Hyper-local snow-day odds tuned to the 4–5 AM school-closure call.
What Snow Day Alerts does
Enter a ZIP code to see an estimate of snow-day disruption risk for the next five school days. The percentage is a planning signal based on forecast conditions that often lead to closures — especially overnight snow/ice and morning-commute conditions.
How to interpret the percent
70% doesn’t mean “guaranteed closed.” It means conditions look similar to past mornings where closures/delays were more likely. Districts still vary based on plows, buses, staffing, and local road conditions.
- Best time to check: the evening before and again around 4–6 AM.
- Not official: always rely on your district’s alerts for final decisions.
- More detail: see How It Works and FAQ.
What we look at (high level)
- Overnight snow & ice: accumulation and freezing conditions before buses roll.
- Morning timing: conditions between roughly midnight–noon matter most.
- Wind & cold: strong gusts and dangerous cold can push delays/closures.
Data sources & limitations
- Forecast data is provided by modern weather APIs (e.g., Open-Meteo).
- ZIP geocoding uses OpenStreetMap/Nominatim.
- Forecasts can shift quickly; local roads, staffing, and policies can override weather.
