As Missouri enters tornado season, a look at past US twisters [INFOGRAPHIC]
Mid-Missouri got a taste of tornado season Thursday as the National Weather Service issued a tornado warning for southern Boone County. To get some historical perspective on how twisters have ravaged the U.S., we've built a map showing all of the nation's tornadoes from 1950-2012. It uses data from TornadoHistoryProject.com, which in turn pulls its numbers from the weather service's Storm Prediction Center.
