Texture [REQUEST]Stormy nighttime skybox?

Im looking for a stormy nighttime skybox (kinda like the gravel pit skybox dark, with some more clouds?)
Im making a rainy, stormy, swamp map and i need a dark grey stormy skybox for it! If you can do this, please let me know! I really need a skybox, its the last component needed for this map!
