I think all AH needs to do with the cloud is fluff it out a little bit more. 
So you can fly in and out and make it opaque but don't cover the whole arena with a sheet of cloud.   As it is now the clouds gradually move across the terrain,   having a few pockets of cloud would be cool but if there is too much it can get annoying.
A good example of this is on A32 ?  Baltic,  the base on the far east side sitting in Finland.
