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.

UPPER LEVEL TROUGH OVER THE CWA. THERE IS SOME SMALL INSTABLITY ON
TUESDAY AND SPC HAS US IN GENERAL THUNDERSTORMS. NOT EXPECTING A
