Town districts sit between urban and rural conditions: main routes are usually cleared early, but outlying pickups can stay hazardous well past sunrise.
Illinois averages about 38 inches of snow per year. Chicago Public Schools rarely close, but suburban and downstate districts close more frequently for lake-effect and prairie blizzard events.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with Eastern IL Area of Spec Educ Schools before acting on it.
