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
Topeka, KS (KTOP), launched 00:00Z, 9.2 hours before the alert went out and 208 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.

Area forecast discussion, Jun 10, 3:30 AM CDT, 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 330 AM CDT TUE JUN 10 2003 MAIN FORECAST CONCERNS IS WITH WHERE BOUNDARY WILL SET UP TODAY AND REDEVELOPMENT OF STORMS TO TAKE PLACE. THEN LOCATION OF MCS DEVELOPMENT TONIGHT AND AGAIN WEDNESDAY NIGHT INTO THURSDAY. ALSO THE EFFECT ON TEMPERATURES THESE MCS FEATURES WILL HAVE. IN THE SHORT TERM...CURRENT CONVECTION IS EXPECTED TO BE IN SOUTHERN HALF OF FORECAST AREA AT START OF DAY. THIS SHOULD LEAVE AN OUTFLOW BOUNDARY ACROSS SOUTHERN PART OF FORECAST AREA FOR THIS AFTERNOON...WITH STILL SOME SCATTERED THUNDERSTORMS POSSIBLE IN ITS VICINITY. ALSO EXPECTING MORE WIDESPREAD DEVELOPMENT INTO SOUTHWEST PART OF FORECAST AREA BY LATE IN THE DAY AS SHORT WAVE MOVING EAST ACROSS SOUTHERN KANSAS AND OKLAHOMA PROVIDES ADDITIONAL LIFT. MCS TONIGHT SHOULD MOVE THROUGH SOUTHERN MISSOURI...SO WILL KEEP CHANCES LOW IN NORTHERN PART OF FORECAST AREA. DURING THE DAY ON WEDNESDAY...MCS EXITS MISSOURI...THEN WILL HAVE TO WAIT FOR NEXT MCS TO MOVE OUT OF NORTHERN PLAINS WEDNESDAY NIGHT AS ANOTHER SHORT WAVE MOVES THROUGH IN THE NORTHERN STREAM. WILL LEAVE THUNDERSTORMS THROUGHOUT FORECAST AREA DURING DAY ON THURSDAY AS SURFACE FRONT ASSOCIATED WITH THE NORTHERN STREAM WAVE SETTLES ACROSS FORECAST AREA. FOR TODAY...SHOULD SEE MORE CLOUDINESS SOUTH WITH DYING MCS...SO EXPECT WARMER TEMPERATURES IN NORTHERN HALF OF FORECAST AREA. THEN ON WEDNESDAY...850 TEMPERATURES JUMP UP INTO THE 18 DEGREE RANGE. SHOULD BE WARM ACROSS MOST OF THE FORECAST AREA ALTHOUGH A LITTLE LINGERING CLOUDINESS IN SOUTHEAST PART MAY HOLD TEMPS DOWN A FEW DEGREES. WILL NOT MAKE ANY SIGNIFICANT CHANGES TO FORECAST BEYOND THURSDAY TIMEFRAME. PC 950 PM... AM MAKING SOME CHANGES TO EXPECTED WEATHER FOR TONIGHT/TUESDAY. BASED UPON CURRENT SATELLITE/RADAR TRENDS AND 00Z MESOETA RUN BEST BET FOR THUNDERSTORMS TONIGHT WILL BE ACROSS NORTHERN HALF OF MO. CORFIDI VECTORS/THICKNESS CONTOURS INDICATE CENTRAL/NORTHEAST NE WILL TRACK NORTHEAST AND MOVE INTO NORTHWEST/NORTH CENTRAL MO AFTER MIDNIGHT. ACTIVITY PROGGED TO REACH THE MO RIVER AROUND 12Z. WILL LOWER POPS OVER SOUTHWESTERN COUNTIES TO CHANCE CATEGORY. HAVE ALSO INCREASED POPS OVER SOUTHERN 1/3 CWA FOR 12Z-16Z TIME FRAME ACROSS FAR SOUTHERN COUNTIES TO ACCOUNT FOR MCS MOVING THROUGH. STILL EXPECT REGENERATION OF AFTERNOON CONVECTION ACROSS ALL BUT FAR NORTHWEST MO TOMORROW. MJ 349 PM... MAIN FORECAST CONCENTRATION IN THE SHORT TERM IS ON THUNDERSTORM ACTIVITY OVER THE NEXT FEW DAYS. EARLY AFTERNOON SATELLITE IMAGERY AND SURFACE OBSERVATIONS DEPICT A SHORTWAVE TROUGH