How well can the network see Berlin?
The nearest Doppler radar is KGRB (Green Bay, WI), 55 miles to the NE. 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 Berlin its center is about 4,100 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 KY50 · Wautoma Muni on the ASOS/AWOS network, 18 miles away. Far enough that "current conditions" for Berlin 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 Wisconsin observing network as of this build.
