Filming was to originally take place in California, but De Bont insisted the film be shot on location in Oklahoma. Shooting commenced all over the state; several scenes, including the opening scene where the characters meet each other, as well as the first tornado chase in the Jeep pickup, were filmed in Fairfax and Ralston, Oklahoma. The scene at the automotive repair shop was filmed in Maysville and Norman. The waterspout scenes were filmed on Kaw Lake near Kaw City. The drive-in scene was filmed at a real drive-in theater in Guthrie, though some of the scene, such as Melissa's hotel room, was filmed in Stillwater near the Oklahoma State University campus.
