An upper-level trough will move across Arizona from northwest to southeast tomorrow then cut off from the jet stream and retrograde slowly back over central Arizona on Wednesday and Thursday. As a result expect variable cloudiness and breezes the next few days, with a chance of showers or thunderstorms Wednesday afternoon – Friday evening.
Temperatures will remain generally above normal for at least the next week.
