The winter solstice is at 9:49 PM MST today, and it will behave like winter tonight and tomorrow along and west of the higher terrain. Generally unsettled weather is likely through Wednesday, with the bigger impacts along and west of the continental divide. A larger storm system may impact the region on Christmas weekend, but right now is looks like it will pass mainly south of Colorado.
Mountains and West:
Moist Pacific flow from the west will bring periods of snow and wind mainly along and west of the mountains this week, especially Tuesday. There may be a little lull around Christmas Eve before a storm system brings more snow on Christmas, but the main impacts this weekend may be in the mountains of southern Colorado and New Mexico.
Front Range and Plains:
Mostly dry, occasionally windy (especially Monday night near the foothills). Mild temperatures on Tuesday will be replaced with colder temperatures Tuesday evening (but not bitter cold). There aren’t any organized storms through Christmas Eve, but pieces of the western action move east and cause some brief snowy periods in some areas Tuesday evening or Wednesday. The storm system for Christmas Day through Sunday is one to watch, but it looks like the main impacts are likely to be south of Colorado Springs.
Bottom line: Be prepared for areas of wintry travel on parts of I-70 west of Denver and I-80 west of Laramie this week. By the weekend, I-25 south toward New Mexico may have wintry travel.
