there is no overlap. As I've already said airborne weather radars are X-Band and typically in the 9.3 GHz range. 5G will use two frequency bands; Frequency range 1, which is
less than 6 GHz and typically around 3.5 GHz, and Frequency range 2 which is
greater than 24 GHz. You'll note that 9.3 GHz is greater than 6 GHz and markedly less than 24 GHz,
ie no overlap.
Bear in mind that one of the key issues with 5G is signal attenuation; the effective range between a base station and a device, both specifically designed to exchange data on the 5G spectrum, is measured in hundreds of metres. How anyone thinks that signal is going to be interfering with other devices well off frequency and at considerable distances is anyone's guess.
In any event, all the hoopla to date has been in relation to ground-based weather radar and weather satellite water vapour detection using 23.8 GHz emissions (which is close to the minimum range of 5G FR2).
