When I left near Grandfather Mtn. Sunday (9-13), it was 46 degrees at 8:30 am. I got a little uncomfortable, but when I returned around 1 pm, it was in the mid 70's. It has been warmer the rest of this week, but it won't be long til frost at 3600 ft. and up. Be prepared, fall is upon us, the temps will get lower from here on out.
