Storms that developed Sunday afternoon in eastern Nebraska crossed into western Iowa’s Harrison County before spreading east through Shelby and Audubon Counties late into the evening, and then into central Iowa. The storms affecting our area dropped hail ranging in size from quarters in most locations, to baseball-sized hail near Magnolia.

There were also reports of funnel clouds in and around the Harlan and Elk Horn areas late Sunday evening, and one possible touchdown of a tornado in a rural area northwest of Harlan, but there were no immediate reports of damage.
