Winter in Columbus
Columbus averages 28 inches of snow a year, according to NOAA’s 1991-2020 climate normals - a moderate snow place. A handful of accumulating storms a year. Districts close for the larger ones.
That is why local snowfall thresholds differ so much from one town to the next: a district that plans for 28 inches a year is equipped differently from one that never sees any. Here, roughly 4 inches in a single storm is where a normal school day comes under threat.
Upper air over Columbus
The nearest radiosonde launch is Wilmington, about 57 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.
