AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
649 PM EDT SAT NOV 1 2025
SYNOPSIS
HIGH PRESSURE BUILDS IN THROUGH THE REST OF THE WEEKEND WITH
SEASONABLY COOL TEMPERATURES. A SERIES OF SHORTWAVE TROUGHS MOVE
THROUGH NEXT WEEK, BRINGING GENERALLY COOL AND AT TIMES
UNSETTLED CONDITIONS.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
LITTLE CHANGE TO THE GOING FORECAST FOR THE REST OF THE EVENING
HOURS. CLOUDS WILL CONTINUE TO GRADUALLY DISSIPATE DOWNWIND OF
THE MOUNTAINS. WINDS WILL ALSO DECREASE OVERNIGHT.
PREVIOUSLY...
HIGH PRESSURE CONTINUES TO BUILD INTO NEW ENGLAND THROUGH THE
OVERNIGHT HOURS. SCATTERED RAIN AND SNOW SHOWERS ACROSS THE
HIGHER TERRAIN GRADUALLY DECREASE IN COVERAGE THROUGH THE
OVERNIGHT HOURS AS THE HIGH BUILDS IN. WINDS ALSO STEADILY EASE
THROUGH THE OVERNIGHT HOURS, DROPPING OFF MOST QUICKLY THROUGH
THE EVENING. WITH THE COLDER AIRMASS IN PLACE, LOWS DROP INTO
THE 20S IN MOST SPOTS TONIGHT, WITH LOWS AROUND FREEZING ALONG
THE COASTLINE.
SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/
TOMORROW LOOKS TO BRING SIMILAR TEMPERATURES TO TODAY, BUT WITH
LESS WIND AND MORE SUNSHINE, ALLOWING IT TO FEEL WARMER THAN
TODAY. THE HIGH PRESSURE CENTER CROSSES SOUTH OF NEW ENGLAND
DURING THE DAYTIME, WITH THE RIDGE AXIS MOVING THROUGH THE AREA.
SUNDAY NIGHT LOOKS SLIGHTLY COOLER THAN TONIGHT AS MORE
RADIATIONAL COOLING IS EXPECTED. LOWS DROP INTO THE 20S AGAIN
ACROSS THE INTERIOR, AND TO NEAR 30 ALONG THE COAST. OTHERWISE
THE NIGHT LOOKS QUIET AS THE HIGH PRESSURE CENTER DRIFTS EAST OF
NEW ENGLAND.
LONG TERM /MONDAY THROUGH SATURDAY/
KEY MESSAGE: AN ACTIVE AND PROGRESSIVE PATTERN WILL BRING
MULTIPLE CHANCES OF SHOWERS THROUGH THE LONG TERM PERIOD.
AMOUNTS SHOULD GENERALLY BE LIGHT.
FORECAST DETAILS: WE START OFF THE LONG TERM IN SOUTHWEST FLOW
ALOFT AS A NORTHERN STREAM TROUGH APPROACHES FROM THE WEST.
MONDAY WILL BE DRY DURING THE DAY WITH NORMAL TO SLIGHTLY ABOVE
NORMAL HIGHS FOR THIS TIME OF YEAR, MAINLY IN THE LOWER 50S TO
THE LOWER 60S. THAT BEING SAID, WE WILL SEE INCREASING CLOUDS
THROUGH THE DAY WHICH MAY KEEP TEMPERATURES IN CHECK A LITTLE
BIT. THE TROUGH AXIS APPROACHES MONDAY EVENING ALONG WITH COLD
FRONT, INCREASING PRECIPITATION CHANCES (50 TO 80 PERCENT)
THROUGH THE NIGHT. WHILE PRECIPITATION WILL BE WIDESPREAD, THE
BEST CHANCES WILL GENERALLY BE ACROSS THE NORTH. HOWEVER, EVEN
HERE, NBM PROBABILITIES ONLY MAX OUT IN THE 20 TO 40 PERCENT
RANGE FOR GREATER THAN A HALF INCH OF LIQUID PRECIPITATION. SOME
SNOW WILL LIKELY MIX IN OVER THE MOUNTAINS BUT ANY ACCUMULATION
WILL BE LIGHT.
