How well can the network see Wellsville?
The nearest Doppler radar is KPBZ (Pittsburgh, PA), 24 miles to the ESE. 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 Wellsville its center is about 1,400 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 Wellsville, so low-level rotation and the leading edge of a gust front show up on it. Wellsville is closer to its radar than 80% of US cities.
The closest instrument actually measuring the air is K2G2 · Steubenville/Jefferson Cnty on the ASOS/AWOS network, 17 miles away. Far enough that "current conditions" for Wellsville 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.
