Snow day forecast for Frederick Douglass Mastery CS

Frederick Douglass Mastery CS is a school in Philadelphia, Pennsylvania, part of Frederick Douglass Mastery CS 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 Frederick Douglass Mastery CS are almost always made at the district level. If Frederick Douglass Mastery CS Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Frederick Douglass Mastery CS Schools forecast).

Urban area — what that means for closures

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.

Pennsylvania averages about 35 inches of snow per year. Erie and northeastern PA see heavy lake-effect snow, while Philadelphia-area districts close more preemptively. Pittsburgh splits the difference.

How this prediction is calculated

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 Frederick Douglass Mastery CS Schools before acting on it.
