Area Forecast Discussion
National Weather Service Caribou ME
1258 PM EST Wed Dec 4 2024

.SYNOPSIS...
Low pressure will rapidly approach from the northwest today and
cross the area Thursday. Low pressure then deepens over the
Maritimes on Friday while ridging builds over the forecast area
on Saturday. A weak low pressure system approaches the region
Sunday.

&&

.NEAR TERM /THROUGH THURSDAY/...
1255 PM Update (MS):
Refreshed the forecast given the latest trends in observations
and 12z guidance. Snow ratios were reduced slightly for the
event due to the winds, reducing amounts slightly in some spots
across the north. However, the overall changes are minor and the
forecast remains on track. Wind gusts were also increased along
the coast and over the waters for late tonight into early
Thursday morning due to the forecast low level instability
during the transit of the low level jet.

Previous Discussion...
The large clipper system will move across Quebec and cross into
the region today and tonight, then exit the region on Thursday.
For today, the approaching clipper will switch winds from light
and variable to SSW and breezy by the afternoon. Upper air
model soundings indicate a layer of low clouds this morning in
the north and clear skies in the south. If mid level dry air
moves into the north, then expect some breaks in the clouds for
the afternoon. Temps will be in the upper 20s.

By tonight, high res models show a quicken of the system from
the previous forecast. Thus the onset for precip has increased
by about 2 hours. Increasing SW flow will bring a warm airmass
into the region, creating an antidiurnal pattern for the night.
The main question for tonight is how far north the warm nose of
the airmass will progress. As of this update, the rain/snow line
will begin along the Downeast coast after sunset, then
gradually move north, reaching Bangor Region after midnight.
Expect very little progression northward of the rain/snow line
into Thursday morning.

For the north, the main concern will be the snow rates as the
occlusion boundary moves into the region after midnight and the
breezy winds creating blowing snow. As of this update,
increasing SW flow will create higher snow rates up to 1 inch
per hour along the Central Highlands. Snow rates of up to 0.5
inches per hour in the North Woods, St John Valley, and central
and southern Aroostook. In addition, gusts are expected to reach
up to 35 mph in the north, causing the falling to become
blowing snow. Expect reduced visibility for the Thursday morning
commute.

By Thursday, the rest of the occlusion will push through the
region, making for continued rain in the south and snow in the
north. Some areas in the north could still see snow rates up to
0.5 inches per hour for the later morning commute. The good new
is high confidence of the center of the clipper moving into the
region by the afternoon. This will decrease winds and precip,
though not completely stopping either. As the occlusion starts
to exit, a cold airmass behind the system will start slowly
decreasing temps with the sunset. This will change all precip
over to snow for the evening. Impacts for this system will be
travel difficulties and isolated power outages.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
As the low pressure system exits to the east, the pressure
gradient aloft will begin to tighten once more, leading to high
winds that could mix down to the surface and produce strong
gusts. This, coupled with high snow ratios (approaching 20:1) with
any wrap around moisture behind the low which could result in
fluffy snow consistency, may result in patchy blowing snow
through the night Thursday night over the Crown of Maine.
Additionally, strong wind gusts 35 to 40 mph could result in
isolated power outages throughout the entire forecast area,
including down through the coast.

These strong westerly winds will quickly advect cold air into
the region, with temperatures near steady or even falling
slightly through the day on Friday. High temperatures on Friday
may only lift into the low to mid 20s.

Winds will gradually decrease late in the day on Friday into
Friday night as a ridge of high pressure moves into the area and
the pressure gradient aloft begins to relax. Should winds
decrease and skies clear enough behind the rapidly exiting
system Friday night, surface decoupling may lead to temperatures
plummeting towards zero through the forecast area, resulting in
the coldest night of the season so far. Lows could stall in the
mid to upper single digits above zero or, should conditions
clear out quickly enough, may fall to right around zero,
particularly over the North Woods or in any typical colder
valleys of the north. Since these very cold temperatures will
occur shortly after strong wind gusts sweep across the forecast
area, be prepared with a safe alternate heat source on hand in
case of lingering power outages.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A narrow ridge of high pressure should remain over the area
Saturday into Saturday night, and colder than average
temperatures may continue with highs on Saturday only lifting
into the upper teens to lower 20s. For Saturday night, two
solutions are possible: an approaching clipper system could
produce increasing cloud cover through the night, along with
some early snow showers, and low temperatures may be comparable
to Friday night. However, if the ridge of high pressure runs
into any sort of blocking pattern from the previous low pressure
system deepening into the North Atlantic, skies could remain
clear for longer into the night, and coupled with light winds,
another night of radiational cooling could lead to temperatures
falling to around zero across the north, to potentially below
zero in the North Woods and any other typical colder valleys of
the north.

A weak clipper system may push through the forecast area Sunday,
bringing another round of snow showers, but accumulations are
likely to be much less than the previous clipper system as the
Sunday system may be more moisture starved, and also be a quick
mover. A generally unsettled pattern may persist heading into
early next week, as a deep, elongated upper level trough begins
to approach from the west, setting up a favorable pattern for
several more shortwaves to push into the region.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
NEAR TERM: MVFR/VFR conditions today in the north and VFR in
the south. For tonight, MVFR conditions developing for all
terminals due to low cigs and vsby due to snow in the north and
rain in the south. Possible IFR/LIFR in the north due to higher
snowfall rates. LLWS beginning around midnight at most terminals.
SE winds 5-15 kts, increasing to 10-20 kts late, except higher
winds and gusts expected at BHB and other coastal airports.

By Thursday, MVFR/IFR conditions in low cigs and vsby due to
snow in the north and rain in the south. All terminals become
snow by later afternoon. SE winds 5-15 kts early, then switching
to WSW by the afternoon.

SHORT TERM:
Thurs night...Terminals from KMLT and KHUL south will improve to
VFR after early rain/snow showers end, while terminals from KPQI
north remain MVFR/IFR with scattered snow showers. Increasing W
winds 10 to 20 kts with gusts 25 to 35 kts.

Fri...Improving towards VFR across all terminals. W winds 10 to
20 kts gusting 25 to 35 kts, with LLWS possible.

Fri night - Sat Night...VFR across all terminals. W winds 5 to
10 kts.

Sun...Deteriorating to IFR or lower with light snow. SW winds
shifting S at 5 to 10 kts.

&&

.MARINE...
NEAR TERM: Winds and seas remain below SCA conditions today.
Winds and seas increase tonight with winds reaching gale force
by midnight. A Gale Warning has been issued for tonight. A few
gusts to storm force are possible (roughly 50 percent chance)
for a few hours between 10-16z Thursday. A lull will then begin
late Thursday morning where winds will decrease, however,
decided to keep the Gale Warning due to winds increasing again
by late Thursday evening.

SHORT TERM: Gale conditions are likely to continue across the
waters through the day on Friday, while seas sit around 8 to 11
ft. Cold W to NW winds over waters that remain mild in
temperature may lead to convective snow showers over the waters
Friday into Friday night, which could limit visibility below 3
miles at times. Winds and seas will gradually decrease to small
craft advisory levels into the weekend.
