What happened

The episode as NWS CAR wrote it up.

Powerful low pressure rapidly intensified across the Great Lakes from the 22nd into the 23rd...tracking to Quebec province during the 24th. A secondary low developed across western New England during the 23rd from the occluding Great Lakes low. The secondary low then drew an occluded front across the region through the 23rd into the early morning hours of the 24th. This system brought multiple impacts to the region including very strong winds...heavy rain...thunderstorms...coastal flooding and stream flooding.|A very strong low level jet developed in advance of the occluded front. Winds increased through the 23rd. The strongest winds occurred from the afternoon of the 23rd into the early morning hours of the 24th. East to southeast winds were sustained at 25 to 35 mph...with gusts generally 60 to 70 mph. However...localized gusts up to around 80 mph also occurred. An 80 mph gust was measured near Eastport...with a 78 mph gust at Trescott...both in coastal Washington county. A 77 mph wind gust was reported at Frenchville in northern Aroostook county. The winds caused extensive tree damage with trees uprooted and snapped. The falling trees brought down power lines and utility poles leading to extensive power outages. Power outages peaked during the early morning hours of the 24th when around 55000 customers were without power. Roads were also blocked by fallen trees. A line of thunderstorms accompanied the occluded front across western portions of the region which also locally enhanced winds. The gradient winds and thunderstorms led to several hundred trees uprooted or snapped around the Lily Bay area of central Piscataquis county. The winds also tore the roof from a trailer in Caribou and blew a tractor trailer off the road near Fort Fairfield...both in northeast Aroostook county.|Strong onshore winds and large breaking waves led to coastal flooding along portions of the Downeast coast during the 23rd. The greatest impacts occurred around the time of the late morning high tide. The storm surge at the time of high tide was up to around 2 feet at some locations along with large breaking waves. Several roads and causeways were closed due to overwash...water covering the roads along with deposited debris. Closures included Seawall Road...Moore Road and Hulls Cove Road all in Hancock county. Some roads and causeways were able to re-open after waters subsided and debris cleared. Plows were needed to remove debris from some roads. However...some roads and causeways were damaged or partially washed out leading to more extensive damage. Piers in several harbors were also damaged to varying extents along with beach erosion. Reverse tidal flooding up the Penobscot River led to minor flooding of park land along the Kenduskeag stream during the late evening high tide.|Abundant moisture was also drawn north across the region in advance of the occluded front leading to heavy rain. Warm air was rapidly drawn north. This led to limited wintry precipitation across central and northern areas. Snow accumulations...before the transition to rain...were generally an inch or less across central and northern areas with 1 to 3 inches across extreme northwest areas. Ice accumulations were generally a tenth of an inch or less. The heaviest rains occurred through the afternoon into the evening of the 23rd. Rainfall totals across central and Downeast areas generally ranged from 1.50 to 2.50 inches...with local totals approaching 3.00 inches. Rainfall across northern areas generally ranged from around 0.50 inch to 1.50 inches. The warm temperatures led to melting of the snow pack which released additional water for runoff. Clogged storm drains helped lead to ponding of water in some areas. Ponding also occurred in some low lying areas. The greatest impacts occurred across portions of central and southern Piscataquis county where several roads and culverts were damaged or washed out and numerous basements were also flooded.|A flash freeze also occurred in the wake of the occluded front during the morning of the 24th with rapidly falling temperatures. Wet roads and standing water rapidly froze leading to slippery road conditions.

.SYNOPSIS...
Strong low pressure lifting across the Great Lakes will draw an
occluded front across the region later today into Saturday
while the low tracks well northwest across Ontario and Quebec
provinces. The low will track northwest of the region Sunday.
An upper level disturbance remains to our north through Tuesday
while high pressure at the surface builds in by midweek.

.NEAR TERM /THROUGH TONIGHT/...
Update...
Precipitation is expanding across the forecast area. Have
updated to adjust for current conditions, mostly temperatures.

Previous Discussion...
...Damaging Wind and Rain Storm today into early Saturday
Morning...
...Significant Snowpack Loss and Flooding Likely...
...Wintry Mix today will Impact Holiday Travel...

No changes to any headlines.

Pattern...Intense low pressure will lift across the Great Lakes
to western Quebec province today, while a secondary low lifts
across western New England drawing an occluded front across the
region later today and tonight.

Precipitation...Precipitation will expand across the remainder
of the region this morning. Precipitation will be heavy at times
later this morning into the evening. Based on critical
thicknesses, expect snow will transition to a wintry mix and
eventually rain across northern and central areas through the
afternoon and evening in advance of the occluded front. An
interval of patchy blowing snow is also possible across
northeast areas later this morning with the snow and increasing
winds. Across interior Downeast areas, snow or a wintry mix will
transition to rain this morning. Expect mostly rain along the
Downeast coast today. An isolated thunderstorm is possible
Downeast later this afternoon through early tonight. Total snow
accumulations across northwest areas through tonight will range
from 3 to 5 inches, with 1 to 3 inches across the remainder of
northern Maine and around an inch across central areas. Ice
accumulations of up to a quarter inch are possible across
northwest areas, with up to around a tenth of an inch across the
remainder of northern and central portions of the forecast
area. However, more persistent cold air damming could allow for
greater ice accumulations. Cold air will rapidly return in the
wake of the occluded front tonight allowing for a transition
back to snow or snow showers. The precipitation should then
taper to snow showers overnight. The rain is falling on snowpack
and will create hydrological issues (see Hydrology section
below for more details).

