Overview

A strong winter storm will result in another prolonged period of unsettled weather to end 2022 and begin 2023. Moderate to heavy snow is expected for the mountains of eastern Utah and western Colorado as well as some adjacent valleys through Monday. Be prepared for rapidly changing winter driving conditions and snow-packed, icy roads when traveling this holiday weekend. Mild temperatures in the lower valleys will lead to rain or a rain/snow mix initially before cooler air arrives later in the weekend.
