You're going to get at least some snow on that route. I'm in the Sacramento area now, and Donner Pass (the area around the NV/CA border) will definitely have had some snow by then. In fact, it's snowed up there already this year, though it quickly melted. As someone mentioned, it's often a chains-required section of the interstate, and it's even been known to close for a number of hours due to snow. That said, they do a great job of clearing it as fast as weather allows. I don't have personal experience with most of the rest of the route, but I do wonder if taking the more southern route you have on your map rather than right along the Great Lakes might make a difference in snow amounts.
