How well can the network see Corning?
The nearest Doppler radar is KBBX (Beale AFB, CA), 42 miles to the SE. 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 Corning its center is about 2,800 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Corning to show rotation in the part of a storm where tornadoes actually form. Corning is closer to its radar than 53% of US cities.
The closest instrument actually measuring the air is KRBL · Red Bluff Muni on the ASOS/AWOS network, 16 miles away. Far enough that "current conditions" for Corning 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 California observing network as of this build.
