1902: Severe thunderstorms produced very strong straight-line winds across much of eastern South Dakota and extreme northwestern Iowa between midnight and 3 am on June 25th. Damage was widespread from Inwood down through Sioux Center and Hawarden to near Le Mars and Sioux City. An observer at Alta wrote that winds were of nearly hurricane force and moved some buildings off their foundations. Hundreds of barns were blown down and houses were unroofed around Larrabee and Sioux Center.

1877: A severe hail storm struck Muscatine County with a resident of the area observing that “the hailstones were large, from the size of black walnuts down. They fell in vast quantities and with great force. In one place, where there was a ravine with steep slopes on each side, they were washed down into the ravine, filling it to a depth of five feet, and they were so well preserved by the rubbish washed on to them, that some were seen a week from the time they fell, although some of the hottest days of summer intervened.”
