Colour and bar height both show how heavy the rain would look on radar. A dotted line means the model has no reading for that hour, which is not the same as no rain.

How well can the network see Belgrade?
The nearest Doppler radar is KTFX (Great Falls, MT), 117 miles to the N. 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 Belgrade its center is about 12,200 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 Belgrade can look unsupported on the mosaic and still be right. Trust the warning over the picture.
The closest instrument actually measuring the air is KBZN · Bozeman/Gallatin Fld on the ASOS/AWOS network, 1.0 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 Montana observing network as of this build.
