Cold start to 2018 ahead of warming trend
DENVER -- There was patchy fog and temperatures in the single digits on the first morning of 2018. There will be sunshine on New Year's Day, but highs will only reach the mid-20s in Denver, Boulder, and Fort Collins. The mountains will stay mostly dry on Monday with partly sunny skies, and highs in the 20s and 30s. It's going to be a dry stretch until Sunday.
