In addition to the single-wall tents you might want to consider the Big Agnes Fly Creek. I have one and it has worked well for me in light snow, high winds and in heavy, windy thunderstorm rain. It is sorta free-standing without the fly, small and light; 2 lb with stakes for mine. It has been reviewed by a number of people, just Google reviews for this tent. Most, but not all, reviewers liked the Fly Creek.
