East Tennessee State University experts are forecasting a stunning fall color season across Appalachia.
Recent rainfall and cool nighttime temperatures are creating ideal conditions for the natural process that transforms summer’s green canopy into the brilliant reds, oranges and golds that draw visitors from around the world to the region’s mountains.
Weather outlook supports strong color
“The cooler pattern recently has likely been helpful and reduced summer-related stressors,” said Dr. Andrew Joyner, Tennessee’s official state climatologist and ETSU associate professor. “Climate Prediction Center maps show the next two to three weeks likely being a bit warmer than average, though not record-setting, and it appears we’ll have closer to average nighttime low temperatures.”
That combination is often favorable for fall leaf color development. Areas to the south, though, may see a different outcome.
“The Smokies and Chattanooga are more likely to be warmer during this period compared to Northeast Tennessee,” Joyner said. “That could lead to slightly earlier leaf drop with possible impacts on the vibrancy of colors in those locations. A system is forecasted to move through the area late next week, however, bringing some needed rainfall that should keep dry conditions at bay and maintain our chances of vibrant leaf color this fall.”
Elevation creates extended season
Appalachian geography creates a natural color calendar. Changes begin at the highest elevations and gradually work downward over several weeks, and this geographic diversity allows visitors to follow the progression of color across different elevations and habitats.
“The beauty of our Appalachian Mountains,” said ETSU Campus Arborist Travis Watson, “lies in its diversity.”
Planning for peak season
With optimal viewing approaching, now is the time to book autumn excursions. Most back roads and scenic viewing spots have reopened following summer maintenance, and mountain communities are preparing to welcome leaf peepers.
Watson recommends planning trips to the mountains for late September and early October to experience the splendor of the region’s autumn transformation.
