Forecast Discussion:

Ozone levels managed to reach into the Moderate category again yesterday, while PM10 and PM2.5 stayed in the Good range. Looking ahead, we expect ozone to again be relatively high today with light westerly winds. Over the remainder of the forecast period, we are forecasting ozone levels to trend down with improving ventilation from an approaching trough. By the start of next week, it is possible ozone levels will drop into the Good AQI category.

As for PM10 and PM2.5, we don't expect any winds strong enough to cause significant dust issues. Therefore, particulate levels are forecast to stay in the Good category throughout the forecast period.
