 Tonight, with a decent chance of a monsoon storm. Today, Sunday, we'll have the best chances, especially later this evening. We expect a cluster of thunderstorms to develop near the Tucson area, and that's going to be moving northwestward into south central Arizona by this evening. Tucson police are reporting a 68-year-old woman was killed in a car crash last night. Candace Ann Zenner was killed and a 35-year-old woman.
