When Dennis Quaid's character is dragging Jason through the snow after Frank has died, he stops just outside of a Wendy's. Looking around, he notices that the eye of the storm is approaching, and the camera zooms in on a nearby american flag. The flag suddenly stops blowing because inside the eye of the storm there is no wind. Dennis Quaid starts to run inside, but there's another shot of everything starting to freeze up and then you see the flag again, and as it's freezing up, it's blowing in the wind again. Where did this wind come from if there's no wind inside the eye of the gigantic storm?
