Forecast Discussion: Monday, as surface high pressure builds over the Pacific Northwest, light to moderate northwesterly winds will develop in the Sacramento region, dispersing pollutants. However, sunny skies and temperatures in the mid-90s will aid ozone formation, leading to Moderate ozone levels. Tuesday, northwesterly winds will diminish, 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 may impact sites in the foothills, increasing particle levels and enhancing ozone formation. These conditions will lead to high-Moderate ozone levels. Wednesday, sunny skies and temperatures in the triple digits will continue to support ozone production in the Sacramento region, and 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.
