Tornado in Pennsylvania, July 9, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
405 PM EDT THU JUL 9 2015

.SYNOPSIS...
A WARM FRONT IS MOVING SLOWLY NORTH ACROSS THE STATE THIS
AFTERNOON...PLACING MUCH OF CENTRAL AND SOUTHEAST PENNSYLVANIA IN
THE WARM UNSTABLE SECTOR. STRONG TO SEVERE THUNDERSTORMS ARE
POSSIBLE THIS AFTERNOON AND EVENING...ESPECIALLY ACROSS THE
EASTERN HALF OF THE STATE AS A WAVE OF LOW PRESSURE MOVES ALONG
THE PENNSYLVANIA...NEW YORK BORDER AND DRAGS A TRAILING COLD FRONT
EAST ACROSS THE COMMONWEALTH. HIGH PRESSURE WILL RETURN FOR FRIDAY
AND SATURDAY BRINGING SLIGHTLY COOLER AND NOTABLY LESS HUMID
WEATHER WITH LITTLE CHANCE FOR RAIN. A CHANCE OF SHOWERS AND
THUNDERSTORMS RETURN LATE SUNDAY AND MONDAY.

&&

.NEAR TERM /UNTIL 10 PM THIS EVENING/...
SURFACE LOW IN VICINITY OF KERI EARLY THIS AFTERNOON HAS LIFTED
THE WARM FRONTAL BOUNDARY AHEAD OF IT TO NEARLY THE PA/NY
BORDER...PUTTING MUCH OF CENTRAL PA IN THE MOIST AND INCREASINGLY
UNSTABLE WARM SECTOR. LITTLE IN THE WAY OF RAINFALL OCCURRED THIS
MORNING OVER NORTHERN MTNS /FLOOD WATCH AREA/...BUT AS THE LOW
PRESSURE WAVE CONTINUES TO MOVE EASTWARD AND TAPS INTO HIGH PWAT
AIRMASS...MODERATE TO LOCALLY HEAVY RAINS WILL REMAIN POSS THROUGH
THE AFTERNOON HOURS - ESPECIALLY IF EFFICIENT RAIN-PRODUCING
BANDS CAN ALIGN AND TRAIN OVER SAME AREAS. FF GUIDANCE REMAINS ON
THE LOW SIDE /ONLY AROUND 1.3-1.5 INCHES ACROSS MANY LOCATIONS/.

ACROSS CENTRAL AND SOUTHERN PORTIONS OF CWA...CONFIDENCE CONTINUES
TO INCREASE IN POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS THIS
AFTERNOON INTO EVENING. SURFACE DEWPOINTS ALREADY CREEPING INTO
THE LOW 70S WITH DIABATIC HEATING CONTINUING TO ENHANCE CAPE. ADD
IN INCREASING LOW LEVEL SHEAR AS 850MB WINDS INCREASE TO 40 KTS
ALONG WITH A SHORTWAVE WORKING IN FROM SE OH AND INGREDIENTS LOOK
TO BE IN PLACE FOR STRONG TO SEVERE TSTMS WITH DAMAGING WINDS TO
DEVELOP AND LIKELY MORPH INTO A SQUALL LINE AS THEY MOVE EAST.
FAVORABLE TIME OF DAY...PROXIMITY OF WARM FRONT...WEAK LEE
TROUGHING AND LOCALIZED TERRAIN ENHANCEMENTS OF LLVL SHEAR WILL
ENHANCE POTENTIAL FOR ROTATING UPDRAFTS...AND ISOLATED BRIEF
TORNADOES INVOF OF BROKEN-S SIGNATURES OR ANY CELLS THAT CAN
ISOLATE THEMSELVES FROM THE MAIN LINE. BIGGEST THREAT CONTINUES TO
BE ALONG AND SOUTH OF A CORRIDOR FROM KFIG TO KIPT TO KAVP.

HIGH TEMPERATURES THIS AFTERNOON SHOULD BE SIMILAR TO WEDNESDAY
/LOW-MID 70S NEAR THE PA/NY BORDER...UPPER 70S NEAR THE I-80
CORRIDOR...AND 80-85F ACROSS THE SOUTH/.

&&

.SHORT TERM /10 PM THIS EVENING THROUGH 6 PM FRIDAY/...
THUNDERSTORMS WILL BE QUICKLY EXITING EAST ACROSS THE DELAWARE
VALLEY OF FAR EASTERN PENN AROUND MIDNIGHT. SWWD TRAILING COLD
FRONT FROM THE SFC LOW OVER THE CATSKILL REGION WILL MEANS THAT
ANOTHER SHOWER OR TWO WILL BE POSSIBLE...BUT ADDITIONAL RAINFALL
FROM 02Z ON WILL BE LESS THAN 0.10 OF AN INCH.

DEWPOINTS WILL FALL OFF STEADILY OVERNIGHT AND DIP TO SLIGHTLY
BELOW NORMAL BY DAYBREAK FRIDAY ACROSS FAR NRN PENN. LLVL MOISTURE
WILL LIKELY WAIT TO BE SCOURED OUT UNTIL LATER FRIDAY MORNING
ACROSS SOUTHERN PENN DUE TO THE VERY LATE NIGHT TIMING OF THE
SFC CFRONTAL PASSAGE AND LIGHT WIND...EVEN RIGHT IN ITS WAKE.

