May 23, 1989:

A complex of thunderstorms moved from southwest Minnesota through Iowa. One small tornado touched down briefly in Lyon County. But the main story with this complex was high winds and hail. Baseball size hail fell just north of George in Lyon County. In addition, two inch hail occurred in Sac County in Schaller and Odebolt and golf ball size hail fell in Caroll, Iowa. Needless to say, the hail caused a lot of damage to vehicles, trees and roofs. Thunderstorm winds of 60 miles an hour were also common across all of northwest Iowa with these storms.
