Thornton resident Shannon Dizmang put his camera to good use and captured a stunning time lapse video of some lenticular clouds that developed this afternoon.

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).
