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

Norman, OK (KOUN), launched 12:00Z, 11.6 hours before the alert went out and 193 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.

NATIONAL WEATHER SERVICE TULSA OKLAHOMA
343 PM CDT SAT MAY 24 2003

NORHTWEST FLOW CONTINUES TO COMPLICATE FORECAST THROUGH SUNDAY.
INITIAL EARLY CONVECTION APPEARS TO HAVE STABILIZED THE AIRMASS AND
SHOULD ELIMINATE FURTHER CHANCES OF PRECIP.  HOWEVER...SATELLITE
SHOWS MORE CONVECTION DEVELOPING OVER WESTERN KANSAS WHICH WILL HAVE
AT LEAST A SLIGHT CHANCE OF MOVING INTO THE FORECAST AREA DURING THE
NIGHT.  STILL CANNOT COMPLETELY RULE OUT PRECIP FOR SUNDAY...AND
WILL KEEP A SLIGHT CHANCE THROUGHOUT THE DAY.  WILL END CHANCES OF
PRECIP BY SUNDAY EVENING.

GENERALLY FOLLOWED THE MAV MOS CLOSELY.  EXPECT TEMPS TO BECOME
QUITE COOL MONDAY MORNING AND TUESDAY MORNING AS THE SURFACE HIGH
SETTLES OVER THE AREA AND ALLOWS FOR STRONG INVERSIONS.

MADE NO SIGNIFICANT CHANGES TO THE EXTENDED...BUT DID ADD A SLIGHT
CHANCE OF PRECIP ON DAY 7...AS COLDFRONT DROPS INTO THE AREA.
