I scratch my head when I read these reports stating something to the effect of "I was gonna go but it rained."
Folks, for the most part, your best days on Table Rock will be the nastiest. By no means should you fish in a lightning storm --- get under a dock or off the water fast --- but don't be afraid of a little rain. Good rainsuits exist at all price points these days.
Anytime the water temp starts trending downward into the low 80s as fall approaches, there will be a shallow spinnerbait bite somewhere. I usually start looking around main-lake points, throwing into a variety of depths until I locate the fish. Generally, I use a medium-fast retrieve and keep the bait in the top 5 feet of the water column. If the fish are around, they'll come up and get it. Dock corners get very good in the fall, too. You'll catch spots, including some big ol' footballs, on the outside corners and LM on the inside corners.
Good luck out there. Looks like we may have some early fall fishing this year.
