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. Five factors, each scored on its own, then combined into a single probability.

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 Two Factors Hit Together

Superintendents do not look at factors one at a time, and neither does our snow day calculator. Freezing rain on its own is manageable. Freezing rain with sub-freezing pavement creates black ice, one of the most common reasons districts close schools even with little snow. Heavy snow alone is a plowing problem. Heavy snow with 25 mph winds creates whiteout conditions, and no district sends buses into a whiteout. When those combinations appear, the score jumps hard. That is intentional.

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

Diesel fuel starts to gel around 15°F, clogging filters and preventing buses from starting. Moisture inside air brake lines can also freeze, leaving districts without enough buses before routes even begin.

Road Salt Has a Hard Floor

Road Safety

Rock salt loses most of its melting power below 15°F. While magnesium or calcium chloride can help, they are expensive and many districts cannot maintain enough supply during extended cold weather.

Wind Puts the Snow Back

Visibility

Winds above 25 mph blow snow back onto cleared roads, creating drifts and blind intersections. Large school buses need clear visibility and extra turning space to operate safely.

Cold Alone Closes Schools

Student Safety

Wind chills below -20°F can freeze exposed skin in under thirty minutes. Districts may cancel school even on clear mornings to protect students waiting at unsheltered bus stops.

Built for the Morning Window

Predictions focus on the critical 3 AM to 9 AM period when districts decide whether school buses can safely operate.

Frequently Asked Questions

Will I have a snow day tomorrow? −
Enter your city or ZIP code above and you will have a percentage in about two seconds. The predictor looks at the 3 AM to 9 AM window, which is when your district actually decides. Anything at 70% or higher means serious winter weather is on the way. Your district still makes the final call.
Is the Snow Day Predictor free? +
Yes, and it stays free. No account, no sign-up, no paywall. It runs in any browser on any device.
How accurate is the Snow Day Predictor? +
The snow day predictor scores weather, not district decisions. A well-defined storm often tracks closely with what school districts actually do, while a storm that shifts after midnight can produce different outcomes. For the most reliable prediction, check between 7 PM and 10 PM the night before.
How is the snow day predictor different from a weather app? +
A weather app tells you how much snow is coming. It does not tell you whether your school will close. Six inches in Minnesota is a normal Tuesday. Two inches in Georgia shuts everything down. The snow day predictor scores conditions the way a superintendent would.
Does the Snow Day Predictor work for Canadian cities? +
Yes. Enter a Canadian postal code and it pulls live local weather using the same five-factor scoring it uses across the United States.
