AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
1221 AM EDT WED OCT 8 2025
SYNOPSIS
A COLD FRONT WILL PUSH OFF THE COAST TODAY. HIGH PRESSURE WILL BUILD
IN FROM THE GREAT LAKES TONIGHT INTO THURSDAY AND SLIDE SOUTH OF OUR
AREA FRIDAY INTO SATURDAY. HIGH PRESSURE WILL REBUILD TO OUR NORTH
ON SUNDAY AS LOW PRESSURE INTENSIFIES ALONG THE MID ATLANTIC
COAST.
NEAR TERM /THROUGH THURSDAY/
A STRONG COLD FRONT WILL BE ABOUT HALF WAY ACROSS OUR AREA EARLY
THIS MORNING CONTINUING TO PRESS SOUTH AND SUPPORTING A SOLID BAND
OF RAIN. STRONG CONVERGENCE ALONG THE FRONT AND MUCH COOLER AIR
UNDERCUTTING MOIST AIR OUT AHEAD OF IT WILL PRODUCE RAIN, HEAVY AT
TIMES, AS THE FRONT CONTINUES SOUTH. THE COLD FRONT WILL PUSH OFF
THE COAST LATE THIS MORNING. RAIN WILL TAPER OFF FROM NORTH TO SOUTH
ENDING DOWNEAST BEHIND THE FRONT LATE THIS AFTERNOON. WESTERN AND
NORTHERN PARTS OF OUR AREA WILL HAVE PARTIAL CLEARING WELL BEHIND
THE FRONT LATE THIS AFTERNOON.
HIGH PRESSURE BUILDING IN FROM THE GREAT LAKES WILL PUSH MUCH COOLER
AIR SOUTH ACROSS THE AREA TONIGHT INTO THURSDAY. LOWS TONIGHT WILL
FALL BELOW FREEZING IN SOME NORTHWESTERN AREAS AND DOWN TO AROUND 40
ALONG THE COAST UNDER A MOSTLY CLEAR SKY AND A GUSTY NORTHWESTERLY
WIND.
HIGH PRESSURE CONTINUING TO BUILD TOWARD THE AREA THURSDAY WILL
BRING A BLUSTERY AND COLD DAY WITH A GUSTY NORTHWESTERLY WIND. HIGHS
WILL RANGE FROM THE UPPER 40S NORTH TO THE MID 50S ALONG THE COAST.
SUNSHINE WILL MIX WITH CUMULUS CLOUDS ACROSS THE NORTH AND FAR
NORTHERN AREAS MAY BE MOSTLY CLOUDY FOR A WHILE UNDER
A STRATOCUMULUS LAYER. SOUTHERN AREAS WILL TURN OUT MOSTLY
SUNNY.
SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/
HIGH PRESSURE WILL BUILD TO THE SOUTHWEST OF THE AREA THURSDAY NIGHT
WITH MAINLY CLEAR SKIES AND LIGHT WINDS. SINCE THE HIGH WILL NOT BE
CENTERED DIRECTLY OVER US, SOME CONCERN THAT WE WILL NOT MAXIMIZE
FULL RADIATIONAL COOLING POTENTIAL. ALSO, SOME HIGHER CLOUD WILL BE
ON THE INCREASE LATER THURSDAY NIGHT. STILL, FELT CONFIDENT ENOUGH
TO LOWER THE NBM MINS JUST A BIT FOR OVERNIGHT LOWS THURSDAY
NIGHT. LOWS WILL RANGE FROM THE MID TO UPPER 20S NORTH AND UPPER
20S TO LOWER 30S FOR BANGOR AND DOWNEAST. WIDESPREAD FROST IS
EXPECTED REGIONWIDE, EVEN DOWN TO THE COAST.
HIGH PRESSURE BUILDS TO OUR SOUTH ON FRIDAY. THE RETURN SOUTHWEST
FLOW AROUND THE HIGH AND WARMER TEMPERATURE ADVECTION WILL ALLOW
HIGH TEMPERATURES TO REACH THE MID TO UPPER 50S IN MOST AREAS,
WITH A FEW 60 DEGREE READINGS NOT TOTALLY OUT OF THE QUESTION.
FRIDAY NIGHT WILL SEE HIGH PRESSURE CONTINUE TO SLIP SOUTH OF THE
REGION. EXPECT MAINLY CLEAR TO PARTLY CLOUDY SKIES AND A MILDER
NIGHT, WITH LOWS RANGING FROM THE LOWER TO MID 30S NORTH AND
MIDS 30S TO NEAR 40 NEAR THE COAST.
SATURDAY WILL BE MOSTLY SUNNY AS A WEAK FRONT COLD FRONT SLIDES
DOWN FROM THE NORTH. AFTERNOON HIGHS ON SATURDAY AHEAD OF THE
FRONT CLIMB INTO THE LOW 60S NORTH AND LOW TO MID 60S FOR THE
BANGOR REGION AND DOWNEAST.
LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/
LOOKS LIKE A MAINLY DRY PATTERN WILL PERSIST SATURDAY NIGHT AND
SUNDAY AS A RIDGE OF HIGH PRESSURE BUILDS IN FROM THE NORTH. LOW
PRESSURE WILL BE NEAR THE MID ATLANTIC REGION INTO EARLY NEXT
WEEK. LOOKS LIKE THE STRONG HIGH ACROSS THE REGION WILL REMAIN
IN PLACE AND KEEP ANY RAINFALL WITH THAT SYSTEM TO OUR SOUTH, AT
LEAST THROUGH MONDAY AND POSSIBLE LONGER. AFTERNOON HIGHS LOOK
TO BE NEAR, OR SLIGHTLY ABOVE THE SEASONAL NORMS FOR THIS TIME
OF YEAR.
