AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 307 PM EDT SUN AUG 14 2005 .SHORT TERM (TONIGHT THROUGH WEDNESDAY)... MAIN CONCERN THIS EVENING WILL BE SEVERE THUNDERSTORMS ACROSS THE AREA...FOLLOWED BY A WELCOME BREAK IN THE HEAT AND HUMIDITY FOR MON THRU WED. SFC COLD FRONT STILL DRAPED ACROSS THE NY/PA BORDER AND HAS NOT MADE MUCH PROGRESS SOUTHWARD IN THE LAST 24 HRS. AS EXPECTED...T-STORMS HAVE DEVELOPED ALONG AND AHEAD OF THE BOUNDARY. WARM SECTOR ENCOMPASSES THE ENTIRE OF THE AREA...SO ALL OF CENTRAL PA UNDER THE GUN FOR SCT SEVERE STORMS LATE THIS AFTN AND THIS EVENING. LOOKING AT 18Z SPC SFC ANALYSIS...SFC BASED CAPE RANGING FROM 2000-3000 J/KG WITH 0-6 KM EFFECTIVE SHEAR APPROACHING 30 KTS. VERT WIND SHEAR PRETTY MUCH UNIDIRECTIONAL...BUT 35-40 KTS WILL SUPPORT ISOLATED SUPERCELLS. THE MAIN MODE SHOULD BE MULTICELL LINES/BOWS WITH DAMAGING WINDS THE MAIN THREAT. ACTIVITY SHOULD TAPER DOWN BY LATE THIS EVENING...AS FRONT SAGS SOUTHWARD AND INSTABILITY IS LOST. A MUCH MORE COMFORTABLE DAY IN STORE FOR MON...AS SFC HI PRES NOSES DOWN FROM THE GREAT LAKES INTO CENTRAL PA. LOWER TEMPS AND LOWER DEWPOINTS WILL FILTER IN FROM NORTH TO SOUTH. HIGH TEMPS WILL REACH REFRESHING UPPER 70S IN THE WEST/NW...WITH LOWER 80S CENTRAL AREAS AND MID 80S IN THE LOWER SUSQ. ETA BUFKIT PROFILES SHOW MID LEVEL CAP DEVELOPING DURING THE DAY...SO CHANCES OF CONVECTION ARE LIMITED. A POP-UP SHOWER CANNOT BE RULED OUT ACROSS THE SOUTH. THE FRONT THAT WILL PASS THRU TONIGHT WILL NOT LINGER TOO FAR TO OUR SOUTH...AND WILL BEGIN TO RETREAT BACK NORTH LATE MON NIGHT INTO TUE. INCR LOW LEVEL MOISTURE AND CLOUDS WILL CREEP BACK INTO THE PICTURE FOR FOR TUE/TUE NIGHT MAINLY ACROSS SOUTHERN AREAS. GFS A BIT MORE AGGRESSIVE WITH MOVING THE FRONT NORTH...WITH NAM ALMOST COMPLETELY DRY. WILL GO WITH A COMPROMISE AT THIS POINT...KEEPING THE NORTHERN HALF OF THE CWA DRY...WITH CHANCE (30-40%) POPS ACROSS THE SOUTHERN HALF. WILL LEAVE OUT MENTION OF THUNDER FOR NOW...AS INSTABILITY LOOKS TO BE LIMITED BY CLOUDS AND NORTHERLY FLOW. TEMPS WILL BE QUITE PLEASANT ONCE AGAIN AND MAY EVEN BE SLIGHTLY BELOW AVERAGE ACROSS THE SOUTH (NEAR 80). NAM/GFS IN GOOD AGREEMENT FOR WED...WITH NW FLOW ALOFT AND EVEN DRIER AIR ADVECTING IN FROM THE NORTH ASSOC WITH SFC HI PRES DIVING SOUTH OUT OF ONTARIO. && .LONG TERM (WEDNESDAY NIGHT THROUGH SUNDAY)... IN JUST ONE DAY...FORECAST HAS SUBSTANTIALLY CHANGED FOR LATE THIS WEEK INTO NEXT WEEKEND. IT WAS PREVIOUSLY THOUGHT THAT A COLD FRONT WOULD SWEEP THRU THE REGION FRI...HOWEVER LATEST MREF DATA SUGGESTS CFROPA COULD BE AS LATE AS SUN. +1-2 STDEV PWAT ANOMALIES HANG ON FROM FRI INTO SUN. WITH THE DELAYED FRONTAL PASSAGE...IT LOOKS LIKE THUR WILL BE DRY...WITH A CHANCE OF CONVECTION FRI/SAT AS SOUPY AIRMASS RETURNS. FRONT MAY EVEN STALL SOMEWHERE CLOSE TO CENTRAL PA...AS MEAN RIDGE STILL REMAINS IN THE SE CONUS AND THUS WILL BE DIFFICULT TO GET FRONT TO PUSH TOO FAR SOUTH OF PA. THIS ALL ADDS UP TO A HIGHLY UNCERTAIN FORECAST FROM DAYS 5-7. && .AVIATION... INCREASING COVERAGE OF SHOWERS AND THUNDERSTORMS WILL PEAK BETWEEN 21Z AND 00Z WITH LOCALLY IFR CIGS...VSBYS AND STRONG CONVECTIVE DOWNBURST GUSTS/LLWS FROM THE MORE INTENSE TSRA. OTHERWISE...EXPECT GENERALLY VFR CLOUD CEILINGS WITH AREAS OF MVFR VSBYS AND CIGS IN SHOWERS THROUGH THIS EVENING. FROM LATE EVENING ON...SFC COLD FRONT WILL SLIDE SOUTH OVER CENTRAL PENN. WIDESPREAD MVFR/LOCAL IFR CIGS IN POST FRONTAL STRATO CU WILL BLANKET THE HIGHER TERRAIN OF NORTHERN AND WESTERN PENN. CONDITIONS WILL IMPROVE TO MAINLY VFR CIGS AND VSBYS BY LATE MONDAY MORNING AS THE COLD FRONT MOVES SOUTH OF THE MASON DIXON LINE AND DRIER AIR GRADUALLY ADVECTS SOUTH OVER CENTRAL PENN. && .CTP WATCHES/WARNINGS/ADVISORIES...
