I'd add NM and southern CO to your list. Then just wait as long as possible to book.
There will be lots of trip reports after Thanksgiving and you'll be able to get a much better idea of who is skiing well.
Skier traffic has a huge effect on surface conditions early season.
The skiing was really good this weekend in Aspen. But we had 2500 skiers Saturday, which is a big day for Aspen and only 15-20% of the terrain.
Add another 1500 on Sunday, with warm temps and it showed by the end of the day.
Luckily, it snowed 7" and another storms coming Friday.
