How well can the network see Helotes?
The nearest Doppler radar is KEWX (Austin/San Antonio, TX), 40 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 Helotes its center is about 2,700 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Helotes to show rotation in the part of a storm where tornadoes actually form. Helotes is closer to its radar than 56% of US cities.
The closest instrument actually measuring the air is K5C1 · Boerne/Stage Fld on the ASOS/AWOS network, 10 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 Texas observing network as of this build.
