Powered by NOAA / National Weather ServiceSigourney Jr-Sr High Sch is a high school in Sigourney, Iowa, part of Sigourney Comm 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 Sigourney Jr-Sr High Sch are almost always made at the district level. If Sigourney Comm School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Sigourney 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.
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.
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.
This is an independent forecast, not an official announcement. Confirm any closure with Sigourney Comm School District before acting on it.
