AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
530 PM EDT THU JUL 5 2012

.SYNOPSIS...
HOT SUMMERTIME WEATHER WILL PREVAIL ACROSS CENTRAL PENNSYLVANIA
INTO THE WEEKEND. A COLD FRONT WILL DROP SOUTHWARD THROUGH THE
KEYSTONE STATE LATE SUNDAY...WITH MORE IN THE WAY OF NORMAL
TEMPERATURES FOR NEXT WEEK. MONDAY INTO WED LOOKS TO BE MAINLY
DRY FOR NOW...BUT THE LATER PART OF NEXT WEEK COULD SEE A RETURN
TO MORE HUMID CONDITIONS WITH A CHANCE OF SHOWERS AND STORMS.

&&

.NEAR TERM /UNTIL 11 PM THIS EVENING/...
A WEAKENING COLD FRONT IS MOVING INTO NORTHERN PA EARLY THIS
AFT...ACCOMPANIED BY A WIND SHIFT TO THE NW AND A DROP IN DWPTS.
ALL MDL DATA STALLS THIS FRONT OUT ACROSS SOUTHWEST PA LATER
TODAY. THIS BOUNDARY...ALONG NE PERIPHERY OF EXPANSIVE SOUTH-
CENTRAL U.S. UPPER RIDGE...WILL SERVE AS THE FOCUS FOR TSRA
INTO THIS EVENING.

SOME NEW STORMS FORMING OVER SOUTHERN MI AT THE CURRENT TIME.
EXPECT MOST OF THESE TO STAY SW OF OUR AREA...BUT SOME COULD
CLIP THE SW PART OF THE CWA...HIGHEST POPS HERE THIS EVENING.

&&

.SHORT TERM /11 PM THIS EVENING THROUGH 6 PM FRIDAY/...
ANY TSRA ACROSS THE S TIER SHOULD DISSIPATE BY LATE EVENING...
AS TEMPS COOL. WITH SLIGHTLY LOWER DEWPOINTS IN PLACE...AS WEAK
HIGH PRESSURE TRIES TO BUILD SOUTHWARD FROM SOUTHERN ONTARIO...
THIS SHOULD ALLOW TEMPS TO BE COOLER THAN LAST NIGHT. MANY SPOTS
LAST NIGHT STAYED WELL INTO THE 70S.

TEMPS WILL BE HOT ON FRIDAY. HEAT ADVISORIES MAY BE NEEDED ACROSS
THE SOUTH. LIMITING FACTOR WILL BE THE DEWPOINT. TEMPS SATURDAY
MAY BE HOT ENOUGH ACROSS THE SE TO BE IN ADVISORY LEVEL...EVEN
IF DEWPOINTS ARE NOT THAT HIGH...SEE LONG TERM SECTION BELOW.

AT THIS POINT...EXPECT TEMPS AT MID LVLS TO CAP OFF ANY SHOWERS
OR STORMS ON FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
SHORTWAVE TROUGH EMBEDDED WITHIN BELT OF STRONGER WLYS CONFINED
TO THE U.S./CANADIAN BORDER WILL MOVE THROUGH ONTARIO AND QUEBEC
BEFORE TURNING SEWD INTO THE NERN STATES FRIDAY NIGHT INTO
SATURDAY. THIS FEATURE WILL BREAK DOWN/FLATTEN THE NERN PERIPHERY
OF THE HOT UPPER RIDGE IN THE CENTRAL PLAINS AND FORCE A SFC COLD
FRONT SEWD THRU PA BY LATE SUNDAY.

MODELS SHOW MUCH OF THE SHOWER AND THUNDERSTORM ACTIVITY TO
BE BEHIND THE FRONT. STILL WOULD EXPECT STORMS TO FORM AHEAD
OF THE FRONT.

THE D3 SPC CONVECTIVE OUTLOOK PLACES THE AREA IN A CATEGORICAL
SLIGHT RISK...WITH POTENTIAL FOR STRONG TO SEVERE THUNDERSTORM
DEVELOPMENT IN MOIST/UNSTABLE AIR MASS ALONG/AHEAD OF SWD
ADVANCING COLD FRONT. THE D3 /SAT/ OUTLOOK COVERS THE ENTIRE CWA.

THE HEAT WILL PEAK ON SATURDAY WITH 850MB TEMPS OF +20-25C
SUPPORTING NEAR RECORD TEMPERATURES IN THE LOW-MID 90S IN THE
WEST/CENTRAL COUNTIES...TO AROUND 100F IN THE SE/LWR SUSQ VLY.
TABULAR ECM NUMBERS ARE A FEW DEGREES WARMER THAN THE GFS...AND
HAVE LEANED IN THAT DIRECTION. HEAT INDEX VALUES /APPROACHING OR
EXCEEDING THE CENTURY MARK/ WILL ALSO BE A CONCERN THRU THE PERIOD
AND HAVE HIGHLIGHTED THIS (ALONG WITH THE D3 SLIGHT RISK) IN THE
HWO. HEAT ADVISORIES MAY BE NEEDED FOR SAT PARTICULARLY IN THE
SOUTHEAST ZONES.

ABOVE AVERAGE CONFIDENCE EXISTS IN A PATTERN SHIFT TOWARD A
POSITIVE PNA CONFIGURATION...AS THE HOT CENTRAL CONUS UPPER RIDGE
RETROGRADES WWD AND UPPER TROUGH AMPLIFIES IN THE NERN U.S. THIS
WILL BRING A COOL DOWN IN TEMPERATURES TO SEASONAL CLIMATE NORMALS
AND PROVIDE RELIEF FROM THE RECENT STRETCH OF HIGH HEAT AND
HUMIDITY.

&&

.AVIATION /22Z THURSDAY THROUGH TUESDAY/...

MAIN AVIATION CONCERN FOR THIS EVENING IS A NARROW LINE OF
SCATTERED STORMS FROM NEAR CLEARFIELD SE TO ABOUT YORK. SOME OF
THESE COULD WANDER OVER A TERMINAL AND CAUSE BRIEF IFR WITH A
DOWNPOUR AND GUSTY WINDS.

OTHERWISE...HIGH PRESSURE AND ASSOCIATED DRY AIR MASS PASSING
ACROSS UPSTATE NY AND NORTHERN PA WILL PRODUCE MAINLY VFR CONDS
ACROSS THE REGION. HOWEVER...THE SOUTHERN HALF OF THE
STATE...WHERE DEWPOINTS ARE HIGHER...WILL REMAIN SUSCEPTIBLE TO A
BRIEF TSRA.

OUTLOOK...
FRI...NO SIG WX EXPECTED.
SAT...SCT PM THUNDERSTORM IMPACTS POSS.
SUN...SCT THUNDERSTORM IMPACTS POSS...ESP SOUTH.
MON...ISOLATED SHOWER OR THUNDERSTORM POSSIBLE ACROSS THE SOUTH
EARLY...OTHERWISE NO SIG WX EXPECTED.
TUE...NO SIG WX EXPECTED.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
NONE.
