How well can the network see Lehi?
The nearest Doppler radar is KMTX (Salt Lake City, UT), 66 miles to the NNW. 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 Lehi its center is about 5,200 ft above ground. That is far enough out that the beam has climbed above the lowest few thousand feet. Storm structure aloft is visible; a shallow circulation near the ground may not be, and a warning here can arrive before anything looks dramatic on the radar picture.
The closest instrument actually measuring the air is KSVR · Salt Lake City/South Valley Rgnl on the ASOS/AWOS network, 15 miles away. Far enough that "current conditions" for Lehi 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 Utah observing network as of this build.
