I just want to point out that third-party developers had already created amazing weather systems in P3D and FSX, featuring wing fade, localized thunderstorms, and even tornadoes. Just check out Active Sky Next and Rex SkyForce. The problem is that the developers haven’t made a serious effort to advance the weather engine beyond its original capabilities. Their focus has been on growing the user base and enhancing the “static world.” If they simply developed an SDK and allowed weather experts to build a system alongside the default one, I’m confident the community would have shown strong support for it.
