How well can the network see Gallipolis?
The nearest Doppler radar is KRLX (Charleston, WV), 43 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 Gallipolis its center is about 2,900 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Gallipolis to show rotation in the part of a storm where tornadoes actually form. Gallipolis is closer to its radar than 51% of US cities.
The closest instrument actually measuring the air is KJRO · Jackson/Rhodes Arpt on the ASOS/AWOS network, 24 miles away. Far enough that "current conditions" for Gallipolis 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 Ohio observing network as of this build.
