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.

The nearest sounding before it
Aberdeen, SD (KABR), launched 12:00Z, 2.4 hours before the alert went out and 30 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.

MAIN FOCUS FOR SHORT TERM FORECAST REVOLVES AROUND TIMING PCPN TODAY...THEN DEALING WITH PCPN CHCS FOR FAR SWRN CWA MID WEEK. LOLVL JET ACROSS CENTRAL SODAK HAS FIRED OFF AREA OF ELEVATED TSRA FROM KABR AND AREAS WEST. NOTHING IS REALLY ORGANIZED WITH CONVECTION...AND ALTHO SOME DECENT RAINERS ARE EMBEDDED WITHIN THE AREA...MOVEMENT IS SUCH THAT FLOODING RAINS NOT VERY LIKELY. WILL CANCEL FLOOD WATCH WITH ZONE ISSUANCE. FOR LATER TODAY...COLD FRONT SLOWLY PASSES EAST THROUGH CWA...WITH MODELS NOW PROGGING A SLIGHTLY SLOWER PASSAGE THAN PREVIOUSLY SEEN. WITH SCATTERED BOUNDARIES FROM THIS MORNINGS CONVECTION...AND BETTER RESOLUTION OF SECOND 5H WAVE PASSING THROUGH NERN CWA BY 00Z TUESDAY...EXPECT SCT TSRA TO AGAIN DEVELOP LATER THIS AFTN...BASICALLY ALONG THE I-29 CORRIDOR AND EAST. FOR THE REMAINDER OF THE NEAR TERM...THINGS QUIET DOWN SOMEWHAT. WITH CLOSED 5H VORTEX FLATTENING 5H RIDGE OVER CWA TODAY...RIDGE REBOUNDS BACK TO THE WEST OF CWA...WITH CWA IN NW FLOW ALOFT. COLD FRONT SAGS THROUGH CWA BY 12Z TUESDAY...WITH CANADIAN HIGH NOSING INTO NERN CWA. ONE PROBLEM AREA IS WITH WESTERN EDGE OF FRONTAL BOUNDARY BEGINNING TO LIFT SLOWLY TO THE NORTH...BECOMING DRAPED ACROSS SWRN SODAK BY 12Z WEDNESDAY. THERE IS ENOUGH 7H AND 85H THETA-E FORCING TO WARRANT A SLIGHT CHC TSRA TUESDAY NIGHT ACROSS FAR SW CWA. OTW LOOKS TO BE DRY AND SEASONABLE THROUGH 12Z THURSDAY. .LONG TERM...12Z THURSDAY THROUGH SUNDAY. EXTENDED STARTS OFF WITH CONTINUATION OF 5H RIDGE POSITIONED WEST OF CWA WITH DRY NOW FLOW ALOFT. PROBLEM STILL LOOKS TO BE FRIDAY EVENING/NIGHT AS GFS CONTS TO SHOW 7H TROF MOVING THROUGH ERN CWA 00Z SAT-12Z SATURDAY. WEAK 5H WAVE DROPS QUICKLY DOWN BACKSIDE OF 5H RIDGE...WITH 85H FRONT DRAPED E-W ACROSS CWA BY 12Z SATURDAY. THINK THAT MOST OF PCPN WILL BE ACROSS ERN CWA...SO HAVE REMOVED WESTERN SECTIONS FROM PCPN MENTION. NOT SURE THAT PCPN WILL ALSO LAST AS LONG AS WE CURRENTLY ARE FCSTING...BUT LEFT ALONE FOR CONTINUITY SAKE. REMAINDER OF EXTENDED FORECAST LOOKS TO BE DRY. && .ABR WATCHES/WARNINGS/ADVISORIES...
