AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
1242 AM EST WED DEC 31 2025
SYNOPSIS
BREEZY CONDITIONS CONTINUE TODAY BUT IT WILL BE LESS GUSTY AND
TEMPERATURES WILL BE WARMER. A CLIPPER SYSTEM AFFECTS THE REGION
TONIGHT WITH LIGHT SNOW THAT WILL LAST INTO THURSDAY MORNING.
MAINLY DRY AND COLD WEATHER EXPECTED THROUGH THE WEEKEND INTO
EARLY NEXT WEEK.
NEAR TERM /THROUGH TODAY/
VARIABLY CLOUDY AND LESS WINDY CONDITIONS ARE EXPECTED TODAY.
SFC WINDS GO SOUTHWEST WHICH SHOULD ALLOW FOR TEMPERATURES TO
WARM SOME, WITH HIGHS IN THE MID TO UPPER 20S AT LOWER
ELEVATIONS BUT STILL IN THE TEENS AND LOWER 20S IN OUR MOUNTAIN
ZONES.
SHORT TERM /TONIGHT THROUGH THURSDAY/
A STRONG AND AMPLIFYING SHORT WAVE TROUGH DIVING TOWARD OUR
AREA FROM THE GREAT LAKES THIS EVENING WILL AID IN INDUCING
CYCLOGENESIS OVER SOUTHERN NEW ENGLAND WHICH WHEN THEN MOVE
NORTHEASTWARD THU. THIS PROCESS WILL SPREAD MAINLY LIGHT SNOW
ACROSS OUR FORECAST AREA TONIGHT, FIRST ACROSS WESTERN ZONES
THIS EVENING, THEN TO THE COASTAL PLAIN AROUND OR AFTER MIDNIGHT
AS A COASTAL FRONT DEVELOPS. MOISTURE AVAILABILITY WILL THIS
SYSTEM IS QUITE LIMITED AND THIS WILL KEEP SNOWFALL AMOUNTS ON
THE LIGHT SIDE, GENERALLY 1 TO 3 INCHES. HOWEVER WE WILL HAVE TO
WATCH FOR SOME ENHANCEMENT ON THE COAST, ESPECIALLY THE MIDCOAST
AS THE CYCLONE UNDERGOES INTENSIFICATION AND THE COASTAL FRONT
STRENGTHENS. SOME GUIDANCE SOURCES SHOW THE POTENTIAL FOR A
NORLUN-LIKE FEATURE AFFECTING THE MIDCOAST BEFORE MOVING OFF TO
THE NORTHEAST. IF THIS WOULD TO OCCUR THEN IT'S POSSIBLE THAT
ADVISORY LEVEL SNOWFALL AMOUNTS COULD BE REACHED. WILL CONTINUE
TO MONITOR THAT POSSIBILITY.
LIGHT SNOWS CONTINUE, MAINLY IN ME, THROUGH MUCH OF THURSDAY
MORNING BEFORE MOVING OUT TO THE EAST. WINDS PICK UP DURING THE
AFTERNOON HOURS AS THE STRENGTHENING CYCLONE MOVES AWAY.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
QUIET WEATHER SETTLES IN FOR FRIDAY AND THE WEEKEND. IT WILL BE
COOL, WITH TEMPERATURES RUNNING BELOW NORMAL AND DAILY NW
BREEZE THAT KEEPS WIND CHILL VALUES BETWEEN -10 AND 10.
THE NEXT CHANCE FOR WIDESPREAD PRECIP COULD ARRIVE EARLY TO
MID-WEEK NEXT WEEK IN THE FORM OF A ROBUST CLIPPER, BUT THERE
REMAINS A LOT OF SOLUTIONS IN GUIDANCE. THIS IS MAINLY IN
PLACEMENT OF MOISTURE BETWEEN HIGH PRESSURE IN THE CENTRAL CONUS
AND NORTH FLOW ACROSS SOUTHERN CANADA.
VERY LITTLE CHANGE TO THE FORECAST BASED ON THE NEW NBM.
AVIATION /02Z WEDNESDAY THROUGH SUNDAY/
SHORT TERM...VISIBILITY AND SKY CONDITIONS REMAIN VFR THROUGH
TODAY. THE NEXT CHANCE FOR FLIGHT RESTRICTIONS COMES TONIGHT AS
WIDESPREAD LIGHT SNOW WILL LIKELY BRING ABOUT MVFR OR LOWER
VISIBILITIES AND CIGS DOWN TO 500-1000 FT ON THE COASTAL PLAIN
LATE TONIGHT. IMPROVEMENT IS FORESEEN AS THURSDAY MORNING
PROGRESSES.
LONG TERM...VFR IS EXPECTED BY SUNSET FOR MOST TERMINALS THU,
WITH SOME LIGHT SN CONTINUING FOR HIE AND US/CAN BORDER
TERMINALS. GUSTY NW WINDS THURSDAY AFTERNOON 20 TO 25 KTS, SOME
TO 30 KT. HIGH PRESSURE BRINGS MOSTLY VFR CONDITIONS FOR THE
WEEKEND, BUT MVFR CEILINGS MAY BE INTERMITTENT FOR HIE.

LIKELY GOING TO HAVE TO REMAIN UP THROUGH AT LEAST THE FIRST
PART OF WEDNESDAY NIGHT AS WAVE HEIGHTS TAKE A LITTLE BIT LONGER
TO FALL BELOW 5FT. LIGHT FREEZING SPRAY WILL ALSO CONTINUE INTO
THIS MORNING, WITH MORE MODERATE FREEZING SPRAY LIKELY IN THE
SLIGHTLY COLDER WATERS OF PENOBSCOT BAY. SCA LIKELY NEEDED
THURSDAY AS WINDS REMAIN DUE TO STRENGTHENING LOW PRES IN THE
GULF OF MAINE. SOME GALE FORCE WINDS WILL BE POSSIBLE IN THE
NORTHERN COASTAL ZONES IN PROXIMITY TO THE LOW. WAVE HEIGHTS MAY
