Forecast Discussion: Monday, an upper-level ridge of high pressure over northern California will reduce atmospheric mixing. In addition, mostly sunny skies and temperatures in the upper-90s will enhance ozone formation, and light onshore winds will limit pollutant dispersion. Therefore, ozone levels will be low-Unhealthy for Sensitive Groups. Tuesday is a Spare The Air Day in the Sacramento region. The upper-level ridge of high pressure will strengthen over northern California, limiting mixing and producing sunny skies and temperatures near 105F. These conditions will increase ground-level ozone production. Furthermore, light southwesterly winds will continue to limit dispersion. As a result, ozone levels will be Unhealthy for Sensitive Groups. Wednesday, sunny and hot conditions will continue to enhance ozone formation in the Sacramento region, and light winds will limit pollutant dispersion. These conditions, combined with pollutant carryover from Tuesday, will keep ozone levels Unhealthy for Sensitive Groups.
