CHEYENNE, Wyo. – NOAA’s Winter 2025–2026 outlook, released Thursday, Oct. 16, paints a frigid, snow-laden picture for Wyoming — with Arctic air, mountain snow, and high plains blizzards likely through February and into early March. The Climate Prediction Center’s maps show above-normal precipitation and below-normal temperatures statewide, a classic La Niña setup that favors strong storm systems and long cold spells.
According to the National Weather Service in Riverton, “Wyoming sits in the heart of the cold and snow zone this winter. Expect frequent mountain storms and bitter cold across the basins.” Western ranges — including the Tetons, Wind Rivers, and Yellowstone region — are forecast to see deep snowpack. Eastern areas like Casper, Sheridan, and Cheyenne may face strong winds, drifting snow, and subzero wind chills throughout the season.
The most active window runs from mid-January through late February, when clippers and Pacific systems collide with entrenched Arctic air. Travel on I-80, I-25, and U.S. 287 may be frequently disrupted by ground blizzards and road closures. WYDOT urges drivers to carry full winter kits, extra fuel, and emergency blankets for long hauls.
Forecasters say cold could persist into March, with lingering snow cover and delayed meltwater runoff. Ranchers and rural residents are advised to secure feed and maintain heating backups ahead of extended cold snaps.
For Wyoming, Winter 2026 looks long, snowy, and unforgiving — a true high-plains winter where preparation and resilience will matter most.
