AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
1113 AM EDT THU SEP 12 2013

.SYNOPSIS...
THE UNSEASONABLY WARM AND HUMID CONDITIONS OF THE PAST FEW DAYS
WILL END LATER TODAY AS A STRONG COLD FRONT CROSSES THE REGION.
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WILL OCCUR THROUGH
LATE THIS AFTERNOON...AND SOME MAY PRODUCE STRONG TO LOCALLY
DAMAGING WIND GUSTS AND HAIL. ANOTHER TASTE OF FALL WILL ARRIVE IN
THE WAKE OF THIS FRONT. BELOW NORMAL TEMPERATURES ARE EXPECTED
FROM FRIDAY INTO THE UPCOMING WEEKEND.

&&

.NEAR TERM /UNTIL 9 PM THIS EVENING/...
80S IN THE SC MTS SHOULD CONTINUE TO HEAT UP AS THE SKY HAS
CLEARED NICELY. EARLY CONVECTION IS NOW ALMOST OUT OF LANCASTER
COUNTY. THE HEATING SHOULD PUMP THE CAPES UP TO LEVELS JUST SHY OF
WED NUMBERS - BUT STILL WELL ABOVE 1500J/KG. FIRST COLD FRONT
WITH WIND SHIFT AND SLIGHT DIP IN DEW POINTS IS NOW ALMOST TO LAKE
ERIE...BUT PRECIP OUT AHEAD OF THE FRONT ALONG A MOISTURE BOUNDARY
WILL CONTINUE TO SLIDE EAST AND TINY CELLS ALREADY DEVELOPING IN
A PSEUDO-LINE JUST EAST OF THAT SHIELD OF RAIN. THESE CELLS ARE
ROUGHLY IN LINE WITH THE CONVECTION IN OH AND SHOULD CONGEAL INTO
A BIGGER AND MORE-COHERENT LINE OF STORMS SHORTLY. HRRR AND RUC
ARE IN AGREEMENT WITH THE GOING FCST ON TIMING. THEY DO INDICATE A
SECONDARY LINE -JUST BEHIND THE FIRST BY 30-60 MINS...BUT THIS IS
WAY TOO CUTE TO TRY AND PAINT IN 1 HR POP GRIDS. SO...WILL HOLD
THE LINE WITH THAT AND JUST KNOCK THE POPS A LITTLE HIGHER OVERALL
WITH HIGHER CONFIDENCE NOW VS EARLIER. SEVERITY OF THE STORMS IS
STILL LIKELY. SLIGHT RISK WAS EXPANDED EARLIER BY SPC - PROBABLY
WITH AN EYE TO TIMING AND CLEARING THAT IS OCCURRING. THE STORMS
SHOULD BE THROUGH IPT/UNV/AOO BEFORE SUNSET...AND OUT OF MDT/LNS
BY 9 PM. SOME SHOWERS MAY LINGER ALONG THE FAR EAST AND FAR SRN
TIER THRU MIDNIGHT...BUT THESE SHOULD BE WELL BEHIND THE BEST
MOISTURE AND HEATING.

&&

.SHORT TERM /9 PM THIS EVENING THROUGH 6 PM FRIDAY/...
5H TROF AXIS SWINGS ACROSS THE CENTRAL AND ERN GLAKS TONIGHT AND
SHARPENS AND SLOWS WHILE TRAVERSING CENTRAL PA ON FRIDAY AFTERNOON.
STRONG COLD ADVECTION AND MUCH DRIER AIR MASS REACHES INTO WESTERN
AND CENTRAL AREAS DURING THE AFTERNOON. SHOWERS WILL STILL BE
POSSIBLE IN THE TYPICAL NORTHWEST FLOW REGIME (FROM THE LAURELS
THROUGH THE NORTHWEST MOUNTAINS AND NORTHERN TIER COUNTIES)...BUT
QPF WILL BE LIGHT. AS PREVIOUSLY ADVERTISED...HIGHS ON FRIDAY WILL
STRUGGLE TO REACH THE MID TO UPPER 50S ACROSS THE NORTHWEST...
WITH LOWER TO MIDDLE 60S COMMON FOR HIGHS FROM THE CENTRAL
MOUNTAINS TO THE MIDDLE SUSQ RIVER VALLEY. THE SOUTH CENTRAL
MOUNTAINS AND LOWER SUSQ SHOULD SEE MAXES NEAR OR SLIGHTLY ABOVE
70F FRIDAY AFTERNOON...A FAR CRY FROM THE LOWER 90S SEEN TUESDAY
AND WEDNESDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
THE MAIN STORY OF THE EXTENDED IS A RETURN TO AUTUMN AS TEMPERATURES
DROP BACK TO WELL BELOW NORMAL LEVELS. EXPECTING A MUCH COOLER
WEEKEND WITH TEMPERATURES FROM THE MID 60S ON SATURDAY...TO LOW
70S ON SUNDAY.

A WEAK SHORTWAVE IS PROGGED TO DROP THROUGH THE UPPER FLOW SOMETIME
MONDAY BRINGING ANOTHER FRONT. THE WEAKNESS OF THE SYSTEM AND THE
DRYNESS OF THE AIR IN PLACE BRINGING INTO QUESTION HOW MUCH PCPN MAY
ACCOMPANY THE FRONT...SO KEPT MINIMAL POPS ATTM. THE SECOND
ANTICYCLONE FOLLOWS TUE INTO WEDNESDAY FOR YET MORE DRY WEATHER.

&&

.AVIATION /15Z THURSDAY THROUGH MONDAY/...
ARRIVAL OF A POTENT COLD FRONT IN BFD SHOULD BE LATE THIS
AFTN...AND INTO THE SERN TERMINALS BY MIDNIGHT. HOWEVER...THE MAIN
TIMING OF STORMS SHOULD BE ABOUT 3-4 HRS AHEAD OF THIS TIME. THESE
STORMS ARE INTO BFD AND WILL EXIT THE LOWER SUSQ VALLEY ABOUT 00Z-
01Z. EXPECT THIS BOUNDARY TO BE CONVECTIVELY ACTIVE AND RELATIVELY
WELL-ORGANIZED AS IT CROSSES THE AIRSPACE...WITH THE POTENTIAL
FOR STRONG TO SEVERE TSTORM WIND GUSTS AND BRIEF IFR VSBY/CIG
REDUCTIONS.

COOLER AND DRIER AIR WILL BEGIN TO WORK IN BEHIND THE COLD FRONT
TONIGHT. HOWEVER...LINGERING LOW LEVEL MOISTURE FORCED TO ASCEND
THE ALLEGHENY MTNS WILL PROBABLY PRODUCE SOME IFR CIGS AT BFD AND
JST. SHORT BUT INTENSE CONVECTION IS POSSIBLE ON FRI - MAINLY IN
THE AFTN AS THE COLDEST AIR ALOFT CROSSES THE AREA. THE MOST
LIKELY TERMINALS WHICH MIGHT SEE SOME IMPACT WILL BE JST AND BFD.
WINDS WILL MOST LIKELY PICK UP AND GUST INTO THE 20-25KT RANGE IN
THE AFTN.

OUTLOOK...
SAT...NO SIG WX EXPECTED.
SUN...PATCHY AM FOG POSSIBLE...OTHERWISE VFR.
SUN PM-MON AM...ISOLD SHRA POSS.
MON PM...NO SIG WX EXPECTED.
