Snow Day Predictor uses current hourly forecast data from Tomorrow.io and evaluates tomorrow in the forecast location's local time.
Snow Day Predictor is a free snow predicting tool for checking tomorrow’s snow forecast by U.S. ZIP code. Using forecast data from Tomorrow.io, it evaluates expected snowfall, timing, snow intensity, temperature, precipitation, sleet, and freezing rain to turn detailed hourly conditions into a clear, location-specific result.
The snowfall forecast is organized around the forecast location’s local calendar day and includes a categorical, weather-based school closure outlook for winter weather planning. Forecasts can change, and conditions may vary within a ZIP code. School closure outlooks are estimates based on weather conditions only not official announcements from a school, district, authority, or organization.

Transparent forecast guidance
Snow Day Predictor focuses on tomorrow for practical, near-term planning, but no weather forecast can guarantee an exact outcome. Tomorrow.io forecasts can update as observations and model guidance change, so a later request may produce a different result.

Snow Day Predictor is a planning tool, not an official announcement.
Actual closures and delays are decided by the relevant school, district, authority, or organization. Confirm an official announcement before making attendance or transportation decisions. The Terms of Use explain these limitations in more detail.

Clear answers
Enter a 5 digit U.S. ZIP code.
