AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW YORK NY ISSUED BY NATIONAL WEATHER SERVICE TAUNTON MA 343 PM EDT THU APR 22 2010 .SYNOPSIS... COLD FRONT WILL MOVE ACROSS THE REGION THIS EVENING AND WILL BE FOLLOWED BY CLEARING SKIES AND DRIER WEATHER FOR THE OVERNIGHT HOURS THROUGH SATURDAY. A STORM SYSTEM APPROACHES FROM THE WEST SATURDAY NIGHT AND IMPACTS THE LOCAL AREA WITH SOME RAINFALL SUNDAY INTO EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... COLD FRONT GRADUALLY MOVES ACROSS THE CWA EARLY THIS EVENING. HOWEVER...BEFORE THEN...A FEW WAVES OF SHOWERS ALONG WITH EMBEDDED THUNDERSTORMS WILL OCCUR. GIVEN LOW FREEZING LEVELS AND STEEP LOW LEVEL LAPSE RATES...SOME OF THE STRONGER CELLS COULD PRODUCE SMALL HAIL AND BRIEF WIND GUSTS UP TO 45 MPH THROUGH ABOUT 6 PM OR SO BEFORE THE ACTIVITY MOVES OFF TO THE EAST. THE ACTIVITY MAY LAST AN HOUR OR TWO LONGER ACROSS CT. OTHERWISE...WE EXPECT CLEARING SKIES DURING THE EVENING AND OVERNIGHT HOURS IN THE WAKE OF THE COLD FRONT. TEMPERATURES SHOULD GET DOWN INTO THE UPPER 30S IN THE OUTLYING AREAS OF THE NORTH AND WEST...BUT WE THINK THE WINDS WILL STAY UP JUST ENOUGH TO PRECLUDE ANYTHING MORE THAN PATCHY FROST. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... HIGH PRESSURE GRADUALLY BUILDS IN FROM THE WEST FRIDAY AND FRIDAY NIGHT. THIS WILL RESULT IN FAIR WEATHER. THE ONLY REAL CONCERN DURING THE PERIOD IS THE POTENTIAL FOR FROST FRIDAY NIGHT.

MAIN FEATURE FOR LONG TERM IS STRONG UPPER LOW CURRENTLY IN THE WESTERN U.S. THIS FEATURE WILL TRACK ACROSS THE COUNTRY OVER THE COURSE OF THE NEXT SEVERAL DAYS. HIGH PRESSURE SLIDES OFF THE MID ATLANTIC COASTLINE SATURDAY...WHILE SOUTHERN STREAM ENERGY IS WRAPPED INTO VERTICALLY STACKED LOW...WHICH AT THAT POINT SHOULD BE IN THE CENTRAL U.S. MEANWHILE WARM FRONT ASSOCIATED WITH THIS SYSTEM SHOULD POSITION ITSELF NEAR THE DELMARVA AREA ON SATURDAY...WITH INCREASING MOISTURE OVER THE CWA. MOST MODELS INDICATE PRECIP HOLDING OFF ON SATURDAY. PLAN TO GO WITH SOME INCREASE IN CLOUDS BUT DRY...EXCEPT A SLIGHT CHANCE POP SW PORTION OF THE CWA. BETTER CHANCE FOR RAIN SATURDAY NIGHT AND SUNDAY AS SOUTHWEST FLOW ALOFT BRINGS GULF MOISTURE INTO THE MID ATLANTIC REGION. VERTICALLY STACKED LOW LINGERS OVER THE MIDWEST...BUT MODELS INDICATING A WEAKER SECONDARY SURFACE LOW FORMING AND TRACKING OFF THE COASTLINE SATURDAY NIGHT INTO SUNDAY. RAIN BECOMING LIKELY DURING THIS TIMEFRAME. BEHAVIOR OF UPPER LEVEL SYSTEM BECOMES MORE UNCERTAIN FOR THE BEGINNING OF THE WEEK...BUT 12Z GFS AND 00Z ECMWF DO LOOK SIMILAR. THEY GENERALLY INDICATE UPPER LOW WEAKENING AS IT TRACKS FROM OHIO VALLEY INTO THE MID ATLANTIC REGION...WITH A SURFACE LOW TRANSITIONING TO THE COAST. GENERALLY UNSETTLED WEATHER FOR MONDAY...BUT POTENTIAL FOR IMPROVING CONDITIONS TUESDAY. WILL CONTINUE CHANCE POPS FOR THIS PERIOD. SHOULD BE UNDER W/NW FLOW ALOFT FOR MIDWEEK...GOING DRY FOR WED. TEMPERATURES THROUGH THE FORECAST A BLEND OF GMOS AND PREVIOUS. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/...
