Cheyenne, WY – Heavy mountain snow returns to southern Wyoming tonight as a fresh round of winter weather moves into the region, bringing hazardous conditions through Monday evening. The National Weather Service warns that outdoor recreation and high-elevation travel could become dangerous as snow intensity builds overnight.
According to the National Weather Service in Cheyenne, a Winter Weather Advisory is in effect from 8 p.m. Sunday to 8 p.m. Monday for the Sierra Madre and Snowy Ranges, including the communities of Albany and Centennial. Forecasters expect 6 to 12 inches of snow, with locally higher totals possible above 10,000 feet. Wind gusts could reach 45 mph, creating pockets of blowing and drifting snow.
The advisory spans a critical 24-hour window when visibility may drop sharply, especially in exposed terrain. According to the NWS, hunters, hikers, and anyone recreating in the backcountry may become disoriented due to falling and blowing snow. Those traveling on mountain roads should be ready for slick surfaces and rapidly changing conditions.
Forecasters say the snow will intensify late Sunday night, with moderate to heavy bursts possible through early Monday. Temperatures are expected to remain below freezing across high elevations, allowing snow to accumulate quickly on roads, trails, and passes.
Drivers are urged to slow down, increase following distance, and use extreme caution, especially during early Monday travel hours. The NWS reminds residents to watch for icy steps, sidewalks, and driveways as freezing conditions persist.
