HIFI TECH - ACTIVE SKY FS MSFS
It may not be exactly transformative for MSFS weather, but in my eyes, it depicts a greater and more realistic assortment of cloud formations, better winds, better turbulence effects and realistic thunderstorms. More importantly, for those critics who thought this was a 'cash grab', the developer has already pushed out a major update and has another lined up for imminent release. The support will continue, and this add-on will continue to improve. IMO, for the price, I have found it adds to my sim experience, and I'll fly with it all the time.
