Forecast Discussion:

Yesterday's ozone levels were in the good AQI range. There will be more cloud cover in the short-term forecast, especially Sunday. The trend of ozone in the Good AQI range will continue through early next week. Lower ozone levels are expected Tuesday and later in the week due to increased cloud cover and showers/storms.

PM10 and PM2.5 were in the Good AQI range yesterday. The next couple of afternoons could have brief increases in concentrations because of storm development, but overall the rainfall in recent days will help limit how much is brought to the area. Early next week forecasts hint at showers and storms coming from the south in the afternoons, so hourly PM10 levels have been adjusted to show that potential. PM10 and PM2.5 are forecast to be in the Good AQI range through early next week.