LOW TEMPS EARLY FRIDAY MORNING WILL VARY FROM THE MID 50S ACROSS
THE NRN TIER...TO THE UPPER 60S THROUGHOUT MOST OF THE LOWER SUSQ
VALLEY.

THE LARGE SCALE PATTERN FCST OVER THE LOWER 48 INTO NEXT WEEK
REMAINS ON TRACK...WITH A MEAN TROUGH NEAR THE WEST COAST...
RETROGRADING UPPER RIDGE OVER THE SOUTHEAST/SOUTH-CENTRAL U.S.
EVENTUALLY SETTLING NEAR THE TX PANHANDLE AND EXTENDING NWD OVER
THE ROCKIES AND WRN HIGH PLAINS...AND AN AMPLIFYING TROUGH OVER
THE ERN HALF OF THE CONUS DOWNSTREAM OF THE RIDGE.

CONFIDENCE IN A 48 HOUR/2-DAY PERIOD OF DRY WEATHER FROM FRIDAY INTO
SATURDAY CONTINUES THROUGH THE MOST RECENT MODEL RUNS...WITH THE
LATEST MODEL AND ENSEMBLE GUIDANCE SHOWING AN AREA OF ABNORMALLY
DRY/LOW PW AIR SPREADING INTO CENTRAL PA.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
THE MAIN FORECAST ISSUE AND ULTIMATE SOURCE OF UNCERTAINTY
RESIDES WITH THE ENERGY ASSOCD WITH THE UPPER LOW NEAR THE CA
COAST WHICH IS STILL PROGGED TO REACH THE N-CENTRAL PLAINS ON
SATURDAY. THIS FEATURE WILL LKLY OFFER THE BEST OPPORTUNITY FOR
RAINFALL DURING THE PERIOD...MOST LKLY IN THE SUN-TUE TIMEFRAME.
HOWEVER MEANINGFUL SHORTWAVE DETAIL DIFFERENCES...NOT ONLY WITH
THIS ENERGY BUT WITH ONE OR TWO LEAD CONVECTIVE IMPULSES
DIMINISHED THE ABILITY FOR ADEQUATE TIMING THROUGH THE MID AND
LONG TERM.

AS WITH THE MOST RECENT SYSTEM...EXPECT DEWPOINTS TO CREEP BACK UP
THE 70 RANGE BY THE MON-TUE TIMEFRAME WITH THE PRECIPITATION
CHANCES. ESPECIALLY OVER THE CENTRAL AND SOUTH.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
WARM FRONT CURRENTLY DRAPED OVER CENTRAL PENNSYLVANIA THIS
MORNING LIFTING NORTHWARD IN RESPONSE TO APPROACHING WAVE OVER
OHIO. ALTHOUGH PLENTY OF LOW LEVEL MOISTURE IN PLACE ACROSS MUCH
OF CENTRAL AND NORTHERN SECTIONS THIS MORNING...A SLIGHT SOUTHWEST
SURFACE WIND HAS MADE SIGNIFICANT INROADS INTO THE IFR/LIFR AND
MVFR CONDITIONS THAT WERE ACROSS THE REGION FOR MUCH OF THE
OVERNIGHT.

APPROACHING WAVE MOVING IN WILL CONTINUE TO LIFT THE WARM FRONT
NORTHWARD DURING THE DAY. MODELS INDICATE THAT THE LOW CENTER WILL
MOVE ACROSS NORTHERN PA/SOUTHERN NY...WHERE THE BULK OF THE
STEADIEST AND HEAVIEST PRECIPITATION IS EXPECTED TO FALL. AS THE
LOW MOVES TO THE EAST...IT WILL DRAG A COLD FRONT ACROSS THE
REGION. THIS COULD TRIGGER SCATTERED TO BROKEN TSRA DURING THE
AFTERNOON INTO THE EARLY EVENING. THERE IS THE POTENTIAL FOR SOME
STORMS TO REACH SEVERE LIMITS.

CIG AND VSBY RESTRICTIONS WILL BE SOMEWHAT SCATTERED THIS
MORNING...AND BREIFLY LIFT BEFORE MORE MORE WIDESPREAD SHOWERS
AND THUNDERSORMS MOVE IN DURING THE AFTERNOON. LOWERING CONDITIONS
EXPECTED AGAIN TONIGHT IN THE POST FRONTAL AIRMASS...BUT DRYING
WILL BRING IMPROVING CONDITIONS FOR FRIDAY INTO SATURDAY AS VFR
WILL DOMINATE.

OUTLOOK...

FRI-SAT...PRIMARILY VFR. SUN...PRIMARILY VFR. ISOLATED TSRA
POSSIBLE WEST. SUN NIGHT- MON...RESTRICTIONS POSSIBLE IN SCATTERED
SHRA/TSRA.
