My turkey is almost done and we need to postpone the dinner until tomorrow due to an emergency. Any suggestions?

I'd keep it cool tonight, tented with foil. The next day carve it, put it on an oven-safe platter with gravy, and reheat in a low temp oven. Here are more tips from Ina: https://food52.com/blog/11742-ina-garten-s-make-ahead-thanksgiving-advice

If you have the time, finish off that turkey. It'll keep till tomorrow.
