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.
Continuity mistake: In the scene where the large hail falls and the car is trying to dodge around it, when they show scenes from inside the car, if you look behind them you can see no hail falling, nor any hail on the ground.
