The CSU-CHILL radar observed several severe thunderstorms during the afternoon hours of 21 June 2010. At ~2330 UTC Morgan County Colorado was being affected by this activity. The severe weather reports compiled by the Storm Prediction Center include 1.5 inch diameter hail 1 mile south of Brush at 2316 UTC and 1.0 inch diameter hail and 60 mph wind gusts 5 miles northeast of Brush at 2333 UTC.
