We were there 11-9 thru 11-17 in 2001. It was around 80 + degrees every day and maybe high 60's in evening. I know we usually grabbed a light jacket for evenings, but we stayed in shorts. The weather was beautiful. We have also been there the week after Thanksgiving (nov/dec week) and it was in the 60-70's.
Everything I read about November when I was researching last year said it was typically a pretty mild month. But can be a little unpredictible. We have found it to be the best.
I would just wait until 15 days before you leave and check accuweather to get an idea of what its going to be like.
