An intense upper level system surged northeast across Kansas that brought an equally intense surface cyclone across the state in the afternoon. There was a moisture-rich environment entrenched across Kansas. This combined with the powerful cyclone crossing the state, numerous thunderstorms, several of which were severe, produced torrential rains that caused major flooding and flash flooding from the evening hours the 20th until late in the afternoon on the 22nd.
