100% agreed.
Plenty of talk of a quite warm November on the Mid-Atlantic, which, assuming the source region in Canada doesn't torch, could be a good thing in setting up a possible colder period into December-January, as you said.
In my opinion, November is a great torch month. It can be plenty warm enough for t-shirts and really pleasant days, but it won't get hot, and those warm days are almost always dry. Any cold days are just wasted, so better it be mild!
