Wyoming Snow Day Forecast & School Closings
Wyoming is one of the windiest and most sparsely populated states in the nation, and both characteristics shape its snow day culture. The Teton Range can exceed 200 inches of snow per year, while Cheyenne on the high plains averages roughly 60 inches at 6,000 feet. With some of the longest school bus routes in the country crossing open rangeland where ground blizzards can strike with little warning, closure decisions often hinge on wind and road visibility rather than snowfall totals.

Snow Zones in Wyoming
Jackson, the Tetons, and the mountain valleys of western Wyoming. Ski-area elevations routinely exceed 300 inches. Valley floors like Jackson average roughly 87 inches. Schools close roughly 5–12 times per season, with avalanche-related road closures on Teton Pass a major factor.
Lander, Casper, and the central corridor. Elevation and proximity to the Wind River Range keep totals high. Casper's exposed position makes it vulnerable to both heavy snow and extreme wind. Schools close roughly 4–8 times per year.
Sheridan, Cody, and Gillette. Somewhat sheltered by the Bighorn Mountains, but Arctic outbreaks bring extreme cold and blowing snow. Schools close roughly 3–6 times per year, with wind chill an independent trigger.
Cheyenne, Laramie, and the I-80 corridor. High elevation keeps totals substantial, and the Laramie Valley is one of the windiest inhabited places in the U.S. Ground blizzards can create zero-visibility conditions even without new snowfall. Schools close roughly 3–7 times per year, with wind a major factor.
Rock Springs, Green River, and the Red Desert region. Cold and windy with moderate snow. Highway closures on I-80 are frequent in winter and affect both travel and school operations. Schools close roughly 2–5 times per year.

Notable Winter Storms
One of the worst blizzards in Wyoming history. Sustained winds over 70 mph combined with heavy snow isolated entire communities for weeks. Livestock losses were catastrophic and the military conducted airlifts to deliver supplies. Schools closed for extended periods across the state.
An extremely early blizzard struck western South Dakota and eastern Wyoming. The Black Hills received 4 feet and some Wyoming communities saw 2+ feet with trees still in leaf. Schools closed for multiple days and the storm caused catastrophic livestock losses.
A powerful bomb cyclone brought blizzard conditions to southern Wyoming with wind gusts exceeding 100 mph near Cheyenne. I-80 was closed for over 24 hours. Schools closed across the southern tier and the storm caused widespread damage.
Extreme winds of 80–100+ mph combined with snow created ground blizzard conditions across southeastern Wyoming. I-25 and I-80 were closed. Schools closed early for holiday break and some communities lost power for days.
Snow Day FAQ
How many snow days does Wyoming get per year?
Mountain communities near Jackson close roughly 5–12 times per season. Central Wyoming including Casper averages 4–8. The high plains around Cheyenne see 3–7. Wind-driven closures significantly add to the count across all regions.

What triggers a snow day in Wyoming?
Wind and road visibility are often bigger factors than snowfall. Many Wyoming districts close based on highway closure reports and wind speeds rather than snow forecasts alone. Mountain districts close for avalanche danger and pass closures. Extreme wind chills below -30°F trigger closures statewide.
Does Wyoming use virtual snow days?
Wyoming allows remote learning at district discretion. Some larger districts have adopted virtual options, but broadband limitations in rural areas remain a significant barrier. Many districts still rely on calendar buffers and traditional makeup days.
Why does Wyoming close schools for wind even without much snow?
Wyoming is one of the windiest states in the nation, and its open terrain creates extreme ground blizzard conditions. Wind can blow existing snow into impenetrable drifts and reduce visibility to zero. School buses traveling long rural routes across open rangeland face particularly dangerous conditions, making wind speed and road visibility the primary closure factors.
