Area Forecast Discussion
National Weather Service Caribou ME
148 PM EST Sun Dec 7 2025

.SYNOPSIS...
An area of low pressure tracks from northeastern New York
Sunday evening to near southeastern Nova Scotia early Monday
morning. High pressure builds in behind this system through
Monday night, then slides offshore on Tuesday. Another weak low
tracks across the Gulf of Maine Tuesday night. A stronger low
pressure system tracks from the Great Lakes Wednesday morning to
the southern Canadian Maritimes by Thursday morning, followed
by a cold front crossing the area on Thursday.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
Snow will spread across the southern tier of the forecast area
late tonight and continue over night as a weak low pressure
system passes just offshore. The low will strengthen slightly as
it moves into southern Canada, enhancing QPF over the
southeastern corner of the state. Although snowfall will be
fairly minimal for the rest of the area, including Bangor, 3 to
5 inches is expected over southern Washington County. A winter
weather advisory has been issues for this area. Behind the low,
winds will increase with high pressure building in, mainly
offshore with the northern flow. See more detail in the marine
section. As for the land, the high building in will also bring
another round of very cold air, so temperatures Monday and
Monday night will be well below normal, and below 0F in many
locations.

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
Key Messages
-Light snow accumulation Tuesday night
-Larger system approaches Wednesday with snow and rain

The high pressure system exits over the waters on Tuesday,
making for clear skies in the morning. Clouds start to move in
in the afternoon as the next low approaches. A warm frontal
boundary should stretch well to the north, switching winds to
onshore flow. For Tuesday night, with weak low pressure system
should move into the region. The onshore flow should keep temps
above zero, though in the single digits or teens across the
area. The weak low pressure system should bring some light snow
across the area with higher amounts round 2 inches in Downeast.

For Wednesday, a larger low pressure system moves in later in
the day. Warmer S flow should push temps into the 20s in the
north and upper 30s in the south. Snow is expected to be light
in the afternoon with higher amounts in the Central Highlands.
Areas south of the Central Highlands should see a mix of
rain/snow or rain.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
Key Messages
-Active period with cold single digit nighttime temperatures

The low pressure system should exit the area by Thursday,
making for warmer temps, breezy winds, and cloudy skies. Upper
level models show a fairly active extended period as the upper
level trof swings through one shortwave after another. The
further south jet stream puts the area in the left exit region,
thus a more active area. The models lose consistency towards the
end of the week due to uncertainty of the trof pattern.
