Powered by NOAA / National Weather ServicePreston Jr High School is a middle school in Preston, Idaho, part of Preston Joint 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 Preston Jr High School are almost always made at the district level. If Preston Joint District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Preston Joint 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.
Idaho averages about 44 inches of snow per year. Mountain communities and valley districts have very different closure thresholds. Boise closes less often than northern Idaho.
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 Preston Joint District before acting on it.
