July 9-10 numerous severe storms with large hail and damaging winds caused significant crop damage in an area of south central and southwest Nebraska. The National Weather Service in Hastings reported hail from 1-1.75 inches, wind gusts up to 85 mph, and crop and property damage. Hail stripped plants and high winds leveled fields just as corn was nearing pollination. (Photo by Ron Seymour)
