Winter in Philadelphia
Philadelphia averages 16 inches of snow a year, according to NOAA’s 1991-2020 climate normals - a occasional snow place. Snow is a few-times-a-year event. Limited equipment means modest amounts cause real disruption.
That is why local snowfall thresholds differ so much from one town to the next: a district that plans for 16 inches a year is equipped differently from one that never sees any. Here, roughly 2 inches in a single storm is where a normal school day comes under threat.
Upper air over Philadelphia
The nearest radiosonde launch is Upton, about 136 miles away. A weather balloon goes up twice a day and measures temperature, humidity and wind all the way through the atmosphere - which is what forecasters actually read to judge whether storms will fire, and how a surface forecast was arrived at.
