Yay and for OBGE will it be possible to have different water types/conditions so in stormy weather I can have stormy water? Is it possible to have large waves? If yes how do you make them? If you need any help at all with this kind of thing I am more than willing to help and will help to the best of my ability (which isn't that high yet) but hey I'm a fast learner

I've actually got this in my to-do list of things for Enhanced Seasons, a WIP I'm making. I'm thinking of having regional water differences and weather water differences too. But I've put shaders for ScreenEffects-like effects before that, and I'm stuck on the final shader effect.
I think it would also be cool with a future OBGE to create wet looking surfaces when it rains. I bet that would be possible later on.
Yeah, I fell in love with Crysis' rain shader. It shouldn't be that difficult to do, though I bet you you need depth buffer or something for it to work properly.
This would also mean awesome interior weather effects with All Natural - just apply the shader to the interior window panes.

I always wondered whether it was possible to have the sun melt just a bit of snow in bruma and when it snows in other places to actually add snow to the ground...

Snow is a lot harder than rain to get looking right... Even Crysis' snow/ice shader looks a bit rubbish on larger objects.
