A complex of thunderstorms developed early this morning across Central Iowa with the passage of a warm front. This led to what is called backbuilding of storms for a period of time especially between 8:30 and 10 AM for a few counties. Backbuilding leads to continued heavy rain over the same locations for a period of time. The primary counties impacted included Guthrie, Greene, Carroll, Boone, Dallas, Polk, Story and Jasper.
