It is January in Denver and the National Western Stock Show is in town, which can only mean one thing ... cold and snowy Colorado weather is around the corner. It is a tradition at this point, and this year will be no different. An arctic blast will bring temperatures 20 to 40 degrees below average and a chance for snow.

We'll see one more mild day across Colorado before a strong cold front races through Friday night. Temperatures will climb into upper 40s by the afternoon, with light snow developing by evening commute.
