What happened
The episode as NWS OAX wrote it up.
A seasonably strong upper level storm system swept across the northern Plains during the day on Sunday August 31st. Ahead of the storm system low pressure developed over the high Plains and allowed for warm and moist air to pool over the mid Missouri River Valley creating strong instability by mid to late afternoon. As a cold front and associated upper level jet streak interacted with the instability, thunderstorms developed from northeast Nebraska into Northern Kansas. These thunderstorms moved east through the rest of the afternoon and evening hours, crossing eastern Nebraska and western Iowa produced mainly hail and wind damage, but heavy rainfall also occurred in parts of the area as well.
