May 30, 1998
Ten tornadoes touched down within 90 minutes of each other. A strong, 700-yard wide tornado ripped a six-mile swatch of farmhouses and electrical lines from McCook Country. The most violent tornado, an EF4 with 220 mph winds in the greater Spencer area, proved to be the most destructive in state history. It obliterated nearly all of Spencerʼs 190 buildings—including nearly every house in its northeast quadrant—and killed six people. Half of Spencerʼs residents opted never to return.
