Forecast Discussion: Phoenix saw the highest levels of ozone for the yesterday at the North Phoenix monitor. It seems this was local since most of the other parts of the Valley finished the day in the mid-Moderates. Moving forward, models have put ozone on a decreasing trend, falling back to the Good range due to the incoming frontal system. Since this is a wet system, cloud cover will begin to start increasing today with possible light rain showers tomorrow night. As for PM-10, wind speeds are expected to be a bit breezy ahead of this system. Therefore, the Valley could see isolated dust activity. But, after tomorrow, PM-10 activity should be lower due to the slight stabilization of the soils due to the expected precipitation. Check back tomorrow for more. Until then, have a good day! –P.Patel Last Update: Tuesday, March 21, 2017, 9:00 AM
