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.

SEAMANWhat 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 Jul 13, 2:25 PM CDT, 5 hours 19 minutes earlier.
Area forecast discussion, Jul 13, 2:25 PM CDT, 5 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 225 PM CDT TUE JUL 13 2004 .DISCUSSION... FIRST ITEM OF IMPORTANCE IS THE HEAT ADVISORY THAT REMAINS IN EFFECT FOR PART OF THE WESTERN FORECAST AREA. WILL LET THE ADVISORY EXPIRE AS PLANNED AT 7 PM. MAIN FORECAST CONCERN IN THE NEXT SEVERAL DAYS IS PRECIPITATION CHANCES. WITH THE UPPER LEVEL RIDGE LOCATED OVER THE WESTERN U.S...THE FORECAST AREA WILL REMAIN UNDER THE NORTHWEST FLOW REGIME. AT THE SURFACE...A COLD FRONT IS CURRENTLY DRAPED FROM NORTHEAST MISSOURI SOUTHWESTWARD ACROSS NORTHERN MISSOURI INTO EXTREME NORTHEAST KANSAS. RADAR ECHOES HAVE BEEN NOTED THROUGHOUT THE DAY BEHIND THE FRONT ACROSS EASTERN NEBRASKA AND SOUTHERN IOWA. AS THE FRONT PUSHES SOUTH TONIGHT...THERE WILL BE THE CHANCE FOR SHOWER AND THUNDERSTORM DEVELOPMENT AS FALLING THICKNESSES WILL RESULT IN A LESS STABLE AIRMASS. A SLIGHTLY CURVED 250MB JET WILL ADVANCE SOUTHEAST...AND PROVIDE SOME UPPER LEVEL DIFFLUENCE OVERNIGHT. THE LIMITING FACTOR MAY BE THE STRENGTH OF THE CAP. WILL RETAIN THE LOW END CHANCES FOR PRECIPITATION WITHIN THE BAROCLINIC ZONE TONIGHT...MAINLY NORTH OF INTERSTATE 70. THE FRONT IS EXPECTED TO PUSH SOUTH OF THE FORECAST AREA BY WEDNESDAY MORNING...PROVIDING RELIEF FROM THE HOT AND HUMID CONDITIONS. THE NEXT POSSIBILITY FOR PRECIPITATION IS WEDNESDAY NIGHT. THE LOW LEVEL JET BECOMES ESTABLISHED ACROSS WESTERN KANSAS AS A SHORTWAVE ADVANCES SOUTHEAST NEAR THE KANSAS/MISSOURI BORDER. THE GFS AND ETA DIFFER WITH THE STRENGTH OF THE SHORTWAVE...WITH THE GFS MUCH STRONGER. QUESTION REMAINS AS TO HOW FAR WEST THE LOW LEVEL JET WILL SET UP. DID NOT GO HIGHER THAN SLIGHT CHANCES ACROSS WESTERN SECTIONS DUE TO THE REMAINING UNCERTAINTY WHETHER PRECIPITATION WILL DEVELOP FAR ENOUGH EAST. STOFLET FROM FRIDAY INTO THE WEEKEND...THE WESTERN CONUS RIDGE IS FORECAST TO CONTINUE BREAKING DOWN...YIELDING A NORTHWESTERLY FLOW REGIME OVER THE FORECAST AREA. IT IS COMPLICATED TO PIN DOWN SHORTWAVES TOPPING THE NORTHERN PERIPHERY OF THE RIDGE...AND RUN-TO-RUN MODEL CONSISTENCY REGARDING THE TEMPORAL/SPATIAL CHARACTERISTICS OF THESE FEATURES HAS BEEN POOR. WILL MAINTAIN SLIGHT CHANCE POPS ON FRIDAY DUE TO THIS UNCERTAINTY. WILL LEAVE 20-30 POPS IN ON SATURDAY...AS THE 00Z AND 06Z GFS SOLUTIONS FORECASTED THE ARRIVAL OF A SHORTWAVE AND ASSOCIATED FRONT ACROSS THE FORECAST AREA. WILL NOT INCREASE POPS AT THIS POINT...AS THE 12Z GFS DID NOT KEY IN ON THIS FEATURE. NO CHANGES WERE MADE TO TEMPS...WITH NEAR-NORMAL READINGS EXPECTED TO PREVAIL THROUGH THE EXTENDED PERIOD. SCHMIT && .PREV DISCUSSION... 