Why We Built SnowDay Predictor Canada
Every winter evening, Canadian families ask the same question: will there be a snow day tomorrow? Forecasts list snowfall and temperature, but they rarely explain what that means for buses and school.
SnowDay Predictor Canada was built to answer that in plain language. It reads the forecast for your location, scores four winter-weather factors and shows the numbers behind the result, so you can plan the evening before and check again in the morning.
It stays independent on purpose. The score is a planning tool, and the final call always belongs to your school board and bus provider.

How We Turn a Forecast Into a Snow Day Score
- Step 1. We fetch the forecast. Your city, postal code or device location is matched to a WeatherAPI forecast, with OpenStreetMap Nominatim used for postal codes.
- Step 2. We score four factors. Snowfall (up to 40 points), snow chance (up to 30), minimum temperature (up to 20) and winter conditions (up to 10).
- Step 3. We show a plain label. The 0–100 score becomes Very Low, Low, Moderate or High Chance, with an hourly view of the 6–9 AM commute.
- Step 4. We send you to official sources. Your school board, bus provider and Environment Canada confirm closures and warnings. Read the full method.

We show how the score works, name where the data comes from, and send you to the official sources that decide closures.
Published, Explainable Method
Every score uses four weather factors with fixed point limits. Nothing is hidden behind a black box.
