It's not 'normally' so warm in early November (in the mid-70° F range); we often have what we call an Indian summer in September, and sometimes into October, but in a warming climate, I guess temperatures are more variable than ever (at least some models predict this!)
But, fall color this year is absolutely amazing -- it's late, but the vivid yellows, reds, and oranges have clear notes, and the peak (this week) is more vibrant than I've ever seen it here before (we've lived here almost 15 years).
