Arizona, New Mexico are desirable if you're looking for dry / warmer temps. Prescott, Az is great as is Las Cruces NM. Just be mindful of altitude and you'll be ok. I currently live south of Tucson at 3000 ft. The summers are hot but even then you have nice mornings and decent late afternoons. After summer passes the desert is sublime the other 3 seasons. I left Houston heat and humidity years ago and haven't looked back.
