How well can the network see Carmi?
The nearest Doppler radar is KVWX (Evansville, IN), 27 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 Carmi 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 Carmi, so low-level rotation and the leading edge of a gust front show up on it. Carmi is closer to its radar than 75% of US cities.
The closest instrument actually measuring the air is KFWC · Fairfield Muni on the ASOS/AWOS network, 24 miles away. Far enough that "current conditions" for Carmi is an educated reading of somewhere else, worth knowing before you plan around a single temperature.
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.
