AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
241 PM EDT MON JUN 1 2015

.SYNOPSIS...

LOW PRESSURE WILL DRIFT SLOWLY TO THE MID ATLANTIC COAST OVER THE
NEXT COUPLE OF DAYS. WEAK HIGH PRESSURE WILL BRING A BRIEF RESPITE
FROM THE SHOWERS WEDNESDAY BEFORE UNSETTLED WEATHER MAKES A RETURN
FOR THE END OF THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...

A WEAK LOW INVOF MARTINSBURG WV HAS MOVED ALMOST NOT AT ALL SINCE
EARLY MORNING. BETWEEN THE SLOW MOVING LOW AND Q-STATIONARY FRONT
EXTENDING EASTWARD OFF THE COAST...BROAD LOW LEVEL CONVERGENCE IS
STARTING TO TAKE ADVANTAGE OF CAPES BETWEEN 500-1500J INITIATING
SCATTERED CONVECTION FROM AROUND SELINSGROVE DOWN TO THE FRANKLIN
COUNTY BORDER WITH MARYLAND.

BIGGEST THREAT REMAINS LOCALIZED DOWNPOURS IN THE VERY HUMID
AIRMASS WITH PWATS IN EXCESS OF 1.5". HRRR TARGETS THE SERN
ZONES...WHERE THE FLASH FLOOD WATCH IS...THROUGH LATE AFTERNOON
AND INTO THE EVENING...SO THE WATCH LOOKS WELL PLACED AT THIS
TIME.

FOR MUCH OF THE REMAINDER OF PA IT WILL REMAIN RATHER GLOOMY AND
COOL TO START THE FIRST MONTH OF THE TRADITIONAL SUMMER. BROAD
TROFFING ALOFT WILL MEAN THAT A STRAY SHOWER CANNOT BE RULED OUT
EVEN OVER THE CENTRAL AND NORTHERN MOUNTAINS...BUT THE BEST
CHANCES FOR RAIN WILL REMAIN SERN AREAS CLOSER TO THE FRONTAL
FORCING AND DEEPEST INSTABILITY.

LOWS WILL RANGE FROM THE MID 40S OVER THE NW TO AROUND 60 OVER THE
SE.

&&

.SHORT TERM /TUESDAY/...

THE FRONTAL WAVE WILL SETTLE SOUTH AND FINALLY MOVE OFF THE
COAST...SO TUESDAY WILL SEE GENERALIZED BUT GRADUAL IMPROVEMENT. A
PERSISTENT LOW LEVEL EASTERLY FLOW WILL KEEP A FAIR AMOUNT OF
CLOUDS AROUND AND SOUTHERN AREAS COULD SEE SOME LINGERING SHOWERS
OR EVEN SOME DRIZZLE...BUT DRIER AIR SHOULD CONTINUE TO FILTER
DOWN FROM THE NORTH LEAVING ALL BUT THE FAR SOUTH MAINLY DRY BY
AFTERNOON.

IT WILL REMAIN CHILLIER THAN NORMAL WITH HIGHS ONLY AVERAGING IN
THE 60S.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
SRN STREAM UPPER TROF WILL MOVE SLOWLY EAST THROUGH THE TN
VALLEY/SE STATES THROUGH THE WEEK. NORTHERN STREAM
JET...FLATTENING AMPLITUDE THAN THE SRN STREAM TROF...WILL LAY
JUST TO THE NORTH OF PA WITH A COUPLE SHORTWAVES MOVING THROUGH
DURING THE PERIOD. THIS WILL PUT PA RIGHT IN THE SQUEEZE ZONE
BETWEEN THE TWO SYSTEMS. THE TREND FOR TODAY IS A DECIDEDLY WETTER
FORECAST... AS THE SLOW MOVING SRN STREAM TROF MAKES IF DIFFICULT
FOR SFC FRONTS TO CLEAR THE REGION. THIS MADE IT HARD NOT TO
INCLUDE AT LEAST ISOLATED CHANCES OF SHOWERS/TSTMS FOR MUCH OF THE
PERIOD. THE BEST CHANCE FOR A DRIER PD IS EARLY IN THE WEEK WITH
COOLER THAN NORMAL TEMPS. WARM TEMPS AND MORE HUMID WEATHER WILL
RETURN FROM MID WEEK ONWARD.

&&

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

WEAK SFC LOW AND ATTENDANT EAST-WEST ORIENTED FRONTAL ZONE WILL
PUSH SETTLE SEWD ACROSS FAR SERN PA TODAY. IT WILL PROVIDE THE
FOCUS FOR CONVECTION THAT IS BEGINNING TO FIRE OVER THE LOWER SUSQ
VALLEY...WITH ONE OR MORE ROUNDS OF TSTMS EXPECTED TO CONTINUE
INTO TONIGHT.

NORTH OF THE LOW AND FRONTAL ZONE...WIDESPREAD MVFR/IFR
CONDITIONS CONTINUE WITH ONLY MARGINAL IMPROVEMENT EXPECTED FOR
THE REMAINDER OF THE DAY. THE EAST-NORTHEAST FLOW WILL KEEP IT
MOIST IN THE LOW LEVELS SO CEILINGS ARE EXPECTED TO DETERIORATE
ONCE AGAIN OVERNIGHT.

OUTLOOK...

TUE...A.M IFR/MVFR CIGS BCMG MVFR/VFR IN THE AFTN. SCT SHRA
AND TSTMS FAR SRN/SERN AIRFIELDS.

WED...VFR.

THU-SAT...REDUCED CONDITIONS PSBL WITH SCT SHOWERS/ISOLD TSTMS.
