The Cottonwoods have had a little over a foot in the last 48 hours and it is still snowing. Another foot to come later this week (hopefully).
Snowbird is opening the Tram on Thursday and chickadee and mid gad on Wednesday. I would venture a guess that both resorts open a ton more terrain for the holiday weekend. They have had 71" so far this season.
If you're going to come to CO, I'd suggest Steamboat or Crested Butte. They've been getting the goods lately. Summit County has largely been getting skunked, so unless you want to ride crowded as fuck scraped off hardpack, I'd pass. You'd basically be coming across the country to ride east coast type conditions.
