TUCSON, Ariz. (13 News) – After another triple-digit day, it finally looks like we’ll enter a prolonged sub-100-degree stretch, with temps possibly only getting to the 80s some days! A big reason for that is widespread rainfall returning to the region this weekend due to a tropical moisture surge. Scattered rainfall will likely return on Saturday through Monday, with Sunday looking to have the most widespread action. Temps stay cool even as we dry out next week.
