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

Omaha, NE (KOAX), launched 12:00Z, 11.3 hours before the alert went out and 217 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.

THE MODELS PROGRESSING THRU THE PD. THEY ARE IN AGREEMENT IN THE
MIDDLE OF THE WEEK AND THRU FRIDAY...IN KEEPING THE LARGE CLOSED OFF
UPPER VORTEX MEANDERING THRU THE EASTERN U.S.. THIS SHOULD SETUP A
SFC ANTICYCLONE DRAINING DOWN THE MN AND IA AREAS WED NIGHT THRU
FRIDAY. THIS FLOW WL BE DRY AND FAIRLY MILD AS THE AIR IS QUITE
MODIFIED AND THE GFS LIKELY TOO COLD WITH ITS TEMPS OFF THE SFC. AT
THAT POINT THE 00Z/06Z GFS SOLNS EXIT THE ERN U.S. LOW AWAY TOWARD
NEW ENGLAND THRU THE WEEKEND...ALLOWING A DIRTY RIDGE TO SETUP
BETWEEN THAT VORTEX AND ANOTHER CLOSED LOW IN THE SW U.S.. THIS SOLN
DOES NOT SEEM REAL REASONABLE...AND PREFER THE ECMWF/CAN SPECTRAL
