Will my turkey cook in time?

I just bought a 21 lb turkey at Wal-mart and want to know if I leave it out will it be thawed enough to cook it tomorrow? I don't know if it was totally frozen or not but it's still out in the trunk of the car and it is 10:30 here in Northwest Arkansas and I bought it about 5 o'clock this evening. We plan on eating it about 2 or 3 tomorrow.
