Severe thunderstorms first developed across Central Nebraska during the late afternoon hours, gradually spreading southeast across portions of South Central Nebraska during the evening hours. The initial supercell development took place along and ahead of a northeast to southwest oriented surface trough, in an environment characterized by 1500 to 2500 J/kg MLCAPE and deep-layer shear of 35 to 40 knots. Some storms quickly became outflow-dominant, with wind gusts of 60 to 64 MPH reported in Sherman and Hamilton Counties, and golf ball size hail in Merrick County. While the primary cluster of severe storms focused north of Interstate 80, an isolated severe storm also developed across southwest portions of South Central Nebraska, bringing quarter to golf ball size hail to parts of Gosper, Phelps and Harlan Counties.
