Help on looking for a Story

I thought it was a Bob Arnold story from Zapped, but apparently not. MC is a Ham Radio operator, who is involved with a group that tracks weather phenomenon. S/He goes to an older drive-in theater just prior to a major storm where the storm wreaks havoc on the theater with several pieces of the large screen are torn loose.
That's about all I can remember of the story. Any help is greatly appreciated.

Thanks
