Forecast Discussion: Tuesday, northwesterly winds will diminish in the Sacramento region, reducing pollutant dispersion. Furthermore, as an upper-level ridge of high pressure builds over California, sunny skies and very warm temperatures will enhance ozone formation. In addition, smoke from the Lowell Fire in Nevada County will impact sites in the the foothills and the eastern portion of the valley, increasing particle levels and enhancing ozone formation. These conditions will lead to high-Moderate ozone levels. Wednesday is a Spare The Air Day in the Sacramento region. As the upper-level ridge persists, sunny skies and temperatures in the triple digits will continue to support ozone production. Furthermore, light onshore winds will inhibit pollutant dispersion. These conditions, combined with lingering smoke from the Lowell Fire, will lead to Unhealthy for Sensitive Groups ozone levels. Thursday, mostly sunny skies and very warm temperatures will aid ozone formation, and light southwesterly winds will inhibit pollutant dispersion in the Sacramento region. As a result, ozone levels will remain Unhealthy for Sensitive Groups.
