About Snow Day Predictor

School closure decisions are never based on snowfall totals alone, superintendents weigh ice accumulation, overnight low temperatures, wind chill, road treatment status, and even how many consecutive closures a district has already used that year. This predictor builds a fun, weighted estimate from the forecast variables that matter most, giving you a probability rather than a guaranteed answer, since the final call always belongs to your local district.

Snowfall totals alone tell an incomplete story. A light dusting on an already icy road can be more dangerous for bus routes than six inches of dry, powdery snow on clear pavement, which is why districts in snow-heavy regions often stay open through storms that would shut down a district further south. Regional infrastructure and plowing readiness shift the actual threshold for closure dramatically.

This tool exists for the fun of it as much as the forecasting, students checking it the night before a storm, parents trying to plan ahead, but it's built on the same variables meteorologists and school administrators actually look at: expected accumulation, ice risk, temperature, and wind, just weighted into a quick probability score instead of an official decision.

Enter your expected snowfall total, ice accumulation estimate, overnight low temperature, and your general region's typical winter preparedness level. The predictor runs those inputs through a weighted scoring model and returns an estimated percentage chance of a closure.

Checking the forecast for your area shouldn't come with any tracking attached. The prediction is calculated in your browser, and we never receive or log your location. To get a forecast, the tool asks outside services for your approximate location from your IP address and for weather data, so those services see the coordinates or place name it looks up.

FAQ

Frequently asked questions

How does the predictor come up with a percentage?

It weighs expected snowfall, ice accumulation, temperature, wind conditions, and typical regional winter preparedness against common municipal closure thresholds to produce an estimated probability.

Is this an official closure announcement?

No, it's for entertainment and planning purposes only. The actual decision always comes from your local school district superintendent based on real-time conditions.

Why do some districts close for small amounts of snow?

Districts without heavy snow removal infrastructure, common in southern or warmer-climate regions, tend to close far more readily than northern districts equipped with plows, salt trucks, and winter-ready bus fleets.

Does ice matter more than snowfall totals?

Generally yes. Ice creates far more dangerous road and sidewalk conditions for buses and pedestrians than an equivalent depth of dry snow, which is why forecasts with freezing rain tend to push closure probability up sharply.

My school closed even though the predictor gave a low percentage. Why?

The predictor estimates likelihood from forecast data and historical closure patterns, but the actual call comes down to a superintendent weighing factors like road conditions and bus safety on the morning itself, which can go either way even on a borderline forecast.

How far ahead can the predictor actually forecast a snow day?

Accuracy drops the further out you look, since weather forecasts themselves get less reliable beyond about three days. A prediction for tomorrow is far more dependable than one for next week.
