Foster Falls Moderates After Rain?

I'm in Chattanooga through Sunday morning, hoping to get out sport climbing on Saturday. I'm not familiar with the area, so I'm not sure what will stay dry or likely dry out. Can anyone with local knowledge help me out? I'm visiting a friend who will do better on easy routes (8s, 9s), but I'm hoping to be on 10s or easy 11s towards the end of the day.

Are there any good Foster alternatives? I'm entertaining the idea of bouldering, but since I'm recovering from a knee injury, I'm not sure it's a good idea.

Thanks!

Oddly...whatever it is doing in Chattanooga proper is not always the best indicator of what's happening in other valleys (Sequatchie, Little River Canyon, etc). I've woken up to rain at my house and driven into Sequatchie to find sun and wind. Your best bet is to just drive out there and see for yourself. Exposed areas will dry fastest. Bouldering areas will dry out last. Lizard Wall in the Canyon will be dry if the dew point is low...it doesn't get wet in the rain.
