South Dakota Snow Day Forecast & School Closings
South Dakota's snow day patterns are defined by the contrast between the Black Hills — a mountainous island rising from the plains with the state's heaviest snowfall — and the vast prairies where blowing snow and extreme cold are often more disruptive than accumulation. Sioux Falls in the east averages roughly 42 inches per year, while Lead in the Black Hills can exceed 150 inches. The state's rural character and long bus routes make it one of the more closure-prone states in the northern plains.

Snow Zones in South Dakota
Lead, Deadwood, and Spearfish. The highest terrain in the state creates dramatically heavier snowfall than the surrounding plains. Lead at nearly 5,200 feet averages over 150 inches. Rapid City at the foothills sees less but still catches Black Hills-enhanced storms. Schools in the hills close roughly 5–10 times per year.
Aberdeen, Watertown, and the northern tier. Open prairie terrain means blowing and drifting snow can make roads impassable with modest accumulations. Arctic air masses bring extreme cold. Schools close roughly 4–8 times per year, with wind chill closures common.
Pierre, Mitchell, and the central corridor along the Missouri River. Moderate snowfall but exposed terrain. Pierre's position on the Missouri provides some sheltering. Schools close roughly 3–6 times per year.
Sioux Falls, Brookings, and the Minnesota border region. The highest concentration of students in the state. Heavier snow than central SD due to moisture from the east. Schools close roughly 3–6 times per year, typically for larger systems or blizzard conditions.

Notable Winter Storms
An extremely early-season blizzard devastated western South Dakota. The Black Hills received 4+ feet of heavy, wet snow with trees still in leaf. Tens of thousands of cattle perished. Schools closed for multiple days and some communities lost power for over a week.
A catastrophic blizzard with 70+ mph winds paralyzed the state for 3 days. Some of the worst conditions were in central and eastern SD. Schools closed statewide for up to a week and rural communities were isolated for days.
Extreme cold with wind chills below -40°F to -50°F shut down schools across the state. Aberdeen recorded wind chills approaching -60°F. Closures were driven entirely by dangerous cold rather than accumulation.
A late-season blizzard brought heavy snow and blizzard conditions to central and eastern South Dakota. Schools that had planned spring activities were forced to close, and the storm's mid-April timing caught many off guard.
Snow Day FAQ
How many snow days does South Dakota get per year?
The Black Hills average roughly 5–10 closure days. Northern plains communities see 4–8. Sioux Falls and the southeast average 3–6. Extreme cold closures add significantly to the count across all regions.
Will school be closed tomorrow in South Dakota?
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 South Dakota?
Wind and visibility are often more important than accumulation. Most districts close when roads become impassable from blowing snow. Wind chills below -35°F trigger closures statewide. When accumulation drives closures, 4+ inches with wind is a common threshold.
Does South Dakota use virtual snow days?
South Dakota allows remote learning at district discretion. Sioux Falls and Rapid City have adopted virtual options, but many rural districts face broadband challenges. Calendar buffers and traditional makeup days are still the primary approach in much of the state.
Which part of South Dakota gets the most snow?
The Black Hills receive by far the most. Lead at the upper elevations averages roughly 155 inches per year — more than triple what Sioux Falls sees. The northern plains around Aberdeen and Watertown see somewhat more than the central and southeastern regions.
