Riverton, WY – Brisk winds are back across the Wind River Basin as Wyoming braces for a sharp weather change heading into the weekend. Clouds will thicken Friday as a cold front sweeps across the state, bringing blustery gusts and a chance of snow by late day—just as post-Thanksgiving travel picks up across the mountain passes.
According to the National Weather Service in Riverton, light rain and snow showers are likely Friday afternoon and evening, with winds up to 25 mph and highs near 47°F before temperatures plunge into the teens. The mix may briefly create slick spots across Teton and Togwotee Passes, where winter travel conditions are possible.
Saturday will turn calmer and mostly sunny but much colder, with highs struggling to reach the mid-20s. By Sunday, the region settles under a drier pattern, though the chill will linger—morning lows could dip near 5°F in valley areas. The coming week trends colder statewide as early December begins, part of a larger shift bringing below-normal temperatures across much of the central U.S.
Meteorologists advise travelers to plan ahead and keep winter gear ready. “Even a light snow can create sudden slick stretches,” forecasters warned. Residents are also encouraged to prepare for the next cold surge expected around December 2–6.
