NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
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, Aug 24, 11:46 AM CDT, 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 1146 AM CDT SAT AUG 24 2002 IN THE VERY SHORT TERM...UPDATED PUBLIC FORECAST...MAINLY TO CLEAN UP WORDING. WEAKENING CONVECTIVE COMPLEX HAVING A TOUGH TIME MOVING INTO SOUTHWEST MISSOURI...BUT CLOUD COVER WILL HOLD TEMPERATURES DOWN ALONG THE KS BORDER AND HAVE LOWERED AFTERNOON HIGHS A CATEGORY OR TWO. STILL LOOKS LIKE DIURNAL CONVECTION COULD REDEVELOP ALONG DIFFUSE FRONTAL ZONE OVER SOUTHERN MO. ANY OUTFLOW BOUNDARIES WILL ALSO STIR THE CONVECTIVE POT...SO WILL LEAVE RAIN CHANCES ALONE. PRELIMINARY LOOK AT THE EXTENDED FORECAST... MODELS STILL CONSISTENT MOVING 5H SHORTWAVE THROUGH MO SUNDAY THEN DEVELOPING CUTOFF OVER TN AND KEEPING IT THERE THROUGH THURSDAY. WITH BLOCKIER TYPE PATTERN..AS YOU MIGHT EXPECT...MODEL TO MODEL AND RUN TO RUN CONSISTENCY LACKING. IN GENERAL...IT LOOKS AS LIKE UPPER RIDGE IS STRONGER OVER THE CENTRAL U.S. AND ONLY ALLOWS LIMITED SHORTWAVE ENERGY TO DROP SOUTH INTO THE FORECAST AREA. FIRST INCLINATION IS TO REMOVE RAIN CHANCES THU AND FRI. DIURNAL CONVECTION A CONCERN FOR EASTERN COUNTIES A CONCERN CLOSER TO THE CUTOFF LOW NEXT WEEK...BUT SHOULD BE SPOTTY AND NOT ENOUGH TO MENTION IN THE FORECAST ATTM. .SGF... MO...NONE. KS...NONE. DSA
