Powered by NOAA / National Weather ServiceNorthbrook School is a school in Mendota, Illinois, part of Mendota CCSD 289 Schools. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for Northbrook School are almost always made at the district level. If Mendota CCSD 289 Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Mendota CCSD 289 Schools forecast).
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 Mendota CCSD 289 Schools before acting on it.
