Lots of Pacific moisture over the last few days have produced high clouds, but little or no precipitation in the central Rockies. A more impressive area of Pacific moisture late Christmas Day and overnight will increase the likelihood of snow in the mountains and west, but the chances are still small for the eastern foothills and plains. A colder air mass late Friday and Saturday will bring the next chance for snow.
Mountains and West Slope
Expect 4-10″ at the high mountain passes and west-facing slopes, mainly Christmas afternoon and night. Another round of snow might arrive Friday afternoon, mainly for the southern Colorado mountains.
Front Range foothills and plains
There is a small chance for showery precipitation (snow or rain & snow) late Christmas Day or night, but the chance for accumulation is only about 10% in any one location. Temperatures should be cooler, but still average to above-average through Thursday.
On Friday there is a good chance for some snow in southeastern Colorado, mainly south of Colorado Springs. A cold front on Friday evening or Saturday morning will bring a chance for more widespread light snow. It is looking like the temperatures by Saturday and Sunday are likely to be a little below average for the first time in a while.
