The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Buffalo Intl Airport, NY (KBUF), launched 00:00Z, 1.9 hours before the alert went out and 204 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.

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 May 2, 8:01 PM EDT, 1 hour 55 minutes earlier.
Area forecast discussion, May 2, 8:01 PM EDT, 1 hour 55 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 801 PM EDT WED MAY 2 2012 .SYNOPSIS... A WARM FRONT OVER THE CENTRAL COUNTIES WILL LIFT ONLY A LITTLE TO THE NORTH AND EAST TONIGHT. STORMS ARE EXPECTED IN THE WARMER AND MORE-MOIST AIR TO THE WEST AS AN UPPER-LEVEL DISTURBANCE MOVES DOWN FROM THE GREAT LAKES. MORE DISTURBANCES ALOFT WILL CONTINUE TO ROLL AROUND THE PERIPHERY OF A BUILDING UPPER RIDGE OVER THE SOUTHEASTERN STATES AND INTERACT WITH THE BOUNDARY...PRODUCING EPISODES OF SHOWERS AND THUNDERSTORMS THROUGH THE END OF THE WORK WEEK. && .NEAR TERM /THROUGH THURSDAY/... STORMS ARE FINALLY FIRING UP OVER NWRN PA/WRN NY WITH ADVANCE OF MID LEVEL COOLING. LAPSE RATES STILL STEEP AND CAPES >1000J/KG INVOF THAT CLUSTER OF CELLS. THESE CELLS IN ADVANCE OF ANOTHER BROKEN LINE OF CONV DO HAVE SOME HIGH EHI VALUES...SO MONITORING FOR CIRCULATION WARRANTED. HAVE GUSTY WINDS MENTIONE IN THE GRIDS/ZFP. ACTIVITY OVER SWRN SECTIONS HAS DIED WITH LOSS OF SUN/HEAT. BUT THE CONV TO THE NW IS PROGGED BY MOST MODELS TO CONTINUE IN AN ORDERLY FASHION INTO THE CENTRAL COS THROUGH 06Z AND DISSIPATE SOMEWHAT AFTER 06Z AS MOST OF THE CONVECTION DIPS INTO THE COOL/STABLE AIR TO THE EAST. AFTN DISC... FRONTAL BOUNDARY EXTENDING FROM LAKE ERIE ACROSS CENTRAL MTNS CONTINUES TO BECOME MORE ORIENTED IN A N-S DIRECTION. AT 18Z...FRONT LOCATED IN VICINITY OF KBFD-KUNV-KDCA. THE FNTL BNDRY/LLVL CONVERGENCE AXIS MAY ACT AS THE FOCUS TO TRIGGER SCT SHOWERS AND THUNDERSTORMS LATER TDY. SPC HAS OUTLINED THE SW 1/2 OF THE CWA IN THE DAY 1 SLGT RISK...WHICH SEEMS WARRANTED GIVEN LARGE AREA OF INSTABILITY AND MOISTURE. TEMPS TO THE EAST OF THE BOUNDARY WILL BE SEVERAL DEGS COOLER THAN LOCATIONS FURTHER TO THE WEST...OWING TO SFC RIDGING ALG THE NRN MID-ATLC COAST AND MARITIME INFLUENCE FROM SRN NEW ENGLAND. THE GRADIENT SHOULD BE RATHER PRONOUNCED FROM SW TO NE ON THE ORDER OF 15-20F. S/W RESPONSIBLE FOR THE LARGE MCS OVR IA/WI WILL TRACK EWD THRU THE GRT LKS THIS AFTN...ACCOMPANIED BY AN ONGOING CONVECTIVE SYSTEM WHICH SHOULD GRADUALLY LOSE STRENGTH AS IT SHIFTS FURTHER EWD AND DIVES INTO NRN AND ERN PA TONIGHT INTO EARLY THURS. && .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... MODELS SUGGEST THE HIGHEST PROBABILITY OF PCPN THUR NGT WILL BE ACRS THE NRN TIER. ANOTHER ROUND OF SHOWERS AND TSTMS APPEARS LKLY ON FRIDAY AS A SFC COLD FNT SINKS SLOWLY SWD FM THE LWR LAKES. AFTERNOON TEMPS ON FRI ARE PROGGED TO REACH THE MID 80S OVR THE LWR SUSQ VLY...WITH UPPER 70S AND LOW 80S IN THE ALLEGHENIES AND CENTRAL RIDGE AND VALLEY REGION. WITH HIGH DEWPOINTS FRIDAY AFTERNOON AND LESS HIGH CLOUDS...THERE WILL BE LESS OF A CAP...ESPECIALLY CONSIDERING THE PASSAGE OF AN 850 MB TROUGH FRIDAY AFTERNOON. GIVEN ENOUGH MOISTURE...HEATING AND INSTABILITY...AFTERNOON SHOWERS AND THUNDERSTORMS HAVE AN INCREASED PROBABILITY. EXPECT ANY AFTERNOON CONVECTION TO CONTINUE THROUGH THE EARLY EVENING HOURS. BEFORE ENDING AFTER SUNSET....THOUGH IT COULD PERSIST LONGER ALONG THE LAUREL HIGHLANDS. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... CONFIDENCE IS RATHER LOW DURING THE MEDIUM RANGE PERIOD. MODELS ARE DISAGREEING ON THE POSITION OF AN UPPER CYCLONE OVR SOUTH EASTERN CANADA. THE GFS/GEFS ARE FURTHER SOUTH WITH THE LOW AND THEREFORE INDICATE LOWER HGTS OVR THE NE STATES SUN-MON. THE NCEP DATA ALONG WITH THE CANADIAN WOULD SUGGEST A DRY/COOLER PD DURING THIS TIME AS HIGH PRES PUSHES A SFC FNT SOUTH OF THE MASON DIXON LINE. MEANWHILE...THE OP EC IS FURTHER NORTH WITH THE UPPER LOW CENTER AND BASICALLY KEEPS THE RING-OF-FIRE PATTERN GOING THRU THE WEEKEND. THERE IS A BROAD CONSENSUS FOR A MORE ORGANIZED PCPN EVENT BY NEXT TUE-WED AS A MID-UPPER TROUGH SHIFTS EWD FM THE UPPER MIDWEST AND CENTRAL PLAINS STATES. THERE IS SOME DISCREPANCY BETWEEN THE MODELS ON THE TIMING AND PROGRESSION OF THAT SYSTEM...THOUGH BOTH SYSTEMS BRING IT THROUGH MID TO LATE NEXT WEEK. THE EC IS FASTER COMPARED WITH EH GFS...WHERE THE GFS BEGINS AS A CLOSED LOW OVER THE CENTRAL U.S. AND THE EC IS THE OPPOSITE. BEGINNING AS A TROUGH...AND CLOSING OFF ONCE THE SYSTEM REACHES THE COAST.
