How well can the network see Villa Park?
The nearest Doppler radar is KLOT (Chicago, IL), 20 miles to the SSW. 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 Villa Park its center is about 1,100 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 Villa Park, so low-level rotation and the leading edge of a gust front show up on it. Villa Park is closer to its radar than 85% of US cities.
The closest instrument actually measuring the air is KORD · Chicago/O'Hare Intl on the ASOS/AWOS network, 5.7 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 Illinois observing network as of this build.
