Closure decisions for Grass Ranch Colony High School - 15 are almost always made at the district level. If Kimball School District 07-2 closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Kimball School District 07-2 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.
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.
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.
This is an independent forecast, not an official announcement. Confirm any closure with Kimball School District 07-2 before acting on it.
