Powered by NOAA / National Weather ServiceSisson is a school in Mount Shasta, California, part of Mt. Shasta Union Elementary 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 Sisson are almost always made at the district level. If Mt. Shasta Union Elementary Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Mt. Shasta Union Elementary Schools forecast).
Town districts sit between urban and rural conditions: main routes are usually cleared early, but outlying pickups can stay hazardous well past sunrise.
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 Mt. Shasta Union Elementary Schools before acting on it.
