Update: I did a quick check of the turkey at dinner time yesterday. It was only soft for about 1/2" on the outside. I took it out of the fridge, and put it into cold water overnight. This morning, it seems much more thawed, maybe 1-2", so I put it back into the fridge. I think it'll be fine for Monday, when I take it out and spatchcock it and dry brine for the day.
