Ground based meteorological radars are either S-Band (2.7-2.9 GHz) for very long ranges, C-Band (5.6-5.65 GHz) for ranges of 200 km or so, or X-Band for near range stuff. Apart from the fact that there's no frequency overlap mobile phone tower antennas are tilted down so that they point at the punters carrying their mobile devices. Weather radars on the other hand tend to point up 'cause that's where the weather is.
Airborne weather radars tend to point down for most of the cruise and a little up when at lower altitudes.
5g uses a variety of frequencies not necessarily a single one, each region allocating its own range. Some areas have concerns that the higher allocated frequencies will impinge on satellite rainfall radar.
There has already been interference in Hungary with ground based wx radar although not connected with 5g it showed an inadequate consultation process

This is an honest open query about possible overlap with airborne weather radar.
