Chance of a snow day in Chicago
The estimate above is driven by the forecast for this location rather than by generic city-name text. Snow during the early-morning travel window is weighted more heavily than snow that ends earlier, and the model also checks freezing precipitation signals, severe cold, wind gusts, and visibility.
School districts can make different decisions under the same weather conditions. Treat this as planning information and verify the final status with your local school authority.
Chicago school-closure context
Chicago Public Schools says it aims to keep schools open when it is safe, while monitoring conditions that can make attendance dangerous.
- CPS lists air temperature and wind chill, snow and ice, road and building access, heating or power problems, and safe student transportation among its closure factors.
- CPS works with the City of Chicago Office of Emergency Management and Communications on weather-related decision making.
- Families should confirm any closure through CPS official notifications and cps.edu.
Local guidance reviewed September 10, 2026. Official school or district notices always take priority over this estimate.
How this Chicago estimate works
The current baseline model uses live Open-Meteo forecast data. For US locations, active National Weather Service winter alerts are included when available. It does not claim to know a district's historical closure behavior unless verified local data has been added to this page.
