Areas around and north of Cheyenne should be ready for significant snow and wind late tonight and Wednesday. Meanwhile, the Colorado Front Range urban corridor (and adjacent foothills) should get the wind but probably not the snow. The storm is likely to track across the Front Range near the CO/WY border late tonight bringing snow to the north and some showery precipitation and a blustery wind to the south.
The sequence for the Front Range urban corridor: 1) showers and maybe a thunderstorm this afternoon or evening (changing to snow in mountains). 2) Becoming cold enough for snow in the predawn hours of Wednesday, but probably very few showers and only spotty accumulation. 3) Possibly a period of more numerous snowshowers Wednesday afternoon or evening, but still only spotty minor accumulation.
Most likely accumulation through Wed evening:
Cheyenne area: 5-10 inches, more immediately to the north.
Fort Collins: probably 0-2″, but close enough to the storm that there is a small chance of 2-4″.
Longmont, Boulder, metro Denver, Colorado Springs: mainly 0-1″, a few localized heavier showers may produce 1-2″
Nederland, Estes: 3-6, a bit more in the higher mountains.
Thursday: a weak disturbance following the storm looks likely to bring some areas of light snow Thursday afternoon or evening.
