Oops! I posted a new topic not realizing this one was here, even though I replied to it a while back (my old age!)
Anyway I think this topic is awesome because it encompasses many other threads and we really just need an update dedicated to just weather. So I voted on this topic.
Totally agree with the OP! With all these weather ideas and great suggestions, could Asobo consider dedicating one sim update to weather only? Fixing and creating an upgraded weather system update?
Great ideas such as here: Add more options for live-weather than only ON/OFF
And here: Realistic Dangerous Weather - Physics Simulation - #28 by HomieFFM
And here: Clouds are are just not realistic
also: Are Microburstphysics in MSFS 2020 implemented?
And many many more great threads about weather improvements/suggestions.
