Area Forecast Discussion
National Weather Service Caribou ME
515 AM EDT Thu Apr 25 2024

.SYNOPSIS...
Low pressure will exit across the Maritimes today. High
pressure will build across the region later today into
Saturday. A warm front will approach from the southwest
Sunday and move to the Saint John Valley on Monday.
&&

.NEAR TERM /THROUGH TONIGHT/...
Surface/upper level low pressure will exit across the Maritimes
today. A disturbance rotating around the upper low will clip
the region early today. The disturbance could bring scattered
flurries to northern portions of the forecast area this morning.
Otherwise, high pressure will build across the region later
today through tonight. Expect partly/mostly sunny skies north,
sunny Downeast, today. The pressure gradient between the exiting
Maritimes low and building high pressure will support gusty
northwest winds today. Wind gusts of 30 to 35 mph are expected
through early this afternoon, then decreasing late. Mostly clear
skies are expected across the region tonight. High temperatures
today will range from around 40 to the lower 40s north, to the
mid to upper 40s Downeast. Low temperatures tonight will range
from the upper teens to around 20 north, to the lower to mid 20s
Downeast.
&&

.SHORT TERM /FRIDAY THROUGH SATURDAY/...
Upper level trof axis will be exiting east across the Canadian
Maritimes during Friday. Deep layered northwest flow of dry air
remains in place through the afternoon under mainly sunny skies.
Afternoon highs will top out around the 50 degree mark across
the north and the low to mid 50s for Bangor and Downeast.

Upper trof continues to exit to the east with rising heights as
upper ridging begins to build in. Surface high slides across
the region with mainly clear skies and light winds. Radiational
cooling conditions should allow for overnight lows falling into
the mid to upper 20s.

Upper level ridge builds east toward the region on Saturday as
surface high slides east. Expect another mainly sunny day with
milder afternoon high temperatures. Developing onshore flow
will keep afternoon highs several degrees cooler for the
immediate coast and outer islands.
&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Saturday night should remain dry as upper ridging and dry air
remains in place. Any showers in advance of a weakening short
wave and warm front from the west should hold off until later
Sunday afternoon. A cold front will then begin to move into far
northern areas later Sunday night and then tend to dissipate
across the area during Monday. Low pressure will track northeast
toward James Bay during Monday drawing a warm front toward the
region, along with the chance of late night showers. An
occluded front will cross the region later Tuesday through
Wednesday with the chance for showers, or even perhaps a
steadier rain. Afternoon high temperatures will tend to average
a bit above normal for this time of year.
&&

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
NEAR TERM: Local MVFR conditions possible across northern areas
this morning with scattered flurries. Otherwise, VFR across the
region today through tonight. Northwest winds 10 to 20 knots
with gusts up to around 30 knots through early this afternoon,
then decreasing to 10 to 15 knots with gusts up to 25 knots
later this afternoon. Northwest winds 5 to 10 knots tonight.

expected. NW wind 10 to 15 kt on Friday, light and variable
Friday night, then becoming light SE Saturday and Saturday
night.
