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 12:00Z, 10.5 hours before the alert went out and 173 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.

Area forecast discussion, Jun 11, 5:15 PM EDT, 1 hour 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 515 PM EDT SAT JUN 11 2011 .SYNOPSIS... A SLOW MOVING FRONTAL COMPLEX WILL KEEP SHOWERS AND THUNDERSTORMS IN THE AREA OVERNIGHT. AS THESE DISTURBANCES MOVE GRADUALLY EASTWARD SUNDAY AND EARLY NEXT WEEK...THE COVERAGE OF SHOWERS WILL SLOWLY DIMINISH. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 5 PM UPDATE... AS AN MCV TRACKS THROUGH PA THIS EVE...SHRA/TSRA WILL BE MOST NUMEROUS. A FEW STG/SVR TSRA CAN'T BE RULED OUT EARLY THIS EVE...BUT WE SHOULD BE TRANSITIONING TO MORE OF A HEAVY RAIN SITUATION WITH TIME. LATER TNT...WEAK SFC COLD FRONT WILL SLOWLY ENTER THE CWA FROM THE W...KEEPING THE THREAT OF SHWRS IN. HOWEVER...WITH SOME HGT RISES/NVA ALOFT BEHIND THE MCV...SHRA SHOULD BECOME MORE SCATTERED IN NATURE. && .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/... 510 PM SAT UPDATE... AFOREMENTIONED SFC COLD FRNT WILL SLOWLY TRANSITION EWD SUN/SUN NIGHT...TAKING THE THREAT OF CONVECTION WITH IT. STILL ENOUGH MOIST/INSTAB SUN AFTN/EVE IN OUR ERN ZONES...FOR A CHANCE OF TSRA. MON THROUGH TUE...SYNOPTICALLY...A CLOSER UPPER-LVL LOW IS PROGGED TO SINK SEWD FROM ONT/QUE ACROSS NEW ENG. CNTRL NY/NE PA WILL BE ON THE WRN FRINGE OF THIS SYSTEM'S SPHERE OF INFLUENCE. AT LEAST SOME DIURNAL SHRA/ISOLD TSRA ARE ANTICIPATED...GIVEN THE COLD POOL ALOFT. HOWEVER...A GOOD CHUNK OF THE TIME COULD END UP BEING RAIN- FREE...ESPECIALLY AS WE HEAD THROUGH TUE...WHEN THE SYSTEM SHOULD BE GRADUALLY SHIFTING EWD. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... 2 PM UPDATE...WITH THE POTENTIAL FOR SEVERE WX UPON US...THE LONG TERM FORECAST HAS BEEN DONE EARLY AND POPULATED WITH MAINLY HPC GUIDANCE. MAIN IDEAS ARE A DRY START TO THE EXTENDED WITH ONE UPPER LEVEL LOW DEPARTING TO OUR EAST TUESDAY EVENING. DRY WEATHER WEDNESDAY AND MOST OF THURSDAY BEFORE A SECOND UPPER LEVEL LOW MEANDERS TOWARD OUR AREA LATE THURSDAY INTO FRIDAY. AS USUAL...TIMING AND PLACEMENT DIFFERENCES WILL PROBABLY COME UP BETWEEN NOW AND THEN. THIS IS WHY I LIKE THE HPC GUIDANCE OF JUST CHANCE POPS LATE THURSDAY THROUGH FRIDAY. UPPER LOW SLOWLY PULLS EAST BY EARLY NEXT WEEKEND WITH DRIER WEATHER BUILDING IN. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... 2 PM UPDATE...WARM FRONT TRYING TO MOVE THROUGH OUR SOUTHERN TERMINALS NOW WITH NUMEROUS SHOWERS AND NOW THUNDERSTORMS DEVELOPING. MAIN IMPACTS THROUGH 21Z WILL BE TO KITH...KELM AND KAVP. KEPT A CB GROUP OF MVFR CIGS AND VSBYS IN THE TAFS TO SHOW THIS POTENTIAL FOR THUNDER. AS THUNDERSTORMS GET CLOSER TO THE TERMINALS....IE IN ABOUT A 2 HOUR WINDOW PRIOR TO ARRIVAL...WILL UPGRADE TO TSRA. A DISTURBANCE NOW MOVING INTO WESTERN PA WILL CAUSE MORE SHOWERS AND THUNDERSTORMS TO DEVELOP LATER THIS EVENING...WITH ALL TERMINALS LIKELY SEEING SOME IMPACT IN THE 21Z TO 03Z TIME-FRAME. FOR NOW WILL KEEP WITH MVFR CIGS AND VSYBS...WITH A CB GROUP TO SHOW CHANCES FOR THUNDER. TSRA GROUPS WILL LIKELY BE NEEDED AS WE DRAW CLOSER TO THE EVENT. AFTER THE SHOWERS PULL OUT ALL GUIDANCE INDICATE IFR CIGS AND MVFR VSBYS OVERNIGHT. MOST CONFIDENT OF THIS AT THE ELEVATED SITES (KBGM/KITH) AND CONTINUED TO SHOW IFR HERE. SHOWED LOW END MVFR CIGS ELSEWHERE TO SHOW THE POTENTIAL FOR IFR. BASED ON GUIDANCE HOWEVER...VERY LIKELY EVERYONE WILL SEE SOME IFR IN THE 06Z TO 14Z TIME-FRAME.