Winds...Ahead of the occluded front and triple point low a
powerful low level jet will cross the region. This will place
a core of 80- 90 knot winds between 925-850mb over the area
this afternoon into the evening. We will likely mix down a
large portion of this jet but the low level lapse rates may
still be enough to prevent all of the jet mixing down. Heavy
rain and the disruption of the inversion with the frontal
passage could help mix stronger winds to the surface. Boundary
layer wind gusts could approach 50-60 knots across the area.
These strong east/southeast winds will likely cause significant
impacts to trees and result in scattered to widespread power
outages.

Flash Freeze Likely...Temperatures will rapidly fall below
freezing in the wake of the occlusion, supporting a flash freeze
of wet surfaces. Rain will have washed much of the salt residue
from the roads and other treated surfaces. This will result in
surfaces quickly becoming slippery without sand/salt treatment.
In addition, significant runoff from melting snow will freeze on
surfaces creating hazardous travel conditions.
&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
During the day Saturday the occluded front that passed through
the area Friday Night will continue to push Northeast through
the Canadian Maritimes with the powerful parent stacked low up
in Central Quebec. Strong cold air advection will result in
temperatures mainly holding steady in the upper teens to low 20s
north and low to mid 20s south with perhaps a few 30s on the
islands. Overall, not expecting much of a diurnal influence
given the strong cold air advection and low sun angle (solar
noon angle of 19.8-22 degrees). In the morning expect some snow
showers across the north and continuing along the Downeast coast
with persistent low-level moisture and upper level energy
pivoting over. Snow showers being persistent and high ratios
with much colder air and decent conditions in the DGZ cannot
rule out 1-2 inches in coastal Hancock into coastal Washington
County. Those snow showers will continue into Sunday in the
coastal Washington County communities with additional snowfall
up to 1-1.5 inches. When all said and done 1-3 inches seems
reasonable with 2-3 inch readings in places like Cutler,
Whiting, Pembroke, Eastport and Lubec. Winds will remain gusty
Saturday into Sunday in the 15-25mph range with higher gusts
along the Downeast coast possible up to 35mph. Wind chills
during the day in the single digits north, teens south and wind
chills at night around 0F north and single digits south. Air
temperatures on Sunday AM in the low to mid teens south and
single digits north. Highs on Sunday once again mid 20s south
with low 20s north. Snow showers Downeast finally end by Sunday
evening.
&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
The NAO is turning positive and will increase to +0.5 to +1SD
based on the latest model trends with the PNA turning positive
as well in the +0.25 to +0.5SD range. Intially to start the week
we remain under the influence of the 500mb long wave troughing
that produced the large storm system. Expect the long wave
trough to control through Tuesday evening. Expecting partly
sunny skies south and mostly cloudy skies north with low-level
moisture trapped under mid level inversions. Cannot rule out
some flurries or snow showers on Tuesday as a 500mb shortwave
works through but as of right now it appears to be too dry to
produce precip. Mon-Tue highs in the teens to 20s north with mid
to upper 20s south. Lows each morning in the single digits to
teens from north to south. Wednesday a large high pressure will
track through the Southeastern US states and then off the
Southeast coast into the Atlantic. This high will set up a
warming trend into late next week with temperatures returning
above freezing for highs by late week.
&&

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
NEAR TERM: Downeast terminals dropping to IFR and remaining
there throughout the day. LIFR vsbys in heavy rain possible late
this morning into early afternoon. Expected conditions to
improve to MVFR after 01z. ESE winds 20-30kts gusting to between
50-60kts today.

Aroostook terminals diminishing to MVFR by mid-morning and then
IFR early this afternoon. Remaining IFR into this evening. Light
snow transitions to a wintry mix of -fzrasn before transitioning
to rain late this afternoon. Rapidly falling temps between
06-12z tonight will cause runways to instantly freeze any
standing water on them.

LLWS at all terminals thru 04z tonight.

SHORT TERM: Sat...VFR/MVFR cigs. Slight chance snow showers at
BHB. S-SW winds 10-20kts w/ higher gusts to 30kts at BHB only.

Sun...VFR/MVFR cigs. Slight chance snow showers at BHB. S-SW
winds 10-20kts.

Mon...VFR south terms, VFR/MVFR cigs north terms. W winds
10-15kts.

Tue...VFR/MVFR. W winds 5-15kts.
&&

.MARINE...
NEAR TERM: A Storm Warning remains in effect for all the waters
today into tonight. Rain today into tonight, tapering to
snow/rain showers late. Isolated thunderstorms possible later
this afternoon through early tonight.

