Area Forecast Discussion
National Weather Service Caribou ME
1230 AM EDT Wed Apr 2 2025

.SYNOPSIS...
High pressure builds in tonight and will remain over the area
through Wednesday. An occluded storm system approaches Wednesday
night and then passes to the northwest on Thursday. Weak high
pressure briefly returns late next week before another system
approaches from the southwest this weekend.

&&

.NEAR TERM /THROUGH TODAY/...
12:30AM UPDATE...Minor tweaks to the ongoing forecast. Mainly
clear skies across the area with breezy NW winds. Strong cold
air advection is sending temperatures down into the teens and
20s so far... A few mid level clouds over far NE Aroostook
County up near Hamlin, Van Buren and down to near Caswell. No
other changes...

Previous Discussion:
Gusty northwest winds will continue in the wake of the cold
front exiting over the Maritimes tonight. Gusty winds will
linger in the east, keeping surface temperatures a little
higher, however across the North Woods, the atmosphere will
decouple by early morning and single digits are expected for
overnight lows. Highs in the low 30s in the north are expected
for tomorrow, with highs reaching closer to 40 for Bangor and
Downeast.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...
High pressure moves east out of the area Wednesday night as our
next system approaches, bringing mixed precipitation to the
region. A warm front lifts north overnight producing overrunning
precipitation that should begin in central Maine just after
midnight. Some differences in timing still exist in the models
with the GFS being the faster solution while the Canadian, Euro,
and NAM are a bit slower. Once precipitation does begin it
should start out as snow for the first few hours with a quick
1-3 inches possible. Most areas will see a transition from snow
to sleet, then freezing rain, and eventually plain rain as
southerly flow increases throughout the day on Thursday. The
greatest freezing rain threat is in northern and central Maine
where cold air damming is expected to be a concern. This should
keep areas in the Central Highlands around freezing through the
morning. Ice accumulations are expected to be 0.1-0.2 which is
not enough to cause widespread power outages but could cause
some slippery conditions.

Precipitation works its way out of the area later Thursday
afternoon and evening. Expect some patchy fog to develop across
the region, particularly near the coast, as warm moist air
overspreads the region. The cold front passes through Thursday
night with blustery northwest flow developing that will persist
through Friday. Cannot rule out some snow and rain showers
developing across the north where soundings show enough moisture
and lift in place.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Drier conditions associated with weak high pressure Friday
night before the next system approaches the area on Saturday.
This could be another possible overrunning setup as a warm
front lifts north through New England bringing another chance
for snow and mixed precipitation. Ensembles are still expressing
considerable uncertainty in the timing and evolution of this
system so stuck with just rain and snow in the forecast for now.
However, deterministic models have been showing a cold air
damming setup so will have to watch this closely for another
icing scenario.
