Overview

Severe storms with heavy rain, flash flooding, large hail, tornadoes, and damaging straight-line winds moved across northeastern Wyoming and western South Dakota during the afternoon and evening of July 4, 2019. Three short-lived tornadoes occurred in the higher Black Hills (one south of Black Fox Campground, one east of Deerfield Lake, and another northwest of Jewel Cave; damage surveys were done on July 26th and August 2nd to confirm). Otherwise, considerable damage was reported because of flooding and the straight-line winds. Fireworks shows also were cancelled or postponed because of Mother Nature's natural fireworks display. The lightning map to the right shows that there were a lot of cloud-to-ground lightning flashes across the Black Hills area.
