Powered by NOAA / National Weather ServiceHi-Line Colony School is a school in Chester, Montana, part of Chester-Joplin-Inverness El Schools. 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 Hi-Line Colony School are almost always made at the district level. If Chester-Joplin-Inverness El Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Chester-Joplin-Inverness El 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.
Montana averages about 57 inches of snow per year. Montana school districts are spread across vast distances. Western mountain communities close more for heavy snowfall while eastern plains districts close for blizzard conditions and extreme cold.
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 Chester-Joplin-Inverness El Schools before acting on it.
