Closure decisions for Horizon Elementary - 09 are almost always made at the district level. If Harrisburg School District 41-2 closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Harrisburg School District 41-2 forecast).
Urban districts usually have the best-treated roads and the shortest bus routes, so they tend to hold out longer before closing — but they also weigh sidewalk conditions and transit reliability for students who walk or ride public transport.
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.
