Thursday's ozone readings reached the lower Moderate AQI range.
For today, we expect ozone values to hold in the upper Good AQI range, then trend somewhat lower for the weekend through Monday with improved ventilation as a potent upper-level low develops and dives south, through northern Arizona into southern portions of the state this weekend.
Gusty winds develop again on Saturday. No significant precipitation is expected from this weather system.
