I've used an Ice Fishing tent to keep snow and ice off me and the gear. Sets up quickly and has tie-downs for windy conditions. They range in price starting around $100 and up to $600. The one I use was about $200, it keeps the snow away. The windows are only Velcroed in so the rain might come in around the seems. I'd imagine that the more expensive ones are built with better fabric and more waterproof.
