How well can the network see Perry?
The nearest Doppler radar is KBUF (Buffalo, NY), 40 miles to the WNW. 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 Perry its center is about 2,700 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Perry to show rotation in the part of a storm where tornadoes actually form. Perry is closer to its radar than 56% of US cities.
The closest instrument actually measuring the air is KDSV · Dansville Muni on the ASOS/AWOS network, 18 miles away. Far enough that "current conditions" for Perry 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 New York observing network as of this build.
