Forecast Discussion: Saturday, a weak upper-level ridge of high pressure over California will generate sunny skies and temperatures in the upper-80s, enhancing ozone formation in the Sacramento region. Therefore, despite light to moderate onshore winds dispersing pollutants, ozone levels will be Moderate. Sunday, an upper-level trough of low pressure will move into northern California, enhancing atmospheric mixing and strengthening the onshore flow. These conditions will disperse pollutants. In addition, slightly cooler temperatures will reduce ozone formation. As a result, ozone levels will be low-Moderate. Monday, the upper-level trough of low pressure over northern California will continue to enhance vertical mixing in the atmosphere and strengthen onshore flow, helping to disperse pollutants and lowering ozone levels to Good.