SHORT TERM: Winds...W-SW Gales expected through Sun evening
across the waters. Gales will fall to SCA gusts over the Intra-
Coastal in the morning hours of Sun. SCA wind gusts expected
through Mon Eve over the waters before falling below SCA by
early Tue AM. Winds remain below SCA through midweek with the
next potential SCA gust period by Fri.

Waves...Sat will feature S swells 7-11ft close to shore with
12-18ft over the outer waters slowly subsiding all day. The
period will be 10-12sec during the day. Sat night expect those S
swells to continue every 10-12sec but subsiding to 10-12ft
offshore and 6-9ft near the coast. These waves continue to
slowly subside Sun but still remaining 6-10ft every 9-11sec. By
Mon the S swells finally fall to 3-6ft every 8-9sec. Waves fall
to 1-3ft from Tue into Thu before building 2-4ft by late week.
&&

.HYDROLOGY...
High confidence in hydrological impacts from the rain on snow
event today through the Holiday Weekend. The storm system is
poised to produce a widespread 1-2 inches of rain with locally
higher amounts to 3 inches. The heaviest rainfall is expected
from this afternoon through this evening with the potential of
1-2 inches falling in less than 6 hours across southeast upslope
of the Longfellow Mtns into portions of the Central Highlands
and the Bangor Region to Downeast Maine. Much of this rain will
fall into the Piscataquis and Penobscot River basins.

Snow water equivalents (SWE) amounts across the area are generally 1-
3 inches, highest across the Central Highlands into northern
Aroostook County. Temperatures will be climbing into the mid-upper
30s across the North and into the upper 40s across Downeast Maine
and the Bangor Region. Dewpoints should rise to within a few degrees
of the air temperatures. These high temperatures/dew points combined
with strong gusty winds will enhance the rate of snowmelt resulting
in significant snowpack loss and compression. The snowpack across
the North Woods into the rest of the Crown has temperatures of 25-
30F based on latest satellite measurements. Across the Central
Highlands into the Greater Bangor area to Interior Downeast the
snowpack temperatures are in the 28-32F range. The snowpack across
the north will absorb the majority of the rainfall, compact and only
discharge small amounts of the water content. In southern areas it
is highly likely to see complete snowpack loss and discharge of the
water content. The snowmelt across the Highlands into Downeast areas
will be impacting the Piscataquis, Penobscot Rivers and smaller
streams and creeks could result in runoff of 0.75-2 inches of water
strictly from snowmelt. Much of the water melted across the entire
forecast area will run off due to the top layer of the ground being
frozen, especially in areas with deeper snowpack. The rapid nature
of the snowmelt combined with heavy rainfall over frozen grounds
could lead to flash flooding, especially of normally fast responding
streams and known poor drainage areas.

Nearly all rivers and streams across the area are running Above
Normal to Much Above Normal (76th-90th+ percentile) with limited
storage capacity. River ensemble forecasts continue to highlight the
potential for the Piscataquis and Penobscot River basins to exceed
bankfull and see minor to potentially moderate flooding. This will
include potentially significant impacts on the smaller streams and
creeks in these basins. The lack of extensive ice cover over the
rivers means it should not be a concern for the flooding. Confidence
in the magnitude of flooding is increasing but exact impacts wont be
known till rainfall begins and rivers rise. Rivers with the best
chance of seeing flooding will be in the Piscataquis & Penobscot
River basins and the smaller Downeast basins. Any river flooding
will likely be ongoing into the holiday weekend, potentially
impacting travel and residents/businesses in flood prone areas.

As always, localized flooding due to clogged culverts and drains
will be possible given the snowmelt and predicted rainfall.
Ponding on roads due to poor drainage is also a concern.
&&

.TIDES/COASTAL FLOODING...
Coastal Flood Warning continues for both high tide cycles on today.
The higher astronomical tide is this morning near 10am. This tide
will be accompanied by a storm surge in excess of 2 feet for coastal
Hancock County and a bit less further east along the Washington
County coast. This should be a sufficient water level to cause
potential tidal flooding around Kenduskeag Plaza in Bangor and
impact the Deer Isle Causeway with minor flooding. Minor flooding
can also be expected around the causeway in Machias. Wave runup will
likely cause small rocks to be deposited on exposed coastal roads
such as Seawall Road on Mt Desert Island and on the Schoodic
Peninsula. Coastal erosion for locations such as Rogue Bluffs can be
expected.

The peak surge for eastern Maine actually occurs a few hours before
the evening high tide near 1030pm. The astronomical tide is also a
foot and a half lower. However, the surge up the Penobscot River
nearly offsets that and more. Therefore, minor flooding around
Kenduskeag Plaza continues as a concern for this time. The other big
concern for the evening tide is wave runup. For this tide, both wave
height and period increase significantly and will push well into the
bays and inlets along the coast. Splash-over with rocks may close
numerous exposed coastal roads and potentially impact the Deer Isle
Causeway again.

As the winds change direction and decrease later in the night, surge
diminishes. However, another high astronomical tide occurs Saturday
morning before 11am. That combined with long period seas up to 14
feet means that wave runup and erosion will likely cause issues for
a third tide. Will handle this tide with a separate headline as
necessary after evaluating results from todays tides.
