Cheyenne, Wyoming – Snow chances are increasing across Wyoming’s mountain regions as an active weather pattern refocuses on the northern Rockies during the February 7–20 period, bringing a higher likelihood of accumulating snowfall at elevation while lower basins see more variable conditions.
According to long-range outlooks, temperatures across Wyoming are expected to fluctuate near seasonal levels, but colder air aloft combined with periodic Pacific disturbances favors snow development in the high terrain. This setup is especially supportive of snowfall across the Tetons, Absarokas, Wind River Range, and Yellowstone region.
The shift follows a broader winter pattern reinforced earlier this month by Winter Storm Fern, which helped lock in colder air across much of the central and western United States. As storm tracks align more consistently with the northern Rockies, moisture interacting with Wyoming’s terrain increases the potential for repeated mountain snow events.
Mountain communities and recreation areas near Jackson, Teton Village, Dubois, Pinedale, and Yellowstone National Park could see periodic snowfall, with stronger systems capable of producing meaningful accumulations. Travel impacts are most likely along Teton Pass, Togwotee Pass, and stretches of U.S. 26, U.S. 287, and U.S. 191, where snow-covered roads and reduced visibility can develop quickly.
Lower elevations, including Cheyenne, Casper, and Rock Springs, may see occasional precipitation, but snow chances there remain more dependent on storm strength and track.
Wyoming Department of Transportation officials urge travelers to monitor road conditions closely, especially during peak winter recreation travel. While exact timing remains uncertain, forecasters say the broader pattern supports rising mountain snow chances through mid-February, with additional advisories possible as individual systems come into focus.
