Powered by NOAA / National Weather ServiceUpper Darby SHS is a school in Drexel Hill, Pennsylvania, part of Upper Darby SD 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 Upper Darby SHS are almost always made at the district level. If Upper Darby SD Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Upper Darby SD 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.
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.
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 Upper Darby SD Schools before acting on it.
