How well can the network see Graymoor-Devondale?
The nearest Doppler radar is KLVX (Louisville, KY), 27 miles to the SW. 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 Graymoor-Devondale its center is about 1,600 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 Graymoor-Devondale, so low-level rotation and the leading edge of a gust front show up on it. Graymoor-Devondale is closer to its radar than 75% of US cities.
The closest instrument actually measuring the air is KLOU · Louisville/Bowman Fld on the ASOS/AWOS network, 3.9 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
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.
