Continuity mistake: In the scene where Lloyd is briefing his team about the events of the next few hours, there is a shot in which he says the words 'weather systems' as someone walks across the screen from the right. Immediately the camera cuts to a close-in shot of Lloyd. But right at the end of the scene, the exact same shot is shown again, minus the sound of Lloyd saying 'weather systems'.
Continuity mistake: The hail comes through the window and kills the driver. After the girl moves him to the other side of the car, the windshield is whole again.
