Winters in Florida can be relatively dry as most significant rain is supposed to be over by onset of Fall. However, as a tropical, coastal state, Florida is always subject to the possibility of rains, so there is no way to guarantee there wont be rain during Thanksgiving.

Weatherspark's averages page for Orlando indicates that in late November there is typically a ~30% chance of rain on any given day. For Panama City up in the panhandle, the chance is lower at 20% but I would still expect rain at some point if you're there for a week.
