How well can the network see Kuna?
The nearest Doppler radar is KCBX (Boise, ID), 8.8 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 Kuna its center is about 440 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 Kuna, so low-level rotation and the leading edge of a gust front show up on it. Kuna is closer to its radar than 96% of US cities.
The closest instrument actually measuring the air is KMAN · Nampa Muni on the ASOS/AWOS network, 7.1 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 Idaho observing network as of this build.
