AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
330 PM EDT FRI JUL 23 2004
.SHORT TERM (TONIGHT THRU SUNDAY)...
TODAY...COLD FRONT CONTINUES TO MOVE EAST LATE THIS AFTERNOON...
CURRENTLY STRETCHING FROM NEAR UCA-BGM-JUST NORTH OF IPT. A BAND OF
SHOWERS WITH ISOLATED THUNDERSTORMS CONTINUES ALONG THE FRONT...
WITH RADAR ESTIMATED RAINFALL AMOUNTS OF UP TO 1 TO 2 INCHES IN
LOCALIZED HEAVIER DOWNPOURS. WITH A VERY MOIST ATMOSPHERE AND WEAK
SHEAR PROFILES IN PLACE... FLASH FLOODING WILL REMAIN A THREAT UNTIL
THE FRONT MOVES OFF TO THE SOUTHEAST. BASED ON THIS WILL KEEP THE
FLASH FLOOD WATCH GOING THRU EARLY EVENING FOR MOST OF NE PA AND THE
WESTERN CATSKILLS... AND THRU THE NIGHT FOR PIKE... WAYNE AND
SULLIVAN COUNTIES.
THE MAIN QUESTION WITH THIS FORECAST PACKAGE WILL BE HOW FAR SOUTH
THE FRONT GETS ON SATURDAY... AND HOW SOON OVERUNNING MOISTURE
RE-DEVELOPS ON SUNDAY. THE ETA AND GFS ARE NOW IN PRETTY GOOD
AGREEMENT THAT THE FRONT GETS FAR ENOUGH SOUTH ON SATURDAY SO THAT
MOST OF THE FORECAST AREA WILL HAVE A DRY DAY. WILL KEEP A LOW CHC
POP GOING ACROSS THE FAR SOUTH... WITH DRY WEATHER FARTHER NORTH.
UPPER TROF DIGGING INTO THE CENTRAL PLAINS THEN ALLOWS THE UPPER
FLOW TO SHIFT TO THE SW OVER OUR AREA BY SUNDAY... WHICH RESULTS IN
AN INVERTED SURFACE TROF DEVELOPING NEAR THE MID-ATLANTIC COAST...
AND OVERUNNING PRECIPITATION DEVELOPING NORTHWARD. THE ETA AND GFS
ARE IN GOOD AGREEMENT SHOWING A COOL RAIN SPREADING NORTH ACROSS PA
TOWARD SOUTHERN NY ON SUNDAY... WITH ONLY THE NGM SHOWING DRY WX
CONTINUING SUNDAY. AT THIS TIME WILL SIDE WITH THE ETA/GFS AND GO
WITH HIGH CHC POPS FOR NY ON SUNDAY WITH LIKELY POPS ACROSS NE PA.
&&
.LONG TERM (MONDAY-FRIDAY)...
VERY UNSETTLED PATTERN CONTINUES NEXT WEEK AS A LARGE UPPER-LEVEL
TROUGH OVER THE MIDWEST MOVES SLOWLY EAST... HIGH PRESSURE ANCHORS
ITSELF OFF THE EAST COAST... AND A LARGE... UNSEASONABLY COOL
AIRMASS OVER THE GREAT LAKES AND SOUTHERN CANADA IS OVERRUN BY
INCREASING AMOUNTS OF LOW-LEVEL MOISTURE. WILL BE GOING WITH CHC
POPS JUST ABOUT EVERY PERIOD THROUGH THE MIDDLE OF THE WEEK.
UNSEASONABLY COOL AIRMASS PLUS LOTS OF CLOUDINESS INSURES THAT HIGH
TEMPERATURES WILL REMAIN WELL BELOW NORMAL THRU MID-WEEK.
.AVIATION...
SHOWERS WILL BE EAST OF BGM BY 21Z... AND EAST OF AVP BY AROUND 23Z.
CLEARING WILL THEN OCCUR FROM NORTHWEST TO SOUTHEAST... WITH ALL TAF
SITES CLEARING BY LATE TONIGHT. EXPECT PATCHY AREAS OF LIGHT FOG
LATE TONIGHT... BUT WIDESPREAD DENSE FOG IS NOT EXPECTED AS DRYER
AIR WILL BE MOVING IN AT LOW LEVELS. VFR CONDITIONS EXPECTED ON
SATURDAY.
