Thursday through Saturday, as upper-level high pressure builds over northern California, mostly sunny skies and temperatures near 100F will enhance ozone formation in the Sacramento region. However, light to moderate onshore winds each afternoon will help to disperse pollutants. Therefore, ozone levels will be Unhealthy for Sensitive Groups on all three days.
