AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 323 PM EDT FRI AUG 24 2007 .SYNOPSIS... HOT HUMID WEATHER WILL BE WITH US FOR THE FIRST HALF OF THE WEEKEND...AS A SOUTHWEST FLOW PERSISTS. OUTSIDE OF ISOLATED THUNDERSTORMS...MOST OF THE TIME THROUGH LATE SATURDAY WILL BE RAIN-FREE. FROM LATE SATURDAY AFTERNOON INTO EARLY SUNDAY...A COLD FRONT IS EXPECTED TO CROSS THE AREA...WITH MORE WIDESPREAD THUNDERSTORMS ANTICIPATED. ON SUNDAY...IMPROVING WEATHER IS EXPECTED...AS A DRIER AIR MASS COMES IN FROM THE NORTHWEST. && .NEAR TERM /THROUGH TONIGHT/... CONVECTION HAS HAD A TOUGH TIME DEVELOPING SO FAR...AS THE AIR REMAINS FAIRLY CAPPED (CIN VALUES OF MORE THAN 100 J/KG ON THIS AFTERNOONS SOUNDINGS AT BUFFALO AND ALBANY). OTHER THAN THE PASSAGE OF A WEAK SHORT-WAVE THIS EVENING...AND FIXED FORCING FROM TERRAIN AND ANY LAKE BOUNDARIES...THUNDERSTORMS SHOULD BE WIDELY SCATTERED THROUGH THE EVENING HOURS. LATER TONIGHT...WE COULD SEE AN ISOLATED SHOWER OR THUNDERSTORM OVER OUR NORTHERN AND WESTERN ZONES...BUT FOR THE MOST PART RAIN- FREE CONDITIONS ARE EXPECTED.

SATURDAY SHOULD BE A HOT HUMID DAY...WITH A DEEP SOUTHWESTERLY FLOW OUT AHEAD OF AN APPROACHING COLD FRONT. IT APPEARS THAT THE FRONT WILL NOT GET CLOSE ENOUGH TO TRIGGER MUCH IN THE WAY OF CONVECTION UNTIL LATER IN THE AFTERNOON FOR MOST OF THE REGION. IN FACT...NORTHEAST PA SHOULD STAY RAIN-FREE FOR THE BALANCE OF THE DAY. WHATEVER STORMS DO FORM HAVE SOME SEVERE POTENTIAL...AS THE WIND FIELDS WILL BE INCREASING THROUGH THE AFTERNOON. IT LOOKS LIKE THE BEST CHANCE FOR SHOWERS AND STORMS WILL BE SATURDAY NIGHT...AS THE FRONT ITSELF LUMBERS ACROSS NY AND PA. PWAT VALUES INCREASE TO NEAR 2 INCHES TOMORROW EVENING...SO SOME HEAVY RAINERS ARE EXPECTED. IT LOOKS LIKE THERE MAY BE ENOUGH FLOW TO KEEP THE STORMS PROGRESSIVE IN NATURE. ON SUNDAY...DRIER AIR SHOULD FILTER INTO THE FORECAST AREA...AS THE AFORMENTIONED FRONT PUSHES SOUTHEAST OF THE REGION. WE KEPT IN A CHANCE OF LINGERING SHOWERS IN THE MORNING...ESPECIALLY OVER NORTHEAST PA AND THE CATSKILLS. HIGHS SHOULD BE ABOUT 10 DEGREES LOWER ON SUNDAY THAN THEYLL BE SATURDAY. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... FRONT STALLS OUT SOUTH OF THE FA SUNDAY NIGHT WITH HIGH PRESSURE BUILDING IN BEHIND. GFS IS SLIGHTLY FASTER WITH FRONT AND HAVE FOLLOWED HPC/S SLOWER PROGRESSION...MORE IN LINE WITH ECMWF.
