Climate data shows that average hi/lo temps for June:
Gatlinburg - 86º/58º (1,462' in elevation)
Clingman's Dome - 63º/49º (6,643' in elevation)
The bulk of the AT is around 5,000' in elevation.
Actual temperatures will likely be +/-10º from these numbers (with extreme weather events extending that range beyond +/-15º).
