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.

COGILWhat 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 Des Moines, IA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 14, 6:44 PM CDT, 3 hours 46 minutes earlier.
Area forecast discussion, Jun 14, 6:44 PM CDT, 3 hours 46 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE DES MOINES IA 644 PM CDT TUE JUN 14 2011 ...UPDATED AVIATION DISCUSSION... .SHORT TERM /TONIGHT/... AREA OF LOW PRESSURE CONTINUES OVER NORTHEAST KS LATE THIS AFTERNOON. WARM FRONT HAS MADE IT INTO SOUTHERN IA AND TEMPS HAVE RISEN INTO THE LOWER 80S. MLCAPE NOW 500 TO 1500 ACROSS THE SOUTHWEST IN THE WARM SECTOR...BUT CAP CONTINUES FOR NOW. MUCAPE ALSO 500 TO 2000 ACROSS THE REGION WITH STORMS FIRING ALONG THE LEADING EDGE OVER NORTHERN AREAS. THOUGH THE MCS NOW OVER MN SHOULD REMAIN TIED TO THE SFC TROUGH THERE...SOME CONCERNS THAT IT COULD BUILD ESE WITH TIME IF COLD POOL GETS GOING. THIS WOULD AFFECT NORTHERN IA WITH HEAVIER RAINFALL. THIS WILL NEED TO BE WATCHED THROUGH THE EVENING. FARTHER SOUTH...IT WILL TAKE A FEW HOURS YET...22Z TO 01Z FOR CAP TO ERODE BUT CONVECTION THAT SHOULD DEVELOP ALONG THE COLD FRONT IN EASTERN KS WILL BEGIN TO MOVE EAST INTO THE WARM SECTOR AND ALONG THE WARM FRONT OVER SOUTHERN IOWA AND NORTHERN MISSOURI. ONE NOTICEABLE DIFFERENCE FROM LAST NIGHT IS THE H850 LOW LEVEL JET WHICH WILL SHIFT SLIGHTLY EAST LATER THIS EVENING AND FOCUS BEST MASS CONVERGENCE MORE EAST AND SOUTH OF THE AREA THAN LAST NIGHT. THIS MAY HELP KEEP THE HEAVIEST RAINFALL AWAY FROM AREAS THAT SAW THE WORST LAST NIGHT. LOWS TONIGHT WILL REMAIN IN THE UPPER 50S TO LOWER 60S OVER THE REGION. .LONG TERM /WEDNESDAY THROUGH TUESDAY/... SHORT WAVE WILL PULL EASTWARD WITH PRECIPITATION QUICKLY DIMINISHING ACROSS THE CWA EARLY WEDNESDAY. SURFACE HIGH PRESSURE WILL BUILD IN BELOW A WEAK UPPER LEVEL RIDGE FOR WEDNESDAY WHICH WILL ALLOW FOR A BRIEF DRY SPELL BEFORE A WET PATTERN SETS UP FOR EXTENDED. A WEAK SHORTWAVE WILL PUSH ACROSS RIDGE SPARKING CHANCES FOR SHOWERS AND THUNDERSTORMS THURSDAY...AND SURFACE LOW PRESSURE WILL DEVELOP IN SOUTHERN PLAINS. THIS WILL SET THE STAGE FOR ADDITIONAL OFF AND ON PRECIPITATION ACROSS CENTRAL IOWA THROUGHOUT THE REMAINDER OF THE PERIOD AS SHORTWAVES TRACK ACROSS RIDGE INTERACTING WITH FRONT ACROSS IOWA. EXPECT TO SEE A BREAK IN PRECIPITATION SUNDAY INTO MONDAY WITH LOW BEGINNING TO PULL NORTHWARD...BEFORE STRONG UPPER LEVEL LOW PUSHES EASTWARD ACROSS NORTHERN PLAINS...BREAKING UPPER LEVEL RIDGE LATE IN THE PERIOD. ONCE AGAIN HIGH RAINFALL TOTALS ARE LIKELY ACROSS THE REGION WITH THESE PERIODS OR RAIN...ESPECIALLY IN THUNDERSTORMS. TEMPERATURES WILL GRADUALLY WARM...AND WILL REMAIN SLIGHTLY ABOVE NORMAL. EXPECT WINDY CONDITIONS WEDNESDAY WITH GOOD DAYTIME MIXING. ..HYDROLOGY... BECAUSE OF THE UNCERTAINTY IN INITIATION AND EVOLUTION...THE FLASH FLOOD WATCH WILL BE CONTINUED DUE TO LOW FFG VALUES OVER MUCH OF SOUTHERN AND CENTRAL IOWA WHICH ARE CURRENTLY RUNNING AT 1 INCH OR LESS FOR ONE HOUR...AND 1 TO 2 INCHES FOR 3 HOUR VALUES. PWATS REMAIN IN THE 1.3 TO 1.5 INCH RANGE WHICH COULD BE CONVERTED INTO 1 TO 3 INCH RAINFALL AMOUNTS IN SOME OF THE STRONGER THUNDERSTORMS. && .AVIATION...15/00Z TAF FCST DOMINATED BY CONVECTION AND IFR/LOW MVFR CIGS ASSOCIATED WITH TROUGH APPROACHING FROM THE NW. FIRST ROUND OF TSTMS IS ALREADY MOVING ACROSS NRN IA WITH MORE STORMS JUST DEVELOPING OVER SRN IA PER LATEST RADAR IMAGERY...BUT WITH MOST STORMS JUST NOW INITIATING AND LOW CONFIDENCE IN TIMING DETAILS AT A GIVEN TERMINAL HAVE ONLY GONE WITH VCTS THIS EVE EXCEPT AT KMCW WHERE CLOSER PROXIMITY TO EXISTING STORMS WARRANTED HIGHER CONFIDENCE. IFR/LOW MVFR CIGS ACROSS NWRN IA WILL ALSO MOVE IN...ESP AT KFOD/KMCW...AND LIKELY AFFECT MOST OF THE TERMINALS BTWN 06Z AND 12Z. THERE SHOULD BE A BREAK OF A FEW HRS AFTER THE INITIAL STORMS...WITH MORE EXPECTED LATER TONIGHT. CONDITIONS WILL IMPROVE RAPIDLY AFTER ABOUT 12-15Z ON WED AS THE SYSTEM CLEARS TO THE EAST...WITH VFR EXPECTED THEREAFTER. && .DMX WATCHES/WARNINGS/ADVISORIES...
