Doppler weather radar shows interference from 5 Ghz networks (https://en.wikipedia.org/wiki/Dynamic_frequency_selection), but is not used in chunks of the US (don’t even exist on the west coast), but is critical in places with lots of rain storms (south, northeast, midwest).

What's your source for areas of the U.S. without doppler? It looks like NEXRAD dopplers are "everywhere" in the U.S.

It's not for NEXRAD. The frequencies in question are used for Terminal Doppler Weather Radar (TDWR), which is a special radar used for detecting windshear and higher resolution precipitation data at select airports.
