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, Jul 11, 8:35 PM CDT, 31 minutes before

MESOSCALE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
835 PM CDT FRI JUL 11 2003

.DISCUSSION...
STRONG TO SEVERE THUNDERSTORMS CONTINUE TO FORM ALONG THE GREATEST
85H THETA-MOISTURE AXIS AND SURFACE CONVERGENCE IN EAST CENTRAL
KANSAS...SOUTH/SOUTHWEST OF MCI/TOP. RADAR INDICATED TOPS OVER 50K
WITH STRONG ROTATION IN EACH INDIVIDUAL CELL IN THIS AREA.
HOWEVER...CAPES LOWER IN SOUTHEAST KANSAS/WEST CENTRAL
MISSOURI...AND SOME OF THE STRONGER CELL HAVE DECREASED IN OVERALL
INTENSITY AS IT MOVES INTO FAR NORTHERN PARTS OF BOURBON AND VERNON
COUNTIES. PROPAGATION CONTINUES TO THE SOUTHEAST AT 35 TO 45 KTS
WHICH TAKES TO BULK OF THE ACTIVITY INTO JOPLIN/SPRINGFIELD AREAS
BETWEEN 10 AND 11 PM.

PROFILERS STILL INDICATE S/SW BETWEEN 15 TO 30 KTS BELOW 85H. ABOVE
85H WINDS VEER TO THE W/NW AND INCREASE TO 35 TO 55 KTS. DEEP LAYER
SHEAR WILL CONTINUE OVERNIGHT...WHICH MEANS ORGANIZED CONVECTION
WILL CONTINUE...ALTHOUGH IT MIGHT NOT BE SEVERE. HOWEVER...LATEST
MODEL INFORMATION CONTINUES TO THREAT OF PRECIPITABLE WATER VALUES
INCREASING...AND DEEP MOISTURE POOLING OVER SOUTHERN MISSOURI
OVERNIGHT. THIS MEANS THE LIKELIHOOD OF HEAVY RAINFALL WITH
LOCALIZED FLOODING IS POSSIBLE. THE FLOODING WILL HIGHLY DEPEND UPON
HOW THE COMPLEX OVER EASTERN KANSAS DEVELOPS DURING THE NEXT FEW
HOURS AND HOW THE LOW LEVEL JET AXIS FORMS OVERNIGHT.

  MORE NUMEROUS TONIGHT AS THE UPPER LEVEL DISTURBANCE GETS CLOSER
  TO THE AREA AND A LOW LEVEL JET DEVELOPS. STRONG WINDS ALOFT WILL

  CONDITIONS FOR SOME OF THE THUNDERSTORMS TO BECOME SEVERE TONIGHT.

  CONTAIN HEAVY RAINFALL. AT THIS TIME CONDITIONS DO NOT APPEAR
  FAVORABLE FOR WIDESPREAD OR SIGNIFICANT FLOODING...BUT SOME

  RAINFALL OF THIS MAGNITUDE COULD LEAD TO PONDING OF WATER OR
  MINOR FLOODING IN THE TYPICAL LOW LYING AND POOR DRAINAGE AREAS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
