Powered by NOAA / National Weather ServiceDedham High is a high school in Dedham, Massachusetts, part of Dedham 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 Dedham High are almost always made at the district level. If Dedham Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Dedham 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.
Massachusetts averages about 48 inches of snow per year. Massachusetts districts decide independently but often follow regional patterns during major nor'easters. Boston has closed less than 10 times in recent years.
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 Dedham Schools before acting on it.
