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.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Kansas City, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 5, 3:31 PM CDT, 3 hours 19 minutes earlier.
Area forecast discussion, Aug 5, 3:31 PM CDT, 3 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 330 PAM CDT TUE AUG 5 2003 DEWPOINTS HAVE REACHED THE LOWER 70S FROM FALLS CITY THROUGH KANSAS CITY TO THE LAKE OF THE OZARKS. TEMPERATURES OVER NORTHEAST KANSAS HAVE REACHED THE MID 90S AND CUMULUS HAVE BEEN BUBBLING NORTH OF TOPEKA SINCE 18Z. A WEAK CONVERGENCE AXIS OVER EASTERN KANSAS WILL BE THE FOCUS FOR POTENTIAL INITIATION EARLY THIS EVENING. I DONT EXPECT ACTIVITY TO BE WIDESPREAD SINCE CONVERGENCE IS QUITE WEAK, BUT ANY STORMS THAT DO FORM WILL BE NASTY. DRY AIR IN THE MID LEVELS AND SURFACE DEWPOINT DEPRESSIONS NEAR 25F WILL CONTRIBUTE TO THE DAMAGING WIND THREAT. LARGE HAIL WILL ALSO BE LIKELY WITH FREEZING LEVELS WELL BELOW CLIMATOLOGY FOR AUGUST. STORMS THAT FORM NORTH OF TOPEKA HAVE THE POTENTIAL TO TRACK THROUGH KANSAS CITY TOWARD CLINTON THROUGH THIS EVENING. AFTER TONIGHTS POTENTIAL FOR STORMS, PRECIPITATION CHANCES OVER MOST OF THE AREA DECREASE SIGNIFICANTLY. RIDGING OVER THE NORTHERN HIGH PLAINS AND MID LEVEL WARMING WILL CUT DOWN ON AVAILABLE INSTABILITY. 700MB TEMPERATURES REMAIN RELATIVELY LOW OVER THE EASTERN HALF OF MISSOURI, SO ILL RETAIN A 20 TO 30 PERCENT CHANCE OF STORMS TOMORROW AFTERNOON FOR KIRKSVILLE, SEDALIA AND MOBERLY. NORTHERLY FLOW IS PROJECTED TO INCREASE ON THURSDAY AS HIGH PRESSURE BUILDS IN FROM THE UPPER MIDWEST DROPPING DEWPOINTS AND TEMPERATURES BY A FEW DEGREES. KOCH MEDIUM RANGE MODELS CONTINUE PREVIOUS TREND OF KEEPING FORECAST AREA IN NORTHWEST FLOW ALOFT AND BETWEEN UPPER TROF TO THE EAST AND UPPER LEVEL RIDGE OVER THE HIGH PLAINS...IN ESSENCE IN NO MANS LAND...INTO SATURDAY. GFS PROGS A SHORTWAVE DROPPING SOUTHEAST OVER TOP OF UPPER RIDGE LATE FRIDAY NIGHT/SATURDAY WHICH COULD BRING MUCH NEEDED RAIN TO REGION. HOWEVER...TOO MUCH UNCERTAINTY ON TRACK AND HARD TO BREAK THE BACK OF A LONG DRY SPELL ONCE IT GETS TO THIS STAGE UNLESS AN MCS TYPE SYSTEM CAN MOVE THROUGH. TILL THEN WILL KEEP FORECAST DRY AND BRING WARMER/MORE HUMID AIR BACK INTO THE CWA FOR THE WEEKEND. TEMPERATURES WILL BE ABOVE GUIDANCE AS 850 MB FLOW GOES SOUTHWESTERLY WITH SURFACE RIDGE RETREATING TO THE EAST. MJ 1000 AM TUE... AN UPDATE TO THE FORECAST HAS BEEN ISSUED FOR THE TODAY AND TONIGHT TIME FRAMES. REMNANTS OF LAST NIGHTS NOCTURNAL CONVECTION OVER EASTERN NEBRASKA FAILED TO HOLD TOGETHER AS IT