Five-Factor Scoring

Snowfall carries the most weight at 35%, combined with temperature, wind speed, wind chill, and storm conditions for a precise location-specific probability.

Hourly Data Refresh

Weather data updates every hour via live OpenWeatherMap feeds. Check back after 7 PM for the most reliable overnight forecast.

🎓

Morning Crunch Window

Predictions target the 3 AM to 9 AM forecast window that actually determines whether buses can run safely. Not a full-day average.

Frequently Asked Questions

Everything you need to know about our Snow Day Predictor and Calculator

The algorithm scores snowfall accumulation at up to 35%, temperature at 20%, wind speed at 15%, wind chill at 15%, and active storm condition codes at 15%. Every factor is scored independently then combined into one probability percentage. That is why two cities with identical snowfall totals can show different predictions when one has dangerous wind chill and the other does not.

There are four tiers. Seventy percent or above means schools are likely closed due to significant winter weather. Between 40% and 69% means delays are possible and conditions are uncertain. Between 15% and 39% means schools will probably stay open despite minor weather. Below 15% means no meaningful winter weather factors are present in the forecast for your location.

School closure decisions belong to district superintendents, not weather data. A storm can meet every severe threshold in the algorithm and a district can still choose a two hour delay based on staffing, road treatment schedules, or local policy. The 99% cap reflects that reality. The tool gives you the strongest possible weather signal. The final call is always the district's.

Weather data refreshes every hour through a live feed from OpenWeatherMap. A storm tracking 200 miles away at 9 PM can shift track, accelerate, or weaken significantly by 5 AM. The most reliable times to check are between 7 PM and 10 PM the evening before, when overnight forecast models have stabilized, or after 5 AM on the morning itself when radar data is real rather than projected.

Yes. The tool covers cities across both the United States and Canada. Enter a US ZIP code or a Canadian postal code and the predictor pulls live local weather data for that exact location. The algorithm applies the same five factor scoring system regardless of which country your city is in, and predictions refresh hourly throughout storm season.
