An upper level storm system moved into Nebraska and Iowa on the afternoon of April 15th. This allowed for a dry line to move through southeast Nebraska with a trailing cold front moving into northeast Nebraska. Both of these boundaries served as a focus for severe weather activity. Supercells initially developed along the dry line in southeast Nebraska and moved into southwest Iowa. These thunderstorms generally produced large hail, though one tornado did occur with the initial development. Supercells then developed along the cold front in northeast Nebraska and tracked southeast, and eventually into western Iowa by late evening. These produced significant hail and wind as they tracked across the area. The severe weather threat ended by late evening as storms moved out of the area.
