Mammatus – the rare but stunning clouds resembling bubble-wrap – filled the skies around Denver Wednesday evening behind a towering thunderstorm. These pouch-like clouds, named after breasts, typically form in the sinking air in a storm’s wake, often signaling the worst weather has past.
The clouds were photographed mostly between 7 and 8 p.m. mountain time Wednesday evening, in some cases coinciding with the setting sun and the skies’ yellow and orange hues.
