Area Forecast Discussion
National Weather Service Caribou ME
104 PM EST Thu Feb 11 2021

.SYNOPSIS...
Canadian arctic high pressure will slowly build across the
region through Saturday. Low pressure will track well south of
the region today into Friday. Another low is expected to track
well south of the region Sunday into Monday.

&&

.NEAR TERM /THROUGH TONIGHT/...
1:04PM UPDATE...CAA clouds have developed with enough moisture
aloft and upper level vorticity moving overhead. Also have seen
light snow showers develop in the St. John Valley below the
radar beam. Looking north from the office we can see the
convective nature to the clouds with mostly Virga but some
snowflakes making it to the ground. Added the mention of
flurries in spots where snow is able to make it to the ground.
The main story today is the winds continue to make it feel much
colder with wind chills around 0F. Those winds have been causing
some patchy blowing snow in portions of Aroostook county across
the farmlands/fields as observed on numerous webcams. Opted to
add patchy blowing snow to the grids as winds continue to gust
to 25mph in many spots. The backdoor boundary and associated
upper level trough is moving over the Gaspe Peninsula and will
arrive this evening. No other major changes were made to the
forecast.

Previous Discussion...
The main weather element today will be breezy conditions. This
is associated with a tightening pressure gradient between low
pres to the northeast and high pres over central Ontario. Wind
increases quickly as mixing to about 850mb occurs, a fairly deep
mixed layer for mid-winter. Luckily, most locations will have
recovered a little from overnight lows before winds pick up.
This will transition out of the Wind Chill Adv smoothly.
Conditions remain dry minus a few flurries working their way
into the St John Valley late this afternoon and evening.

Backdoor front approaches from the north tonight, bringing more
widely scattered snow showers to the St. John Valley. QPF is
generally limited, so accums less than a inch are anticipated
where sn showers are most prominent. With clouds moving in
across the north, much of the region should take a break from
minus teen overnight lows. Clear spots, mainly Bangor Region and
Downeast, will see temps dip into the negative single digits for
lows. However with winds only slackening a little into the
overnight hours, kept these temps closer to 0.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Low pressure will remain near Newfoundland Friday through
Friday night while high pressure gradually builds east toward
the region. Generally expect mostly cloudy skies along with a
slight chance/chance of snow showers across the north and
mountains Friday into Friday night. Generally expect partly
cloudy skies Downeast Friday into Friday night. High pressure
will cross the region Saturday with mostly/partly cloudy skies
north, partly cloudy Downeast. Low pressure will exit the
Mid-Atlantic coast Saturday night. Clouds will increase early
Saturday night. The northern edge of the precipitation shield
from the low could bring a chance of snow to the region later
Saturday night. High temperatures Friday/Saturday will remain at
below normal levels.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The Mid-Atlantic low should track well south of the Gulf of
Maine Sunday. Could still have a chance of snow early Sunday,
with a chance of snow showers during the afternoon. Otherwise,
skies will remain mostly cloudy Sunday. An upper level
disturbance could bring a slight chance of snow showers early
Monday. Otherwise, generally expect partly cloudy skies
Monday with high pressure building toward the region late. High
pressure crosses the region early Tuesday. Another low is
expected to track northeast later Tuesday, though the exact
track, intensity and timing remain uncertain. Impacts from this
potential low will be dependent on the eventual track and
intensity. At this time, the better snow chances Tuesday appear
to be across Downeast areas with lesser chances across the
north. The system exits across the Maritimes Wednesday.
Dependent on the timing of the low, could still have a chance of
snow early Wednesday with precipitation then tapering to snow
showers. Temperatures will remain at below normal levels Sunday
through Tuesday, with near normal level temperatures Wednesday.
