Algorithmic Breakdown

The Science of School Closures

A superintendent is not reading a weather app. They are asking one question at 4 AM: can I put a bus full of kids on these roads and get every one of them home safely? Our snow day predictor models that decision. It scores five factors on their own, then adds them into one snow day chance. Each number below is the most that factor can add to your score.

35%

Snowfall

Heavy, fast-falling snow overwhelms road crews and greatly increases school closure chances.

20%

Temperature

Extremely low temperatures reduce road salt effectiveness, making icy roads more dangerous.

15%

Wind Speed

Strong winds reduce visibility and blow snow back onto cleared roads and highways.

15%

Wind Chill

Dangerous wind chills make waiting outdoors unsafe for students and school transportation.

15%

Storm Conditions

Ice storms, blizzards, and freezing rain rapidly create hazardous travel and safety risks.

The Pre-Dawn Window

Timing beats depth. A storm that peaks between 3:00 AM and 9:00 AM is the worst possible storm because road crews never get a clean window to pre-treat, and the heaviest snowfall arrives exactly when school buses are on the road. The same storm arriving at noon? Cleared by morning. Nobody misses school.

When the Factors Stack Up

Superintendents weigh everything at once, and so does our snow day calculator. Each factor adds its own points, so snow, freezing roads, and wind stack up fast. Two inches of snow on a calm 34°F morning scores low. The same two inches at 20°F with 25 mph winds scores more than twice as high. Freezing rain works the same way. Add cold pavement and you get black ice, one of the most common reasons for a school closing even when little snow falls.

Some storms do not need help. Six inches of snow or more, freezing rain, or a wind chill of minus 25°F or colder each set a minimum score, because districts close for those alone. And since there is no school on weekends, from Friday morning on the snow day calculator shows your chance for Monday.

School Transportation

What Actually Stops a School Bus

School closures are not really a weather decision. They are a mechanical one.

Diesel Gels and Air Brakes Freeze

Fleet Safety

Untreated diesel fuel can start to gel around 10 to 15°F, clogging filters and keeping buses from starting. Moisture in air brake lines can freeze too, so a district may run short of working buses before routes even begin.

In your snow day score: the temperature factor

Road Salt Has a Hard Floor

Road Safety

Rock salt loses most of its melting power below about 15°F. Magnesium and calcium chloride work in deeper cold, but they cost more, and many districts cannot keep enough on hand through a long cold snap.

Wind Puts the Snow Back

Visibility

Winds above 25 mph blow snow back onto cleared roads, creating drifts and blind intersections. A school bus needs clear sight lines and extra turning room to run safely.

In your snow day score: the wind speed factor

Cold Alone Closes Schools

Student Safety

Wind chills of minus 20°F or colder can freeze exposed skin in about thirty minutes. Some districts cancel school or call a delay on clear, dry mornings just to protect students waiting at open bus stops.

Frequently Asked Questions

Will I Have a Snow Day Tomorrow? −
Enter your city, ZIP code, or Canadian postal code in the snow day predictor at the top of this page. You will see your town's snow day chance for the next school morning, based on the live forecast for snow, cold, wind, and ice. Your school district still makes the final call, so watch for its announcement.
What Does My Snow Day Percentage Mean? +
The number shows how strongly the weather points toward a school closing. At 70% or higher, schools are likely closed. From 40 to 69%, a delay or closure is possible. From 15 to 39%, schools will probably open. Under 15% means a normal school day.
How Accurate Is the Snow Day Calculator? +
It is as good as the forecast behind it. The snow day calculator scores the same weather that superintendents watch, but it cannot see local road crews, staffing, or district habits. Some districts close for two inches of snow, while others stay open through six. Use the percentage to plan, not as a promise.
When Should I Check My Snow Day Prediction? +
Check after 7 PM the night before, then again early in the morning if a storm is moving in. Forecasts refresh every hour, and an overnight change in snowfall or freezing rain can move your school closing odds quickly.
What Is the Difference Between a Snow Day and a School Delay? +
On a snow day, schools close for the whole day. A delay, often two hours, gives road crews time to clear and treat roads before buses run. Districts usually pick a delay when the worst weather ends early in the morning. In Canada, school boards may also cancel buses while schools stay open.
Is the Snow Day Predictor Free, and Does It Work in Canada? +
Yes to both. The snow day predictor is free with no sign up, and it covers all 50 US states plus 13 Canadian provinces and territories. Search by city, US ZIP code, or Canadian postal code.
