Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS LSX wrote it up.
A warm front lifted northward through the region...triggering showers and thunderstorms. Some of the storms caused flash flooding.

.DISCUSSION...
/330 AM CDT WED JUN 25 2008/
Q-STATIONARY FRONT DRAPED ACROSS MISSOURI ALONG WITH STRONG
NOCTURNAL LOW LEVEL JET HAS TOUCHED OFF A HEAVY RAIN PRODUCING
MCS. THE HEAVIEST RAIN HAS BEEN FALLING ACROSS NORTH CENTRAL AND
CENTRAL MISSOURI...JUST OUTSIDE OUR CWFA. HOWEVER...RADAR
ESTIMATES OF 2-3 INCHES OF RAIN AT THIS TIME WITH MORE ON THE WAY
ACROSS KNOX...LEWIS...MARION...SHELBY...AND ADAMS COUNTIES. HAVE
THEREFORE DECIDED TO CONTINUE THE FLASH FLOOD WATCH THROUGH NOON
TODAY. IT STILL LOOKS...BASED ON RADAR TRENDS...LIKE THE SOUTHERN
EXTENT OF THE HEAVY RAIN WILL FALL WITHIN THE WATCH AREA THIS
MORNING SO DID NOT EXPAND THE AREA AT THIS TIME.
OUTFLOW BOUNDARY FROM THIS MORNINGS MCS WILL LIKELY BE HANGING
AROUND THE CWFA THIS AFTERNOON. THIS BOUNDARY WOULD PROVIDE A GOOD
FOCUS FOR ADDITIONAL THUNDERSTORM DEVELOPMENT. RUC IS FORECASTING
MLCAPES GREATER THAN 1600 J/KG AND MUCAPES GREATER THAN 4000
JOULES BY 18Z. THIS IS OBVIOUSLY MORE THAN ENOUGH ENERGY FOR
THUNDERSTORMS TO REDEVELOP. NOT SURE THOUGH WHAT THE COVERAGE WILL
BE THIS AFTERNOON SO MAINLY KEPT JUST CHANCES GOING.
THE SURFACE BOUNDARY MOVES FURTHER NORTH INTO IOWA TONIGHT AND
APPEARS TO TAKE THE THREAT FOR HEAVY RAIN WITH IT AT LEAST THROUGH
FRIDAY MORNING. THERES STILL THE CHANCE THAT WELL SEE SOME SCATTERED
THUNDERSTORMS...BUT ORGANIZED MCS ACTIVITY SHOULD STAY NORTH OF
THE CWFA WHERE THE LOW LEVEL JET MOVES OVERTOP OF THE BOUNDARY AND
INTERACTS WITH SEVERAL PASSING SHORTWAVES. UNFORTUNATELY THIS
MEANS MORE WATER IN THE MISSISSIPPI RIVER SYSTEM. NOT SURE YET HOW
THIS WILL IMPACT RIVER FORECASTS...WHETHER THE RIVER WILL RISE
AGAIN...OR IF IT WILL JUST DELAY THE PREVIOUSLY FORECASTED FALL.
EITHER WAY THIS IS NOT GOOD NEWS.
THE NEXT SHOT FOR HEAVY RAINFALL LOOKS TO BE FRIDAY NIGHT AND
SATURDAY AS A SLOW MOVING COLD FRONT MOVES SOUTHEAST ACROSS
MISSOURI AND ILLINOIS. HPC GUIDANCE PRINTED OUT OVER AN INCH OF
QPF ACROSS THE AREA FRIDAY NIGHT. DID NOT GO THAT HIGH IN MY QPF
FORECAST YET AS THERE IS STILL A LOT OF UNCERTAINTY IN THE QPF
FORECAST OUT THAT FAR...THOUGH THIS IS OBVIOUSLY A POSSIBILITY THAT
WILL HAVE TO BE WATCHED CLOSELY OVER THE NEXT COUPLE OF DAYS.
