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.
