As moisture comes up from the southwest, western Wyoming will see snow showers today and tonight.  Meanwhile, central and eastern areas are seeing more clouds today due to an increase in atmospheric moisture.

Later today and this evening portions of south central and southeastern Wyoming will see the precipitation start out as a rain/snow mix, which will lead to icy roadways.  Tonight and overnight these mixed showers will switch all over to snow.  Moderate to some bands of heavier snow are expected, especially in the southeast, by early Saturday morning.

Blizzard Warnings and Winter Storm Warnings are in effect for Saturday for southeastern Wyoming including I-80 from west of Laramie to the Nebraska border and I-25 from the Colorado border north through Platte County.  Winter Weather Advisories have been posted for other areas in the southeast as well.  Three to six up to four to eight inches of snow are expected in portions of the southeast through Saturday night, with some locally heavier amounts.  Northeastern, north central and central Wyoming will see snow as well.

The snow will continue throughout the day on Saturday and in addition, the wind will start pick up as well.  Sustained north winds at 20-35 mph, with stronger gusts will create near white out conditions at times.  The strongest winds will be found along the state’s eastern border.  Temperatures will be colder on Saturday too.  Roads in the path of the storm will be icy and snow packed.  This will prove to be a dangerous winter storm for portions of the state.  Meanwhile, western Wyoming will see conditions improve late Saturday.

Sunday will prove to be a cold day.  There may be some additional lighter snow along the state’s eastern border on Sunday morning, but all in all the weather will slowly start to improve.  Areas of blowing and drifting snow will still be of a concern.
