Ok you got your solutions, I just want to clarify: as Ame and the other devs have written in a great number of threads, and in the changelog of E16, in this new episode weather works by cycles. Each cycle is predefined and lasts 5 days, with weather slightly changing every 8 hours, also depending on your location. So if for example you have really Sunny days, this won't bè likely to change until the cycle is finished. With this being said, It has been reported that this system is broken, and seems like it's impossibile to get windy weather.
