How well can the network see Lock Haven?
The nearest Doppler radar is KCCX (State College, PA), 32 miles to the WSW. 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 Lock Haven its center is about 2,000 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Lock Haven to show rotation in the part of a storm where tornadoes actually form. Lock Haven is closer to its radar than 67% of US cities.
The closest instrument actually measuring the air is KUNV · State College/Univ Park Arpt on the ASOS/AWOS network, 28 miles away. Far enough that "current conditions" for Lock Haven 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 Pennsylvania observing network as of this build.
