...Central Rockies/High Plains...
Day 1...

Ongoing precipitation over the central Rockies is expected to
increase through the evening as a mid-level shortwave moves across
the region. Meanwhile, right-entrance region upper jet forcing will
increase the potential for banded precipitation extending from the
Rockies into the High Plains. With mostly snow expected over the
mountains, mixed precipitation changing over to snow during the
evening and overnight hours is forecast over the High Plains. WPC
PWPF shows 50 percent or greater probabilities for additional
accumulations of 6in or more in the Front Range, mostly for areas
above 9000ft. PWPF continues to show that at least light
accumulations of 2-4in are likely to extend east along the eastern
Colorado-Wyoming border into the far southwestern corner of the
Nebraska Panhandle.

The probability of significant icing is less than 10 percent.
