Storm clouds are building north and farther south of Phoenix on the first full day of fall, and that means the Valley may get a little weather instead of the usual dry shrug. Models are split on timing, but a pop-up shower or two are possible tonight across the northern portions of the Valley.
The bigger wrinkle is that those storms could kick out multiple outflow boundaries, which is weather-speak for the kind of setup that can shove dust around and make the evening more interesting than anyone asked for. The forecast also leaves room for blowing dust across the Phoenix area this week.
For Valley residents, the practical takeaway is simple: keep an eye on the sky and the forecast, because the atmosphere appears to be in one of its moods. Not dramatic enough to cancel the season, just dramatic enough to remind everyone that Arizona likes to keep a weather app installed for a reason.
Fall has arrived, and apparently so has the part where the desert tries to make a point.
