How well can the network see Greenbrier?
The nearest Doppler radar is KOHX (Nashville, TN), 17 miles to the SE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Greenbrier its center is about 960 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Greenbrier, so low-level rotation and the leading edge of a gust front show up on it. Greenbrier is closer to its radar than 88% of US cities.
The closest instrument actually measuring the air is KJWN · Nashville/Tune Arpt on the ASOS/AWOS network, 17 miles away. Far enough that "current conditions" for Greenbrier is an educated reading of somewhere else, worth knowing before you plan around a single temperature.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Tennessee observing network as of this build.
