We've had an extra hot summer in the southwest, too. Here in southern NM we have been hotter and more humid than we have seen in years. We routinely go 24 hours without the temps going under 80 with humidity running 40% - 50% (not much, I know, but a lot for us). Weird because 4 hours north where my parents live (still in NM) they are having one of the coldest summers on record. Weather is weird.
