Upper air over Boise

The nearest radiosonde launch is Boise, about 4 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.
