For the last decade, Kansas-based photographer Chad Cowan has driven almost 100,000 miles across the United States chasing powerful supercell thunderstorms and recording them in high definition. The endeavor began as a personal project to capture a few storms as they developed but quickly grew into
"Wave In The Sky". The severe thunderstorm near Graham, Texas yesterday (4-18-15) created a "Breaking Wave" shape as it started to intensify. I still can't get over the magnificent variation of blues it was displaying.
