AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
320 PM EDT TUE JUL 22 2003

UPPER LEVEL TROUGH OVER THE ERN U.S CONTINUES TO AMPLIFY...WITH
NUMEROUS SHORTWAVES IN THE FLOW GENERATING SHOWERS AND
THUNDERSTORMS. ONE BATCH IS MOVING THROUGH ERN ZONES...BUT IS
WEAKENING. ANOTHER WEAK SHORTWAVE IS PRODUCING TSTORMS OVER STEUBEN
COUNTY...WHILE A STRONGER SHORTWAVE OVER OHIO IS GENERATING AN AREA
OF TSTORMS OVER NW PA AND SW NY. 24-HOUR RAINFALL REPORTS ENDING
THIS MORNING WERE IN THE 1-3 RANGE OVER A LARGE PORTION OF OUR
AREA...WITH A COUPLE REPORTS EXCEEDING 3 INCHES. THE CENTRAL
SOUTHERN TIER AND SUSQUEHANNA REGIONS OF NY AND THE WYOMING VALLEY
IN NE PA WERE HARDEST HIT.

THE AFOREMENTIONED SHORTWAVES WILL PRODUCE TSTORMS THIS EVENING...
WITH ADDITIONAL SHORTWAVE ENERGY OVER THE OHIO VALLEY KEEPING THE
ACTIVITY GOING OVERNIGHT AND INTO WEDNESDAY. HEAVY RAIN SHOULD BE THE
BIGGEST PROBLEM TONIGHT...SINCE LOW/MID-LEVEL WINDS ARE FAIRLY WEAK
AND PWS ARE AROUND 1.5. WILL KEEP FLASH FLOOD WATCH GOING TONIGHT
FOR ALL ZONES. WILL GO WITH CAT POPS OVER CENTRAL/SE ZONES AND
LIKELY POPS OVER NW ZONES...AND MENTION THE POSSIBILITY OF HEAVY
RAIN IN ALL ZONES.

WEDNESDAY..A WAVE OF LOW PRESSURE WILL MOVE NORTH THRU ERN NY AS
ADDITIONAL SHORTWAVE ENERGY MOVES THROUGH THE TROUGH. THIS SHOULD
KEEP OUR AREA WET...ESPECIALLY CENTRAL/ERN ZONES...WITH MORE HEAVY
RAIN POSSIBLE.

WED NIGHT..IN THE WAKE OF THE LOW PRESSURE WAVE THE SHOWER ACTIVITY
WILL DECREASE IN COVERAGE AND INTENSITY. THE PASSAGE OF THE LOW
PRESSURE AREA SHOULD HELP A WEAK COLD FRONT MOVE THROUGH THE AREA...
BUT THE AIRMASS BEHIND THIS FRONT WONT BE MUCH DIFFERENT THAN WHAT
WERE IN NOW.

THU..WE REMAIN IN THE RRQ OF THE UPPER LEVEL JET...SO THERE WILL BE
A CONTINUED THREAT OF SHOWERS AND TSTORMS...MAINLY IN THE AFTERNOON.

EXTENDED (THU NIGHT-TUE)..THE TROUGH CURRENTLY OVER THE ERN U.S.
LIFTS OUT SLOWLY WHILE A NEW ONE DIGS IN FOR THE WEEKEND. OTHER
THAN FRIDAY THERE WILL BE A CHANCE OF RAIN THROUGHOUT THE EXTENDED
PERIOD. TEMPS WILL REMAIN NEAR SEASONAL NORMS.

WORK ZONES OUT. ZONES BY 330 PM.

.BGM...FLASH FLOOD WATCH THROUGH TONIGHT FOR ALL ZONES.
