2003 South Dakota tornado outbreak
The 2003 South Dakota tornado outbreak, known locally as "Tornado Tuesday", was a tornado outbreak that occurred in the southeastern and east central part of South Dakota in the United States on June 24, 2003. At the time, this outbreak tied a United States record for the most tornado touchdowns in a single day for one state, with 67. The event was part of a larger outbreak that produced 125 tornadoes. However this record was surpassed by a tornado outbreak in Kansas on May 23, 2008 when 73 tornadoes hit the state, including two that started in Oklahoma. It was also the largest tornado outbreak ever recorded in the astronomical summer period that was not related to a tropical cyclone.
