Thanks to Matthew Kulowitch for sharing this great shot of Saturday's thunderstorms that rumbled much of the day in areas from Iowa across Wisconsin into Lower Michigan, skimming along the Wisconsin- Illinois border. This shot was taken on a flight from Detroit to central Wisconsin at an altitude of about 14,000 feet.
