Powered by NOAA / National Weather ServiceMcCall-Donnelly High School is a high school in McCall, Idaho, part of McCall-Donnelly Joint School District. 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 McCall-Donnelly High School are almost always made at the district level. If McCall-Donnelly Joint School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the McCall-Donnelly Joint School District 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.
Idaho averages about 44 inches of snow per year. Mountain communities and valley districts have very different closure thresholds. Boise closes less often than northern Idaho.
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 McCall-Donnelly Joint School District before acting on it.
