How well can the network see Orono?
The nearest Doppler radar is KCBW (Houlton, ME), 92 miles to the NNE. 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 Orono its center is about 8,400 ft above ground. At that range the beam overshoots the layer where severe weather organizes. The radar is describing the middle of the storm, not its base , which is why a warning for Orono can look unsupported on the mosaic and still be right. Trust the warning over the picture.
The closest instrument actually measuring the air is KBGR · Bangor Intl Arpt on the ASOS/AWOS network, 7.0 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 Maine observing network as of this build.
