Stuart, congrats on the purchase. I have often went back and forth on whether I should have purchased my 300mm f/4 IS or that lens. Kind of wish I would have went your route. Having said that, there are tons of photo opportunities during snow. Just put a sandwich bag over your lens to protect it from the elements (make sure all of the crumbs are out) and go have some fun. This was all 2 minutes from my house.
