A line of severe thunderstorms marched out of Wyoming and across the Northeast Plains of Colorado.  One tree was reportedly downed in Fort Collins.  A tornado reportedly touched down briefly near Ault.
Morgan County suffered the most damage as large hail, strong winds and very heavy rain moved through the area.  Utility pole were downed north of Brush causing scattered outages.  Two trees; 3 to 4 ft in diameter, were blown down near Wiggins and Brush.  Some memorial stones at the Cemetary in Brush were damaged.  Large hail the size of baseballs knocked the windows out of a home south of Brush.  Extensive crop damage was also reported in the same area.  Near State Highway 6 and Interstate 76; between Brush and Hillrose, hail piled up along the road with drifts up to a foot deep.  Plows from the Colorado Department of Transportation were sent out to clear the roads.  In addition, golfball hail caused extensive crop damage in western Logan County.
Heavy rain caused flash flooding in northeast Morgan County.  A bridge approach was washed out on County Road 31.  The wash was about 4 feet wide and 12 feet deep.  The highwater forced the closure of the roads to traffic.  There were other washouts along County Roads 26, 32, AA and JJ.
