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

Omaha, NE (KOAX), launched 00:00Z, 11.9 hours before the alert went out and 166 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.

624 AM CDT SAT JUN 23 2012

.AVIATION...12Z KGRI TAF. THUNDERSTORMS HAVE FINALLY PUSHED OFF TO
THE EAST OF THE TAF SITE THIS MORNING. HOWEVER...THE MAIN CONCERN
FOR THE TAF SITE WILL CENTER AROUND STRONG GUSTY WINDS THAT WILL
LINGER THROUGH THE MID MORNING HOURS. BEHIND THE THUNDERSTORMS AN
AREA OF LOW PRESSURE INCREASED SOUTHERLY WINDS TO NEAR 40 KTS
SUSTAINED WITH WIND GUSTS UP TO 50 AND 55 KTS. EXPECTING THESE
WINDS TO DECREASE THROUGH THE MORNING HOURS. SKIES WILL BECOME
MOSTLY SUNNY THROUGHOUT THE DAY WHILE TEMPERATURES WARM UP TO THE
MID 90S TO NEAR 100. TOWARDS THE END OF THE PERIOD...SOUTH WINDS
WILL SWITCH TO THE EAST BEFORE BECOMING LIGHT AND VARIABLE.
