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
Pittsburgh, PA (KPIT), launched 12:00Z, 7.7 hours before the alert went out and 156 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 Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 18, 3:02 PM EDT, 41 minutes earlier.
Area forecast discussion, Jul 18, 3:02 PM EDT, 41 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 302 PM EDT MON JUL 18 2011 .SYNOPSIS... A DISSIPATING COLD FRONT WILL MOVE INTO THE AREA LATE TONIGHT INTO TUESDAY THEN HIGH PRESSURE WILL REBUILD OVER THE AREA LATER TUESDAY INTO WEDNESDAY BEFORE SHIFTING INTO THE SOUTHEAST FOR THE REST OF THE WEEK. && .NEAR TERM /THROUGH TONIGHT/... DIFFUSE WEAK COLD FRONT SAGGING INTO LAKE ERIE TONIGHT WILL HELP TO PROVIDE FOCUS FOR CONVECTIVE DEVELOPMENT. COMPLEX OVER EASTERN LOWER MI SHOULD MOVE ACROSS THE CWA THROUGH THIS EVENING. QUESTION IS WHETHER LAKE STABILITY WILL DISSIPATE CELLS TRYING TO CROSS THE CENTRAL AND EASTERN PART OF THE LAKE AND THUS LOWER THREAT FOR ASSOCIATED DOWN FLOW LAKESHORE COUNTIES. HAVE PLAYED LOWER POPS FOR THE LAKE SHADOW EFFECT. AS AIRMASS COOLS AND BECOME MORE STABLE...EXPECT OVERALL COVERAGE OF TSRA TO LESSEN SO WILL CONTINUE THAT TREND IN FORECAST. LIGHT WIND FLOW WILL NOT BE ABLE TO BRING MUCH DRIER AIR INTO THE CWA TONIGHT SO EXPECT A MUGGY NIGHT WITH LOWS IN THE LOW TO MID 70S AND DEWPOINTS REMAINING AROUND 70. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... EXPECT AIRMASS TO BECOME UNSTABLE AGAIN ON TUE. BEST GUESS IS THAT WEAK FRONTAL BOUNDARY WILL PUSH SOUTH OF LAKESHORE COUNTIES FOR THE AFTERNOON SO THINK THE FOCUS FOR CONVECTIVE DEVELOPMENT WILL BE OVER THE SOUTHERN 2/3 OF THE CWA. THUS LOWER POPS IN ORDER FOR THE LAKESHORE COUNTIES. THERE MAY BE A FEW LINGERING CELLS TUE EVENING IN THE SOUTH...OTHERWISE EXPECT A DRY TUE NIGHT AND WED MORNING. QUESTION IS WHETHER CONVECTION CAN GET GOING OVER THE UPPER LAKES EARLY WED MORNING AND THEN DROP SE INTO OUR AREA LATER WED. THIS THREAT COMBINED WITH WEAK WARM ADVECTIVE LIFT AND AFTERNOON INSTABILITY SHOULD AT LEAST WARRANT A SLIGHT CHANCE IN THE FORECAST. ADDITIONAL CONVECTIVE COMPLEXES COULD MAKE A RUN AT THE AREA LATE WED NIGHT THROUGH THU NIGHT BUT WITH SO MUCH UPPER RIDGING IN PLACE WILL KEEP THREAT TO LOW END SLIGHT CHANCE OR LESS. THE WEAK COLD FRONT WILL BRIEFLY STOP THE TEMP RISE FOR TUE INTO WED BUT HOT TEMPS LOOK ALMOST CERTAIN FOR THU ALONG WITH A HEAT ADVISORY. && .LONG TERM /FRIDAY THROUGH MONDAY/... WARM AND HUMID WEATHER WILL CONTINUE DURING THE PERIOD. THIS WILL RESULT IN AT LEAST SMALL CHANCES FOR AFTERNOON SHOWERS AND STORMS EACH DAY. BEST CHANCES FOR RAIN DURING THE PERIOD APPEAR TO BE FRIDAY AND AGAIN MONDAY WITH WEAK FRONTAL SYSTEMS IN THE AREA. TEMPS DURING THE PERIOD WILL AVERAGE 10 TO 15 DEGREES ABOVE NORMAL WITH HIGH HUMIDIFIES MAKING IT FEEL EVEN WARMER. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... LOT'S OF UNCERTAINTY TODAY AS FAR AS TIMING AND COVERAGE OF STORMS GOES. THINK MOST AREAS WILL SEE THUNDER THE NEXT 12 HOURS. BEST CHANCES APPEAR TO BE LATE THIS AFTERNOON AND EVENING. ALREADY SEEING SOME DEVELOPMENT AND STORMS SE OF KTOL COULD AFFECT KMFD IN THE NEXT HOUR OR SO. WILL GIVE ALL AREAS A FEW HOURS OF THUNDER LATER THIS AFTERNOON. SOME SHOWERS LIKELY THROUGH AROUND MIDNIGHT IF NEW GUIDANCE IS TO BE BELIEVED. EXPECT WIDESPREAD MVFR VSBY AFTER SUNSET WITH PATCHY IFR LIKELY LATE TONIGHT. SOME HINT FROM THE NEW GUIDANCE THAT MVFR TO IFR CIGS COULD DEVELOP IN THE MORNING. SW TO W FLOW WILL BECOME LIGHT AFTER DARK. OUTLOOK...VFR EXCEPT THUNDERSTORMS INTO THE OVERNIGHT AND REDUCED VSBY DURING EARLY MORNING FOG/HAZE. && .MARINE... HIGH PRESSURE WILL BE IN CONTROL THROUGH THE ENTIRE PERIOD AS IT EXTENDS A RIDGE WEST FROM THE ATLANTIC COAST INTO THE GREAT LAKES REGION. A WEAK COLD FRONT WILL SLIDE DOWN ACROSS THE LAKE FROM THE NORTH TONIGHT AND REMAIN NEARLY STATIONARY OVER OHIO AND PENNSYLVANIA. THE FRONT WILL LIFT BACK NORTH AS A WARM FRONT WEDNESDAY. WINDS EXPECTED TO BE RATHER LIGHT ACROSS THE LAKE THROUGH THE PERIOD WITH WAVES RUNNING AROUND 2 FEET OR LESS. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...NONE. PA...NONE.
