Background and detail
Background. A cold front encountered a warm, moist air mass over the Mississippi River Valley, creating favorable wind shear for supercell development. This atmospheric setup led to the formation of cyclic supercells capable of producing multiple significant tornadoes, resulting in a widespread outbreak across the region.
Louisville Impact. The F4 tornado devastated Louisville, nearly destroying its downtown. Numerous unreinforced multi-story buildings collapsed, including Falls City Hall, where 44 or more fatalities occurred. This single building collapse represents one of the highest death tolls from a tornado in U.S. history.
Regional Deaths. Beyond Louisville, five other violent tornadoes occurred. A long-tracked F4 family crossed two states, killing 21 people and injuring 200. Two additional F4 tornadoes killed 14 people. In Crittenden County, six deaths occurred, five in a home at Sheridan.
