Might be able to still do some hiking in the North Cascades area. They got a little snow recently but may still be clear in parts. Mt Baker/Snoqualmie is also nice, but in Nov they require you have chains. Camping in the car won't be too comfortable since it will be chilly and probably wet. If rain doesn't bother you, head over to the Olympic Peninsula. Lots of great hiking and sights that won't have snow. Parts of the Peninsula are in the rain shadow which means you'll be drier.
