Cirrus Spissatus

Cirrus Spissatus

Thick plumes of cirrus -- spissatus to denote sufficient density to blur or hide the sun -- stream high above cliff-forming Ordovician Bighorn dolomite in Tensleep Canyon, Wyoming. These high clouds formed in an area of strengthening upper level lift, ahead of a trough that would support intercept-worthy severe storms in northeastern Wyoming later that day.
