Winter in Pittsburgh
Pittsburgh averages 44 inches of snow a year, according to NOAA’s 1991–2020 climate normals — a regular snow place. Snow several times a winter, well-practised response. Closures happen but need a real storm.
That is why local snowfall thresholds differ so much from one town to the next: a district that plans for 44 inches a year is equipped differently from one that never sees any. Here, roughly 6 inches in a single storm is where a normal school day comes under threat.
Upper air over Pittsburgh
The nearest radiosonde launch is Pittsburgh, about 14 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.
