Weather Revamp, more predictable and realistic Storms and Cloud formations.

I have been very fascinated by weather lately, here in south Arizona we have the monsoon, Arizona's monsoon season begins in June and continues through September. With it comes higher humidity, which can lead to thunderstorms, heavy rain, lightning, hail, high winds, flash flooding, dust storms and extreme heat. but you know this makes me think how cool a weather update could really be, instead of just having the same old clouds, you can have it be more realistic, with different shapes forming at spots moving across the map and changing, there could be tornados, but if they are added, they would have to be more balanced or something, as you cant just have some random storm wipe away your awesome build just because. but making the weather a bit more predictable and to instead of being the whole map, having different storms forming at different parts all over the map, the only problem I see with this is performance, but, there is almost always a way around that so yeah. I kinda want to do some more research on weather and seeing how it works.
