Climate varies considerably: Destin's humid subtropical gives way to a continental climate in St. Louis. Spring and fall offer mild temperatures, but summer can bring thunderstorms from the Gulf, especially in Alabama. Winter travel may encounter ice north of Nashville. For aesthetics, the stretch between Birmingham and Nashville is best in early October when the leaves turn.
