RIVERTON, Wyo. — Western Wyoming woke up under gray skies and fresh flurries this morning as another winter storm system continues to move through the state, bringing slick roads and gusty winds to parts of the Wind River Basin, Tetons, and Bighorn Mountains.
The National Weather Service in Riverton has issued a Winter Weather Advisory in effect until 11 p.m. MST, warning that snow accumulations between 1 and 3 inches are likely in higher terrain and western valleys. Lighter totals are expected in the lower basins, but rapidly changing visibility and icy road patches will challenge drivers through tonight.
Forecasters say the heaviest snow will fall over the Tetons and Star Valley, where rates could briefly exceed one inch per hour during bursts of evening snow. Winds up to 25 mph may cause drifting snow across open stretches of Highway 26, U.S. 191, and portions of I-80.
“Travelers should plan for slick spots and reduced visibility, especially through the passes,” the Weather Service warned. “If you must drive, use caution and allow extra time.”
Conditions will gradually improve late tonight as skies clear from west to east. Still, temperatures will plunge into the teens, setting up a hard freeze for early commuters on Wednesday.
Five-Day Local Outlook:
- Today: Scattered flurries, high near 39°F.
- Tonight: Snow showers likely, low 18°F.
- Wednesday: Decreasing clouds, high 32°F.
- Thursday: Mostly sunny, high 35°F.
- Friday: Slight chance of snow, high 38°F.
