These initial supercells were the most prolific tornado producers – with the southernmost storm producing the first tornadoes west of Indianapolis and eventually prompting tornado warnings for the city itself. A second supercell quickly developed north of the city and produced a tornado in Kokomo, Indiana; this storm became a cyclic tornado producer as it crossed south of Fort Wayne and into adjacent areas of northwestern Ohio. A third supercell evolved even farther north, producing tornadoes near Fort Wayne, and tracked along the US-24 corridor into Ohio, producing tornadoes as far northeast as the southwestern suburbs of Toledo (see map above).
Additional supercells developed behind these initial tornado producers during the midafternoon hours, and continued to produce tornadoes north of Indianapolis into the evening. Another lone supercell even produced a hefty tornado near Windsor, Ontario!
