9–13 inches of wet snow
Cheyenne gets significant snowfall but also gets rapid clearing from dry air and Chinook winds. A foot of snow can fall and melt in 24–48 hours — which means districts here focus on the melt-freeze cycle (overnight ice on roads cleared yesterday) as much as on fresh accumulation. Temperature swings of 40–60°F in a single day are normal, and that's what actually determines road conditions in the morning.
Cheyenne sits at elevation, which means the air is drier and the snow is lighter and more easily plowed than eastern snow of equal depth. A six-inch powder event in Cheyenne is equivalent to maybe two inches of wet snow in the northeast — easier for plows, easier for drivers, less likely to close schools. What does close schools here is the subsequent melt/freeze: daytime sun melts cleared pavement, overnight cold refreezes it to black ice, and the morning drive is dangerous even though no new snow has fallen.
Nearby mountain districts see dramatically more snow than Cheyenne proper. Teachers who commute from the foothills or mountain towns may face impassable roads even when Cheyenne's roads are clear. That cross-district staffing problem sometimes drives closures that surprise parents in the city itself.
Cheyenne averages 51 inches of snow per year but benefits from frequent Chinook wind events that can melt several inches in hours. Schools typically close 3–5 times per winter, primarily for storms that exceed plow capacity or generate ice conditions.
