The deadliest tornado of the April 3-4, 1974 outbreak was the F5 that hit Xenia, OH. Per the SPC, it continues to be in the top 10 of costliest tornadoes on record. Per Thomas Grazulis in Significant Tornadoes, “This was the most publicized tornado of the day and perhaps the most well-studied tornado in history, from a wind-engineering perspective.”
