The radar
The Cleveland radar (KCLE), 137 km from the middle of the area, began a volume at 17:22 UTC, the scan nearest the moment this went out.

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
Pittsburgh, PA (KPIT), launched 12:00Z, 5.4 hours before the alert went out and 160 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, Dec 11, 11:29 AM EST, 52 minutes before
Area Forecast Discussion
National Weather Service Pittsburgh PA
1129 AM EST Sat Dec 11 2021
.SYNOPSIS...
Strong wind, rain, and embedded thunderstorms will accompany the
arrival a cold front today, with the return of dry and seasonable
conditions Sunday through early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Recent wly wind shift in sfc obs, in conjunction with mosaic radar
reflectivity, suggests a sfc cold front located near the western OH
border moving east toward the forecast area. Pre-frontal showers
with some, embedded storms continue to plague the immediate area
within the warm sector, with occasional bouts of gusty wind possible
in more organized convection, denoted via local SPS issuances.
Though, confidence in widespread, gusty wind will increase with the
arrival of that cold front this afternoon as sfc based
instability/deeper mixing is realized. Recent sfc obs across MI, IN,
and OH confirm this as wind gusts in excess of 46 mph are being
realized. Gusty wind should persist even after the passage of the
cold front as llvl lapse rates steepen and mix down strong wind near
850mb in conjunction with a large pressure gradient overhead. For the
reasons listed above, a Wind Advisory remains in effect for the
entire forecast area through midnight.
Despite widespread rain, flooding concerns should be limited overall
due to rapid system progression, lack of sustained moisture
convergence, and convective element speed.
Very mild temperature from earlier this morning will lower through
the remainder of the day, trending back toward average values
overnight. Cold advection may support the changeover of remnant rain
showers to snow showers after sunset, though little to no
accumulation is expected provided increased subsidence aloft.
&&
.SHORT TERM /SUNDAY THROUGH TUESDAY/...
Broad central CONUS high pressure should begin to build Sunday, with
a return to dry and seasonable conditions provided nw flow aloft.
Flow should become more flattered by Monday in response to the
interaction of a northern stream, active shortwave pattern across
Canada and broadening sern CONUS high pressure, with subtle height
rises supporting the return of above average temperature by Tuesday.
Otherwise, dry conditions are expected to prevail through the
period.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
Long range guidance suggests the eventual breakdown of high pressure
by Tues night as low pressure deepens and ejects out from the Four-
Corners region. Moist advection within return, sw flow on the van of
that low should support periodic precipitation chances, mostly in the
form of rain showers, provided continued, mild temperature values.
&&
.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
A swath of light to moderate rain showers with VFR/MVFR restrictions
exiting east of the region will be quickly followed up by another
line of shra and iso tstm ahead of an incoming cold front this
aftn/eve. A tight sfc gradient will yield 20-30kt SSW winds ahead of
the boundary, and 30-40kt W winds after fropa (with added boost of
steepening lvl lapse rates).
Dry conditions and an MVFR stratus deck will develop quickly in the
wake of FROPA, with wind gradually diminishing as llvl jet and sfc
gradient weaken. Dry air and subsidence is expected to result in a
W-E clearing sky/VFR conditions Sunday morning.
.Outlook...
VFR should return Sun thru Wed under high pres.
