How well can the network see Lamar?
The nearest Doppler radar is KSGF (Springfield, MO), 51 miles to the ESE. 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 Lamar its center is about 3,700 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Lamar to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KPTS · Pittsburg/Atkinson Muni on the ASOS/AWOS network, 25 miles away. Far enough that "current conditions" for Lamar 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 Missouri observing network as of this build.
