A cold upper level trof is moving through the region today and Saturday. The surface storm is likely to move from the Southwest to Nebraska as it intensifies between now and Saturday night. For eastern Colorado there will probably be snow (will lull periods) from mid afternoon through Saturday. The action on Saturday will likely shift to northeastern Colorado (mainly north of Colorado Springs).
This afternoon and early evening:
Areas of heavy snow have been impacting the mountains of southern Colorado and northern New Mexico, and there is even some lightning and thunder reported not too far from Santa Fe. An area of snow is probably going to move from south-to-north through the Front Range urban corridor from mid afternoon to mid evening. It’s not a solid area, so accumulation is likely to range from nothing to around a half-inch for Denver-Boulder-Fort Collins-Cheyenne. Out toward the Nebraska and Kansas border there may be several inches in a short time, and some freezing rain near the Kansas border.
- through 9PM
- Denver-Boulder-Fort Collins, Cheyenne: 0-0.5 inch
- Colorado Springs: 1-3 inches
- far northeastern plains 1-4 inches (some freezing rain along I-70 near the Kansas border)
Tonight and Saturday
The action will likely shift to the Front Range and high plains from Jefferson & Douglas counties northward by Saturday morning. There may be some long lull periods, but 0.5 to 4 inches seems to be the most likely snowfall for Denver-Boulder-Fort Collins late tonight and Saturday.
- after 9PM Friday through Saturday
- Castle Rock-Denver-Boulder-Longmont-Fort Collins: 0.5-4″
- Cheyenne: 3-5″
- Colorado Springs: less than 1″
- In and near the foothills won’t necessarily have the most snow
- Areas of heavy snow (more than 6″) and blowing snow are possible in far northeastern Colorado, western Nebraska, and in Wyoming east of Cheyenne.
