Wyoming – A hard, wintry wind sweeps across Riverton this morning, carrying bursts of snow dust that glint under weak daylight. Across the Wind River Basin and nearby passes, travelers can expect slick conditions and near-whiteouts where stronger gusts meet drifting flakes. It’s the kind of morning that feels like winter has officially taken hold of central Wyoming.
According to the National Weather Service in Riverton, a Winter Weather Advisory remains in effect for several western ranges and valleys, while a Winter Storm Warning continues for the Teton and Gros Ventre Mountains until 2 p.m. Saturday. Heavy snow is expected across higher elevations with strong crosswinds through the Wind Corridor, the Absarokas, and the upper Green River Basin. Gusts could reach 50 mph, sharply reducing visibility and causing treacherous travel—particularly along Highway 26 and U.S. 287.
Today stays mostly cloudy, reaching near 39°F before a gradual clearing. Winds ease slightly late in the day, but any moisture on pavement may flash-freeze by dusk as temperatures drop into the 20s.
Saturday brings bright sun over Riverton with highs near 45°F, yet surrounding peaks will still see lingering snow and gusts up to 40 mph. Those driving west toward Dubois or Jackson should expect rapidly changing conditions through midday.
Sunday looks calmer, turning sunny with highs in the low 40s, though another chance for snow showers returns early next week as December’s storm track remains active across the central Rockies.
Long-range models suggest additional snow chances Dec. 11–17, keeping Wyoming’s holiday travelers on alert for more winter waves.
