Winter in Portland
Portland averages 69 inches of snow a year, according to NOAA’s 1991–2020 climate normals — a heavy snow place. Serious winters and the equipment to match. It takes a genuinely big storm to close school.
That is why local snowfall thresholds differ so much from one town to the next: a district that plans for 69 inches a year is equipped differently from one that never sees any. Here, roughly 8 inches in a single storm is where a normal school day comes under threat.
Upper air over Portland
The nearest radiosonde launch is Gray, about 16 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.
