Montana Snow Day Forecast & School Closings

Snow Days per Year3–18+ (varies by region)
Snow SeasonOctober through May

Montana's vast size and dramatic terrain create extreme winter variation — from western mountain valleys that routinely exceed 100 inches of snow per year to eastern prairies where bitter cold and wind are often more disruptive than accumulation. With school districts spanning thousands of square miles and bus routes winding through mountain passes, Montana's snow day decisions are shaped by remote geography and some of the most intense winter weather in the lower 48.

Snow Zones in Montana

Western Mountains & Glacier Country 60–150+"/yr

Whitefish, Kalispell, and the Flathead Valley receive heavy Pacific moisture, while higher elevations near Glacier National Park can exceed 200 inches. West Yellowstone averages roughly 144 inches. Schools close roughly 6–15 times per season, with mountain pass closures and avalanche danger extending closure durations.

Southwest Montana & Mining Country 45–75"/yr

Butte, Bozeman, and Helena. Higher elevation keeps totals above statewide averages, and Chinook winds can cause dramatic temperature swings. Schools close roughly 4–8 times per year. Bozeman's Gallatin Valley can see rapid-onset storms that catch forecasters off guard.

Hi-Line & Northern Plains 35–55"/yr

Great Falls, Havre, and the Hi-Line along the Canadian border. Arctic air masses produce extreme cold and blowing snow across the open plains. Wind chill is often the primary closure trigger. Schools close roughly 4–8 times per year, with cold-only closures common when temperatures drop below -20°F.

Central Montana & Yellowstone Valley 35–60"/yr

Billings, Lewistown, and the central tier. Billings sits relatively sheltered at lower elevation but still averages roughly 57 inches. Chinook events can melt heavy snow rapidly. Schools close roughly 3–6 times per year.

Eastern Montana 25–40"/yr

Miles City, Glasgow, and the eastern prairies. The least snow in the state, but extreme cold and wind create dangerous conditions. Temperatures can remain below -20°F for extended periods. Rural bus routes across vast distances are the primary closure concern. Schools close roughly 3–7 times per year, often for cold.

Notable Winter Storms

January 2014 Polar Vortex 4–12"
Jan 6–8, 2014

Extreme cold gripped the state with wind chills plunging below -50°F across northern Montana. Schools statewide closed for multiple days. The event was notable for the duration and intensity of the cold rather than the snow.

November 2014 Arctic Outbreak 8–24"
Nov 10–14, 2014

An early-season Arctic blast brought heavy snow and extreme cold simultaneously. Billings saw temperatures plunge to -25°F and the western mountains received over 2 feet. Schools across the state closed.

December 2003 Western Montana Storm 18–48" (western mountains)
Dec 17–19, 2003

A prolonged Pacific storm buried western Montana. Missoula received over 20 inches and higher elevations exceeded 4 feet. Schools in the Flathead and Missoula valleys closed for multiple days and avalanche danger shut down mountain passes.

February 2019 Cold Snap & Snow 6–18"
Feb 4–9, 2019

A prolonged Arctic outbreak brought dangerously cold temperatures and persistent snow across Montana. Havre and Glasgow recorded over a week of below-zero highs. Schools across northern and central Montana closed repeatedly, with some districts shutting down for the better part of the week.

Snow Day FAQ

How many snow days does Montana get per year?

Western mountain communities often close 6–15 times. The central and Hi-Line regions average roughly 4–8 closures. Eastern Montana sees 3–7. Extreme cold closures add significantly to the count, especially in the north.

Will school be closed tomorrow in Montana?

It depends on the forecast, storm timing, and local road conditions. Enter your ZIP code above to see the latest closure and delay probabilities for your area. Predictions update automatically as National Weather Service forecasts change.

What triggers a snow day in Montana?

Mountain districts may stay open with 6+ inches due to preparedness, but road closures over passes force closures regardless of local conditions. Prairie districts close for blowing snow and visibility as much as accumulation. Wind chills below -25°F to -30°F trigger closures statewide.

Does Montana use virtual snow days?

Montana allows remote instruction at district discretion. Adoption is growing, but many rural districts face significant broadband challenges. Districts that routinely lose 8+ days per year are most likely to have virtual options. Traditional makeup days and calendar buffers remain common.

Which part of Montana gets the most snow?

The western mountains near Glacier National Park and the Yellowstone region receive the most, with some locations exceeding 200 inches per year. West Yellowstone averages roughly 144 inches. Among larger cities, Bozeman and Butte consistently rank among the snowiest.

Snow Day Forecasts by State

Check snow day probabilities for your area. We track school closures, weather alerts, snowfall reports, and 7-day forecasts for all 50 states — from lake-effect blizzards in the Midwest to rare southern snow events.

Great Lakes & Midwest

Lake-effect snow drives some of the highest school closure rates in the country. Michigan, Minnesota, and Wisconsin regularly see multi-day storms, while Ohio, Indiana, and Illinois face both lake-effect bands and arctic cold fronts. The region averages more snow days per year than nearly anywhere else in the U.S.

Northeast & New England

Nor'easters and coastal storms make the Northeast a snow day hotspot. From Buffalo's lake-effect events to Boston's blizzards and Vermont's mountain snowfall, winter weather closures are a regular part of the school year. Major metros like New York City and Philadelphia see widespread closures when storms hit during commute hours.

Northern Plains & Rockies

Blizzards, high-altitude snowfall, and extreme cold define winter across this region. Mountain passes in Colorado, Utah, and Montana can receive over 200 inches annually, while plains states face wind-driven whiteouts that close schools even with modest accumulations. Wind chill regularly triggers closures across the Dakotas and Nebraska.

Appalachia & Mid-Atlantic

Moderate snowfall totals here mask outsized disruption. With lower preparedness and fewer plows, a 3-inch storm in Virginia or North Carolina can close as many schools as a 10-inch storm in the Northeast. Ice storms are especially dangerous across the Appalachian range, often causing multi-day closures.

South & Gulf States

Snow is rare across the Deep South and Gulf Coast, but when it arrives, it's a regional event. Minimal winter infrastructure means even a dusting can trigger widespread school closures. Ice storms pose the biggest winter threat, and states like Texas and Georgia can see citywide shutdowns from storms that would barely register further north.

West Coast & Pacific

Winter weather varies enormously across the West. Alaska sees months of snow and extreme cold, while Pacific Northwest cities face occasional ice storms and wet snow. Mountain areas from the Cascades to the Sierra Nevada measure snowfall in feet. Desert Southwest states rarely see snow at lower elevations.
