SYNOPSIS...  AS HIGH PRESSURE MOVES EAST INTO THE ATLANTIC TODAY, WE WILL SEE A WARM, MOIST SOUTHWEST FLOW OVER THE AREA. EXPECT WARMER TEMPERATURES AND PLENTY OF CLOUD COVER TODAY. A COLD FRONT WILL SLIDE IN FROM THE NORTHWEST THIS EVENING AND MAY SPARK A FEW RAIN OR SNOW SHOWERS AS IT CROSSES THE REGION TONIGHT. WITH CLOUDS DEPARTING ON SATURDAY MOST OF THE AREA WILL WARM INTO THE 40S BEFORE DROPPING BACK INTO THE 20S SATURDAY NIGHT. THE NEXT LOW PRESSURE SYSTEM TRACKS OUT OF THE SOUTHEAST US AND SLIDES OFFSHORE SOUTH OF NEW ENGLAND SUNDAY INTO SUNDAY NIGHT. THIS COULD BRING SOME LIGHT SNOW OR RAIN AS IT PASSES BY TO OUR SOUTH. A STRONGER COLD FRONT BLOWS THROUGH ON MONDAY WITH A STIFF NORTHWEST WIND USHERING IN COLDER AIR WHICH LASTS THROUGH MIDWEEK.

&&


.NEAR TERM /TODAY/... SOUTHWEST FLOW HAS ALREADY BEGUN THIS MORNING WITH AN INCREASINGLY WARM/MOIST LOW LEVEL ENVIRONMENT MOVING IN. THIS IS EVIDENCED BY EARLY MORNING SATELLITE IMAGERY WHICH SHOWED LOW CLOUDS SPREADING ACROSS THE REGION, PUNCTURED IN SPOTS BY THE HIGHEST PEAKS. THIS CLOUD COVER WILL BE IN AND OUT THROUGH THE DAY BUT PROBABLY THICKER UP NORTH. THE TEMPERATURE WARMS INTO THE LOW TO MID 30S FOR MOST AREAS, PERHAPS EVEN NEAR 40 IN MORE SUNNY SPOTS.

&&


SHORT TERM /TONIGHT AND SATURDAY/...     A TROUGH PASSING THROUGH THE NORTHERN STREAM SCRAPES THE CAP OF MAINE AND SENDS A FRONT THROUGH NORTHERN NEW ENGLAND TONIGHT. WITH THE LOW LEVEL MOISTURE AHEAD OF IT, WE COULD SQUEEZE OUT SOME LIGHT RAIN OR SNOW SHOWERS AS IT MOVES THROUGH, ESPECIALLY IN NORTHERN PARTS OF THE AREA. WITH CLOUDS AND DECENT MIXING DON'T EXPECT THE TEMPERATURE TO FALL THAT MUCH TONIGHT. IN FACT, ALTHOUGH WE WILL BE BEHIND THE COLD FRONT BY SATURDAY MORNING, THE NORTHWEST FLOW IN ITS WAKE WILL PROMOTE DEEPER MIXING AND WARM THINGS UP WELL INTO THE 40S BEFORE THE COLDER AIR IS FELT SATURDAY NIGHT.

&&


LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...     THE CUTOFF LOW PRESSURE SYSTEM OVER THE SOUTHERN PORTIONS OF THE UNITED STATES WILL ONCE AGAIN DOMINATE WEATHER CONDITIONS TO OUR SOUTH FOR THE BEGINNING PORTIONS OF THE EXTENDED FORECAST. A SERIES OF SURFACE LOWS WILL BE TRIGGERED ALONG AND NEAR THE MID ATLANTIC REGION SUNDAY IN RESPONSE TO THE UPPER LOW REACHING THE EASTERN SEABOARD.

THIS SYSTEM WILL GRADUALLY INTENSIFY SUNDAY NIGHT AS THE SURFACE RIDGE PULLS EAST, INTO THE CANADIAN MARITIMES. COOL, DRY AIR WILL REMAIN IN PLACE NEAR GROUND LEVEL ACROSS INTERIOR LOCATIONS. MEANWHILE, TEMPERATURES AT H8 WILL REMAIN NEAR OR SLIGHTLY ABOVE 0C. THERE SHOULD BE SUFFICIENT EVAPORATIONAL COOLING TO ALLOW FOR MAINLY SNOW AWAY FROM THE COAST WITH PERHAPS SOME RAIN ALONG AND NEAR THE COASTAL FRONT.

