July 20, 2002:

An extremely strong severe thunderstorm moved over Rapid City and across the adjacent plains east of town. Downburst winds and the associated gust front caused damage along a nearly 30 mile long path. Extensive tree damage occurred throughout the eastern half of the city with countless trees and branches in excess of 24 inch diameter felled. Two roofs were torn off by the winds. Flying debris damaged numerous cars and buildings. The NWS office in downtown Rapid City measured an 80 mph wind gust, with meteorologists noting winds were sustained at 60 to 70 mph for 5 minutes. Ellsworth AFB wind equipment measured a 106 mph wind gust from the thunderstorm as it passed. Costs associated only with tree damage and cleaning up debris were conservatively estimated at $500,000.
