Area Forecast Discussion
National Weather Service Caribou ME
909 PM EST Thu Dec 15 2022

.SYNOPSIS...
High pressure will ridge across the region overnight and move
east Friday. Low pressure will track into the Great Lakes
Saturday while secondary low pressure lifts to near Nova Scotia
and into the Gulf of Maine. These lows will lift to our north on
Sunday into Monday. High pressure will build toward the region
Tuesday......

.....Previous discussion:
High pressure centered north of Labrador will ridge south
across the region tonight. However, moisture trapped beneath a
subsidence inversion will support mostly cloudy skies across the
region tonight. Scattered flurries are also possible. High
pressure will exit across the Maritimes Friday. At the same
time, intensifying low pressure will track from the Mid-Atlantic
coast toward southern New England. Snow will expand, from
southwest to northeast, across the forecast area Friday in
advance of the low. Snow accumulation of up to around an inch
are possible across southwest portions of the forecast area
through later Friday afternoon. Low temperatures tonight will
range through the 20s north to the upper 20s to around 30
Downeast. High temperatures Friday will range from the upper 20s
to around 30 north, to the lower to mid 30s Downeast.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
Headlines: A significant winter storm will impact the area
during the short-term period. A Winter Storm Watch is in effect
for Central and Southern Piscatiquis County, Central and
Southern Penobscot County, and Interior portions of Hancock and
Washington Counties. Confidence is highest for warning criteria
snows in these places at this time.

Discussion:
A strengthening low pressure system will slowly track through
the Gulf of Maine towards Nova Scotia from Friday night through
Saturday. Thus, precipitation will overspread most of the area
from southwest to northeast Friday night, and continue
throughout Saturday. The exception is Northern Aroostook
County, where downsloping east to northeast winds from a high
pressure system will limit pops. Thermal profiles suggest a
mainly snow event for the region, except for Coastal Downeast
where a mix of rain and snow is forecast. Thus, held off on
issuing any winter weather headlines north of the current watch
area and along the coast due to uncertainties with precipitation
amounts and types respectively.

Breezy conditions are forecast inland with windy conditions at
the coast for Friday night and Saturday. Northeast wind gusts of
25-30 mph are expected inland, while gusts around 40 mph are
possible at the coast. Most model guidance keeps the very
strongest winds with this storm offshore, so held off on any
wind headlines for the coast at this time. Will continue to
monitor and update as needed.

The low will move slowly move further northeastward Saturday
night and Sunday. At the same time, an upper-level low will
approach the area from the west. This setup will cause
precipitation to taper to snow showers in southern areas, with a
mix of rain and snow showers at the immediate coast. Across the
North, however, the upper-level low is expected to enhance
snowfall. Much of the accumulating snowfall in Northern Aroostook
County forecast for this weekend is likely to occur during this
time. Winds will slowly diminish during this time as the low
near Nova Scotia moves away from Maine.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
By Monday, a secondary low developing over Quebec will move
south, merging with the first low to develop an inverted trof.
This trof is expected to stall over the region with the initial
low which will bring additional snow fall over the area into
next week. Accumulations could be significant with the extent of
the snowy days. A brief ridge should set up on Tuesday, then
move out by Wednesday with an approaching low. 12Z models show a
cold front moving through the region with possible snow showers
in the north. High temps should be above normal.....
