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.

Area forecast discussion, Apr 3, 12:37 AM CDT, 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1237 AM CDT TUE APR 3 2012

.AVIATION...A COLD POOL WILL PUSH THUNDERSTORMS AND MVFR CEILINGS
EASTWARD THROUGH THE CENTRAL OKLAHOMA TAF SITES THIS MORNING.
INTENSITY OF THE STORMS WILL DECREASE...AS DRIER AIR IS INGESTED
FROM THE EAST. SOMEWHAT STRONGER THUNDERSTORMS WERE REDEVELOPING
NEAR KLAW TO KSPS...AND SHOULD AFFECT THOSE TAF SITES...SUSTAINED
BY JUXTAPOSITION OF THE LOW LEVEL JET WITH A SLOW MOVING OUTFLOW
BOUNDARY.

THEN EXPECT ORGANIZED RAIN TO REFOCUS ALONG A COLD FRONT IN
NORTHERN OKLAHOMA DURING THE MORNING...FOLLOWED BY MORE WIDELY
SCATTERED STORMS IN THE AFTERNOON/EVENING. FOLLOWED THE NAM
CLOSELY. THE FRONT WILL BEGIN MOVING LATE IN THE PERIOD...BRINGING
A WIND SHIFT THROUGH WESTERN OKLAHOMA.
