Tucson, Arizona – Dangerous heat continues to grip southern Arizona this week, with temperatures expected to hit a brutal 114°F on Thursday and remain in the triple digits through Friday evening. An Extreme Heat Warning remains in effect until 8 p.m. MST Friday for much of southeast Arizona, including Pima, Cochise, and Pinal counties.
