ORIGINAL CAPTION: Hail pelted South Dakota communities in a weekend storm that also brought a tornado to southwest Minnesota and 100 mph winds to the Iowa Great Lakes. "I was sitting at my computer and suddenly heard a bang. I looked into the yard and could see these big stones bouncing," said Charles Mack, 64, a retired implement dealer in Clark. Hailstones smashed windows and damaged roofs, crops and vehicles. (images from NOAA, submitted by Kimberly Dawley)
