Closure decisions for Mahomet-Seymour High School are almost always made at the district level. If Mahomet-Seymour CUSD 3 Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Mahomet-Seymour CUSD 3 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.
High schools start earliest, so they feel a storm before the rest of the district does — the first buses often roll while roads are still being treated. That earlier start time is one reason a district watching a morning storm may call the day off entirely rather than run a delay.
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 Mahomet-Seymour CUSD 3 Schools before acting on it.
