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.

Area forecast discussion, Jun 8, 10:38 AM EDT, 1 hour 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1038 AM EDT FRI JUN 8 2007 .SYNOPSIS... A COLD FRONT WILL MOVE ACROSS THE EASTERN GREAT LAKES AND OHIO VALLEY REGION THIS AFTERNOON AND EVENING. SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THIS FRONT. HIGH PRESSURE WILL BUILD INTO THE REGION OVERNIGHT BEHIND THE FRONT...REMAINING ACROSS THE AREA THROUGH THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... COLD FRONT CURRENTLY STRETCHING FROM FAR NORTHWEST INDIANA DOWN INTO SOUTHERN ILLINOIS. SHOWERS AND THUNDERSTORM ACTIVITY ACROSS SOUTHWEST INDIANA HAS BEEN SLOWLY INCREASING IN INTENSITY AND EXPECT THIS TREND TO CONTINUE AS IT PUSHES EAST INTO OUR AREA THROUGH EARLY AFTERNOON. MAINLY CLEAR SKIES ACROSS FA THIS MORNING HAVE ALLOWED TEMPS TO ALREADY CLIMB INTO THE LOW TO MID 80S AND LOWER 70S DEWPOINT ACROSS KENTUCKY WILL LIKELY ADVECT UP INTO THE SOUTHERN PORTIONS OF OUR AREA THROUGH EARLY AFTERNOON. THIS SHOULD LEAD TO CAPES IN THE 2000-3000 J/KG RANGE BY THE TIME THE STORMS MOVE IN...WITH THE BEST INSTABILITY EXPECTED TO BE ACROSS SOUTHEAST PORTIONS OF FA. PRIMARY SEVERE THREAT STILL APPEARS TO BE DAMAGING WINDS AS WIND PROFILE IS PRETTY UNIDIRECTIONAL. SOME MID LEVEL DRYING IS ALSO PROGGED WHICH WILL ALSO ENHANCE DAMAGING WIND POTENTIAL. WETBULB ZEROES FAIRLY HIGH...UP AROUND 11 K FEET...SO HAIL APPEARS TO BE A SMALLER THREAT...BUT GIVEN POSSIBILITY OF STRONG UPDRAFTS SOME SEVERE HAIL WILL ALSO BE POSSIBLE. HAVE UPDATED FORECAST TO BUMP UP POPS...ESPECIALLY ACROSS THE SOUTH WHERE WILL GO WITH CATEGORICAL WORDING. HAVE LEFT TEMPS ALONE RIGHT NOW BUT WILL HAVE TO KEEP AN EYE ON THEM...PARTICULARLY ACROSS THE SOUTHEAST WHERE THEY MAY SNEAK INTO THE LOWER 90S IF THE CLOUDS SHIELD HOLDS OFF LONG ENOUGH. && .SHORT TERM /SATURDAY THROUGH SUNDAY/... SFC HIGH PRESSURE WILL BUILD ACRS THE REGION ON SATURDAY...AND THEN IT WILL REMAIN ACRS THE REGION ON SUNDAY. COOLER TEMPERATURES WILL BE IN THE OFFING AS 850 MB TEMPS DROP INTO THE +9 TO +14 DEGREE RANGE. HIGHS ON SATURDAY WILL RANGE FROM THE MID 70S NORTH TO AROUND 80 SOUTH. LOWS SATURDAY NIGHT WILL BE QUITE COOL GIVEN THAT A GOOD RADIATIONAL COOLING SET UP IS EXPECTED. THUS...MID 40S EAST TO THE LOWER 50S WEST LOOK LIKE A GOOD BET. FOR SUNDAY...HAVE TRIMMED TEMPS DOWN SOME AS A COOL START...COMBINED WITH LOWER THAN EXPECTED 850 MB TEMPS...KEEP HIGHS FROM WARMING UP INTO THE MID MID 80S. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... SUNDAY NIGHT THROUGH TUESDAY...THE MODELS ARE IN DECENT AGREEMENT WITH SFC HIGH PRESSURE ENTRENCHED OVER THE EASTERN US AND H5 RIDGING JUST TO THE WEST OF THE AREA. ALTHOUGH ISOLATED TS ACTIVITY CANNOT BE RULED OUT...CONDITIONS FOR LARGE SCALE ORGANIZED ACTIVITY ARE NOT FAVORABLE AT THIS TIME. TEMPERATURES WILL LIKELY BE ABOVE NORMAL...AND ARE TRENDING HIGHER. BY WEDNESDAY...THE H5 RIDGE WILL MOVE EASTWARD A BIT...WITH SCATTERED STORMS BECOMING MORE PLAUSIBLE. && .AVIATION /14Z FRIDAY THROUGH TUESDAY/... COLD FRONT CURRENTLY ACRS MID MISSISSIPPI VLY WITH CONVECTIVE ACTIVITY QUICKLY DIMINISHING ACRS ILLINOIS. CLOUD TOPS CONTINUE TO WARM AS CI SHIELD DRIFTS SLOWLY EAST. OTHER THAN SCT SC/CU IN TURBULENT S/SW FLO...ALL TERMINALS STARTING OUT MORNING WITH SUNSHINE. HEATING THIS MRNG SHOULD ALLOW FOR QUICK DESTABILIZATION OF THE LWR ATMOSPHERE...WITH MLCAPES PROGGED TO 2000 J/KG BY MIDDAY. AS REMNANTS OF OVERNIGHT CONVECTION APPCH FCST AREA BY LATE MRNG...EXPECT TSTMS WILL BEGIN TO DVLP AND BECOME WIDESPREAD BY ERLY AFTN WITH COMBINATION OF INSTABILITY AND LO LVL CONV. APPCHG TAIL OF 90KT UPR JET AND ELONGATED VORT LOBE SHOULD PROMOTE MID/UPR LVL DIFFLUENCE. THE BETTER MID/UPR LVL FORCING WILL BE FOCUSED ACRS NRN OH WHILE THE GREATER INSTABILITIES AND DEEPER MOISTURE WILL BE DISPLACED FURTHER SOUTH. EVEN THOUGH THESE PARAMETERS ARE SLIGHTLY OUT OF PHASE...SHOULD STILL SEE BKN LINE OF TSTMS ACRS FCST AREA BY ERLY/MID AFTN. HAVE INTRODUCED VCTS FOR ALL TERMINALS FOR ENTIRE AFTN WITH A FOUR HOUR WINDOW WHEN POTENTIAL FOR TSTMS IS GREATEST AT EACH OF THE TERMINALS. WINDS WILL REMAIN GUSTY THROUGHOUT THE DAY...VEERING FROM S/SW THIS MRNG TO W/NW BY 00Z. HIGHER WIND GUSTS WILL BE POSSIBLE WITH ANY TSTM. FROPA IS EXPECTED BY LATE AFTN/ERLY EVNG WITH FRNTL BNDRY PUSHING SOUTH OF THE OHIO RIVER DURING THE EVNG HOURS WITH DRY CONDITIONS AT ALL OF THE TERMINALS BY LATE EVNG.
