LA CORTE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
618 PM EDT MON JUL 14 2014

.SYNOPSIS...

A STRONG UPPER LEVEL TROUGH WILL SLIDE ACROSS SOUTHERN ONTARIO
AND QUEBEC THROUGH MIDWEEK. A COLD FRONT WILL PUSH SLOWLY ACROSS
THE COMMONWEALTH DURING THE DAY TUESDAY BRINGING COOLER AND DRIER
AIR THAT WILL REMAIN OVER THE REGION THROUGH THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...

HAVE STARTED TO TRIM BACK THE SEVERE THUNDERSTORM WATCH AS THE
ATMOSPHERE IS PRETTY WORKED OVER AND THE THREAT SEEMS TO BE MORE
FOR LOCALLY HEAVY RAIN THAN FOR DAMAGING WINDS.

FROM EARLIER...

SOUPY AIR SITUATED OVER THE CWA...WITH EXTENSIVE/MULTI-LAYER
CLOUDS AND SHOWERS. THIS CLOUD COVER WILL ALLOW ONLY MINIMAL
HEATING AND MIXED LAYER INSTABILITY FOR MUCH OF CENTRAL AND NWRN
PENN THROUGH DUSK /WITH CAPES ONLY ABOUT 500-1000 J/KG/.

ISOLATED LOW-TOPPED SUPERCELLS ARE DEVELOPING/SLOWLY DEEPENING
ACROSS THE LOWER SUSQ VALLEY AND SCENT PENN. THE VERY MOIST LLVLS
/WITH PWATS AOB 2 INCHES/ AND BREAKS IN THE CLOUD COVER ACROSS
SCENT AND SERN PENN WILL ALLOW SFC BASED CAPES TO CONTINUE RAMP UP
TO THE 2000-3000 J/KG RANGE ACROSS SCENT PENN AND THE LOWER SUSQ
VALLEY LATE THIS AFTERNOON.

THE COLLOCATION OF THIS INSTABILITY WITH A BELT OF MDTLY STRONG
SWRLY 850 MB WINDS OF NEARLY 30 KTS WILL LEAD TO AN AREA OF EHI/S
OF UP TO 2.5 M2/S2 LIFTING NE ACROSS THE SERN ZONES LATE THIS
AFTERNOON AND EARLY THIS EVENING.

ALTHOUGH THE MAIN SVR THREAT THROUGH EARLY THIS EVENING WILL BE
HEAVY RAIN AND ISOLATED MINI BOW ECHOES WITH STRONG STRAIGHT LINE
WIND GUSTS /MAINLY SE OF A JST/UNV/IPT LINE/...SCATTERED
SUPERCELLS WILL CONTINUE TO DEVELOP/ADVECT ENE ACROSS OUR SERN
ZONES WITH ONE OR TWO BRIEF TORNADOES POSSIBLE. LIFTING
CONDENSATION LEVELS TODAY WILL BE WELL UNDER 1 KM AGL IN MOST
PLACES AND FAVORABLE FOR MOIST RFDS.

TEMPS FOR THE REMAINDER OF THIS AFTERNOON WILL BE VARY FROM THE
LOWER TO MID 70S ACROSS THE CENTRAL AND NW ZONES...TO THE LOWER
AND MID 80S ACROSS THE LOWER SUSQ VALLEY.

THE REAL...STRONGER COLD FRONT IS DRAPED FROM NEAR CYYZ TO KORD
THIS BOUNDARY WILL START TO NUDGE INTO THE STATE LATER THIS
EVENING. PRIOR TO THAT THE MEAN LLVL SWRLY FLOW AND INLAND
PENETRATION OF THE LAKE ERIE BREEZE WILL HELP TO FIRE OFF ANOTHER
BAND OR TWO OF SHOWERS/STORMS ACROSS THE NW MTNS.

MOST OF THE STRONGER TSRA ACROSS THE LOWER SUSQ VALLEY WILL BE
PUSHING OFF TO THE EAST BY AROUND 8 PM EDT...BUT WEAKENING
VERSIONS WITH LOCALLY EXCESSIVE RAINFALL MAY LINGER THROUGH 9-10
PM.

