Episode description: During one of the worst tornado seasons on record, a camera team chases across the Midwest, capturing hair-raising footage of highly destructive twisters in action. Meanwhile, two scientists at the University of Oklahoma pursue radically different approaches to forecasting twisters: One relies on "virtual tornadoes" created inside supercomputers, while the other involves hunting down real-life storms to collect data firsthand.
