Forecast Discussion: Tuesday through Thursday, an upper-level trough of low pressure will move into northern California, enhancing vertical mixing in the atmosphere. In addition, light to moderate onshore winds will effectively disperse pollutants in the Sacramento area. However, these winds will transport pollutants into the foothills. In addition, mostly sunny skies will support ozone formation, resulting in Moderate ozone levels on all three days.
