Area forecast discussion, Jun 18, 2:48 PM EDT, 4 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
248 PM EDT THU JUN 18 2015

.SYNOPSIS...
HOT SUBTROPICAL RIDGE SPREADING OVER THE SOUTHERN UNITED STATES
WILL KEEP NORTHERN STREAM FRONTAL SYSTEMS STALLED OUT ACROSS THE
NORTHEAST AND MID ATLANTIC STATES INTO NEXT WEEK. EXPECT PERIODS
OF RAIN AND THUNDERSTORMS TO OCCUR IN THIS PATTERN.

&&

.NEAR TERM /THROUGH TONIGHT/...
SCATTERED SHOWERS DEVELOPING ON RADAR...FEW HAVE ANY LIGHTING
STRIKES BUT EXPECT THAT TO CHANGE FOR REMAINDER OF AFTERNOON AND
EVENING. HRRR RUNS CONTINUE TO SHOWER SCATTERED SHOWERS AND
THUNDERSTORMS AHEAD OF APPROACHING COLD FRONT. WITH TD VALUES IN
THE LOWER 70S IN SPOTS EXPECTED SOME LOCALLY HEAVY SHORT LIVED
DOWNPOURS. FRONT ARRIVES LATER THIS EVENING WITH A SCATTERED LINE
OF SHOWERS AND THUNDERSTORMS. BEHIND THIS WILL BE DRIER AIR AS THE
SURFACE FRONT PUSHES THROUGH.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
SFC HIGH WITH DRIER AIR BUILDS INTO CWA FRIDAY. FRONT WILL NOT BE
TOO FAR SOUTH OF PA/MD BORDER AND AN ISOLATED SHOWERS IS POSSIBLE
THERE. COOL NIGHT FRIDAY NIGHT WITH TEMPERATURES BOTTOMING OUT IN
THE 50S FOR A LARGE PART OF THE AREA AND EVEN SOME 40S IN THE
NORTHERN MOUNTAINS.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
HIGH PRES RIDGE FROM NEW ENGLAND DOWN THROUGH NY AND PA. REMNANTS
OF BILL MOVING INTO OHIO WITH A WARM FRONT SPREADING
PRECIPITATION INTO SOUTHWEST PA. CLOUDS WILL BE INCREASING IN
ADVANCE OF THIS INTO THE NIGHTTIME HOURS WITH PRECIPITATION MOVING
INTO WESTERN PA AND SPREADING EAST. FORECAST HAS THE CENTER OF
WHAT WILL BE LEFT OF BILL MOVING EAST ALONG THE MASON-DIXON LINE
AND THEN OFF THE EAST COAST BY SUNDAY EVENING. A WIDESPREAD ONE TO
TWO INCHES OF RAIN IS POSSIBLE ACROSS THE SOUTHERN HALF OF THE
STATE WITH LESS TO THE NORTH OF HERE. HEAVY DOWNPOURS WITH ANY
THUNDERSTORMS COULD PRODUCE LOCALLY HIGHER AMOUNTS AND SO THIS IS
STILL A CONCERN SATURDAY NIGHT AND SUNDAY. HOWEVER...MOST OF THE
RAINFALL WILL BE BENEFICIAL FOR DROUGHT RELIEF. THE MAIN CONCERN
REMAINS FOR POTENTIAL OF LOCALIZED FLOODING IF THUNDERSTORMS
REPEATEDLY MOVE OVER THE SAME LOCATIONS.

CLOUDS AND HUMIDITY WILL LINGER BEHIND UNTIL THE COLD FRONT SWEEPS
THROUGH SUNDAY NIGHT. THE FRONT MAY TRIGGER ADDITIONAL SHOWERS AND
THUNDERSTORMS SUNDAY AFTERNOON AND NIGHT. UPR LEVEL RIDGE SETS UP
OVER THE CENTRAL U.S. WITH NW FLOW ACROSS PA BEGINNING MONDAY INTO
TUESDAY. MODEL UNCERTAINTY INCREASES FOR MID WEEK ON TIMING AND
STRENGTH OF THE NEXT SYSTEMS. GENERALLY LOOKING AT A VIGOROUS LOW
PRESSURE CENTER MOVES FROM THE GREAT LAKES INTO PA MONDAY NIGHT
INTO TUESDAY MORNING SPREADING MORE SHOWERS ACROSS THE STATE. AN
ASSOCIATED COLD FRONT SWEEPS THROUGH WITH WEATHER CLEARING BY
TUESDAY NIGHT. HIGH PRESSURE BUILDS IN FOR WEDNESDAY BRINGING
COOLER NIGHTS AND DRIER WEATHER. BUT THE ACTIVE PATTERN CONTINUES
WITH THE NEXT WAVE APPROACHING SW PA WITH A WARM FRONT AND SHOWERS
POSSIBLE AGAIN ON THURSDAY.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SCT CONVECTION FOR THIS AFTERNOON AND EVENING. MVFR TO IFR
CHANCES WILL ONCE AGAIN BE POSSIBLE TONIGHT INTO TOMORROW
