It is supposed to rain again tonight. So no, a weekend trip is not worth it any where in the south. Sunday will be the best day. The Bald is a great option because the cliff's do dry fast, but the boulders do not. Better off sticking to the gym, especially with that far of a drive.
The Bald is the driest place around. You will be good there either day. South Side of LG runs a lot. It normally dries out late morning earlier afternoon. Sun Wall dries faster. The Nose being the fastest. 475B is still closed. This adds 30 more minutes to the hike from the fish hatchery. I would stick to the Bald, as LG is much more of a chance.
