The driest weather of the year in the southeast U.S. happens in late September through mid-November. A high-pressure system usually moderates the weather in the fall. Unless a tropical storm moves this way, like when I hiked the Benton MacKaye Trail, the area doesn't usually see much rainfall.
That's been true so far on this hike. I haven't seen any rain. The few clouds that formed from time to time were scattered and light. To be truthful, though, I haven't had many chances to see the sky lately. Until Polecat and I climbed to the top of Rabun Bald yesterday, we had been under a canopy of trees for most of this hike.
