Good weather at the end of November might be a real possibility this year.
I don't know what effect climate change will have on leaves and stuff. I know length of daylight is also important to plants, and so far humans haven't figured out a way to mess with that.
As of today, the trees here in southern Michigan still have some good autumn color, but they're starting to look raggedy. We have rainy/windy weather in the forecast that will probably take down most of the leaves pretty soon.
