The episode as NWS CAR wrote it up.
Overrunning snow accompanied a warm front crossing the region, from late on the 2nd into the 3rd. Snow began during the late evening of the 2nd...persisting through the morning of the 3rd...then ending during the afternoon. Maximum snow accumulations across west-central and portions of Downeast Maine ranged from 3 to 5 inches. Snow accumulations across the remainder of the region ranged from 2 to 3 inches.

Area Forecast Discussion
National Weather Service Caribou ME
640 PM EST Sun Feb 2 2025
.SYNOPSIS...
A weak warm front lifts into the area late tonight followed by
an occluding front Monday night. High pressure slowly returns
Tuesday through Wednesday before another low pressure
moves into the area on Thursday.
&&
.NEAR TERM /THROUGH MONDAY/...
6:40PM Update...KCBW & KGYX radar echos showing a batch of
mainly virga moving NE through the State of Maine this evening.
Dew point depressions remain around 10-15 degrees with this very
dry boundary layer. Slowly the boundary layer will moisten up
through the evening as a warm front gradually lifts towards
Maine. Expecting light snow to develop late evening into the
overnight once dew point depressions become less than 5 degrees.
Air temperatures will remain rather steady or fall a few
degrees with the increasing cloud cover and lower cloud bases.
Expecting temperatures generally 10-15F across the CWA with a
few spots in the North in the 5-10F range. Winds generally light
and variable will be turning S-SSW in response to the warm
front lifting north. Snow overnight generally will be light and
fluffy and begin to accumulate rather quickly once the snow gets
underway. Slick travel is expected to develop overnight into
the Monday AM commute. Given the long duration and light
snowfall the need for headlines is not required at this point
but messaging in HWO and social media for slick commutes.
Previous Discussion...
A large occlusion located to the north will swing a warm front
through the region tonight. Snow is expected to begin early
tonight in the west, then spread to the east before midnight.
Weak S flow with the system will push precip band north. Due to
the upsloping in the Central Highlands, the majority of the snow
will remain along the higher terrain. However, typical warm
front bands will bring some localized high snow amounts across
the region with bands in the south tonight and bands in the
north by Monday morning.
By Monday, snow will continue with the higher amounts moving to
the NE. As the frontal boundary exits by the afternoon, the dry
slot will move in causing snow to dissipate and temps will start
to increase with the S flow. High temps of low 30s across the
region, except along the coast where temps will reach into the
upper 30s.
&&
.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
A cold front will enter the forecast area Monday night, crossing
through the forecast area through the night. This front will
bring another quick additional 1 to 3 inches of light snow over
the area before exiting to the east and drier air returning
behind the front. That said, the speed at which the front moves
through is still a bit uncertain. Many global deterministic
models move the front through more quickly, while hires guidance
suggests a later start and slower progression. The answer will
lie in how quickly the parent low pulls northeast and away from
the area, with a slower occlusion to the parent low resulting in
a slower progression of the cold front.
High pressure will build in behind the cold front into the day
on Wednesday. Temperatures will fall back below seasonal
averages with cold air advection pulling high temperatures into
the lower teens across the north and around 20 Downeast. With
cold air in place and continued winds under the tightened
pressure gradient between the departing low and the incoming
high, wind chills could approach 20 below in the north early
Wednesday morning, and approaching 10 below Downeast during this
time.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
The ridge of high pressure will continue to slide eastward into
the second half of the week, allowing for a low pressure system
to move into the New England region from the west. With cold
temperatures remaining well established, this system is expected
to be all snow for most of our forecast area on Thursday, aside
from some rain that could mix in along the coast. The extent at
which warm air moves into the Coastal Downeast area and allows
for a switch to rain will depend on subtle shifts in the low
track. Model agreement is quite good in the track of this storm,
leading to likely accumulating precip throughout northern and
eastern Maine. With west to northwesterly winds under a
tightened pressure gradient aloft in the wake of this storm,
some plumes of snow showers could generate off the St. Lawrence
on Friday, leading to additional light snowfall across the north
through Friday afternoon.
A narrow ridge of high pressure will return on Saturday, though
this high pressure could be brief as another storm may approach
the area this weekend. Timing and track uncertainties remain at
this point in the forecast, with the CMC taking the low furthest
south, and the ECMWF bringing the low across the center of the
CWA. However, this system is shown across all guidance, and will
continue to be closely monitored over the next several forecast
cycles.
