Is there any way to turn off the near-constant snow?

The snow is a seasonal thing controlled server-side, but you can make the snow less dense or turn it off altogether by going to Options (or hit \), select Advanced, and use the 'Weather Detail' slider on the left. All the way down will turn it off completely.

EDIT: Also the weather stuff was likely on a calendar schedule during live, but I think the seasonal stuff is changed manually in the server emulator. Not sure, only Rajko can speak to that.
