Getting taller & darker. Four of them now. They will become storm clouds shortly. Whether or not the internal workings become severe is another question. Tunderstorms are forecast again. Sometime they are things of beauty as they are forming.
I saw this online earlier. Astonishing cloud formation as seen from Sheridan WY. Stunned sky-watchers in the US state of Wyoming have snapped photos of a rare cloud formation crashing across the horizon like ocean surf. The billowy phenomenon was visible on Tuesday above the crest of the Bighorn Mountains from the city of Sheridan.
