds turning
S-SE across the CWA. This is in response to the approaching
storm system from the west. Expecting strong warm air advection
to develop over the coming hours resulting in rapid temperature
rises from single digits and teens to 20s and 30s by daybreak.
At the same time in response to rapid low-level moisture
advection a thick layer of low stratus has pushed across western
portions of the CWA resulting in some scattered flurries and
snow showers. As the low levels moisten up cannot rule out some
drizzle to develop this morning and with surface temperatures
across the terrain of the Longfellows & Central Highlands below
freezing cannot rule out freezing drizzle. Not expecting much
if any in the way of accretion but cannot rule out some slick
spots. If this does develop will handle with SPS headline
instead of a winter advisory given the highly scattered nature
of the possible drizzle this AM. High clouds elsewhere will
become low stratus over the next several hours reaching the New
Brunswick border by daybreak.
During the day today expect a powerful low pressure to track
into James Bay in Canada and dragging a powerful cold front
closer to us during the day. This front is responsible for the
Severe Weather Outbreak down in the Southern US states.
Thankfully no severe weather here but that being said we are
expecting a powerful LLJ to develop which may cause significant
wind gusts across the area as the 500mb trough tilts negative
dragging a strong jet stream overhead.
Precipitation: Intially showers will develop with the increase
of moisture and will eventually see the evolution of a steady
rain shield move into the area. PWATs will be increasing ahead
of the front today and by this evening after precipitation
starts we expect the PWATs to approach 90-95th percentile for
late November. This is a significant amount of available
moisture, combined with strong upper level divergence sets us up
for the potential of localized heavy rainfall. These southerly
events in late November typically present embedded convective
elements, although not expecting thunder we may see areas of
enhanced rainfall. The cold front is expected to push through
based on the trends in Hi-Res guidance between Midnight and 4am.
This will likely bring a rapid end to precipitation except
perhaps some showers scattered about the area. Total rainfall
across the area will range from 1-1.5 inches.
Winds: As stated above the cold front approaching today with the
jet going negative will develop a strong LLJ. This LLJ is
modeled to be in the 50-60kt range across the area. Modeled
soundings show a relatively decent steep low level lapse rates
and with heavy precipitation later today into tonight has the
potential to tap into these winds. The best chance of fully
realizing these winds will be on the Downeast coast into
portions of Interior Downeast. Given this concern for gusts
50-60mph opted to convert the High Wind Watch to a High Wind
Warning along the shore and add the next tier of Downeast zones
to the warning from 1pm-Midnight. North of these areas expecting
still significant draw down of LLJ winds especially within
precip so hoisted Wind Advisories for wind gusts to 50mph
possible. Winds will gradually relax tonight after the cold
front passes but cannot rule out some gusty W-NW on the backside
especially as we head into tomorrow but this is after a brief
break.
Tonight into early morning after the cold front passes cannot
rule out the potential for black ice to develop across the
north. Temperatures by daybreak will be rapidly falling to
around the upper 20s to low 30s so a flash freeze is possible.
This may make untreated roads (salt washed away from rain) to
refreeze right at the beginning of the morning commute. This is
most likely to impact the Route 1 & 11 corridors north of I-95
in Aroostook & Northern Penobscot counties as well as the
Moosehead Region. Elsewhere, just expecting clouds to be
breaking and temperatures falling into the 30s but staying above
freezing.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/...
The cold front will continue east through the Maritimes on Thursday
as the upper level trough axis crosses our area. Some moisture
pooled in the upper trough will work with steep lapse rates to
produce some gusty snow showers over the area, mainly across the
central and northern part of the region. Otherwise, high pressure
building to the south will combine with lower pressure to the north
to bring strong gusty cold westerly winds on Thursday with a partly
sunny sky south and a mostly cloudy sky north. High pressure
building to our south will bring a mostly clear and cool night
Thursday night. High pressure will slide off the Mid-Atlantic coast
on Friday bringing a return southerly flow behind the high. Some
moisture on the back side of the high and ahead of a new low
approaching from the Great Lakes will bring some increasing
cloudiness over the north. Downeast areas will remain sunny to
partly cloudy Thursday.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Low pressure will begin to lift north out of the Great Lakes Friday
night as the combination of the approaching low and high pressure
off to our east brings an increasing southerly breeze and warm
advection. Rain ahead of an approaching cold front will move in on
Saturday supported by divergence aloft. A strong cold front will
approach late Saturday and cross the area Saturday evening. This
front will be similar to the strong cold front moving through
Wednesday night with strong southerly winds, especially along the
Downeast coast, likely early Saturday evening ahead of the front.
Strong surface convergence associated with the front will likely
bring a band of briefly heavy rain with gusty winds followed by an
abrupt wind shift to the southwest later Saturday evening. High
pressure building into the Mid-Atlantic region will then bring a
sunny to partly cloudy day on Sunday with lighter winds. High
pressure will slide nearby to our south Sunday night then slide off
to the east on Monday with sunshine and a return southerly breeze on
Monday. The next frontal system in our fast moving, progressive and
active pattern will approach Monday night and bring a mix north and
rain south, likely again changing to rain across the rest of the
region Tuesday as an occlusion pushes through. Cold air will follow
on Wednesday with snow showers likely as low pressure slides to our
east and the upper trough builds in. Some very cold Arctic air may
begin to filter into the area from the core of the upper trough late
Wednesday into Wednesday night.
