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

Fort Worth, TX (KFWD), launched 00:00Z, 5.9 hours before the alert went out and 163 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 AREA WITH SOME SITES SHOWING 5SM BUT HUMAN OBSERVERS INDICTING
VSBY MUCH HIGHER SO FAR. WILL SHOW MVFR VSBY FOR A COUPLE MORE

HANDLE ANY EXTENSIONS/ADJUSTMENTS WITH GUSTY NORTHWEST WINDS BEHIND
THE COLD FRONT MONDAY. DESPITE MOSTLY SUNNY SKIES MONDAY...HIGHS
WILL ONLY REACH INTO THE 60S...SO IT'LL FEEL COOL.

ZONAL FLOW AND INFLUENCE OF CONTINENTAL HIGH PRESSURE AT THE

SUNSHINE. TEMPERATURES WILL GRADUALLY WARM DURING THIS TIME AS
S/SE WINDS RETURN TO THE REGION TUES-FRI...BRINGING GULF MOISTURE
BACK UP INTO THE AREA BY THE END OF THE WEEK. ANOTHER UPPER
