Powered by NOAA / National Weather ServiceGriffin Academy High is a high school in Vallejo, California, part of Griffin Academy High 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 Griffin Academy High are almost always made at the district level. If Griffin Academy High District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Griffin Academy High District 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.
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.
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.
