Tuesday, sunny skies and temperatures in the mid-80s will aid ozone production in the Sacramento region. However, light to moderate onshore winds will develop during the afternoon, dispersing pollutants and leading to low-Moderate ozone levels. Wednesday, sunny skies and temperatures warming into the low-90s will enhance ozone development. In addition, onshore winds will weaken slightly, allowing pollutants to accumulate in the Sacramento region. Thus, ozone levels will increase to mid-Moderate. Thursday, as an upper-level ridge of high pressure begins to build over northern California, sunny skies and temperatures in the mid- to upper-90s will increase ozone formation. Furthermore, calm to light southwesterly winds will lead to pollutant build-up. As a result, ozone levels will be high-Moderate.
