CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 255 PM EDT SAT JUL 15 1995 REMAINS OF THE COLD FRONT EXTEND FROM CAPE COD WEST ACROSS CENTRAL PA TO NORTHERN OH AT 18Z. SATELLITE SHOWED SUPPRESSION OF THE CLOUDS ACROSS PA BEHIND THE BOUNDARY THAT ADVECTED OUT AHEAD OF THE EARLY MORNINGS CONVECTION...DESPITE THE INCREDIBLE INSTABILITY ON MORNING RAOB. THERE IS EVIDENCE THAT THE BOUNDARY MOVED SOUTH AND SOUTHWEST ACROSS THE STATE REACHING INTO OH THIS AFTERNOON. NVA QUITE EVIDENT ALOFT ACROSS WESTERN PA THIS AFTERNOON AND ALSO FAIR INDICATION OF ANTICYCLONIC TURNING IN THE CLOUD MOTION ON THE SATELLITE. THIS PROBABLY ACCOUNTS FOR THE LACK OF CONVECTION ACROSS THE AREA. THUNDERSTORMS HAVE EXPLODED OUT AHEAD OF THE UPPER SHORT WAVE THAT IS MOVING NORTHEAST FROM KENTUCKY INTO OH. THAT SAME UPPER WAVE IS PROGGED TO MOVE NORTHEAST AND SPREAD INTO WESTERN PA OVERNIGHT. BEST CHANCE FOR STRONG THUNDERSTORMS WILL BE AFT MIDNIGHT HERE IN CENTRAL PA. DOES APPEAR THAT WE/VE HIT THE PEAK OF THE HEAT WAVE AND AS THE SURFACE RIDGE BUILDS SOUTH OVERNIGHT THAT JUST A BIT LESS HEAT AND HUMIDITY WILL BE OVER MOST OF THE AREA. CONCUR WITH NEED TO KEEP THE AXDVISORY UP UNTIL THUNDERSTORMS MOVE IN TONIGHT. TED