335 AM TUE... TEMPERATURES IN THE SHORT TERM AND PRECIP CHANCES THROUGHOUT ARE THE MAIN CHALLENGES THIS MORNING. JUST MISSED OUT ON CONVECTION TONIGHT...STORMS RAN INTO A WALL AS THEY GOT INTO NORTHERN MO. NICE LEFTOVER ANVIL WILL BE SHIFTING OUT OF HERE THIS MORNING...WHICH SHOULD NOT AFFECT TEMPERATURES AT ALL. ALSO LEFT BEHIND IS AN OUTFLOW BOUNDARY IN NORTHERN MO. MID LEVEL TEMPERATURES HAVE WARMED SIGNIFICANTLY OVERNIGHT...SO THE OUTFLOW BOUNDARY IS NOT A CONCERN FOR THE MORNING. HOWEVER...THE FRONT PROGGED TO GO THROUGH THIS AFTERNOON WILL BE SOMETHING TO WATCH FOR. CONVERGENCE ALONG IT IS WEAK...BUT AS THE FRONT GETS INTO NORTH CENTRAL AND NORTHEAST MO THE CAP IS WEAKER. WITH HIGH INSTABILITIES AND AN SPC MODERATE RISK...HAVE INTRODUCED CHANCE POPS IN NORTHEAST CWA FOR THIS AFTERNOON. IF STORMS FIRE...THEY WILL QUICKLY BECOME SEVERE...AND EXIT JUST AS FAST. THERE SHOULD BE A LULL IN THE EVENING...BUT THE MODELS HAVE BEEN CONSISTENT IN GENERATING STORMS AFTER MIDNIGHT. THESE STORMS TRACK ALONG THE BOUNDARY OVERNIGHT...AND WORK BACK INTO THE NORTHWESTERN CORNER OF THE CWA. HAVE CONTINUED LOW CHANCE POPS FOR THIS MAINLY AFTER MIDNIGHT. THROUGH THE REMAINDER OF THE WEEK...A BACKDOOR FRONT REMAINS NEARBY WITH NORTHWEST FLOW ALOFT AND SEVERAL SHORTWAVES ROTATING THROUGH. HAVE NOT ALTERED POPS MUCH...AS GOING FORECAST HAS AS GOOD A HANDLE ON IT AS CAN BE EXPECTED. DEWPOINTS SHOULD REMAIN IN THE MID 70S TODAY. MAY BE ABLE TO MIX DOWN A DEGREE LESS HERE AND THERE...BUT HEAT INDICES WILL BE HIGH AGAIN TODAY. KMCI INDEX GOT AS HIGH AS 108 YESTERDAY...BUT WAS THE ONLY SITE TO REACH HEAT ADVISORY CRITERIA. SOUTHWEST WINDS TODAY ARE USUALLY GOOD FOR US TO WARM UP...SO HAVE KEPT THE UPPER 90S IN THE WESTERN COUNTIES. HOWEVER WITH THE HIGHER DEWPOINTS EXPECTED... HAVE LOWERED THE EASTERN CWA FROM UPPER TO MID 90S FOR HIGHS TODAY. THIS IS 4-5 DEG WARMER THAN YESTERDAY. WILL GO AHEAD AND HOIST A HEAT ADVISORY AGAIN TODAY...WILL GO FROM THE KANSAS CITY METRO NORTH TO KSTJ...AND SPREAD EAST A FEW MORE ROWS OF COUNTIES. WITH THE BOUNDARY AROUND THE REMAINDER OF THE WEEK...THERMAL RIDGE GETS PUSHED WEST...SO THIS SHOULD BE THE LAST TERRIBLY HOT DAY THIS WEEK. 27 1003 PM MON... DID A QUICK UPDATED TO NORTHERN COUNTIES TO HANDLE STORMS COMING SOUTH OUT OF IOWA AND NEBRASKA. LATEST ANALYSIS SHOWING INCREASING INSTABILITY AXIS COMING DOWN THE MISSOURI RIVER VALLEY INTO NORTHWEST MISSOURI...AND CURRENT TRACK OF STORM NEAR OMAHA WOULD HAVE IT CROSSING BORDER INTO MISSOURI AFTER 11 PM. RUC SHOWS CAP IS STRENGTHENING INTO NORTHWEST CORNER OF MISSOURI AFTER MIDNIGHT...SO MAY FORCE STORMS FURTHER EAST...SO WILL ADD POPS INTO NORTH CENTRAL MISSOURI FOR LATER TONIGHT.
