If I go tomorrow, I should leave as early as possible. We're leaving their house at nine or a bit before, and I'm not sure what traffic will be like.
They were trying to talk me into driving up later tonight, but I dunno. I don't know that it'll be much worse tomorrow than it will be tonight, though I think they were getting more snow than us.
Huh - well, I don't think more snow is expected overnight, but that's a hard call. On the one hand, I know you don't like driving at night. On the other hand, going tonight removes all time factors and related stress.
