Closure decisions for Cowden-Herrick Grade School are almost always made at the district level. If Cowden-Herrick CUSD 3A Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Cowden-Herrick CUSD 3A Schools forecast).
Rural districts run the longest bus routes over the least-treated roads, so they typically close at lower snowfall totals than nearby urban districts — often on forecasts that would leave a city district open.
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 Cowden-Herrick CUSD 3A Schools before acting on it.
