May 24.  The largest known tornado outbreak in Wyoming occurred over northern and

                Nebraska panhandle late on this day in 1997.  Over 7 ½ inches of rain was
                reported over western Kimball county from thunderstorms which caused major
                flooding along Lodgepole Creek from Bushnell east to the Cheyenne county line.

May 25:  The Lodgepole Creek floodwaters from Kimball county spread east across Cheyenne
                county, inundating homes and businesses in Potter, Nebraska with water up to 4 feet
                deep.  Two bridges across Lodgepole Creek were washed out, as well as 30 feet
                of railroad track.  Over 80 miles of farmland along Lodgepole Creek were covered
                with several feet of flood water. Total damage estimates were around 2.5 million.
