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
Aberdeen, SD (KABR), launched 12:00Z, 11.2 hours before the alert went out and 227 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.

Area forecast discussion, May 26, 4:10 PM CDT, 1 hour 59 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 410 PM CDT WED MAY 26 2004 .DISCUSSION... SEVERAL PRECIPITATION CHANCES OVER THE NEXT SEVERAL DAYS ACROSS THE CWA. FOR TONIGHT...CONVECTION IS EXPECTED TO BREAK OUT BY 23Z ALONG A CONVERGENCE LINE IN CENTRAL SD. AS NOTED BY SPC...SOME HAIL IS POSSIBLE WITH CELLS...ESP NORTH OF INTERSTATE 90 DUE TO VERY COLD MID LEVELS. SOME HAIL LARGER THAN AN INCH COULD BE POSSIBLE AS SHEAR VALUES OVER 40 KTS MAY SUPPORT ROTATING CELLS THIS EVENING. OTHERWISE..TROF WILL ROLL THROUGH BY MIDNIGHT ENDING THE CHANCE FOR CONVECTION SHORTLY AFTER MIDNIGHT. THE SEVERE THREAT SHOULD END WITH HEATING BY 10 OR 11 PM. THEN A BACKDOOR FRONT WILL APPROACH SW MN TOWARD DAWN. THE BACKDOOR FRONT WILL MOVE THROUGH DURING THE MORNING. STALLING NEAR THE SRN END OF THE CWA. STRONG COLD ADVECTION AND MOSTLY CLOUDY SKIES WILL FOLLOW THE FRONT. THIS WILL RESULT IN A STRONG TEMPERATURE GRADIENT WITH NEAR 80 IN THE SOUTH CENTRAL WHILE MID 60S ARE LIKELY AROUND MARSHALL WITH NORTH TO NORTHEAST FLOW. OTHERWISE NO PRECIPITATION EXPECTED. ON THU NIGHT...SFC HIGH WILL MOVE NORTH OF THE CWA. WITH THE RIDGING IN THE EAST...WINDS WILL BECOME LIGHT ALLOWING TEMPS TO FALL INTO THE 40S IN THE NE CWA. IN THE WRN CWA...SELY FLOW WILL INCREASE AS WELL AS SKIES BECOMING PARTLY CLOUDY. THIS WILL KEEP TEMPS AROUND 60. ON FRIDAY...WINDS WILL INCREASE RAPIDLY DURING THE DAY AS THE LLJ INCREASES OVER THE CWA. THIS WILL ALSO MEAN A RAPID INCREASE IN DEW POINTS. THEN...AS CYCLOGENESIS COMMENCES IN WRN SD...A WARM FRONT SHOULD FORM AROUND I90. WHILE CONVERGENCE WILL INCREASE SO WILL MID-LEVEL TEMPS HELPING TO CAP THE ATMOSPHERE OVER THE WRN CAW. EXPECT THAT IF CONVECTION DEVELOPS IT WILL BE LATE AFTERNOON ALONG THE WARM FRONT IN THE K9V9 AND KHON AREA AND A WEAK UPPER WAVE APPROACHES. THERE IS ENOUGH SHEAR THAT IF STORMS DEVELOP THERE COULD BE AN ISOLATED SEVERE REPORT. THE CHANCE FOR TSRA WILL END DURING THE EVENING IN THE NW CWA BUT FRONT HANGS CLOSE ENOUGH TO THE NRN CWA TO WARRANT A SLIGHT CHANCE FROM BKX TO MML AREA. ON SATURDAY...THE FRONT WILL APPROACH LATE IN THE DAY. HAVE FOLLOWED THE ETA FOR THE FRONTAL PROPAGATION ON SATURDAY. WILL CONTINUE THE CHANCE FOR CONVECTION LATE. SHEAR IS NOT QUITE AS IMPRESSIVE IN THE 3-6 KM LAYER BUT STRONG LEAD WAVE SHOULD HELP IGNITE CONVECTION ALONG THE COLD FRONT DURING THE AFTERNOON. THE BEST CHANCE OF WILL BE IN THE EVENING IN THE WRN CWA...SHIFTING INTO THE NRN CWA TOWARD SUNSET. AGAIN SEVERE WEATHER WILL BE POSSIBLE...LIKELY EARLY IN THE EVENT. THEN IT COULD TRANSITION INTO HEAVY RAIN AS TRAINING IS LIKELY AHEAD OF THE FRONT. IN THE EXTENDED...FEEL THE GFS IS WAY TOO FAST IS CRASHING THE RIDGE TOO QUICKLY ON SUNDAY. THEREFORE EXPECT FROPA TO BE SUNDAY MORNING IN THE WEST AND SUNDAY EVENING IN THE ERN CWA. NW IA COULD EVEN DRY SLOT AS THE CYCLONE MOVES NORTHEAST DURING THE DAY. THE BEST CHANCE FOR PRECIPITATION LOOKS TO BE IN SW MN AHEAD OF THE COLD FRONT DURING THE AFTERNOON AND EVENING. THEN..AS FRONT MOVES TO THE EAST...EXPECT THAT PRECIPITATION WILL WRAP AROUND AS UPPER WAVE MOVES NORTHEAST AND BECOMES NEGATIVELY TILTED. THUS KEPT A CHANCE OF RAIN IN SUNDAY AND MONDAY AS WELL. WITH CLOUDS AND 850 MB TEMPS BELOW 10C...EXPECT TEMPS IN THE 60S. IF CLOUDS ARE THICKER THAN EXPECTED...TEMPS MAY NOT EVEN BREAK 60. CONVECTIVE SHOWERS MAY AGAIN OCCUR ON TUES IN THE ERN 2/3 OF THE CWA. THEN EXPECT THE UPPER LOW TO MOVE EAST ON WEDNESDAY ALLOWING MORE SEASONAL TEMPS AND PARTLY CLOUDY SKIES INTO THE AREA. && .FSD...WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE.
