Outflow from thunderstorms earlier in the day over Nebraska helped trigger new storms during the afternoon over Rawlins county. As the afternoon progressed, storms increased in coverage, and more storms moved into the region from eastern Colorado. Most reports from the public and spotters were for heavy rainfall and isolated hail, but one heavy rain event led to damage as a police car had to be abandoned due to high water in Colby.
