Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Detroit, MI (KDTX), launched 12:00Z, 9.0 hours before the alert went out and 187 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.

MAKING THE LAPES RATES STEEP AS LEAST THROUGH THE AFTERNOON. AS THE
TROF SHIFTS EAST THAT WILL KEEP THE PRECIPITATION GOING TONIGHT. AT
THIS TIME WITH PLENTY OF CLOUD COVER ALL DAY THAT WAS HELPING THE
STORMS FROM NOT BECOMING SEVERE. SOME OF THEM HAVE BEEN CLOSE. IT IS
STILL POSSIBLE A FEW COULD BE SEVERE THROUGH THIS EVENING...HAIL
WOULD BE THE PRIMARY THREAT. THE BIGGER CONCERN IS SOME LOCALLY
HEAVY RAIN. WITH THE AIRMASS DRYING OUT ALOFT THAT SHOULD HELP KEEP
THE RAINFALL DOWN BUT CANT RULE OUT A FEW SPOTS APPROACHING THE
FLOOD GUIDANCE. MOST LOCATIONS WILL GET UNDER AN INCH...HOWEVER SOME
COULD BE UP TO 2 INCHES. THE TROF WILL MERGE WITH THE COLD FRONT
THURSDAY AND WITH THE TROF CLOSE SOME SHOWERS AND THUNDERSTORMS
COULD CONTINUE IN THE EAST ESPECIALLY IN THE AM AND EARLY AFTERNOON.
GFS AND WRF AGREE WITH THAT...THE WRF MAY BE A LITTLE QUICKER. THE
MODELS HANG UNTO THE MOISTURE SO THURSDAY WILL BE MOSTLY CLOUDY. THE
CLOUDS WILL DECREASE THURSDAY NIGHT FROM WEST TO EAST. WITH SOME
MOISTURE HANGING AROUND WILL JUST MAKE IT PARTLY CLOUDY.
