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

THE SOUTHEASTERN PERMIAN BASIN...AIDED BY 60+F SURFACE DEWPOINT
BANKED ALONG THE TX/NM MOUNTAINS AND BENEATH 40-45KT LOW LEVEL JET.
A MID/UPPER LEVEL SHORTWAVE TROUGH PASSING ACROSS THE CENTRAL
