Powered by NOAA / National Weather ServiceMarshall High is a high school in Falls Church, Virginia, part of Fairfax County Public 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 Marshall High are almost always made at the district level. If Fairfax County Public Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Fairfax County Public Schools forecast).
Suburban districts depend heavily on bus fleets covering a wide area of residential streets, which are plowed after main roads. Side-street conditions at 5 AM often decide the call.
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.
Virginia averages about 15 inches of snow per year. Virginia districts vary widely — NoVA follows DC patterns while mountain districts like those near Charlottesville handle more snow before closing.
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.
