As far as I know, we haven’t made any changes to the weather code (these typically come in a Sim Update, and we would announce the change in the release notes), so my suspicion is any recent improvements you are noticing is indeed a “false positive”. I appreciate that some of you are pleased with the current implementation of Live Weather, though, and I’ll pass on your feedback to the devs. I’ll also confirm if there were any recent server-side changes to the Weather system that weren’t included as part of a client-side update.
Thanks,
MSFS Team
