Here is my prediction of what will be open:

In regards to Planet Snoopy: After some re-evaluating & remembering this is a family-geared event, there would need to be some rides for younger children. I could see some of the rides being untouched open: Charlie Brown Wind Up, Balloon Race, Snoopy vs, Red Baron & Snoopy's Junction (what's Christmas without a Christmas themed train?). Also Flying Ace Aerial Chase could be open for the younger crowd. The rest of Planet Snoopy could be walled off for construction during Winterfest, with them likely focusing on the ride removal and installation of Beagle Scout Acres.
I pretty much see Thrill Zone and Crossroads completely closed. This would still leave the availability to circle the park. I could see a nice decorative walk-through along the path under Nighthawk. Intimidator & Nighthawk could possibly be running, but pretty sure Windseeker would be closed (as well as Skytower). Not sure about Ripord. I've seen people in Orlando ride Skycoasters in cold weather, but don't know if Carowinds would bother with it.
From there County Fair should all be open, along with possibly Carolina Goldrusher, Ricochet and Scrambler. With the construction in Carolina Showplace, I don't see Vortex or Slingshot open. Carolina Cyclone I don't see worth opening either and easy to block off along with Thrill Zone.
As far as indoor show areas, there would be Carowinds Theater and Harmony Hall. Then of course there's the plaza stage and other locations for entertainment.
Anyway, this is just what I predict it would be. As much as many would love the whole park to be open, there just isn't any need for it, especially since it's still a "new" venture for Cedar Fair at this park. More could be open or perhaps I'm being overly generous. As far as Fury 325, I think it's just it's location as why I don't think it would open since that area is just easy to block off, besides the unpredictable forecast. I can see a nightmare if it's included, but closed for weather. Intimidator I don't think would be as bad if it had to close.
