Unseasonably cold, arctic air remained in place across western and central Wyoming overnight under a clearing sky. Fresh snow cover earlier in the week only helped to push temperatures to well below zero for the second night in a row. Many areas recorded low temperatures between -25F and -15F. The coldest temperatures were recoreded in the lower valleys of the Big Horn Basin and Yellowstone National Park where overnight temperatures bottom out between -30F and -46F.
