If your are thinking about wind, a decal that adds a little bit of "pasted on" snow that has blown onto on walls could work well.
Of course everything you have so far looks great anyways.
/Edit:
Do the players and zombies walk on top of the snow or slightly under it? Since real people sink into snow, it would be interesting if the players walked slower in some areas and if they walked over a surface just a few inches deeper then the snow. This of course would be tough to do, and the lack of foot prints might make the zombies look un-natural.
