Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Washington/Dulle, VA (KIAD), launched 12:00Z, 9.6 hours before the alert went out and 142 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jun 9, 3:35 PM EDT, 2 hours 1 minute earlier.
Area forecast discussion, Jun 9, 3:35 PM EDT, 2 hours 1 minute before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 335 PM EDT THU JUN 9 2005 .SHORT TERM (TONIGHT THROUGH FRIDAY)... FOR THE FIRST TIME THIS SEASON THE BERMUDA RIDGE IS EXERTING THE MAJOR INFLUENCE OVER THE EASTERN AND NORTHEASTERN US. PWATS ARE RUNNING 130-180 PERCENT OF NORMAL AND THE CAP IS WEAK TO NON EXISTENT. EVEN WITHOUT ABUNDANT SUNSHINE...ACTIVITY IS BREAKING OUT IN EARNEST OVER THE SOUTHERN HALF OF THE REGION. POTENTIAL WILL BE THERE FOR LOCALIZED GULLY WASHERS AS CELLS SEEM DESTINED TO BE VERY SLOW MOVING. ETA AND GFS BOTH SHOW A DEVELOPING SOUTHERLY LLJ FOR THE AFTERNOON AND EVENING...IN THE 15-25KT RANGE. NOT EXCITING BY COLD SEASON STANDARDS...BUT WITH MOISTURE AND INSTABILITY...ANOMALY PAGES RANK IT IN THE 1-3 STD DEV ABOVE NORMAL RANGE. THIS COMBINED WITH WEAKLY DIFFLUENT THICKNESSES MAY PROVIDE THE INGRED NECESSARY FOR BACK BUILDING CELLS...POSSIBLY INCREASING THE FLASH FLOOD THREAT. COULD BE A VERY BUSY EVENING. ACTUALLY BACKED POPS OFF JUST A HAIR FOR FRIDAY AS INDICATIONS ARE WE COULD BE A BIT MORE CAPPED. THE WEAK SHORTWAVE IN THE FLOW TODAY GETS REPLACED BY STRONG ANTICYCLONIC FLOW WITH HEIGHT RISES OF 10- 30M ON AVERAGE. MID LEVEL TEMPS...AROUND 700 MB...ARE FCST TO RISE TO AROUND 8C...VERY NEAR OUR LOCAL CAP VALUES. SO DESPITE WHAT WILL STILL BE A VERY WARM AND HUMID AIRMASS...THE HOPE IS THAT NOT AS MUCH CONVECTION WILL MANAGE TO POP THRU THE LID. LA CORTE && .LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)... WE REMAIN UNDER ANOMALOUSLY HIGH HGHTS AND A GREAT SURGE OF PWATS CONNECTED DIRECTLY TO THE DEEP TROPICS WELL INTO THE WEEKEND AND THROUGH AT LEAST MON OR EARLY TUESDAY. ANOMALY PAGES SHOW PWAT AS HIGH AS 1-3 STD DEV ABOVE NORMAL THROUGHOUT THE PERIOD. THIS SHOULD ASSURE A CONTINUATION OF WARM HUMID SUMMERY CONDITIONS THROUGH THE WEEKEND WITH THE EVER PRESENT CHANCE OF MAINLY DIURNAL CONVECTION. A POSSIBLE COMPLICATION IS THE EMERGENCE OF ARLENE WHICH IS FCST TO HIT THE GULF COAST SOMETIME SATURDAY MORNING. AFTER LANDFALL...THE GFS FORECAST FOR THE SFC SYSTEM STARTS TO DIVERGE SIGNIFICANTLY FROM THE NHC FCST. THE GFS TAKES IT UP CLOSER TO THE MIDWEST BEFORE WASHING IT OUT...AND NOT INTO THE OHIO VALLEY WHICH SEEMS TO MAKE MORE SENSE GIVEN THE FLOW. THE CANADIAN MODEL WANTS TO TAKE THE REMNANTS INTO THE ERN GR LAKES WHILE THE NOGAPS IS SOMEWHERE IN BETWEEN. IT COMES DOWN TO THE POTENTIAL FOR SOME VERY HEAVY RAINS LOCALLY SHUD THE REMNANTS WANDER OUR WAY. THE MREF FCSTS FOR THE PWATS SHOW THE CONTINUED PLUME OF ANOMALOUSLY HIGH MOISTURE CONTINUING TO FEED NORTHWARD ALL THE WAY FROM THE SAME DEEP TROPICAL AIR MASS ARLENE IS CURRENTLY THRASHING AROUND IN. LA CORTE && .AVIATION... LOTS OF CONVECTION (AND CB/S) SCATTERED ABOUT THE REGION...BUT AS OF 18Z...AREA VCNTY OF KBFD IS STAYING SUPPRESSED WITH ONLY FLAT CU. DO NOT EXPECT THIS TO CONTINUE AS THE SUN IS MAKING AN APPEARANCE IN THE NORTH COUNTRY...AND WILL CARRY VCTS W/TEMPO TSRA MOST LOCATIONS THRU 01/02Z. WILL ALSO LEAVE SHOWERS IN FOR KIPT FOR LONGER (08Z)...AS THE LLJET SHOULD HELP TO CONTINUE SOME NOCTURNAL CONVECTION (ESP IN THE NE)...EVEN WITHOUT MUCH OF A TRIGGER. MINOR WORRY FOR SOME LOWER CLOUDS (MVFR) THIS EVENING AFTER SHOWERS DIE OFF...BUT THEN WORRY SHIFTS TO FOG. WITH NO WIND AND HIGH DWPTS/LLVL MOISTURE...THINK MANY LOCATIONS WILL BE LOCALLY DENSE...BUT WILL MAKE KIPT WORSE THAN EVERYONE ELSE (LIFR AROUND SUNRISE). NO BIG REASONS TO THINK PERSISTENCE WILL NOT HOLD...AND WOULD PUT SCT AFTN CONVECTION IN AGAIN...BUT THAT IS TOO FAR OUT FOR THIS PKG. DANGELO && .CTP WATCHES/WARNINGS/ADVISORIES... PA...NONE. &&
