Clouds will be on the increase this afternoon and rain showers are likely to develop by evening. There may even be a few places that hear thunder, an atypical occurrence for November. The snow level may initially be near or above Nederland’s elevation, then lower during the night.

The best chance for precipitation is from about sunset to about the midnight hour.  The best chance for snow in the lower elevations is in the late night or early morning when the coverage of precipitation is likely to be more spotty.  So there isn’t a high probability for measurable snow in the urban corridor, but there is a chance.

Most likely snow amounts:

Nederland, Estes Park, Cheyenne: 2-6 inches

Fort Collins, Boulder, Denver: 0-1 inch

Colorado Springs, Pueblo: most likely no measurable

Western mountains: 6-12 at some of the high passes.

The coldest part of the upper storm system is likely to pass overhead on Friday. So a few snow showers may develop in the mountains, and possibly a sprinkle or flurry in the lower elevations, but nothing of significance.

If the Front Range cities get through this week without the first snow, the next chance appears to be next Tue-Wed.
