How well can the network see Hanover Park?
The nearest Doppler radar is KLOT (Chicago, IL), 26 miles to the S. 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 Hanover Park 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 Hanover Park, so low-level rotation and the leading edge of a gust front show up on it. Hanover Park is closer to its radar than 76% of US cities.
The closest instrument actually measuring the air is K06C · Schaumburg Rgnl on the ASOS/AWOS network, 1.9 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 Illinois observing network as of this build.
