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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
305 AM CDT SUN APR 24 2011

.DISCUSSION...ELEVATED SHOWERS AND THUNDERSTORMS CONTINUE TO
DEVELOP ACROSS PARTS OF THE AREA NORTH OF THE FRONT ARCING FROM SE

SUNDAY NIGHT AS MAIN PORTION OF THE UPPER TROUGH ADVANCES EASTWARD
TOWARD THE AREA. THIS FEATURE THEN LIFTS NEWD ACROSS THE AREA
MONDAY WITH SURFACE WAVE DEVELOPING ON THE FRONT OVER N TX/SW OK
BEFORE LIFTING NEWD INTO MO MONDAY AFTERNOON. THIS SHOULD SHIFT
MAIN THUNDERSTORM THREAT TOWARD SERN PARTS OF THE FA FOR MONDAY
