Forecast Discussion: Tuesday and Wednesday are Spare the Air Days in the Sacramento region. Calm to light onshore winds will inhibit pollutant dispersion, and temperatures near 105F will enhance ozone formation. In addition, an upper-level ridge of high pressure will limit vertical mixing, and smoke transported into the area from the Soberanes Fire will aid ozone production. These conditions will lead to Unhealthy ozone levels on Tuesday and Unhealthy for Sensitive Groups ozone levels on Wednesday. Thursday, light to moderate southwesterly winds, especially during the afternoon and evening, will aid pollutant dispersion. However, temperatures above 100F will continue to enhance ozone formation, and lingering smoke from the Soberanes Fire will enhance ozone formation. These conditions, combined with pollutant carryover from previous days, will keep ozone levels Unhealthy for Sensitive Groups.
