Yeah, I know and I was hoping! We made numerous requests in the Hourglass chronometer threat for weather control. It would be amazing if ZOS came out with one. Some people like the rain, but for me bright sunny mid-days all the way.
That's a nice idea and maybe something they can implement along the way for housing. I would really like for some houses like Cyrodiilic Jungle House, that have an overcast sky, to be more sunlit and cheery, for example. That concept art is really pretty too, by the way.
I too would like a weather control. I recently built a gate house in the Enchanted Snow Globe (partly to obscure the crappy wooden dock). It's surprising how cold the interior of the building feels with snow flakes blowing through the walls.
