How well can the network see Waterville?
The nearest Doppler radar is KGYX (Portland, ME), 54 miles to the SSW. 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 Waterville its center is about 3,900 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Waterville to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KWVL · Waterville/Lafleur Arpt on the ASOS/AWOS network, 1.3 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
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 Maine observing network as of this build.
