How well can the network see Marion?
The nearest Doppler radar is KPAH (Paducah, KY), 42 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 Marion its center is about 2,800 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Marion to show rotation in the part of a storm where tornadoes actually form. Marion is closer to its radar than 53% of US cities.
The closest instrument actually measuring the air is KGDA · Marion/Crittenden Cnty on the ASOS/AWOS network, 1.6 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.