IN TERMS OF TRACK AND DEVELOPMENT, MOST MODELS WITHIN THE 00Z RUN KEEP THE BULK OF THE PRECIPITATION TO OUR SOUTH AND EAST AS THE SYSTEM BECOMES ORGANIZED, BUT SLIPS OUT TO SEA. THE OUTLIER IS THE EURO SOLUTION WHICH BRINGS SURFACE DEVELOPMENT CLOSER TO THE COAST WITH ABOUT A HALF INCH LIQUID EQUIVALENT PRECIPITATION TO SOUTHERNMOST AREAS. HAVE USED A BLEND OF MODELS FOR OUR QPF, BRINGING AN INCH OR TWO SNOWFALL OVER FAR SOUTHERNMOST NEW HAMPSHIRE THROUGH MONDAY.

THEREAFTER, A GUSTY NORTHWEST FLOW STRENGTHENS BEHIND THE DEPARTING SYSTEM. THIS WILL ALLOW FOR SEVERAL DAYS OF UPSLOPE CLOUDS IN THE NORTHERN MOUNTAINS AND POSSIBLY SCATTERED SNOW SHOWERS INTO THE MIDDLE OF NEXT WEEK. A WARMING TREND ON A DEEP MERIDIONAL FLOW DEVELOPS LATE IN THE WEEK.

&&


.AVIATION /08Z FRIDAY THROUGH TUESDAY/... SHORT TERM...  MVFR CLOUD DECK EXPECTED TO BE IN AND OUT THROUGH THE DAY, MORE IN THAN OUT UP NORTH AND MORE OUT THAN IN DOWN SOUTH. A COLD FRONT MOVES THROUGH TONIGHT WITH A CHANCE OF SOME LIGHT SNOW MAINLY UP NORTH WITH WINDS SHIFTING TO THE NORTHWEST THROUGH THE NIGHT. BY SATURDAY IT SHOULD BE VFR FOR MOST AREAS WITH A NORTHWEST BREEZE, THOUGH THE MOUNTAINS COULD HANG ON TO SOME MVFR CEILINGS THROUGH THE DAY.

LONG TERM...  VFR CONDITIONS EXPECTED SATURDAY NIGHT. LOWERING CEILINGS WITH WITH POCKETS OF MVFR CONDITIONS POSSIBLE IN LIGHT SNOW OR RAIN AND SNOW MIX SUNDAY NIGHT THROUGH MONDAY. GUSTY NW WINDS ARE EXPECTED TO FOLLOW BEGINNING ON TUESDAY.

MARINE...  
   SHORT TERM...  SOUTHWEST FLOW INCREASES AROUND THE BACK SIDE OF HIGH PRESSURE EXITING TO THE EAST AND AHEAD OF A COLD FRONT APPROACHING FROM THE NORTHWEST. A SMALL CRAFT ADVISORY HAS BEEN ISSUED FOR THE OUTER WATERS AS WINDS COULD GUST TO 30KT MAINLY TONIGHT WITH WAVE HEIGHTS BUILDING ESPECIALLY IN THE CENTRAL AND EASTERN GULF OF MAINE. COULD SEE SCA CALIBER WINDS INSIDE THE ISLANDS OF PENOBSCOT BAY TONIGHT, BUT NOT CONFIDENT ENOUGH TO ISSUE AN ADVISORY THERE YET AS WIND FORECASTS ARE OFTEN OVERDONE ON A SOUTHWEST FLOW. COLD FRONT PUSHES IN FROM THE NORTHWEST EARLY SATURDAY MORNING ENDING THE ADVISORY LEVEL WINDS AND SHIFTING THEM TO THE NORTHWEST AND THEN NORTH THROUGH THE DAY SATURDAY.

LONG TERM...  SCA CONDITIONS LIKELY WITH GALES POSSIBLE ON THE OCEAN WATERS MONDAY NIGHT AND TUESDAY, WITH SCA CONDITIONS IN THE BAYS.
