The episode as NWS CAR wrote it up.
Intensifying low pressure lifted north across New Brunswick to the Gulf of Saint Lawrence...along an occluded front...through the 7th into the 8th. Precipitation initially began in the form of rain. Cold air being drawn across the region...to the west of the low track...allowed a transition to snow during the early morning hours of the 7th. Snow...heavy at times...then persisted through the afternoon into the evening of the 7th. Warning criteria snow accumulations occurred from the late afternoon into the early evening hours of the 7th. The greatest storm totals occurred across northern and eastern portions of Aroostook county with snow totals generally 7 to 10 inches. Storm total accumulations of 4 to 6 inches occurred in a region from northern Somerset...across northern and central Penobscot...to northern Washington counties. Lesser snow totals occurred across the remainder of the region due to a longer duration of rain...along with distance from the storm track. The tightening pressure gradient with the intensifying low supported increasing winds across northeast portions of the region through the afternoon and evening of the 7th. Wind gusts of 30 to 40 mph produced extensive blowing and drifting snow with visibilities occasionally reduced to around a quarter mile or less. Hazardous driving conditions led to accidents. Blowing and drifting snow persisted through the overnight hours of the 7th into the 8th.

Area Forecast Discussion
National Weather Service Caribou ME
1254 AM EST Fri Mar 7 2025
.SYNOPSIS...
Low pressure slowly lifts northeast Friday night through
Saturday and Sunday. Weak high pressure builds in later Sunday
into early Monday. A weak low approaches later Monday, with
another one on Tuesday.
&&
.NEAR TERM /THROUGH TODAY/...
1255 AM Update: Precip has begun to stream in over the forecast
area as the next low begins to approach the forecast area. Fog
has dissipated over most of the area, becoming replaced by a
return of rain that will shortly switch to snow as temperatures
continue to drop.
Previous Discussion...
Surface low pressure sits over Quebec with occlusion draped
through the CWA this afternoon. This has brought showers mainly
to an end though cannot rule out a stray shower the remainder of
the afternoon/early evening. Triple point low develops and rides
northeast along the boundary.
As it heads north rain will spread back into Downeast late this
afternoon into early evening. By midnight likely to categorical
precip moves into the eastern portion of the area. At the same
time cold air will be coming in on west winds and as moisture
moves back to the west it will turn rain over to snow. With caa
occurring through 09z expect that entire area will be all snow,
other than coastal Washington County.
Banding is expected over northeastern sections of the area as H7
low passes. All guidance has trended west with the heavy snow as
low moves up through New Brunswick. Have issued Winter Weather
Advisory for all of Aroostook County with storm total snowfall
ranging from 3 to 5 inches. Given the performance of the models
the past day or two of runs would not be surprised to see
warning criteria amounts occur. As the low deepens over the Gulf
of St. Lawrence on Friday and mixing develops in the afternoon,
strong northwest winds will kick up with gusts to 45 mph fairly
common. Open areas will experience patchy to areas of blowing
snow, leading to whiteout conditions.
Any standing water on roadways will freeze tonight as cold air
comes crashing in, resulting in a flash freeze ahead of snow
moving in. This will bring snow covering the ice underneath and
make travel and walking dangerous in the morning.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY/...
A powerful low pressure system will move northward through New
Brunswick and towards Labrador for Friday night and Saturday.
While the steady snow will have ended by Friday evening, snow
showers will continue north and west of Katahdin. Shortwaves
rotating around the low will keep the snow shower threat going
there into Saturday. Given a wind direction of 270-290 degrees,
the greatest threat for snow showers will be in the Saint John
Valley into the higher elevations of the North Woods. Wind gusts
will be strong enough for patchy blowing snow where snow showers
are falling. Low temperatures Friday night will be in the teens
north of Katahdin, with 20s to the south. Cold air advection
will limit high temperatures on Saturday. Expect teens to lower
20s north of Katahdin, with mid 20s to lower 30s to the south.
Wind chills will likely drop below zero from Katahdin northward
Saturday morning.
The low will pull further away Saturday night into Sunday, and
weak high pressure will build towards the area. This will allow
the snow shower threat to end Saturday night. Winds will also
gradually diminish, though it will remain breezy into early
Sunday. Low temperatures Saturday night will be in the single
digits above zero in the North Woods, with teens elsewhere.
Highs on Sunday will remain in the 20s from Katahdin northward,
with lower to mid 30s south.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
High pressure will move over the region Sunday night. This will
allow for clearing skies and light winds. Some uncertainty with
low temperatures Sunday night, as high clouds may move in late.
However, potential exists for many northern areas to drop below
zero.
A series of shortwaves will then move through the area next
week. Disagreements exist among model guidance as to the track
and strength of these shortwaves, so confidence remains low. The
first shortwave looks to impact the area later Monday into
Monday night. This could produce some light snow or snow
showers. The next one will approach later Tuesday into
Wednesday, and track over or north of the Crown of Maine. Some
light snow is possible north of this low track, with dry and
mild weather to the south. A third system could impact the
region late next week, but confidence in track and timing is low
at this time.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
NEAR TERM: A brief reprieve in IFR/LIFR conditions through the
middle of the night as MVFR ceilings return and fog lifts.
However, MVFR conditions will not last long, with cigs and vis
dropping right back towards LIFR into the early morning hours as
rain switches to snow. Winds will also increase through late
tonight into the day on Friday, becoming W 15 to 20 kts with
gusts 30 to 35 kts.
Snow will begin to taper off in the afternoon, however high
winds will lead to BLSN which could prolong reduced vis beyond
the end of snow, particularly at northern terminals. LLWS likely
to develop over at least northern terminals by the evening.
SHORT TERM:
Friday Night & Saturday...MVFR/IFR at Aroostook terminals with
scattered -SHSN and patchy BLSN. VFR Downeast. W winds 10-15
kts, gusting 25-35 kts.
Saturday Night...Brief MVFR possible at Aroostook terminals
early with isolated -SHSN. Otherwise VFR. W winds 10-15 kts,
gusting up to 25 kts.
Sunday into Monday...Mainly VFR. W winds 5-10 kts. Gusts to 20
kts possible Sunday.
Monday Night & Tuesday...VFR early Monday night. MVFR/IFR late
Monday night with -SN or -SHSN possible. Mainly VFR Tuesday,
except MVFR/IFR at Aroostook terminals Tuesday PM with -SN or
-SHSN. W winds 5-10 kts.
&&
.MARINE...
NEAR TERM: Winds will begin ramping up again towards gale force
through the early morning hours. Northwest winds will gust to
gale force throughout the day with seas building to between 7
to 11 feet.
SHORT TERM: Winds will remain above Gale force on all waters
through Friday night and through Saturday. Wave heights of 8 to
11 feet are expected over the outer waters, with up to 12 feet
Friday evening. Winds diminish below Gale force on the intra-
coastal waters Saturday evening, and on the outer waters by
Sunday morning. Winds and seas subside below Small Craft
Advisory criteria on all waters Sunday night. Sub-SCA conditions
continue through Monday thanks to high pressure. Winds could
return to SCA levels Monday night into the middle of next week.
