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
Springfield, MO (KSGF), launched 12:00Z, 10.0 hours before the alert went out and 144 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.

MCGUIREWhat 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 Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 12, 3:06 PM CDT, 1 hour 56 minutes earlier.
Area forecast discussion, Jul 12, 3:06 PM CDT, 1 hour 56 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 306 PM CDT TUE JUL 12 2011 .DISCUSSION... MAIN FORECAST CONCERNS ARE CONVECTIVE TRENDS FOR THE FIRST COUPLE OF PERIODS WITH ATTENTION TURNING BACK TO THE HEAT THROUGH THE BEGINNING OF NEXT WEEK. SYNOPSIS: IN THE UPPER LEVELS WE CURRENTLY HAVE A SHORTWAVE TROUGH APPROACHING THE PACIFIC NW WITH ADDITIONAL ENERGY SLIDING OVER SOUTHERN ONTARIO. MEANWHILE THE FEATURE THAT WILL DIRECTLY IMPACT OUR AREA WILL BE THE SLOW MOVING TROPICAL-LIKE WAVE THAT IS SITUATED OVER NW OKLAHOMA. AT THE SURFACE A COLD FRONT STRETCHES FROM NORTHERN MO INTO WEST-CENTRAL KS. TONIGHT-WED: THESE TWO PERIODS WILL HAVE THE "BEST" CONVECTIVE CHANCES THROUGH THIS FORECAST PACKAGE AS THE UPPER CIRCULATION CONTINUES TO MAKE ITS WAY EAST. IN THE WEAKLY CAPPED ENVIRONMENT STORMS DEVELOPED THIS AFTERNOON OVER EASTERN KS WHERE BETTER LOW LEVEL MOISTURE RESULTED IN HIGHER INSTABILITY. FEEL ANOTHER AREA OF MORE ORGANIZED CONVECTION WILL BE ALONG THE FRONT OVER WEST-CENTRAL KS. CURRENT THINKING IS THAT DIURNALLY DRIVEN PRECIP WILL PROVIDE THE MOST COVERAGE AND WILL THEREFORE HOLD ONTO THE HIGHEST PRECIP CHANCES THROUGH THE EVENING HOURS. BY WED AFTERNOON THE UPPER IMPULSE WILL BE LOCATED OVER FAR EASTERN KS/EASTERN OK. THIS FEATURE WILL CONTINUE TO RESULT IN WEAK AFTERNOON CAPPING. HOWEVER THE BETTER SURFACE FOCUS FOR MORE ORGANIZED CONVECTION WILL BE PUSHED EAST OF WHERE IT IS TODAY RESULTING IN FAR EASTERN KS AND MO HAVING THE BETTER PRECIP CHANCES. AT THE SAME TIME ADDITIONAL UPPER ENERGY IS EXPECTED TO LIFT OUT OF THE CENTRAL ROCKIES AND INTO THE NORTHERN HIGH PLAINS BY WED AFTERNOON...RESULTING IN ADDITIONAL CONVECTION OVER WESTERN NE/NW KS. WITH SOME LINGERING CLOUD OVER ASSOCIATED WITH THE UPPER IMPULSE...TEMPS ON WED WILL LIKELY BE THE COOLEST THROUGH THE NEXT 7 DAYS AS THEY TOP OUT IN THE MID TO UPPER 90S. THU-TUE: THE MAIN THEME THROUGH THESE PERIODS WILL BE A STRENGTHENING RIDGE OVER THE SOUTHERN PLAINS WHICH WILL BRING A RETURN TO THE INTENSE HEAT. GIVEN THE INTENSE HEAT THERE WILL BE A CHANCE FOR A LATE AFTERNOON STRAY STORM EACH DAY...HOWEVER COVERAGE IS NOT EXPECTED TO BE HIGH ENOUGH TO MENTION IN THE FORECAST AT THIS TIME. BY FRI IT IS LIKELY WE WILL BE BACK INTO THE HEAT HEADLINE BUSINESS FOR MUCH OF THE AREA. LAWSON && .AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU WEAK UPPER LOW CIRCULATING OVER FAR NORTHWESTERN OKLAHOMA EARLY THIS AFTERNOON...WILL DRIFT EAST-NORTHEASTWARD ACROSS SOUTH CENTRAL AND SOUTHEASTERN KANSAS TONIGHT INTO WEDNESDAY MORNING. WEAK FORCING FROM THE UPPER LOW SHOULD GENERATE SCATTERED SHOWERS/T-STORMS THIS PM/EVE ESPECIALLY OVER SOUTHEAST KS WHERE THE BETTER INSTABILITY IS. GUSTY WINDS POSSIBLE NEAR ANY STORMS GIVEN HIGH TEMPERATURE-DEWPOINT SPREADS BELOW CLOUD BASE. FOR NOW...HAVE UTILIZED VCTS AT MOST SITES TO ACCOUNT FOR ISOLATED- SCATTERED ECHOES. OTHERWISE VFR CONDITIONS TO PREVAIL OUTSIDE ANY STORMS. JMC && .PRELIMINARY POINT TEMPS/POPS...
