The episode as NWS CTP wrote it up.
Clusters of showers and isolated thunderstorms developed on the southwest periphery of broad cyclonic (counter-clockwise) flow aloft associated with a slow-moving upper low over New England. Despite limited instability, strong mid-level winds and steep lapse rates promoted wind damage within stronger line and bowing segments as they progressed from northwest to southeast across central Pennsylvania.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS State College, PA wrote its last area forecast discussion before the first event at Jun 3, 4:39 PM EST, 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 539 PM EDT SUN JUN 3 2012 .SYNOPSIS... AN UPPER LEVEL LOW PRESSURE AND ASSOCIATED SURFACE LOW SPINNING OVER GEORGIAN BAY THIS AFTERNOON...WILL MOVE SOUTHEAST ACROSS NEW YORK STATE AND PARK ITSELF OFF THE EAST COAST OVER THE NEXT FEW DAYS. THIS PATTERN WILL KEEP COOLER THAN NORMAL TEMPERATURES AND UNSETTLED CONDITIONS WITH DAILY CHANCES OF SHOWERS IN THE FORECAST THROUGH THE FIRST PART OF THE UPCOMING WEEK. A RIDGE OF HIGH PRESSURE ALOFT WILL BUILD IN FROM THE MIDWEST WITH CLEARING AND WARMER CONDITIONS LATE IN THE WEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... REGIONAL 88D LOOP HAS LIT UP WITH CLUSTERS OF SHOWERS AND MAINLY LOW-TOPPED TSRA OVER THE PAST 90 MINUTES. EXPECT THE CONVECTION TO STRENGTHEN A BIT MORE...WITH THE STORMS GROWING ANOTHER SEVERAL-10 KFT LATE THIS AFTERNOON AS SFC TEMPS WARM BY ANOTHER 3-5 DEG F ACROSS MUCH OF CENTRAL AND SOUTHERN PENN WHERE THINNER CLOUD COVER AND NUMEROUS BREAKS WERE OCCURRING. THE STRONGEST STORMS IN PENN ATTM WILL BE TRACKING ACROSS THE WRN AND SCENT MTNS THROUGH LATE THIS AFTERNOON...AND IMPACT THE LOWER AND MIDDLE SUSQ VALLEY AFTER 22Z. THE STEEPEST...850-500MB LAPSE RATES ON THE ORDER OF APPROX 7C/KM WILL BE SITUATED ACROSS THE SOUTHERN HALF OF THE STATE AND WILL COINCIDE WITH A CORE OF WNW 850-800 MB WINDS OF 40-45KT /AND TRACK OF THIS TSRA CLUSTER/ TO CREATE THE THREAT SOME HAIL AND GUSTY WINDS BETWEEN 40-45 KTS. SPC CONTINUES TO HIGHLIGHT OUR AREA IN THE DAY 1 SEVERE OUTLOOK AND RECENTLY ISSUED SWOMCD...BUT STILL NOTES THAT THE EXPECTED SMALL AREAL COVERAGE OF POTENTIAL SEVERE WEATHER PRECLUDES AN UPGRADE TO SLIGHT RISK. THIS AFTERNOONS MAX TEMPS BETWEEN 20-22Z WILL VARY FROM AROUND 60 DEGREES ACROSS THE FAR NW MTNS...TO THE MID 70S THROUGHOUT MUCH OF THE LOWER SUSQ VALLEY. THE SHOWERS WILL DIMINISH IN COVERAGE DURING THE EVENING. HOWEVER...ADDITIONAL FORCING WILL DEVELOP LATER TONIGHT AS THE UPPER LOW PASSES OVER THE WRN NY STATE AND NERN PA. THIS SHOULD KEEP THE SHOWERS GOING...BUT LACK OF SOLAR HEATING AND SFC INSTABILITY WILL CAUSE THE VERTICAL EXTENT AND INTENSITY OF THE CELLS TO DIMINISH AS WELL. WILL CONTINUE TO MENTION THUNDER INTO THE EARLY EVENING...THEN DIP POPS SLOWLY TO MAINLY SCATTERED SHOWERS THRU THE NIGHT. MINS WILL BE RIGHT AROUND NORMAL AS A RESULT OF THE LIGHT WEST WIND AND