Snow Moves Into the West and Spreads East This Weekend
Pacific moisture is moving into the state, with snowfall already falling in portions of western and south central Wyoming this morning. Snow will continue to fill into all of western Wyoming as the day wears on and will also move across portions of southern Wyoming. Stretches of I-80, especially from Evanston east to Laramie will see snowfall, and roads in the area will become slick this evening and tonight. Winter Storm Warnings and Winter Weather Advisories are posted for the west now through the weekend. The Sierra Madre and Snowy ranges in South Central Wyoming are also under a Winter Storm Warning through late Sunday.
The snow will spread east on Saturday and Sunday. It will snow off and on throughout much of the state this weekend. Travelers please be advised of slick and snow packed roads.
Besides the snow, another concern will be the wind. Very strong, gusty winds are expected to develop in portions of the southeast later today and then continue through the weekend. High Wind Warnings are posted for portions of the southeast through Sunday morning. West to southwest winds, sustained at 30-45 mph will gust to 60 mph at times. The wind combined with the snow will lead to poor traveling conditions especially around Elk Mountain, Arlington and between Laramie and Cheyenne along I-80 and along I-25 from the Colorado border north to Casper.
As far as temperatures go, they will continue to climb out of the deep freeze. Most areas will make it into the 20s and 30s over the next three days with teens and lower 20s for the mountains and valley areas.
