...Central Rockies...

Day 1...
An upper trough moving into the western U.S. will encourage the
closed low over the Southwest eastward -- from the Four Corners to
eastern Colorado overnight. Models have trended a little wetter and
colder with the system -- pushing the probabilities for
accumulating snow upward over the higher terrain of the west-
central Colorado ranges. The probabilities for snow accumulations
of 4 inches or more have shown notable increases, climbing above 50
percent, across portions of the Elk and Sawatch ranges, especially
for areas above 10,000 ft.

The probability of significant ice across the CONUS is less than
10 percent.
