NWS State College, PA wrote its last area forecast discussion before the first event at May 14, 1:36 PM EST, 4 hours 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 236 PM EDT SAT MAY 14 2005 .SHORT TERM (TONIGHT THROUGH SUNDAY)... A FEW SHOWERS SHOWING UP ON RADAR THIS AFTERNOON BUT CERTAINLY NOTHING SIGNIFICANT AT THIS POINT. MUCH LARGER BATCH OF SHOWERS AND THUNDERSTORMS TO THE WEST OVER OHIO VALLEY ASSOCIATED WITH COLD FRONT MOVING EASTWARD. THIS IS THE MAIN CONCERN FOR THIS AFTERNOON AND EVENING AS ATMOSPHERE CONTINUES TO DESTABILIZE. DEW POINTS HAVE RISEN TO THE UPPER 50S OVER A GOOD PORTION OF THE CWA AND TEMPS IN THE 70S IN SOME AREAS. STILL REMAIN UNDER A SLIGHT RISK THIS AFTERNOON WITH APPROACHING CONVECTION. HOWEVER THE MAIN THREAT REMAINS SOUTH OF PA ASSOCIATED WITH HIGHEST CAPE VALUES OVER SOUTHERN OHIO...KENTUCKY...AND WEST VIRGINIA. NO CREDIBLE AMOUNT OF DIRECTIONAL SHEAR TO TALK ABOUT...BUT SPEED SHEAR IS SOMEWHAT IMPRESSIVE WITH WINDS JUST ABOVE 4000 FT AT 30-45 KTS. ON SUNDAY...SHOWERS ARE STILL POSSIBLE AS SYSTEM TO OUR NORTH WORKS THROUGH THE AREA...HOWEVER WITH MAIN THUNDERSTORM DYNAMICS WELL OUT OF THE AREA DO NOT EXPECT ANY THUNDER ONLY SCATTERED SHOWERS. AS MID SHIFT SO EXPERTLY CONVEYED (SEE PREVIOUS DISCUSSION FOR FULL EXPLANATION)...POTENTIAL FOR A STRONGER THERMALLY DIRECT TRANSVERSE CIRCULATION TO DEVELOP AND THIS COULD MEAN MORE THAN JUST SHOWERS FOR PARTS OF PA. && .LONG TERM (SUNDAY NIGHT THROUGH SATURDAY)... HIGH PRESSURE MOVES INTO THE AREA SUNDAY NIGHT AND INTO MONDAY MORNING. THIS BRINGS LOWER THAN NORMAL TEMPS INTO PA THROUGH THE WORK WEEK. NO REAL CHANCE FOR PRECIP UNTIL NEXT SYSTEM APPROACHES PA ON WED AFTERNOON AND EVENING. CHANCE FOR PRECIP LINGERS EACH DAY THOUGH THE REMAINDER OF THE FORECAST PERIOD. && .AVIATION... TOUGH FORECAST FOR AVIATION INTERESTS TODAY THROUGH TOMORROW. CENTRAL PA CURRENTLY SITTING IN WARM SECTOR AWAITING DEVELOPMENT OF SHOWERS/TSTORMS FOR LATE THIS AFTERNOON INTO THIS EVENING. TSTORMS EXPECTED TO BE MULTICELLULAR AS A BROKEN LINE OF CONVECTION FORMS AND SLIDES EAST ACROSS THE SOUTHERN TIER. THESE STORMS WILL POTENTIALLY BECOME STRONG AND CAPABLE OF PRODUCING VERTICAL WIND SHEAR AND SURFACE GUSTS IN EXCESS OF 40 MPH. THIS ACTIVITY WILL DIE DOWN THIS EVENING...BUT SHOWERS AND WEAKER TSTORMS WILL CONTINUE TO BRING AREAS OF MVFR TO CENTRAL PA. AFTER MIDNIGHT TONIGHT A COLD FRONT WILL PUSH THROUGH ENDING CONVECTIVE THREAT BUT BRINGING A 6-12HR PERIOD OF WIDESPREAD MVFR (IFR IN THE NW MTNS) CONDITIONS BEFORE CEILINGS RISE ABOVE 3KFT BETWEEN 12-15Z. UPPER LOW SLIDES IN BEHIND FOR THE DAY ON SUN HOWEVER...BRINGING HIT AND MISS SHOWERS (AND MVFR CONDS) FROM LATE MORNING THROUGH THE AFTERNOON...WITH A TSTORM POSSIBLE FROM KIPT TO KMDT. THEN QUIETER WEATHER SETTLES IN FOR SUN NIGHT INTO MONDAY. && .CTP WATCHES/WARNINGS/ADVISORIES... PA...NONE. && SHORT TERM...ONDREJIK LONG TERM...ONDREJIK AVIATION...RXR
