AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
827 PM EDT FRI JUN 29 2012

.SYNOPSIS...
HOT AND MUGGY CONDITIONS WILL PREVAIL OVER THE UPCOMING WEEKEND
AND INTO NEXT WEEK...AS A WEAK COLD FRONT STALLS NEAR THE
PENNSYLVANIA...MARYLAND BORDER.

&&

.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
LATEST RADAR AND SATL IMAGERY SHOW WELL DEFINED MCS/DERECHO MOVING
ACROSS SWRN PA/WV AND NRN MD. NRN EDGE OF CONVECTION IS/WILL CLIP
SWRN CWA COUNTIES WITH SVR WATCH 438 IN EFFECT TIL 1 AM/05Z. WHILE
LEADING EDGE OF DERECHO/WIDESPREAD DAMAGING WINDS WILL PASS SOUTH
OF PA...NRN EDGE OF THE CONVECTIVE LINE WILL MOVE INTO SOMERSET
COUNTY BY 01Z.

ALSO OF CONCERN...ISOLD TO SCT CONVECTION HAS BEEN DEVELOPING ALONG
A WEST TO EAST AXIS/SFC WARM FRONT OVER THE SOUTHERN TIER
COUNTIES...IN THE WARM AND HUMID AIRMASS /SFC TEMPS IN THE 80S AND
DEWPOINTS IN THE MID 60S/. WEST TO EAST TRAINING OF CELLS WILL
PRESENT A FLASH FLOOD THREAT...MAINLY FOR THE NEXT HOUR OR TWO
UNTIL THE MAIN MCS PASSES THROUGH. ALSO WATCHING CELLS FOR SIGNS
OF ROTATION...AS THEY ARE FORMING ALONG THE SFC WARM FRONT WHICH
HAS BEEN SHOWN TO INCREASE PROBABILITY OF TORNADO FORMATION
WITHIN SUPERCELL STORMS.

&&

.SHORT TERM /MIDNIGHT THROUGH 6 PM SATURDAY/...
FAIR BUT MUGGY CONDITIONS WILL CONTINUE OVERNIGHT OVER ABOUT THE
SRN HALF OF THE REGION. DRIER AIR WILL MAKE FOR MORE COMFORTABLE
SLEEPING OVER THE NORTHERN TIER.

ANOTHER DAY OF HEAT WITH SURGING HUMIDITY IS IN STORE FOR
SATURDAY. APPARENT TEMPERATURES WILL REACH WELL INTO THE 90S FOR
THE SOUTHERN HALF OF THE COMMONWEALTH AND HEAT ADVISORIES REMAIN
IN EFFECT THROUGH SATURDAY EVENING FOR MOST OF THE SOUTHEAST.

BIGGEST QUESTION FOR SATURDAY WILL BE IF WE SEE ANOTHER MCS ROTATE
THRU THE NRN EDGE OF THE MID LATITUDE RIDGE. NEW NAM BRINGS AN
AREA OF RAIN THROUGH SAT AFTERNOON...WHILE THE NEW GFS IS MORE
AMORPHOUS WITH THE QPF IT GENERATES. THE GEFS/SREF BOTH SHOW A
PRETTY GOOD CHANCE OF RAIN SO IT LOOKS LIKE A GOOD IDEA TO RAISE
AFTERNOON POPS A BIT TO AT LEAST COVER THE CHANCE OF STORMS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
A BROAD UPPER TROUGH WILL EXTEND FROM THE UPPER MS VALLEY EWD ACROSS
THE GREAT LAKES AND INTO THE NERN STATES...WITH EMBEDDED VORTICITY
MAXIMA TRANSLATING EWD WITHIN FAST WESTERLY FLOW ALOFT ALONG THE
US/CANADIAN BORDER. ONE DISTINCT SHORTWAVE TROUGH IS EXPECTED TO
BE OVER THE IND/OH AREA...AND WILL SPREAD EWD ACROSS
PA INTO THE DELMARVA BY 12Z SUN. THIS FEATURE WILL COMBINE WITH
AMPLE MOISTURE AND INSTABILITY ON THE NRN PERIPHERY OF THE HOT SE
RIDGE TO PRODUCE POTENTIALLY SIGNIFICANT MCS/SEVERE WIND. THE DY2
SPC SLGT RISK COVERS NEARLY ALL OF THE CWA EXCEPT FOR THE NRN
TIER.

