Closure decisions for Isna Wica Owayawa are almost always made at the district level. If Isna Wica Owayawa Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Isna Wica Owayawa Schools 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.
South Dakota averages about 40 inches of snow per year. South Dakota schools close for blizzard warnings and ground blizzard conditions. Western SD (Black Hills) gets more snow but closes less often.
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.