TRACKING OVER THE NORTHERN PLAINS REGION...WITH AN ASSOCIATED/STRENGTHENING SURFACE LOW STRADDLING THE SOUTH DAKOTA-NEBRASKA BORDER. ALSO SEEING THE BEGINNING STAGES OF THUNDERSTORM DEVELOPMENT ON VISIBLE IMAGERY IN EASTERN NEBRASKA. EXPECT THIS ACTIVITY TO INCREASE THIS AFTERNOON AND EVENING AS THE CAP WEAKENS...REACHING THE NORTHWEST CORNER OF MISSOURI BETWEEN 02Z AND 04Z. THUNDERSTORM ACTIVITY WILL GRADUALLY SPREAD ACROSS THE REMAINDER OF THE FORECAST AREA...ESPECIALLY AFTER 06Z...WHEN A 50-60KT LOW LEVEL JET BECOMES A KEY PLAYER...AND ISENTROPIC LIFT IS SUBSEQUENTLY MAXIMIZED. EXPECT THE THUNDERSTORMS TO CONGEAL INTO A MESOSCALE CONVECTIVE SYSTEM AROUND/AFTER 06Z. ALTHOUGH LAPSE RATES AND ELEVATED CAPE VALUES ARE SUFFICIENT TO SUPPORT LARGE HAIL...THINK THE MAIN THREAT WILL BE HEAVY RAIN. THIS IS SUPPORTED BY AN ETA-PROGGED MOISTURE CONVERGENCE BULLSEYE ON THE 310K ISENTROPIC SURFACE FORECAST TO BE SITUATED ALONG THE INTERSTATE 70 CORRIDOR BETWEEN 06Z AND 12Z TUESDAY. THERE IS ADDITIONAL SUPPORT FOR HEAVY RAINFALL WITH PRECIPITABLE WATER VALUES IN EXCESS OF 1.5 INCHES...850 DEWPOINTS AROUND 15 DEGREES CELSIUS...AND THE FACT THAT FLOW ALONG THE 310K ISENTROPIC SURFACE POINTS TOWARD AN AREA OF DIVERGENCE ASSOCIATED WITH THE ENTRANCE REGION OF THE UPPER LEVEL JET. EXPECT THE SYSTEM TO LOSE ITS OOMPH AS THE LOW LEVEL JET VEERS OFF TUESDAY MORNING...SO PRECIP SHOULD TAPER OFF BETWEEN 12Z AND 15Z. SHOULD THEN SEE A LATE MORNING/EARLY AFTERNOON BREAK IN THUNDERSTORMS. BUT IT WILL BE SHORT-LIVED...AS THE NEXT SEVERE THUNDERSTORM THREAT ARRIVES ON TUESDAY AFTERNOON...AS THE SURFACE COLD FRONT DRAPES ITSELF ACROSS THE FORECAST AREA. IN ADDITION...AN OUTFLOW BOUNDARY FROM THE MORNING CONVECTION WILL LIKELY PROVIDE AN ADDITIONAL FOCUSING MECHANISM FOR THUNDERSTORM DEVELOPMENT. ALTHOUGH THE ENVIRONMENT MAY INITIALLY BE CAPPED...CONVERGENCE ALONG SURFACE BOUNDARIES SHOULD ALLOW CONVECTION TO BE INITIATED. INITIALLY...LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY THREATS. THEN THE LOW LEVEL JET WILL GET CRANKING AGAIN AFTER 00Z...QUITE LIKELY RESULTING IN THE FORMATION OF ANOTHER MCS...WITH THE THREAT OF HEAVY RAIN ON TUESDAY EVENING/NIGHT. SCHMIT NO MAJOR CHANGES HAVE BEEN MADE TO THE EXTENDED PORTION OF THE FORECAST. DETAILS REGARDING SHOWER AND THUNDERSTORM ACTIVITY CONTINUE TO BE SKETCHY...DUE TO THE UNCERTAINTIES ASSOCIATED WITH TIMING OF SHORTWAVES SPEEDING THROUGH THE MID/UPPER WESTERLY FLOW. THE POSITION OF THE FRONTAL BOUNDARY PROGGED TO BE DRAPED ACROSS THE CENTRAL CONUS AND/OR ANY LINGERING OUTFLOW BOUNDARIES WILL ALSO COMPLICATE THE FORECAST. SO...WILL MAINTAIN LOW CHANCE POPS THURSDAY THROUGH SUNDAY UNTIL CONFIDENCE IMPROVES. TEMP-WISE...READINGS ARE EXPECTED TO BE NEAR CLIMATOLOGICALLY NORMAL VALUES. NRR .EAX... KS...NONE. MO...NONE.
