To say the show in the sky yesterday evening was amazing doesn’t do it justice. While a beautiful sunset unfolded to the west, my eye was drawn to the north where these fantastic lenticular clouds had formed. The glow from the sunset bathed them in orange and when set against the brilliant, blue Colorado sky… Well, it was magical!
Also known by their scientific name of altocumulus standing lenticularis, these clouds are not entirely unusual in Colorado on the Front Range during the winter. Strong jet winds force moist air to be pushed up by the rugged terrain of the adjacent Rocky Mountains. This creates a wave-like pattern of air flow that condenses at high altitudes (usually around 20,000 feet).
