UNDER SURFACE INVERSIONS. TEMPERATURES SHOULD REBOUND QUICKLY AS
THE SURFACE HIGH PRESSURE PUSHES OFF TO THE EAST WITH SOUTHERLY
RETURN FLOW BECOMING ESTABLISHED AHEAD OF AN APPROACHING COLD
FRONT FROM QUEBEC. IN ADDITION, A DEVELOPING LOW PRESSURE SYSTEM
FROM THE CAROLINA COAST WILL BE MOVING OFF TO THE NORTHEAST.
CLOUD COVER WILL BE ON THE INCREASE THROUGHOUT THE DAY BUT
TEMPERATURES SHOULD STILL REBOUND INTO THE UPPER 50S OUTSIDE OF
THE MOUNTAINS. RAIN SHOWER ACTIVITY WILL BE ON THE INCREASE
TOWARDS SUNSET AS SHOWERS FROM THE COASTAL SKIRT COASTAL AREAS
AND SHOWERS FROM THE FRONT APPROACH WESTERN NH.

SHOWERS LIKELY ACROSS THE WHOLE FORECAST AREA. A BRIEF PERIOD OF
MODERATE TO HEAVY RAIN IS POSSIBLE DURING FROPA UNDER SOME
HEAVIER SHOWER ACTIVITY. OVERALL, RAINFALL AMOUNTS WILL BE
WIDESPREAD QUARTER OF AN INCH, BUT CAN'T RULE OUT ISOLATED HIGH
END AMOUNTS UP AROUND 0.5" IN SOME AREAS. FRONT QUICKLY PUSHES
OUT OF THE REGION BY MIDNIGHT. UPSLOPE RAIN AND SNOW SHOWERS
DEVELOP ACROSS THE HIGHER TERRAIN AFTER MIDNIGHT, WITH ENOUGH
MOISTURE TO BRING ACCUMULATING SNOWFALL TO THE HIGHER PEAKS
ABOVE 3000FT. OVERALL, AMOUNTS WILL BE LIGHT. TUESDAY'S WEATHER
STORY WILL BE DOMINATED BY GUSTY NORTHWEST WINDS AS 850MB WINDS
INCREASE TO 50KTS WITH MIXING HEIGHTS UP TO AROUND 4000FT. THIS
WILL SUPPORT WIND GUSTS WELL INTO THE 30 MPH WITH SOME ISOLATED
GUSTS OVER THE LAKES AND LEE-SIDE OF THE MOUNTAINS UP TO 45
MPH. LIMITED POWER OUTAGE THREAT IS POSSIBLE WITH SOME DOWNED
BRANCHES POSSIBLE ONCE AGAIN. WINDS BEGIN TO SUBSIDE BY THE
SUNSET AS DEEP MIXING IS LOST AND PRESSURE GRADIENT BEGINS TO
SLACKEN A BIT.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
KEY MESSAGES:
* AN ACTIVE BUT RELATIVELY LOW IMPACT PATTERN CONTINUES THROUGH
THE LONG TERM WITH VARIOUS CHANCES OF PRECIPITATION TO INCLUDE
THE FIRST NORTH COUNTRY VALLEY SNOW EARLY THURSDAY MORNING.
* GUSTY WINDS ARE LIKELY ON THURSDAY AND SATURDAY WITH GALES
POSSIBLE OVER THE COASTAL WATERS.

NEAR SEASONAL HIGH TEMPERATURES AND NO SIGNIFICANT WEATHER

WEDNESDAY NIGHT THROUGH THURSDAY, NEXT SHORTWAVE TROUGH ALBERTA
CLIPPER QUICKLY APPROACHES NEW ENGLAND. THE LOW PRESSURE SYSTEM
IS EXPECTED TO STRENGTHEN IN THE GULF OF MAINE AS IT PULLS OFF
TO THE EAST INTO CANADA. SOME SPREAD EXISTS IN THE NORTH/SOUTH
TRACK WHICH WILL CONTROL THE RAIN/SNOW ELEVATION. ENSEMBLE MEAN
DOES SHOW THE POTENTIAL FOR SOME VALLEY SNOW ACROSS NORTHERN NH