SCT SHRA WILL THEN POSSIBLE THROUGH THE NIGHT DUE TO THE HUMID
AIR AND POSSIBILITY OF SEVERAL WEAK LLVL BOUNDARIES LEFT UNDER
NEUTRAL TO NEGATIVE FORCING. WILL DECREASE POPS TONIGHT TO AROUND
30 PCT.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
MODELS ARE IN DECENT AGREEMENT ON THE DOMINANT UPPER TROUGH AND
ITS TRACK DURING THE DAY TUESDAY. THE UPPER TROUGH DOES CUT OFF
AND DEEPEN TO 555 DAM...AND BECOMES CENTERED OVER SAGINAW BAY BY
18Z TUESDAY.

THE ASSOCIATED COLD FRONT WILL GRADUALLY PUSH EAST ACROSS THE
REGION TUESDAY. EXPECT NUMEROUS SHOWERS/SCT STORMS DURING THE
DAY...BUT BY FAR THE GREATEST CONCENTRATION OF CONVECTION AND
POTENTIAL FOR ANOTHER BOUT OF HEAVY RAIN WILL BE OVER OUR FAR
EASTERN ZONES.

WILL FOLLOW CONTINUITY WITH LIKELY POPS FOR THE ENTIRE
DAYTIME PERIOD TUESDAY...ESP IN THE EAST. THE STORMS SHOULD PUSH
TO THE EAST OF THE CWA AROUND SUNSET TUES. SEE HYDRO SECTION FOR
MORE. AFTER A MILD...MUGGY START TO THE DAY...HIGH TEMPS TUESDAY
WILL BE EVEN COOLER THAN TODAY. LOCATIONS ACROSS THE NRN MTS MIGHT
NOT CLIMB OUT OF THE 60S....WHILE THE CENTRAL AND SE ZONES SEE
MAXES ABOUT 3-5F BELOW NORMAL.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
MODELS ARE NOW IN FAIR AGREEMENT ON THE PLACEMENT AND MOVEMENT OF
THE UPPER LEVEL LOW THAT WILL DOMINATE THE WEATHER PATTERN THROUGH
THE REST OF THE WEEK. ANOTHER WAVE OF MOIST SOUTHWESTERLY FLOW
WILL EXIT THE REGION LATE TUESDAY EVENING. WITH DRY...COOLER
NORTHWESTERLY FLOW ADVECTING IN BEHIND THE FRONT. THE TROUGH WILL
LIFT TO THE NORTHEAST THROUGH THURSDAY. THOUGH THERE IS SOME UPPER
LEVEL CONVERGENCE THE LACK OF MOISTURE SHOULD LIMIT ANY
CONVECTION...OUTSIDE OF PERHAPS SOME ISOLATED SHOWERS IN THE
UPSLOPE REGIONS. THE COLD FRONT SHOULD BRING IN COOL TO AT LEAST
4-6F BELOW NORMAL DAYTIME HIGHS WEDNESDAY THROUGH THURSDAY. TEMPS
WILL LIKELY REBOUND TO NEAR NORMAL LATE THIS WEEK AND THROUGH THE
WEEKEND.

BOTH THE GFS AND ECMWF HAVE AN UPPER LEVEL TROUGH DEEPEN OVER THE
OHIO RIVER VALLEY...AND BRINGING SOUTHWESTERLY MOISTURE BACK INTO
THE REGION. THIS SHOULD BRING ANOTHER CHANCE FOR PRECIPITATION TO
CENTRAL PA SATURDAY WITH SOME RESIDUAL SCATTERED CONVECTION
POSSIBLE ON SUNDAY. BY LATE THIS WEEKEND THE MODELS AND ENSEMBLES
DIVERGE ON A SOLUTION...ESPECIALLY ON STRENGTH AND TIMING OF
CONVECTION SUNDAY INTO MONDAY. HOWEVER THERE SHOULD BE ANOTHER
DRIER PERIOD EARLY NEXT WEEK.

&&

.AVIATION /22Z MONDAY THROUGH SATURDAY/...
THICKENING...MULTI-LAYERED CLOUD COVER WILL BE PRESENT ABOVE THE
STUBBORN AREAS OF LOWERED CIGS AND VSBYS PRESENT ACROSS THE
CENTRAL AND NRN MTNS OF PENN FOR THE REMAINDER OF TODAY WITH
MAINLY MVFR CIGS AND PERIODS OF MVFR TO BRIEF IFR CONDITIONS.
WIDESPREAD SHOWERS AND SCATTERED COMPACT TSRA WILL OCCUR IN THIS
PART OF THE CWA.

