Forecast Discussion: Wednesday and Thursday, a weak upper-level ridge of high pressure will begin to strengthen over northern California, reducing vertical mixing in the atmosphere. Furthermore, sunny, warm conditions will support the formation of ozone in the Sacramento region. Therefore, despite moderate onshore winds helping to disperse pollutants each day, ozone levels will remain Moderate on both days. Friday, an upper-level trough of low pressure will enhance vertical mixing over northern California. In addition, moderate onshore winds will help to disperse pollutants in the Sacramento region. Therefore, despite sunny skies and warm temperatures aiding ozone formation, ozone levels will be Good.
