Cheyenne, Wyoming – A warmer-than-normal and wetter weather pattern is expected to develop across Wyoming heading into Valentine’s Day weekend, increasing the likelihood of snow in the mountains, rain or mixed precipitation at lower elevations, and intermittent travel disruptions from Saturday through midweek. While no single major winter storm is locked in, multiple systems could create cumulative impacts across the state’s highways and mountain corridors.
According to the National Weather Service Climate Prediction Center, Wyoming is favored for above-normal precipitation and above-normal temperatures during the February 14–18 period. This setup weakens prolonged Arctic cold while allowing moisture-rich systems to move across the Rockies and High Plains.
In southeastern Wyoming, including Cheyenne, Laramie, and along I-25, milder daytime temperatures may allow precipitation to fall as rain at times. Overnight cooling could still bring periods of wet snow or slush, increasing the risk for slick travel during early morning hours, especially on bridges and elevated roadways.
Central Wyoming, including Casper and Riverton, may see fluctuating precipitation types as temperatures hover near freezing. Slushy road conditions are possible at times on I-25 and Highway 20/26, particularly during nighttime and early morning travel windows.
Across western Wyoming, including Jackson, Pinedale, and the Tetons, snow is expected to be the dominant precipitation type. Warmer air aloft may lead to heavier, moisture-laden snowfall, increasing impacts over Teton Pass, Togwotee Pass, and South Pass. Winds combined with fresh snow could reduce visibility at times.
Along I-80 in southern Wyoming, periods of precipitation combined with gusty winds may create variable driving conditions, especially between Rawlins and Laramie. The Wyoming Department of Transportation advises travelers to monitor conditions closely during changing weather.
Air travel through Cheyenne Regional Airport and Casper–Natrona County International Airport may see occasional delays during periods of low ceilings or steadier precipitation. WYDOT crews are expected to remain in active winter operations throughout the period.
This warmer, wetter pattern is expected to persist into midweek. Additional advisories may be issued as individual systems become clearer, and residents are urged to stay alert for updated alerts, particularly for mountain travel and overnight driving conditions.
