As for temperatures, the average temperature difference between the mountains (Newfound Gap around 5,000 feet MSL or 1,524 m) and the valleys (Park Headquarters around 1,600 feet MSL or 488 m) in the Great Smoky Mountains National Park is between 10 and with highs and between 3 and with lows. The difference between high temperatures is similar to the moist adiabatic lapse rate (3.3 degrees Fahrenheit per 1,000 ft), while the smaller difference between low temperatures is the result of frequent temperature inversions developing in the morning, especially during autumn.
