Overview

During the afternoon of June 12th, 2001 a series of supercell thunderstorms produced eight reported tornadoes across northeastern Wyoming and southwestern South Dakota. Fortunately, only isolated areas of damage were reported from these storms.

The map at right shows the preliminary tornado reports (red "Ts"), which eventually were reduced to eight confirmed tornadoes because the same tornado was reported multiple times on several occasions. The green swaths represent the supercell thunderstorm tracks.
