Forecast Discussion:

Overall, a low-grade monsoon pattern will persist throughout the weekend and into early next week. Therefore, we can't rule out winds from distant thunderstorms moving into Pinal County in the evenings/nights and resulting in dust. The recent rain around central Arizona should help to reduce dust in near-future rounds of dust, but we can't completely rule out the possibility of more dust. Perhaps an isolated storm or two will be able to develop over the area, too.

Next, ozone levels are expected to be elevated throughout the period, unless storm-related clouds are able to move over the area during the day. Ozone is forecast in the Moderate AQI category each day.

Check back on Monday morning for the next update.
