Jadaharabi said
It has dropped to 70 degrees from 85. They said it rained but I don't know where. Maybe at 30,000 ft.
All I know is it sure feels cooler.

but is it cooler because it's "damp" with lower temp or just cooler temp with less humidity? (yes,I'm being a SA so please don't take it wrong,it's just the same discussion my wife and I have...)
