How well can the network see Parma?
The nearest Doppler radar is KCLE (Cleveland, OH), 7.1 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 Parma its center is about 350 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 Parma, so low-level rotation and the leading edge of a gust front show up on it. Parma is closer to its radar than 97% of US cities.
The closest instrument actually measuring the air is KCLE · Cleveland/Hopkins Intl on the ASOS/AWOS network, 6.6 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.
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 Ohio observing network as of this build.
