A sunset shone across mammatus clouds as storm warnings were in place for parts of northwestern Texas on Tuesday, June 23.

Storm chaser Chad Casey captured this footage of what he called “the most insane display of mammatus clouds I have ever seen at sunset,” at the Hale Center.

The National Weather Service issued a severe thunderstorm warning for the Hale Center area, forecasting winds up to 60 mph and hail. Credit: Chad Casey via Storyful
