Forecast Discussion: High pressure will slowly move over the forecast area this weekend. Both ozone and particle concentrations will rise gradually through Monday. On Saturday, good vertical mixing and low regional pollutant concentrations will keep air quality in the upper end of the Good range. Extended Outlook: Light winds and steadily rising temperature and humidity will push air quality into the Moderate range on Sunday. Highest concentration will occur Monday as weekday precursor emissions combine with full sun and light wind to bring Moderate air quality. -Ryan
