How well can the network see Coal Valley?
The nearest Doppler radar is KDVN (Davenport, IA), 14 miles to the NNW. 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 Coal Valley its center is about 740 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 Coal Valley, so low-level rotation and the leading edge of a gust front show up on it. Coal Valley is closer to its radar than 92% of US cities.
The closest instrument actually measuring the air is KMLI · Moline/Quad City Intl on the ASOS/AWOS network, 4.4 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 Illinois observing network as of this build.
