May 25, 1985:
During the afternoon hours, thunderstorms developed along the east side of the Black Hills. The storms produced quite a bit of lightning and over the course of 2 hours started 18 small fires in the Black Hills. Fortunately, most of the fires were small and easily contained. One unfortunate fire fighter was struck by lightning as he was helping to extinguish a blaze that burned some 50 acres of grassland and forest. Thankfully, the man lived, but he did suffer several broken bones, burns, and major damage to his ears. The strike was so powerful that a man standing over 150 feet away was dropped to his knees.
May 25, 2008:
A rare, large and destructive EF5 tornado created a 43 mile long path across Butler and Black Hawk counties in Iowa. This tornado killed eight people, injuring dozens and causing several millions of dollars worth of destruction. After the initial touchdown, the tornado quickly grew in size and intensity as it approached the town of Parkersburg. The tornado was nearly three quarters of a mile wide as it moved through the southern end of Parkersburg. A third of the town was affected by devastating damage with nearly 200 homes destroyed. This was the first EF5 tornado to strike Iowa since June 13, 1976 and only the third EF5 tornado to occur in the United States in the past 10 years.