FOR THE LOWER SUSQ VALLEY AND ADJACENT SCENT MTNS AND WRN
POCONOS...MUCH GREATER INSTABILITY AND LLVL WIND SHEAR WILL
SUPPORT THE DEVELOPMENT OF TALLER/STRONGER TSRA WITH BRIEF IFR IN
+TSRA. VERY ISOLATED STRONG WIND GUSTS ARE POSSIBLE BUT THE CHC OF
THESE WINDS IS TOO LOW AT ANY ONE LOCATION TO INCLUDE IN THE TAFS
FOR KMDT AND KLNS.

MORE LOWERED CIGS AND AREAS OF FOG EXPECTED FOR LATE TONIGHT AND
EARLY TUESDAY AFTER TODAY/S EXPECTED WIDESPREAD RAIN...AND PARTIAL
CLEARING WITH LIGHT WIND AND LINGERING HIGH SFC DEWPOINTS TONIGHT.

OUTLOOK...
TUES...TSTM IMPACTS POSSIBLE.

WED-FRI...MAINLY VFR.

SAT...SCATTERED SHOWERS AND POSS AFTERNOON TSRA WITH BRIEF
REDUCTIONS IN VSBY AND CIG.

&&

.HYDROLOGY...
MODEL MBE VECTORS TODAY IN THE SERN HALF OF THE AREA ARE FAIRLY
SHORT AS THE LLJET ASSOCIATED WITH THE OLD COMPLEX SLIDES IN FROM
THE WSW. THESE 35-40KT WINDS SLOW DOWN CONSIDERABLY TO THE NORTH
OF THE TURNPIKE...AND LIFT IS ANTICIPATED TO BE MAXIMIZED IN A
CORRIDOR FROM CBE-HGR-MDT-ABE. MULTIPLE/TRAINING CELLS COULD
PRODUCE VERY HEAVY RAIN WITH PWATS NEAR 2 INCHES. SOME OF THIS
AREA HAS RECEIVED TWO SHOTS OF HEAVY RAIN OVER THE PAST COUPLE OF
DAYS...AND THE GROUND IS VERY WET. THE MOST-RECENT HEAVY RAIN HAS
NOT YET BEEN ACCOUNTED FOR IN THE LATEST FLASH FLOOD GUIDANCE...SO
THE CURRENT GUIDANCE VALUES OF 2.5 TO 3 INCHES IN AN HOUR OVER THE
SE ARE MOST LIKELY TOO HIGH. THUS...HAVE ISSUED A FLASH FLOOD
WATCH FOR THE SERN THIRD OF THE REGION FOR TODAY/THIS EVENING.

THE MAIN FORCING MOVES TO THE EAST OF THE REGION THIS
EVENING...LEAVING A LULL IN THE HEAVY PRECIP TONIGHT AND EARLY
TUESDAY. ADDITIONAL STORMS ARE EXPECTED ON TUESDAY...BUT THE
COVERAGE AND INTENSITY MAY NOT BE QUITE AS HIGH AS TODAY.
THUS...HAVE LIMITED THE WATCH TO JUST TODAY. IF CONDITIONS
WARRANT...THE WATCH MAY BE EXTENDED INTO LATE TUESDAY OR AN
ADDITIONAL/SECOND WATCH MAY BE NECESSARY FOR TUESDAY.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH UNTIL 10 PM EDT THIS EVENING FOR PAZ036-

...HEAVY SHOWERS AND THUNDERSTORMS WITH INTENSE RAINFALL RATES
MAY PROMOTE LOCALIZED FLASH FLOODING CONCERNS THIS EVENING...

BANDS OF HEAVY SHOWERS AND THUNDERSTORMS WILL MOVE FROM SOUTHWEST
TO NORTHEAST ACROSS THE LOWER SUSQUEHANNA VALLEY THIS EVENING. THE
STORMS WILL BE CAPABLE OF PRODUCING VERY HIGH RAINFALL RATES ON
THE ORDER OF 2 TO 3 INCHES AN HOUR. THIS COUPLED WITH REPEATED
MOVEMENT OR TRAINING COULD PROMOTE EXCESSIVE RAINFALL AMOUNTS AND
LEAD TO LOCALIZED FLASH FLOODING. URBAN AND POOR DRAINAGE AREAS
ALONG WITH SMALL STREAMS AND CREEKS WILL BE THE MOST VULNERABLE
TO POTENTIAL FLOODING.

NEVER DRIVE YOUR VEHICLE INTO AREAS WHERE WATER COVERS THE
ROADWAY.
