SYNOPSIS...  LOW PRESSURE WILL TRACK SOUTH OF CAPE COD LATER TONIGHT INTO EARLY MONDAY AND WILL BRING LIGHT SNOW TO SOUTHERN AREAS. HIGH PRESSURE DOMINATES THE WEATHER FOR TUESDAY AND WEDNESDAY. THE NEXT CHANCE OF PRECIPITATION OCCURS WEDNESDAY NIGHT INTO THURSDAY AS LOW PRESSURE APPROACHES FROM THE SOUTH AND WEST. MORE CANADIAN HIGH PRESSURE BUILDS INTO THE REGION FRIDAY AND SATURDAY. LOW PRESSURE MOVES UP TO THE NEW ENGLAND COASTLINE NEXT SUNDAY.

&&


.NEAR TERM /THROUGH TONIGHT/... A BEAUTIFUL DAY ACROSS NEW ENGLAND AS HIGH PRESSURE CRESTS OVER THE REGION. A FEW HIGH CIRRUS CLOUDS ARE JUST STARTING TO MOVE INTO VERMONT ON THE LEADING EDGE OF THE UPPER LEVEL DYNAMICS OF OUR NEXT SYSTEM. THE MAINLY CLEAR SKIES SHOULD CONTINUE THROUGH THE FIRST PART OF THE EVENING, BEFORE THE APPROACHING LOW PUSHES MORE CLOUDS INT THE REGION AFTER MIDNIGHT. LOWS WILL DROP TO THE SINGLE DIGITS NORTH WITH TEENS SOUTH.

&&


SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...     A ELONGATED AREA OF LOW PRESSURE STRETCHING ACROSS THE SOUTHERN APPALACHIANS WILL MOVE NORTHEASTWARDS CROSSING THE MID ATLANTIC AND SOUTHERN NEW ENGLAND ON MONDAY. ALL GUIDANCE CONTINUES TO PUT THE CORE OF THIS SYSTEM TO OUR SOUTH MOVING SOUTH OF LONG ISLAND AND EAST ACROSS THE BENCHMARK PUTTING SOUTHERN NEW HAMPSHIRE ON THE NORTHERN PERIPHERY OF THE PRECIPITATION. EXPECT LIGHT SNOW TO BREAK OUT ACROSS THE REGION EARLY MONDAY MORNING RESULTING IN A FEW INCHES OF ACCUMULATION ALONG THE MASSACHUSETTS BORDER THROUGH THE END OF THE DAY. DYNAMICS FOR THIS SYSTEM LIE MOSTLY SOUTH WITH FAIRLY MODEST UPWARD MOTION ASSOCIATED WITH THE WAA AT PRECIPITATION ONSET BEING THE BEST CHANCE FOR HIGHER PRECIPITATION RATES, ALTHOUGH LIMITED SNOW TOTALS ARE EXPECTED. SNOW SHOWERS WILL COME TO AN END MONDAY NIGHT AS THE SYSTEM PASSES TO OUR EAST OVER THE WATERS.

&&


LONG TERM /TUESDAY THROUGH SUNDAY/...     HIGH PRESSURE OVER THE GREAT LAKES WILL CONTINUE TO BUILD EASTWARD ON TUESDAY. THIS WILL ALLOW FOR CHILLY TEMPERATURES IN THE TEENS NORTH TO 20S IN THE SOUTH FOR DAYTIME HIGHS. WINDS WILL CONTINUE TO BE GUSTY FROM THE NORTHWEST AS WELL.

THE RIDGE WILL CREST OVER OUR FORECAST AREA ON WEDNESDAY. 12Z MODEL SUITE IN RELATIVELY GOOD AGREEMENT WITH THE FORECAST DETAILS WITH A WEAK AREA OF LOW PRESSURE FORMING ALONG THE MID ATLANTIC COASTLINE WEDNESDAY NIGHT. THE SYSTEM WILL LIKELY TRACK NEAR THE CAPE COLD CANAL THURSDAY MORNING. THE SYSTEM WILL BE A FAST MOVER, HOWEVER SEVERAL INCHES OF SNOW CAN BE EXPECTED IN NEW HAMPSHIRE AND MAINE WITHIN A BRIEF PERIOD OF STRONG WARM AIR ADVECTION.

THE PRECIPITATION MAY END AS A BRIEF PERIOD OF LIGHT RAIN OR SLEET AS IT WINDS DOWN THURSDAY, HOWEVER THIS WILL MAINLY BE A SNOW EVENT.

MORE HIGH PRESSURE WILL BUILD INTO THE REGION FRIDAY AND SATURDAY. MIXED PRECIPITATION IS THEN EXPECTED LATE IN THE WEEKEND. LOW PRESSURE WILL CROSS OVER THE EASTERN GREAT LAKES AS A SECONDARY AREA OF LOW PRESSURE DEVELOPS ALONG THE SOUTHERN NEW ENGLAND COASTLINE.

&&


.AVIATION /19Z SUNDAY THROUGH FRIDAY/... SHORT TERM...   VFR CONDITIONS ACROSS THE REGION AS HIGH PRESSURE SLOWLY MOVES EASTWARDS. BY EARLY MORNING MOST SITES WILL TRANSITION TO MVFR AS CLOUDS LOWER AHEAD OF THE LOW PASSING TO OUR SOUTH. MONDAY MORNING LOOK FOR MAINLY MVFR IN SHSN FOR SOUTHERN NEW HAMPSHIRE AND INTO SOUTHWEST MAINE, HOWEVER A BRIEF PERIOD OF IFR IS POSSIBLE IN THE LATE MORNING. THE SYSTEM WILL THEN EXIT TO THE EAST RETURNING US TO VFR BY LATE MONDAY NIGHT.

LONG TERM...  AREAS OF IFR CONDITIONS DEVELOPING IN LOWERING CEILINGS AND SNOW WEDNESDAY NIGHT INTO THURSDAY.
