I don't know if this idea has suggested before but I think it would be a cool feature. So basically just like radars that are already in game, you can build radar-like modules that will allow you to control weather of your town. I didn't figure out how it will work but what it will cost but lets say you put 10 diamonds and you want your town to be rainy, then it will be rainy for a limited time. Haven't got a design for it yet but i would want to see the idea in game.
