This time-lapse, taken over several hours, shows an amazing stationary supercell being produced over the Black Hills of South Dakota on 1 June.
“I was fortunate enough to have the entire event unfold right in front of me over,” writes the video’s creator, Nicolaus Wegner. “Truly one of the most beautiful natural weather phenomenon I have ever witnessed.”
The time-lapse was taken at one second intervals.
