How well can the network see Leitchfield?
The nearest Doppler radar is KLVX (Louisville, KY), 39 miles to the NNE. 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 Leitchfield its center is about 2,500 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Leitchfield to show rotation in the part of a storm where tornadoes actually form. Leitchfield is closer to its radar than 58% of US cities.
The closest instrument actually measuring the air is KI93 · Hardinsburg/Breckinridge Cnty on the ASOS/AWOS network, 22 miles away. Far enough that "current conditions" for Leitchfield 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 Kentucky observing network as of this build.
