Forecast Discussion:

Air quality remained in the Good AQI range over the weekend, and no major issues are expected this week either. Calm, sunny conditions may allow ozone to peak into the Moderate range this week, but we don't expect any significant buildup of ozone. As for PM10, there may be some periodic gusty winds from nearby thunderstorms during the afternoons later in the week, but soils in the region should be stable enough to prevent any blowing dust. PM10 is forecast to remain in the Good AQI range through the forecast period.
