Moisture returning to eastern Nebraska and western Iowa during the afternoon on June 20th allowed for the development of scattered thunderstorms. The thunderstorms were responsible for mainly large hail across the area, but some strong winds were reported as well. The thunderstorms also dropped very heavy rainfall, especially over the Omaha Metro area, which led to significant flash flooding in parts of the metro.
