I think it'd be pretty cool to add weather systems to the game.
What I imagine is:
There'd be a numerical value associated with the intensity of the weather in the region (thunderstorms, snow, etc) and as the weather intensity increases, the efficiency and speed of your nearby units decreases.
You'd be able to see weather patterns moving around on the map, and you'd need to be a little bit more thoughtful as to what path your units take at any given time.
