Laramie, Wy – A major winter storm is expected to drop
heavy snow across central and southern Wyoming late Monday through early Wednesday morning.
The National Weather Service says an arctic cold front will push south across the state late Monday afternoon and combine with a potent surge of Pacific moisture streaming north into Wyoming ahead of a strong low-pressure center.
East-northeasterly winds are likely to create upslope conditions across southern and central Wyoming, resulting in heavy snowfall, especially on eastern slopes.
The weather service has issued a winter storm watch for Kemmerer, Green River, Rock Springs, Wamsutter, Jeffrey City, Casper, Lander, Riverton and Thermopolis.
Also included in the watch are the Green, Rattlesnake, Owl Creek, Bridger and Wind River Mountains.
Six to 12 inches of snow is possible by early Wednesday morning in lower elevations, with 12 to 18 inches in the mountains in the watch area.
East-northeast winds of 15 to 25 miles an hour will cause blowing and drifting.
A winter storm watch means severe winter weather is possible but not imminent.
Potential exists for significant snow and ice accumulations.
Driving conditions may become hazardous and residents are encouraged to monitor the latest forecasts.
