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

Topeka, KS (KTOP), launched 00:00Z, 11.4 hours before the alert went out and 238 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.

A SECONDARY COLD FRONT WILL DROP SOUTH ACROSS NEBRASKA DURING THE
DAY. IN ADDITION...A TROUGH IN THE MIDDLE LEVELS OF THE ATMOSPHERE
IS EXPECTED TO CROSS THE AREA LATE THIS AFTERNOON INTO THE
EVENING. THE COMBINATION OF TEMPERATURES IN THE 80S AND AMPLE
LOW LEVEL MOISTURE WILL CREATE AN UNSTABLE ATMOSPHERE. ALL OF THESE
FACTORS SHOULD CAUSE SCATTERED THUNDERSTORMS TO ERUPT LATER THIS
AFTERNOON.

AT THIS TIME...THE GREATEST THREAT OF SEVERE WEATHER LOOKS TO BE
FROM LARGE HAIL AND DAMAGING WINDS.

EMERGENCY MANAGERS AND OTHER INTERESTED PARTIES SHOULD CONTINUE TO
MONITOR THE SITUATION THROUGHOUT THE DAY. AN UPDATE TO THIS PRODUCT
