So uh...this happened. http://i.imgur.com/zs3lH0S.jpg I think it might have something to do with frostfall but I'm not sure. I also verified the integrity of my game cache but nothing happened. It doesn't happen everywhere but it started when frostfall said it began to snow and when I went into Windhelm.
Edit: Turns out it was a mod called "ENB Snow FX". I forgot I had it when I deleted my enb and after I deactivated it everything was fixed. Thanks for the help guys.
Edit 2: Can people not read this post? It's fixed, I don't need any more help. Stahp.