TRACKED SOUTHEAST. WITH LIMITED INSTABILITY EXPECTED THIS AFTERNOON OVER NORTH CENTRAL AND NORTHEAST MISSOURI AND A LACK OF A SURFACE FEATURE TO ACT AS A FOCUS, THUNDERSTORMS SEEM UNLIKELY. BETTER INSTABILITY WILL BE ORIENTED FROM TOPEKA TO SPRINGFIELD WHERE MID 60S TO LOWER 70S DEWPOINTS RESIDE. LOTS OF SUNSHINE THIS AFTERNOON WILL YIELD CAPE VALUES IN THE 2000 TO 3000 J/KG RANGE AND SURFACE CHARTS DEPICT A WEAK SURFACE TROUGH OVER EASTERN KANSAS. I EXPECT WIDELY SCATTERED STORMS THIS AFTERNOON THROUGH THIS EVENING FROM SOUTH OF TOPEKA TO SPRINGFIELD AND A FEW OF THESE STORMS MAY GLANCE LINN, MIAMI AND BATES COUNTIES. GIVEN THE DEGREE OF INSTABILITY AND SHEAR A FEW OF THESE STORMS COULD PRODUCE LARGE HAIL AND DAMAGING WIND GUSTS. KOCH 422 AM TUE... CONCENTRATED ON PRECIP CHANCES THROUGH THE NEXT FEW DAYS. THUNDERSTORMS ASSOCIATED WITH NOSE OF THE LOW LEVEL JET AND THETA-E AXIS ACROSS SOUTHEAST KANSAS AND SOUTHWEST MISSOURI SHOULD CONTINUE TO DIMINISH IN COVERAGE AND INTENSITY AS THE JET CONTINUES TO VEER. WOULD EXPECT ONLY PRECIP IN THE FORECAST AREA TO BE OVER THE EXTREME SOUTHWEST PORTION EARLY THIS MORNING. IN ADDITION...SHORTWAVE MOVING ACROSS EASTERN NEBRASKA AND IOWA HAS A LARGE AREA OF THUNDERSTORMS ASSOCIATED WITH IT. IR SATELLITE LOOP SHOWS TOPS WARMING...SO EXPECT THIS AREA TO ALSO WEAKEN IN INTENSITY AND BECOME LESS WIDESPREAD. THIS IS BACKED UP BY RADAR MOSAIC. NORTHERN SECTIONS OF THE FORECAST AREA SHOULD SEE SCATTERED SHOWERS AND THUNDERSTORMS THIS MORNING. EXPECT VERY LITTLE PRECIP ACROSS THE REGION BY LATE MORNING. THIS SHOULD ALLOW THE ATMOSPHERE TO DESTABILIZE SOME FOR THE AFTERNOON. SOUNDINGS SHOW LITTLE IF ANY CAP TO BE IN PLACE. SHORTWAVE SHOULD ALSO BE MOVING ACROSS THE SOUTHERN AND EASTERN PORTIONS OF THE REGION AT THAT TIME. ANY LINGERING BOUNDARIES MAY BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT...ESPECIALLY SOUTH AND EAST OF THE KANSAS CITY METRO AREA. HIGHEST CAPE(>1500) IS FOUND ACROSS MAINLY SOUTHERN MISSOURI. EXPECT ANY SEVERE WEATHER TO BE IN THAT AREA. HOWEVER CANNOT RULE OUT AN ISOLATED SEVERE STORM ACROSS EAST CENTRAL KANSAS INTO WEST CENTRAL MISSOURI...SOUTH OF THE KANSAS CITY METRO AREA. SOUNDINGS ALSO SHOW NO CAP IN PLACE ACROSS THE AREA FOR WEDNESDAY. FOR NOW HAVE PUT 30 POPS IN FOR ONLY THE EASTERN SECTION OF THE FORECAST AREA...AND A SLIGHT CHANCE IN FOR CENTRAL MISSOURI. GFS IS STARTING TO SHOW ANOTHER DECENT SHORTWAVE MOVING ACROSS THE REGION FRIDAY INTO SATURDAY. HAVE LEFT PRECIP OUT OF THE FORECAST FOR NOW...PENDING CONSISTENT MODEL RUNS. NRR .EAX... KS...NONE. MO...NONE.
