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

Green Bay/Straub, WI (KGRB), launched 00:00Z, 9.8 hours before the alert went out and 46 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.

AFTER THIS MORNING STORMS...ANTICIPATE SOME DECREASE IN COVERAGE
BEFORE STORMS INCREASE AGAIN THIS AFTERNOON WITH THE H850 TROUGH
SLIDING THROUGH THE UNSTABLE AIR MASS WITH CAPES OF NEAR 1500 THIS
AFTERNOON. SEVERE POTENTIAL WOULD DEPEND ON AMOUNT OF SUN FOR
FURTHER DESTABILIZATION. THE CHANCE OF STORMS WILL LINGER
INTO TUESDAY BUT LIKELY MORE FOCUSED EARLY IN THE DAY OVER NORTH
CENTRAL AND NORTHEAST WISCONSIN DUE TO FRONT DROPPING SOUTH OVER
THE AREA AND THE UPPER RIDGE MOVING INTO THE AREA FROM THE WEST.