PRECIPITATION CHANCES WILL DIMINISH TUESDAY MORNING AS THE
TROUGH MOVES OUT QUICKLY TO THE EAST BUT A FEW SHOWERS MAY
LINGER THROUGH THE DAY, ESPECIALLY ACROSS THE MOUNTAINS. HIGHS
WILL BE COOLER ON TUESDAY BEHIND THE FRONT, IN THE MID 30S TO
THE UPPER 40S IN THE MOUNTAINS, AND IN THE 50S OVER THE
FOOTHILLS DOWN TO THE COAST. WESTERLY WINDS WILL ALSO BE QUITE
BREEZY BEHIND THE FRONT THROUGH THE AFTERNOON WHEN WE COULD SEE
SOME SUSTAINED VALUES IN THE 20 TO 25 MPH RANGE AND GUSTS TO 35
MPH.
WEDNESDAY CONTINUES TO LOOK MOSTLY DRY DURING THE DAY AS LOW
AMPLITUDE RIDGING MOVES THROUGH THE REGION QUICKLY. HIGHS WILL
BE SIMILAR TO TUESDAY BUT MAYBE JUST A TOUCH WARMER. THE NEXT
TROUGH/FRONT THEN APPROACHES WEDNESDAY NIGHT LEADING TO MORE
PRECIPITATION CHANCES. THERE IS CURRENTLY GOOD AGREEMENT IN THE
GUIDANCE THAT A SHORTWAVE WILL MOVE THROUGH THE REGION, BUT THE
EXACT TRACK OF THE LOW AND HEAVIER PRECIPITATION REMAINS FAIRLY
UNCERTAIN. EITHER WAY, TOTAL AMOUNTS ALSO LOOK FAIRLY LIGHT WITH
THIS SYSTEM WITH ONLY LOW TO MEDIUM PROBABILITIES FOR GREATER
THAN A HALF INCH OF LIQUID. MOST OF THE PRECIPITATION WILL MOVE
OUT BY THURSDAY MORNING, BUT LINGERING SHOWERS WILL REMAIN
POSSIBLE THROUGH THE DAY ON THURSDAY. FINALLY, ANOTHER TROUGH
APPROACHES LATER IN THE DAY ON FRIDAY INTO SATURDAY BUT DETAILS
REGARDING SCOPE AND TIMING REMAIN VERY UNCERTAIN THIS FAR OUT.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
SHORT TERM...BORDERLINE VFR/MVFR CEILINGS LIKELY CONTINUE IN
HIE THROUGH SUNDAY MORNING. VFR CONDITIONS PREVAIL ELSEWHERE
THROUGH TOMORROW NIGHT. WESTERLY WIND GUSTS OF AROUND 25-30KT
STEADILY DIMINISH THIS EVENING.
LONG TERM...VFR CONDITIONS ARE EXPECTED THROUGH THE DAY MONDAY.
A DISTURBANCE WILL THEN CROSS THE REGION MONDAY NIGHT INTO
TUESDAY BRINGING SCATTERED SHOWERS AND LIKELY AT LEAST MVFR
CEILINGS. WE SHOULD SEE A RETURN TO VFR CONDITIONS TUESDAY WITH
AN INCREASE IN WIND GUSTS TO AROUND 30 KNOTS. WEDNESDAY LOOKS
TO REMAIN VFR AT LEAST THROUGH THE DAY WITH LIGHTER GUSTS.
ANOTHER DISTURBANCE MAY APPROACH WEDENSDAY NIGHT WITH SIMILARLY
LOWER CEILINGS AND SHOWERS.
MARINE
SHORT TERM...CONDITIONS FALL TO SCA LEVELS EARLY THIS EVENING,
AND CONTINUE THROUGH DAYBREAK TOMORROW. SEAS CONTINUE TO LOWER
THROUGH THE DAY ON SUNDAY AND SUNDAY NIGHT.

THE DAY ON MONDAY. A DISTURBANCE THEN APPROACHES MONDAY NIGHT,
LEADING TO INCREASING WIND GUSTS AND BUILDING SEAS THROUGH
TUESDAY NIGHT. THERE MAY BE A BREAK IN SCA CONDITIONS WEDNESDAY
THROUGH WEDNESDAY NIGHT, BUT ANOTHER DISTURBANCE CROSSES,
BRINGING SCA WINDS AND SEAS BACK FOR THURSDAY.
