Wednesday, sunny skies and temperatures warming into the low-90s will support ozone development. In addition, a light delta breeze in the afternoon will allow pollutants to accumulate in the Sacramento region. Thus, ozone levels will be mid-Moderate. Thursday, sunny skies and temperatures in the mid-90s will increase ozone formation. Furthermore, calm to light onshore winds will limit dispersion, and a morning inversion will trap ozone precursors near the ground. As a result, ozone levels will be high-Moderate. Friday, onshore winds will strengthen, aiding dispersion. However, abundant sunshine and temperatures in the low-90s will be sufficient for ozone formation. Therefore, ozone levels will be mid-Moderate.
