This map is a comparison tool, not a comprehensive list of every city and not an official school-closure map. Later-day and local district decisions can differ from weather-only signals.

How to read the Snow Day Risk Map

The map compares where winter conditions are most likely to disrupt school travel tomorrow across the selected watch markets.

  • Closure and delay remain separate probabilities in the detail panel.
  • Disruption risk is the combined closed-or-delayed planning signal used to color map markers.
  • Snow, ice/refreeze, extreme cold, wind, visibility, storm timing, prior-day accumulation, and active US NWS winter alerts can all affect the estimate.
  • The map compares a fixed watch list of snow-prone markets; use the calculator below for any supported city, ZIP code, or Canadian postal code.

Data and limitations

The map uses the same baseline model as the main calculator and a shared cache so it does not make a fresh upstream weather request for every visitor. Passive map checks are not written into the accuracy dataset; only visitor-requested calculator predictions are logged for later verification.

Weather data: Open-Meteo. US official winter alerts: National Weather Service when available.
