How well can the network see Williamson?
The nearest Doppler radar is KRLX (Charleston, WV), 53 miles to the NE. 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 Williamson its center is about 3,900 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Williamson to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KPBX · Pikeville/Pike Cnty on the ASOS/AWOS network, 18 miles away. Far enough that "current conditions" for Williamson 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 West Virginia observing network as of this build.
