For you S&WL players, you really didn't think I would forget you, right? Here's a weather generation table, just for you. (Not really. It can be used in pretty much any RPG.)
There's the Dropbox link. I'm probably going to send this one over to Tenkar's Tavern to try and get it put in Torchlight. So probably no Drivethru or RPGNOW.
Roll some dice, and slay some monsters!
