I've given up on Garmin ever improving their weather features after two decades, they won't even fetch updates via WiFi, only phone connection which is incredibly lazy and stupid
However it seems critical as weather gets worse and worse, more dramatic with climate change, far more wind and urban temps much warmer than airport temps to increase the number of locations used
I would never expect them to use civilian networks with random sensors like weather-underground and
But there are other options more than NWS, which for me is 25 miles away and WILDLY inaccurate compared to my local ubran weather
There is a national network in the USA that is very professional and associated often with Governments and Universities called WEATHERSTEM and has professional grade sensors

ALL THEIR DATA IS OPEN SOURCE

Garmin could easily double if not quadruple the number of quality weather locations and "cells" by adding WeatherSTEM

I am pretty sure that Garmin suggestion link is a black hole that is never ever reviewed, forget acted on, as I've worked other corporate and know they don't give a damn about public feedback like that, but I will send this there anyway and hope others will as well
