...Central Rockies/High Plains...
Days 1-2...

Right-entrance region upper level jet forcing, mid-level energy,
and low-level upslope flow will combine to support showers
developing over the north-central Colorado mountains Friday
afternoon before spreading east into the High Plains during the
evening and overnight hours. While snow falls across the high
terrain, rain changing over to snow is expected during the evening
and overnight hours over the High Plains. The heaviest snow
accumulations are expected to fall along the Front Range, where WPC
PWPF indicates several inches are likely for areas above 9000ft.
Lighter accumulations on the order of 2-4 inches can be expected
across far southeastern Wyoming, northeastern Colorado, and the
southern Nebraska Panhandle. PWPF shows probabilities of 50-70
percent for accumulations of 2 inches or more extending along the
eastern Wyoming-Colorado border into the southern Nebraska
Panhandle. These accumulations are most likely to occur overnight
Friday into early Saturday.

The probability of significant icing is less than 10 percent.