GENERALLY BKN CLOUD COVER...AT LEAST ACROSS THE CENTRAL AND NORTH. IF MORE CLEARING THAN ANTICIPATED OCCURS...TEMPS COULD DROP TO NEAR 40F IN THE NORTH. MINS EARLY MONDAY MORNING WILL RANGE FROM THE M40S NORTH...TO THE LOWER AND MID 50S IN THE SUSQ VALLEY. && .SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/... THE EXTENT OF THICKER CLOUD COVER MONDAY IS SOMEWHAT IN QUESTION...AS A SECOND AND RATHER POTENT SHORT WAVE DROPS SE FROM THE LOWER GREAT LAKES. WILL PAINT OUR SKY GRIDS WITH A CONSISTENT 75-95 PERCENT CLOUD COVER...ALLOWING FOR A LITTLE WIGGLE ROOM OF MOSTLY CLOUDY TO CLOUDY SKIES TO BE READ VIA OUR ZONE TEXT. TEMPS WILL LIKELY BE A FEW /TO SVRL DEG F BELOW SUNDAYS MAXES/ AS THE MEAN LLVL FLOW VEERS BY 30-40 DEG - TO THE NW...AND MODERATELY STG COLD ADVECTION OCCURS IN THE 925-850 MB LAYER. MAXES COULD EASILY HOLD IN THE UPPER 50S ACROSS THE HIGHEST TERRAIN OF THE FAR NORTH...AND REACH THE UPPER 60S TO AROUND 70F IN THE SOUTHERN VALLEYS. THE BEST CHC FOR SHOWERS /AND PERHAPS SOME MORE LOW-TOPPED TSRA/ WILL BE ACROSS THE NE THIRD OF THE CWA. POPS WILL BE MAINLY IN THE CHC CATEGORY FOR THE SW HALF OF THE FCST AREA. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... UPPER LOW CENTERED OFF COAST OF NEW ENGLAND MON NIGHT WILL DRIFT TO THE CANADIAN MARITIMES THROUGH FRI...BUT ACCOMPANYING LARGE TROUGH WILL KEEP COOL NW FLOW ACROSS PENNSYLVANIA THROUGH MUCH OF THE WEEK. TUE WILL AGAIN SEE SCT SHOWERS/ISOLATED TSTMS DEVELOP DURING THE AFTERNOON HOURS...BUT THESE WILL BE LESS IN COVERAGE THAN MONDAY. TEMPS WILL BE SIMILAR. ON WED...SHOWER CHANCES CONTINUE TO SLOWLY DROP...BUT ISOLD/SCT SHOWERS STILL EXPECTED TO DEVELOP WITH COOLER AIR ALOFT AND DAYTIME HEATING. TEMPS BEGIN TO SLOWLY RECOVER...BUT REMAIN 5-7F BELOW NORMAL. EVEN KEPT MENTION OF A SHOWER INTO THU AS BACK EDGE OF TROUGH /AND ACCOMPANYING WEAK SHORTWAVE/ PUSH THROUGH. TEMPS REMAIN SLIGHTLY BELOW NORMAL. HIGH PRESSURE FINALLY BUILDS IN FROM THE WEST BY FRI AND CONTINUES THROUGH THE WEEKEND. MORNINGS WILL BE CHILLY...BUT AFTERNOON HIGHS FRI WILL BE NEAR NORMAL WITH ABOVE NORMAL TEMPERATURES RETURNING FOR SAT/SUN. && .AVIATION /22Z SUNDAY THROUGH FRIDAY/... SEVERAL BROKEN LINES OF CONVECTION PUSHING THROUGH THE REGION LATE THIS AFTERNOON. ALTHOUGH LIGHTNING ACTIVITY LIMITED...STORMS MIXING DOWN SOME HEALTHY WINDS IN THE 35 TO 45 KNOT RANGE. THESE STORMS WILL AFFECT KAOO/KJST...AS WELL AS LOWER SUSQUEHANNA AIRPORTS FOR THE NEXT SEVERAL HOURS. SEVERAL ADDITIONAL CLUSTERS OF STRONGER SHOWERS AND TSRA APPROACHING THE NORTHWEST. EXPECT OVERALL COVERAGE AND INTENSITY TO DIMINISH AFTER 01Z. RELATIVELY BRIEF PERIODS OF MVFR CIGS ARE LIKELY...WITH MAINLY VFR CONDS PREVAILING ACROSS MOST OF THE REGION THROUGH 04Z MONDAY. INCREASINGLY MOIST UPSLOPE FLOW WILL LIKELY LOWER CIGS TO IFR AT KBFD AND KJST LATE TONIGHT THROUGH THE MID MORNING MONDAY...THEN PERIODS OF MVFR CIGS IN ALL AREAS MONDAY WITH SCATTERED SHOWERS AND ISOLATED AFTERNOON TSRA.