THE MODELS AND ENSEMBLES OFFER A REASONABLY SIMILAR AND SEEMINGLY
REASONABLE LARGER SCALE FLOW PATTERN FROM THE ERN PACIFIC ACROSS
NORTH AMERICA.  THIS FLOW IS  HIGHLIGHTED AT MID-LATITUDES BY MEAN
MID-UPPER LEVEL TROUGHS JUST OFF THE US WEST COAST AND OVER THE
NERN US...SANDWICHING A VERY HOT AND PERSISTENT SUMMERTIME RIDGE
EXPANDED OUT FROM THE CENTRAL US. THIS IS ESSENTIALLY AN EXTENSION
OF THE SHORT TERM WEATHER PATTERN TO A LARGE DEGREE WITH SLIGHT
RETROGRESSION OF THE UPPER RIDGE.

HPC D3-7 PROGS SHOW RETREATING SFC HIGH MON FOLLOWED BY PCPN
CHANCES ASSOCD WITH FRONTAL SYSTEM AROUND MID-WEEK.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
LATEST RADAR AND SATL IMAGERY SHOW WELL DEFINED MCS/AREA OF
RAIN AND STRONG TO SEVERE THUNDERSTORMS MOVING ACROSS SWRN PA/WV
AND NRN MD. THIS AREA WILL AFFECT MAINLY SRN TAF SITES /JST AND
AOO/ THROUGH THE EVENING HOURS WITH REDUCED IFR VSBYS AND CIGS AND
GUSTY WINDS IN EXCESS OF 30KTS.

ISOLD SHOWERS/TSRA WILL MOVE TOWARD MDT/CXY AND LNS AFTER 02Z AND
CONTINUE THROUGH 06Z.

ELSEWHERE VFR CONDS SHOULD CONTINUE OVERNIGHT WITH JUST LOWERING
HIGH AND MID CLOUDS DECKS /AND MAYBE A BRIEF SHOWER AT UNV/ ASSOCIATED
WITH THE CONVECTIVE SYSTEM. EXCEPTIONS WILL BE LATER TONIGHT THRU
JUST AFTER DAWN SATURDAY AS SOME THIN FOG OR HAZE REDUCES THE VSBY
TO BETWEEN 3-5 MILES IN SOME AREAS. THIS SHUD IMPROVE BY MID
MORNING AS WE MIX OUT.

EXPECT A CONTINUATION OF MAINLY VFR CONDITIONS SATURDAY AS A VERY
SUMMER-LIKE AIRMASS REMAINS IN PLACE OVER CENTRAL PA.

SATURDAY AFTERNOON HAS THE POSSIBILITY OF LOCALLY REDUCED
CONDITIONS WITH THE EXPECTATIONS OF SOME DIURNAL SHOWERS AND
STORMS DEVELOPING. TIMING AND LOCATION REMAIN QUESTIONABLE...BUT
REDUCED CONDITIONS WOULD REMAIN A POSSIBILITY INTO THE EVENING
WITH ANY ACTIVITY THAT DOES MANAGE TO FORM.

OUTLOOK...
FRI NIGHT...MAINLY VFR. ISOLD SHOWERS/TSTMS WITH LOCAL
RESTRICTIONS.

SAT-MON...MAINLY VFR. SLIGHT CHC OF A SHOWER/TSTM. FOG AND HZ
EARLY.

TUE-WED...MAINLY VFR BUT WITH RESTRICTIONS IN ANY SHOWERS OR
STORMS THAT FORM.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
HEAT ADVISORY UNTIL 8 PM EDT SATURDAY FOR PAZ028-035-036-056-
