Closure decisions for South O'Brien Secondary School are almost always made at the district level. If South O'Brien Comm School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the South O'Brien Comm School District 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.
Iowa averages about 35 inches of snow per year. Iowa schools watch wind chill closely — many districts close when wind chill drops below -25°F regardless of snowfall.
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.
