A fast moving winter storm moved into the Great Basin early Thursday morning, December 22 and brought snow to much of eastern Utah and western Colorado through midday Friday, December 23. The southern and central Colorado mountains were favored. Many locations saw a mixed bag of precipitation on Thursday, especially after warm air aloft worked its way into the Four Corners Thursday afternoon, causing snow levels to rise and allowing for some rain to briefly mix in with the snow before transitioning back to all snow Thursday night. Snow even accumulated in the valleys, where 1 to 3 inches was reported. The abundance of low level moisture in wake of snowfall resulted in areas of localized dense fog which created some slick roads and hazardous driving conditions.
