About the Author: Eugene Thieszen
Gene has been fascinated by severe storms and tornadoes since the May 1964 Nebraska F-5 which passed near his family’s farmstead. Although he chased sporadically for quite a while, Gene began to avidly pursue chasing in 1999 and has a definite preference for dry line supercells. His skills as a photographer and videographer have enabled him to capture some dramatic shots that embody both the beauty and destructive power of weather.
