A strong low pressure system resulted in a northward push of warmth and moisture into the mid-upper Missouri River Basin during the late afternoon and evening of April 12th. Ample 0 to 6 km shear of 60 to 70 kts, combined with MLCAPE values of 1000-2500 J/kg resulted in a prime environment for severe thunderstorms. Severe hail averaging in size from quarters to ping-pong balls fell across portions of southeast South Dakota, southwest Minnesota, and northwest Iowa. Another cold front-induced line of convection developed later in the evening across eastern Nebraska and northwest Iowa, with the primary threat being damaging winds.
More widespread synoptic high winds followed the passage of a strong cold front. Peak wind gusts in excess of 58 mph occurred across much of southeast South Dakota and into portions of northwest Iowa.
