SYNOPSIS
STACKED LOW PRESSURE MOVES TOWARDS NORTHERN MAINE TODAY,
BRINGING A WIND SHIFT AND A END TO RAIN ACROSS MUCH OF THE AREA.
UPSLOPE RAIN SHOWERS CONTINUE IN THE MOUNTAINS, AS WINDS BECOME
SOUTHWEST AND THEN WEST SATURDAY WITH BREEZY CONDITIONS. HIGH
PRESSURE BUILDS IN FOR 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 /THROUGH TODAY/
OCCLUDED LOW PRESSURE WILL SLOWLY DRIFT INTO NORTHERN ME TODAY.
THE TRACK SUPPORTS A BRIEF LULL IN GUSTY WINDS THAT OCCURRED
OVERNIGHT BEFORE INCREASING ONCE AGAIN OUT OF THE WEST LATER
THIS MORNING AND AFTERNOON. MOMENTUM TRANSFER DUE TO LOW LEVEL
INSTABILITY AND ARRIVING COLD AIR ALOFT WILL TAP INTO A VERY
EXPANSIVE AND GROWING WIND FIELD AS MID TO UPPER LOWS STACK NEAR
NORTHERN ME THIS EVENING. GUSTS SHOULD PEAK MID TO LATE
AFTERNOON, GENERALLY 30 TO 40 MPH.
THE BULK OF RAIN LIFTS NORTH OF THE FORECAST AREA QUICKLY THIS
MORNING, WITH JUST A FEW SHOWERS TRAILING THROUGH NH AND
INTERIOR ME. AS WINDS BECOME WSW THROUGH THE DAY, DO EXPECT
UPSLOPE SHOWERS TO TAKE HOLD IN THE MOUNTAINS, KEEPING RAIN IN
THE FORECAST FOR POINTS NORTH OF AND ALONG THE RIDGES. THE
ARRIVAL OF COOLER AIR WILL MEAN A MORE DEFINITIVE SWITCH TO
WINTER CONDITIONS AT THE HIGHER PEAKS OF THE WHITES BY THIS
EVENING, AND THEN SUMMITS BELOW INTO THE REMAINDER OF THE
WEEKEND.
SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/
UPSLOPE SHOWERS CONTINUE TONIGHT FOR THE MOUNTAINS, WITH SOME
MOISTURE SPILLING INTO THE FOOTHILLS AND INTERIOR OVERNIGHT.

PRECIP OUTSIDE OF THE MOUNTAINS. PEAKS IN THE WHITES MAY SEE A
COUPLE INCHES OF SNOW BY THE TIME SUNDAY COMES AROUND, ALONG
WITH WIND CHILLS AT OR BELOW 0.
IT REMAINS BREEZY FOR THE LOWLANDS AS WELL TONIGHT AND SATURDAY.
OVERNIGHT GUSTS WILL BE LESS FREQUENT THAN DAYTIME, BUT 20 TO 30
MPH GUSTS SHOULD CONTINUE THROUGH THE NIGHT. WILL SEE THESE PICK
UP ONCE AGAIN DURING THE DAYTIME SATURDAY FOR MOST OF THE
FORECAST AREA. GUSTS WILL AGAIN REACH 30 TO 40 MPH FOR MOST
LOCATIONS.
OVERCAST SKIES CONTINUE FOR THE MOUNTAINS SATURDAY, BUT MORE SUN
SHOULD SHOW FOR POINTS TOWARDS THE COAST AND INTERIOR. DESPITE
THIS, THE STEADY CAA WILL BE FELT. HIGHS TOP OUT IN THE 40S TO
LOWER 50S FOR THE DAY.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
KEY MESSAGES:
*GUSTY WINDS SUBSIDE SATURDAY NIGHT WITH COOLER TEMPERATURES
RETURNING.
*SEASONABLY COOL TEMPERATURES LOOK TO PREVAIL THROUGH MUCH OF NEXT
WEEK WITH BOUTS OF UNSETTLED WEATHER AS A SERIES OF SYSTEMS MOVE
ACROSS OR NEAR NEW ENGLAND.
DETAILS:
LOW PRESSURE WILL CONTINUE TO EXIT WELL TO OUR NORTHEAST ON
SATURDAY NIGHT AS THE H5 PATTERN BEGINS TO FLATTEN. THIS WILL
YIELD TO A DRY NIGHT WITH LOW TEMPERATURES PRIMARILY FALLING
INTO THE 20S UNDER PARTLY CLOUDY SKIES. SURFACE HIGH PRESSURE
WILL MOVE ACROSS NEW ENGLAND ON SUNDAY, ALLOWING FOR PARTLY
CLOUDY SKIES, LIGHTER WESTERLY WINDS, AND HIGH TEMPERATURES INTO
THE 40S TO LOWER 50S FROM NORTH TO SOUTH.
A WEAK TROF OF LOW PRESSURE MAY THEN CROSS ON MONDAY INTO
MONDAY NIGHT, WHICH MAY RESULT IN SCATTERED SHOWERS WITH SNOW
ACROSS THE HIGHER TERRAIN. HIGHS WILL GENERALLY BE INTO THE 50S
WITH LOWS INTO THE 30S. MID-LVL RIDGING THEN LOOKS TO RETURN FOR
THE MIDDLE OF THE WEEK BEFORE ANOTHER POTENTIAL DISTURBANCE
ARRIVES BY THE END OF THE WEEK. TEMPERATURES WILL REMAIN NEAR TO
SLIGHTLY BELOW AVG.
