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
Minneapolis, MN (KMPX), launched 00:00Z, 5.1 hours before the alert went out and 228 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.

AS FBY PROF TAKING ON MUCH MORE CLASSIC WAA LOOK AND LLJ CONTINUES TO INCRS THRU PLAINS. WAVE COMING THRU MEAN RIDGE IS NOT STRONG... BUT IS AT LEAST CONTRIBUTING WEAK SUPPORT TO DEVELOPMENT OF PCPN. LIKE LOOK OF RUC MUCH BETTER THAN ERLR 18Z NAM...AND WL USE FRONTAL DYNAMICS AND ELEVATED THETA-E ADVECTION TO TIE PCPN DISTRIBUTION. APPEARS MOST FAVORABLE AREA FOR PCPN WL BE HEADING IN 06Z-08Z TIMEFRAME FM KFSD TOWARD KSLB...THEN SHIFTING EWRD AND NEWRD THE REMAINDER OF THE NIGHT. SEVERE THREAT WL CONTINUE WITH LARGE HAIL...BUT WKNS OF MID LVL FLOW WL MEAN ROTATING STORMS WL NOT HAVE A LONG LIFETIME...AND WL LIMIT POTENTIAL HAIL SIZE LKLY TO ARND QUARTERS IN STRONGER STORMS. ACTION FARTHER TO THE W IS LKLY TO REMAIN MOSTLY W OF THE AREA OVERNIGHT AS PROPOGATION VECTORS DO NOT GIVE MUCH OF A CHANCE TO AFFECT ANY BUT FAR WRN CWA AFTER MIDNIGHT FOR A COUPLE HOURS. RAISED LOW TMPS SEVERAL DEGREES...BUT DID NOT WANT TO GET TOO OUT OF HAND AS WET BULBING COULD TAKE TMPS DOWN QUITE EFFICIENTLY WHEN ORGANIZED PCPN GETS GOING. UPDATED GRIDS/PFM SENT...ZFP SHORTLY. && .PREV DISCUSSION... 259 PM CDT FRI MAY 6 2005 VERY BUSY FORECAST OVER THE NEXT SEVERAL DAYS...AND MOST LOCATIONS SHOULD SEE SOME DECENT RAINFALL OVER BETWEEN NOW AND NEXT THURSDAY. FOR TONIGHT...WARM FRONT JUST SOUTH OF THE MO RIVER AT 19Z...WITH SOME WEAK CONVECTION FIRING OVER SOUTH CENTRAL SD. LOTS OF ENERGY UPSTREAM...WITH ONE PIECE OF ENERGY MOVING INTO SW NE AND THE MAIN WAVE MOVING INTO THE FOUR CORNERS REGION. WILL HAVE TO WATCH THE NE CO SW NE REGION FOR DEVELOPMENT THIS AFTERNOON...WHICH SHOULD LIFT NORTHEAST INTO OUR AREA TONIGHT. WILL GO FAIRLY HIGH POPS WITH A WIDESPREAD QUARTER TO HALF AN INCH OF RAINFALL ANTICIPATED. SEVERE THREAT IS ALSO THERE FOR LATE AFTERNOON AND TONIGHT WITH MAIN THREATS BEING HAIL...SOME OF IT POSSIBLY UP TO QUARTER OR HALF DOLLAR SIZED WITH SUPPORTIVE WIND SHEAR. INSTABILITY ONLY MARGINAL HOWEVER. SATURDAY DURING THE DAY SHOULD END UP BEING FAIRLY QUIET...BUT A KINK IN THE MID LEVELS MAY BE ENOUGH TO SPARK SOME THUNDERSTORM ACTIVITY. WILL CONTINUE CHANCE CATEGORY POPS. MAIN WAVE AND FRONT START TO MAKE MORE OF A PUSH ON SUNDAY AND WILL AGAIN SEE A THREAT FOR CONVECTION. BOTH SATURDAY NIGHT AND SUNDAY WILL SEE DECENT CHANCES AT SEVERE WEATHER. FOR WEDNESDAY THROUGH FRIDAY...STILL LOOKING LIKE A WET PATTERN AND HAVE BUMPED POPS TO 50 TO 60 FOR THE ENTIRE AREA WEDNESDAY INTO THURSDAY. THE 00Z-12Z GFS AND CANADIAN AS WELL AS ENSEMBLES ALL POINT TOWARDS A LARGE WAVE WITH A STRONG WARM FRONT/INVERTED TROF LATE TUESDAY THROUGH THURSDAY. OBVIOUSLY...AT THIS RANGE...TIMING IS A LITTLE DIFFERENT BETWEEN EACH MODEL AND INDIVIDUAL RUN...BUT SEEMS LIKE IT WOULD BE PRETTY TOUGH NOT TO GET SOMETHING WEDNESDAY NIGHT INTO THURSDAY. RIGHT NOW...JUST FAR ENOUGH NORTH AND WEST OF WARM FRONT/INVERTED TROUGH THAT SEVERE WEATHER NOT VERY LIKELY. BUT...IF WARM FRONT COMES OUT ABOUT 100 MILES FARTHER NORTH...IT WOULD BE MUCH MORE HECTIC AND MUCH WARMER OVER THE SOUTHERN CWA. WILL KEEP TEMPERATURES ON THE COOL SIDE THURSDAY AND FRIDAY AS WAVE MOVE OVERHEAD AND PAST US. WE COULD SEE SOME VERY HEAVY RAINFALL FROM LATE TUESDAY INTO THURSDAY AS THIS ENERGY PASSES AND WILL BE SOMETHING TO HIGHLIGHT AND WATCH OUT FOR THE NEXT SEVERAL DAYS. 08 && .FSD WATCHES/WARNINGS/ADVISORIES...
