AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
146 PM EDT MON JUN 28 2010

.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA TONIGHT...WITH SCATTERED SHOWERS
AND THUNDERSTORMS PRECEDING IT...THROUGH THE EVENING HOURS. MUCH
COOLER TEMPERATURES WILL FOLLOW FOR TUESDAY AND WEDNESDAY...BEHIND THE FRONT.
HIGH PRESSURE WILL ALSO BUILD IN...BRINGING MAINLY DRY WEATHER.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
UPDATED AT 125 PM... TWO MAIN AREAS OF CONVECTIVE DEVELOPMENT THIS
AFTERNOON. ONE IS OVER WESTERN NY...AHEAD OF THE MAIN COLD FRONT
ACROSS ONT AND LOWER MI. THE OTHER IS FORMING OVER THE DELMARVA
REGION AND SOUTHEAST PA. THE FORMER AREA OF SHOWERS AND STORMS
SHOULD CROSS MUCH OF THE FORECAST AREA LATE THIS AFTERNOON AND
EARLY EVENING...WITH PERHAPS SLIGHT WEAKENING IN INTENSITY...AS
THE AIR MASS ACROSS CENTRAL NY/NORTHEAST PA HAS BEEN SOMEWHAT
CLOUDIER/MORE STABLE SO FAR TODAY. SINCE THERE IS STILL A SMALL
WINDOW FOR FURTHER DESTABILIZATION LATE THIS AFTERNOON...AND THIS
AREA IS CLOSER TO THE BETTER HEATING THAT HAS OCCURRED DOWN OVER
THE COASTAL PLAIN...WE STILL MENTION THE POSSIBILITY OF LOCALLY
HEAVY RAIN AND GUSTY WINDS...ACROSS SECTIONS OF NORTHEAST PA AND
THE WESTERN CATSKILLS.

LATER TONIGHT...ONCE THE FRONT CROSSES THE REGION...DRIER/MORE
STABLE AIR WILL BUILD IN...WITH SHOWER COVERAGE DECREASING
ACCORDINGLY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
UPDATED AT 135 PM... A MUCH COOLER AIR MASS WILL PROGRESSIVELY
INVADE THE NORTHEASTERN U.S. TUE THROUGH WED. OVERALL...THIS AIR
MASS WILL ALSO BE FAIRLY DRY...SO A MINIMUM OF PRECIPITATION IS
EXPECTED. HOWEVER...A COUPLE OF UPPER-LEVEL WAVES WILL ROTATE
ACROSS UPSTATE NY...AND COULD TOUCH OFF SCATTERED SHOWER ACTIVITY
OVER THE NORTHERN FINGER LAKES...MOHAWK VALLEY...SOUTHERN TUG
HILL...AND CATSKILL ZONES...ESPECIALLY FROM TUE NIGHT INTO WED
EVENING.

BY THU...AN AMPLIFIED CLOSED LOW FOR THIS TIME OF YEAR...WILL
BEGIN TO LIFT OUT ACROSS THE CANADIAN MARITIMES...WITH RISING
HEIGHTS ACROSS NY/PA...AND MAINLY SUNNY SKIES.

AS MENTIONED ABOVE...THIS PERIOD WILL FEATURE BELOW NORMAL TEMPS
FOR EARLY JULY...WITH HIGHS IN THE UPPER 60S TO LOWER 70S...AND
LOWS IN THE 40S AND LOWER 50S.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
VERY QUIET XTNDD PD AS A LRG HIPRES BLDS IN SFC AND ALOFT AND
GIVES THE AREA DRY WX. BY SUN...+590DM H5 HI OVER WRN PA AND H8
TEMPS APCHG 20C. SO...TEMP TREND WILL SHOW WRMG THRU THE PD WITH
HI/S WELL ABV NRML BY THE END OF THE PD. GNRLY FLWD HPC GUID FOR
TEMPS BUT DID DIAL BACK A BIT IN THE TEMPS NEAR THE END TO BLEND
BETTER WITH THE SRNDG OFFICES AND THE LATEST MEX GUID.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...

CONV FIRING THIS AFTN WILL BRING SCT SHWRS AND TRWS TO THE TAF
SITES FOR THE NEXT FEW HRS. IN GNRL...PCPN SHD BRING TEMP MVFR
CONDS AT WORST AS THEY PAST. COLD FNT IS STILL WELL BACK OVER THE
GREAT LAKES SO DO NOT XPCT RAPID CLRG OVRNGT INSTEAD EXPCT THE
LINGERING MOISTURE TO BRING MVFR CIGS AND VSBY WITH FOG. DRIER AIR
ENTERS THE AREA ON TUE ON WLY WINDS...DROPPING THE DEW PTS AND A
GRADUAL RETURN TO VFR CONDS BY MID TO LATE MRNG.

OUTLOOK...

TUES THRU SAT...MOSTLY VFR OTHER THAN SOME MORNING IFR FOG AT ELM.
