FORECAST: Ozone levels will be in the Low Moderate to Good range this week.  PM-10 levels will be in the Good range.



After the weekend storms, air quality should be good this week as high pressure returns with mostly clear skies, light winds and a gradual warm up. The only concern is a possible increase in ozone through Wednesday transported from California.
