Iowa Snow Day Forecast & School Closings

Snow Days per Year3–12 (varies by region)
Snow SeasonNovember through March

Iowa's flat terrain and exposure to both Arctic air masses and Gulf moisture make it one of the most blizzard-prone states in the country. Annual snowfall ranges from about 25 inches in the southeast to over 40 inches in the northwest, but the real story is wind — Iowa's open prairies turn even moderate snow into whiteout conditions. With over 300 school districts spread across a largely rural landscape, closure decisions are often driven as much by road visibility as by accumulation.

Snow Zones in Iowa

Northwest Iowa 36–46"/yr

Sioux City, Spencer, and the northwest corner receive the most snow in the state, and exposure to open prairie makes blizzards particularly dangerous. Ground blizzards — blowing existing snow with little new accumulation — can reduce visibility to near zero. Schools close 5–10 times per year.

Northeast Iowa & Driftless Area 36–45"/yr

Dubuque, Decorah, and the hilly Driftless Area. The rugged terrain is unusual for Iowa and creates hazardous driving conditions when combined with snow and ice. Elevation differences mean snowfall varies dramatically over short distances. Schools close 5–8 times per year.

Central Iowa 30–38"/yr

Des Moines, Ames, and Waterloo. The largest concentration of students and the most-watched closure decisions. Districts close 3–6 times per year. Major blizzards tracking northeast from Kansas and Nebraska often hit central Iowa hardest.

Southeast Iowa & River Corridor 25–33"/yr

Davenport, Iowa City, and the Mississippi River corridor. The least snow in the state, with storms often transitioning to freezing rain along the rain-snow line. Ice storms are frequently more disruptive than snow. Schools close 3–5 times per year.

Notable Winter Storms

Blizzard of 1975 8–14"
Jan 10–12, 1975

One of Iowa's deadliest storms. Moderate snow combined with 50+ mph winds and sudden temperature drops created whiteout conditions. Schools across the state were closed for days and some rural areas were isolated for nearly a week.

February 2011 Groundhog Day Blizzard 10–20"
Feb 1–2, 2011

Heavy snow with blizzard conditions swept across Iowa from southwest to northeast. Des Moines received over 14 inches and wind gusts exceeded 40 mph. Schools statewide closed for 1–2 days.

January 2014 Polar Vortex 3–10"
Jan 6–8, 2014

Extreme cold shut down schools statewide for multiple days. Wind chills plunged to -40°F to -50°F across northern Iowa. Many districts closed for dangerous cold even in areas with minimal snow.

December 2009 Blizzard 8–18"
Dec 23–25, 2009

A powerful Christmas Eve blizzard hit the state with heavy snow and high winds. While schools were already on holiday break, the storm stranded travelers and demonstrated how quickly Iowa's flat terrain turns moderate snow into dangerous blizzard conditions.

April 2018 Late-Season Blizzard 8–20"
Apr 13–14, 2018

A rare mid-April blizzard dumped heavy, wet snow across central and northern Iowa. Schools that had planned spring activities were forced to close, and the late-season timing caught many off guard.

Snow Day FAQ

How many snow days does Iowa get per year?

Northwest Iowa averages 5–10 closure days per year. Central Iowa including Des Moines sees 3–6. Southeast Iowa typically has 3–5. Wind-driven closures add days that raw snowfall totals don't capture.

Will school be closed tomorrow in Iowa?

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 Iowa?

Most Iowa districts close for 3–4 inches of forecast snow, but wind and visibility are often bigger factors. Blowing snow with near-zero visibility on rural roads can trigger closures even with minimal accumulation. Wind chill below -35°F is an independent closure trigger for most districts.

Does Iowa use virtual snow days?

Iowa allows districts to apply for permission to use virtual instruction days. Adoption has grown since COVID, but many rural districts face broadband challenges that limit virtual options. Some districts use a hybrid approach with a few virtual days supplemented by traditional makeup days.

Why does Iowa close schools for wind even without much snow?

Iowa's flat, open terrain creates extreme ground blizzard conditions. Wind can blow existing snow off fields and across roads, reducing visibility to near zero even on a sunny day. Rural bus routes become extremely dangerous in these conditions, and many districts close based on road visibility reports rather than snowfall forecasts alone.

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.
