Whether they spawn a tornado or not, the clouds of a supercell thunderstorm are a thing of beauty to me. The overall structure can be extraordinary and its scale immense or, as in this picture, one part of it can show the drama on a finer level.
Here, a lowering in the storm’s structure draws your eye as it passes over a field. It is an intense scene, one which can’t help but make you wonder if a twister isn’t to follow soon (unfortunately it did not). Image taken near Lamar, Colorado on June 11, 2015.
