NWS State College, PA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 17, 2:40 PM EDT, 19 minutes earlier.
Area forecast discussion, Jul 17, 2:40 PM EDT, 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 240 PM EDT THU JUL 17 2008 .SYNOPSIS... HIGH PRESSURE...CENTERED OVER THE CENTRAL APPALACHIANS THIS AFTERNOON WILL DRIFT SLOWLY OFF THE EAST COAST OVER THE NEXT SEVERAL DAYS. A STATIONARY FRONTAL BOUNDARY DRAPED ACROSS SOUTHERN NEW YORK WILL INTERACT WITH THE VERY WARM AND HUMID AIRMASS TO PRODUCE SCATTERED LATE DAY AND EVENING THUNDERSTORMS TODAY...MAINLY ACROSS THE NORTHERN MOUNTAINS OF THE STATE AND THE MIDDLE SUSQUEHANNA VALLEY. A TROUGH OF LOW PRESSURE WILL APPROACH THE AREA FROM THE WEST LATE SUNDAY INTO EARLY NEXT WEEK BRINGING THE NEXT CHANCE FOR MORE WIDESPREAD SHOWERS AND THUNDERSTORMS. SLIGHTLY COOLER AIR WITH MUCH MORE COMFORTABLE HUMIDITY SHOULD FOLLOW FOR THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... SCATTERED TSRA (WITH ISOLATED STRONG TO SVR TSRA) AFFECTING MAINLY THE NCENT MTNS AND MIDDLE SUSQ VALLEY AT THE INTERSECTION OF A LLVL OUTFLOW BOUNDARY AND NOSE OF A WESTERLY 925-850 SPEED MAX OF 20-30KT. A BULLSEYE OF SURFACE BASED CAPE WAS ALSO COLLOCATED NEAR KIPT AND KSEG...WHICH WILL MAINTAIN (OR EVEN INCREASE) THE DEPTH/INTENSITY OF THE ELEVATED 60+ DBZ CORES IN THESE PULSE STORMS THROUGH 22-23Z ACROSS OUR ERN CWA. SLIGHTLY WARMING TEMPS/SUBSIDENCE ALOFT WILL LEAD TO NOTHING MORE THAN A BRIEF...STRAY SHOWER OR TSRA FROM THE SOUTH CENTRAL TO THE LOWER SUSQ VALLEY. KEPT POPS IN THIS AREA AOB 10 PERCENT. CLEARING SKIES AND DIMINISHING WIND WILL OCCUR AFTER 02Z. THIS WILL SET THE STAGE FOR A RATHER MUGGY NIGHT WITH MINS MAINLY IN THE MID 60S THROUGHOUT THE VALLEYS...AND AROUND 60F ACROSS THE HIGHER TERRAIN. && .SHORT TERM /FRIDAY/... QUASI-STATIONARY FRONTAL BOUNDARY LIFTS WELL NORTH OF THE REGION TONIGHT AND FRIDAY...AS SUBTROPICAL RIDGE BUILDS OVR THE NORTHEAST CONUS. ANY ISOLATED CONVECTION OVR THE NORTHERN TIER THIS EVENING SHOULD DIE OUT AS BLYR COOLS/STABILIZES. WARMER TEMPS ALOFT SHOULD PRECLUDE ANY PM CONVECTION ON FRIDAY. WILL KEEP POPS BLW 10 PCT BASED ON LATEST SREF DATA. PLENTY OF SUNSHINE...COMBINED WITH MEAN 850 TEMPS ARND 19C...SHOULD SUPPORT HIGHS FROM 90-95F OVER MOST OF THE AREA...WITH U80S ACROSS THE HIGH TERRAIN. && .LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/... NEXT SHORTWAVE TRACKING ACROSS SOUTHERN CANADA WILL PUSH A DYING COLD FRONT TOWARD PA LATE SATURDAY...WHICH COULD TOUCH OFF A LATE DAY TSTMS ACROSS THE NORTH. ENS QPF PLUME DATA SUGGESTS LITTLE CHC OF ANY PRECIP ACROSS CENTRAL AND SOUTHERN PA...WHERE HEAT SHOULD CONTINUE UNABATED. LATEST GEFS DATA SUGGESTS QUASISTATIONARY FNTL BNDRY WILL STAY TO THE NORTH OF PA THRU EARLY NEXT WEEK. THUS...ABV NORMAL TEMPS EXPECTED TO CONTINUE THRU THE MED RANGE OUTLOOK WITH A CHC OF DIURNAL CONVECTION EACH DAY. HPC MANUAL SFC PROGS SHOW A WAVE OF LOW PRES MOVG EWD THRU NY STATE ALONG THE AFOREMENTIONED Q-STNRY FNT SYS TUE-WED. GMOS/HPC BLEND CONTINUES TO YIELD CHC POPS THIS PD. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... ISOLATED TO SCATTERED MVFR CIGS AND VSBYS IN SHRA/TSRA WILL PREVAIL THROUGH DUSK ACROSS THE REGION NORTHEAST OF A LINE FROM KBFD AND KDUJ...TO KUNV AND KMDT. A FEW OF THE STORMS COULD BECOME STRONG ENOUGH TO PRODUCE BRIEF IFR CIGS/VSBYS WITH SFC WIND GUSTS TO 40 KTS INVOF KIPT AND KSEG...AND POINTS EAST. OTHERWISE...HIGH PRESSURE CENTER JUST TO THE SOUTH OF PENN WILL DRIFT VERY SLOWLY TO THE EAST THROUGH FRIDAY AND SLIP OFFSHORE THIS WEEKEND. SERIES OF WAVES WILL SLIDE W-E ACROSS NEW YORK AND NEW ENGLAND AS FRONTAL BOUNDARY REMAINS STATIONARY JUST TO OUR NORTH. PATCHY 3-5SM GROUND FOG WILL FORM ONCE AGAIN LATE TONIGHT THROUGH THE MID MORNING HOURS FRIDAY AS WINDS DROP OFF TO LIGHT AND VARIABLE. MAINLY LIGHT...SOUTHWEST TO WEST WINDS WILL PREVAIL FOR THE NEXT SEVERAL DAYS. BEST CHC FOR SHRA/TSRA WILL BE DURING THE LATE WEEKEND THROUGH MONDAY AS A FRONTAL BNDRY SLIPS ACROSS THE MID-ATLANTIC REGION.
