Please don't cook it until the temperature is that high--it will be dried out. The thigh temperature of an unstuffed bird should be 160ºF when you take it out; then let it sit on the carving board for 30-45 minutes (covered with foil, and maybe even a towel on top of that, if it is a smaller bird), during which time the interior will continue to rise in temperature.

Since you still have a full day before you roast it, you can do a dry brine to make the turkey more juicy.
