I'm on the wrong side of the state but we do have a few folks out that way. Typically we don't have a lot of rain, but as in anywhere that can change. As for stuff to see Asheville is nice with lots to do. http://www.blueridgeparkway.org/
Here's the link for the parkway. You can keep up on weather and any possible closings. Not sure if they fixed that one part yet. I'm sure someone might let you know if they can be a tour guide for ya. Weather can be changeable up there though. Just make sure to bring warm clothes and you should be fine. Here's the tourism site in case there's any things you would be interested in. http://www.visitnc.com
Oh and if you ever make it to this side of the state I can help you out on places to go as tour guide.
Enjoy your trip.
