We were just on WNC side near Cherokee 10/17 to 10/22.
Colors are late this year due to warmer fall and lots of rain.
On the road across Newfound Gap, pretty much all the leaves are gone above 5K feet due to high winds 2 weeks ago. At 3-4K feet up and down the mountain, the colors are great. The valleys down around 2.5K feet are still mostly green. Grass is still green everywhere - they had not had a frost yet.
The Blue Ridge Parkway around Cherokee was by far the most color we saw.
I suspect you will nail it perfectly the weekend of 11/1. There's always color somewhere during this season, you just have to find the right elevation.
