On June 8, 1984, the city was hit by a deadly F5 tornado. After tornadoes broke out across the Midwest, including tornadoes that killed four people in Missouri and Iowa, a tornado watch was issued at 11:00 p.m. CT, but most residents had went to sleep. A line of thunderstorms entered Wisconsin from Iowa/Illinois border shortly after midnight. A sharp bolt of lightning followed by a loud clap of thunder cut power to the city, awakening residents. Nine people died, and two hundred were injured.
