How about the Front Range cities of Colorado?
On another forum in a commuting thread, All winter long CO people are always lording over the rest of us that when it snows, it lasts a day then it's 50 or 60 again. I've been there in the summer and its dry like the southwest, but cooler and more tolerable. Coming from an East Coast muggy summer, the 90°F days were actually quite refreshing--that "dry heat" and all.
You're in IT, right? Lots of IT in the area too.
