Area Forecast Discussion
National Weather Service Caribou ME
717 PM EDT Fri Mar 22 2024

.SYNOPSIS...
Low pressure approaches Saturday, crosses the Gulf of Maine
Saturday night, then exits across the Maritimes Sunday. High
pressure crosses the region Monday through Tuesday. A warm front
crosses the region Wednesday.

&&

.NEAR TERM /THROUGH SATURDAY/...
7 PM Update...Forecast remains on track with some high clouds
across the south and a clear sky over the north. Other than some
minor adjustments to temps, no changes were needed.

High pressure remains in control of the weather through the rest
of the afternoon and this evening. This will make for dry
conditions and diminishing winds. Low temperatures tonight will
range from the single digits above zero in the North Woods to
the lower 20s at the Downeast Coast.

Attention turns to a powerful storm that will impact Northern
and Eastern Maine beginning early Saturday morning. This system
will track up the Atlantic seaboard on Saturday and impact
Northern and Eastern Maine into Saturday night. This system will
have a connection to the tropics, so there will be lots of
available moisture. There will be multiple significant hazards
with this system.

Thermal profiles will be cold enough for precipitation to begin
as snow everywhere. Expect snow to break out from around
Greenville to Bucksport around or just before daybreak Saturday.
The snow will spread northeastward and reach the Saint John
Valley by the early afternoon. Models have trended colder
compared to previous runs. Thus, areas north of about Route 9
will remain snow, which will become heavy at times. Winter Storm
Warnings will go into effect Saturday morning for these areas.

Southeasterly winds will bring in warmer air south of about
Route 1 for Saturday afternoon, allowing precipitation to mix
with and change to rain there. Between Route 1 and Route 9, a
zone of mixed snow, sleet, and freezing rain will develop late
Saturday afternoon. This will be due to warm air moving in
aloft, but temperatures remaining cold at the surface. This mix
could reach Bangor, but it will be close based on current
guidance. A small shift in the transition zone will mean
significant differences for snow or ice accumulations, so will
have to monitor the exact progression.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
Low pressure will track across the Gulf of Maine and southeast
portions of the forecast area early Saturday night, reaching
the Gulf of Saint Lawrence late. Precipitation will be heavy at
times across the region early Saturday night, then diminish
late in the wake of the system. Based on critical thickness
values, expect snow across northern and central portions of the
forecast area. Snowfall rates could exceed 2 inches per hour
Saturday night into the early morning hours of Sunday. Snow or a
wintry mix is expected across interior Downeast areas early
Saturday night, with mostly rain along the Downeast coast.
However, uncertainty still exists regarding the inland extent of
the coastal front which would impact precipitation types.
Colder air will be drawn across the region in the wake of the
low. This will allow the wintry mix and rain to transition back
to snow Downeast before diminishing late. Storm total snow
accumulations across northern and central areas will generally
range from 16 to 21 inches. Locally greater totals could occur
with more persistent snow bands. Slightly lower snow
accumulations will occur across extreme northwest areas furthest
from the storm. Storm total snow accumulations across interior
Downeast areas will generally range from 10 to 16 inches, with
the lower totals closer to the coast where mixed precipitation
is more likely. Snow accumulations along the Downeast coast will
generally range from 4 to 6 inches, with the lower totals
closer to the immediate coast. A wintry mix of snow, sleet and
rain is also expected along the Downeast coast though amounts
are uncertain. Gusty winds will allow for blowing snow Saturday
night into Sunday. Could still have a slight chance/chance of
snow showers early Sunday along with partly sunny/mostly cloudy
skies. High pressure then builds toward the region later Sunday
with mostly/partly sunny skies. High pressure then ridges across
the region Sunday night through Monday. Generally expect partly
cloudy skies Sunday night through Monday. Temperatures will be
at slightly below normal levels Sunday/Monday.......
