How well can the network see Osage?
The nearest Doppler radar is KARX (La Crosse, WI), 89 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 Osage its center is about 8,100 ft above ground. At that range the beam overshoots the layer where severe weather organizes. The radar is describing the middle of the storm, not its base , which is why a warning for Osage can look unsupported on the mosaic and still be right. Trust the warning over the picture.
The closest instrument actually measuring the air is KCCY · Charles City/NE Iowa Rgnl on the ASOS/AWOS network, 18 miles away. Far enough that "current conditions" for Osage 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 Iowa observing network as of this build.
