I was holding off on a decision since the weather seemed questionable. Now I'm leaning heavily towards heading north some other weekend. I will ride in some cold, I will ride in some rain; but I've ridden a few times in cold rain or snow and that's just not much fun at all... It does make for an adventure though.
When in doubt, gas it. It will either fix the problem, or at the very least end the suspense.
