I would say it all depends on the weather. Are you gonna snowshoe out to Dewey Point or somewhere up there, or staying low? If it is stormy, you may be fine until it clears off. Check weather before heading out, I would go with a 15F bag at least, as sleeping in the snow, on the cold snow, seems to require a little more. You may need a warmer bag, depending on if a cold front comes down from Canada or Alaska. You do have two pads right? Or at least a DAM pad? Have fun.
