Overview

During the late afternoon of August 19th, a supercell developed across northeast Wyoming and tracked directly over Devils Tower, where it caused extensive damage to trees, buildings, campers, and vehicles. The National Park Service closed Devils Tower due to the severe storm damage.  The supercell then tracked eastward through the Northern Black Hills and onto the plains of western South Dakota, and continued to produce large hail, strong winds, and heavy rain, before dissipating later in the evening.
