PHOENIX -- Deep monsoon moisture will remain over Arizona for the next several days, prompting the threat of an isolated shower or storm in the Valley each afternoon and evening.

Saturday evening, the threat for rain or blowing dust will continue until 11 p.m. across the Valley. Otherwise, look for mostly to partly cloudy skies and a low of 86 degrees in Phoenix.

The best threat for showers and storms is in the central and eastern mountains of Arizona. Doppler radar showed pockets of heavy rain and lightning around the Grand Canyon, the Flagstaff area and Prescott this afternoon. Again, this convection should taper off by midnight or so and return late Sunday morning or early Sunday afternoon.

Most of the Valley will see mostly sunny to partly sunny skies Sunday. Phoenix should top out at 107. A slight threat of showers or storms returns to the forecast Sunday evening.

Monday’s weather will be pretty comparable to Sunday’s.

On Tuesday, an area of low pressure will retrograde from the east and a warm, moist flow from the south will amplify. This will increase our threat for monsoon activity. For now, the Valley has a 30 percent chance of showers and storms both Tuesday and Wednesday with highs around 100.
