Winter in Washington
Washington averages 10 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 10 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 Washington
The nearest radiosonde launch is Sterling, about 24 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.
