How well can the network see Millcreek?
The nearest Doppler radar is KMTX (Salt Lake City, UT), 51 miles to the NW. 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 Millcreek its center is about 3,700 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Millcreek to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KSLC · Salt Lake City Intl on the ASOS/AWOS network, 9.1 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 Utah observing network as of this build.
