Snow day forecast for Cook County Senior High

Cook County Senior High is a high school in Grand Marais, Minnesota, part of Cook County Public 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 Cook County Senior High are almost always made at the district level. If Cook County Public Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Cook County Public Schools forecast).

Rural area — what that means for closures

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.

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.

Minnesota averages about 54 inches of snow per year. Minnesota schools are built for winter but close for blizzard warnings and extreme wind chill events below -35°F.

How this prediction is calculated

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 Cook County Public Schools before acting on it.
