Winter Storm Warnings in Cheyenne, Wyoming
Cheyenne sits at nearly 6,000 feet on the high plains of southeastern Wyoming, where cold Arctic air and moisture-laden systems collide with enough regularity to make winter a serious season. Across the 13 years analyzed from 2012 through 2024, the city averaged 47.4 inches (120.3 cm) of snowfall per year — a substantial total that reflects both the elevation and Cheyenne's exposure to powerful upslope storm tracks.
The snowiest months are March, April, and February, in that order, meaning late-season storms are often the most impactful. Average winter overnight lows hover around 19.6 °F (−6.9 °C), cold enough that snow accumulates quickly and roads can ice over with little warning.
Truly heavy snow events remain relatively uncommon — Cheyenne experiences roughly 0.7 heavy-snow days per year on average, with significant major-snow events occurring closer to once every ten years. When those storms do arrive, though, they can be severe.
A winter storm warning signals that dangerous conditions are either imminent or already occurring. Exactly what triggers that threshold varies by region; the criteria applied to Cheyenne differ from those used along the coasts or in lower-elevation areas. In practical terms here, a warning means travel may become extremely difficult or impossible, and residents should take immediate precautions.
