How well can the network see Iosco?
The nearest Doppler radar is KDTX (Detroit, MI), 33 miles to the ENE. 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 Iosco its center is about 2,000 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Iosco to show rotation in the part of a storm where tornadoes actually form. Iosco is closer to its radar than 67% of US cities.
The closest instrument actually measuring the air is KOZW · Howell/Hardy Arpt on the ASOS/AWOS network, 7.3 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 Michigan observing network as of this build.
