Unhealthy for Sensitive Groups
Forecast Discussion: Wednesday, light onshore winds will limit pollutant dispersion in the Sacramento region. Furthermore, sunny skies and temperatures in the mid-90s will support ozone formation. These conditions will cause ozone levels to be Unhealthy for Sensitive Groups. Thursday is a Spare The Air day in the Sacramento region. An upper-level ridge of high pressure will begin to build over northern California, reducing atmospheric mixing and trapping pollutants near the ground. Furthermore, temperatures in the upper-90s will enhance ozone formation, and light southwesterly winds will limit dispersion. These conditions will keep ozone levels Unhealthy for Sensitive Groups. Friday, onshore winds will strengthen slightly, increasing pollutant dispersion. However, sunny and hot conditions will continue to enhance ozone production. Therefore, ozone levels will remain Unhealthy for Sensitive Groups.
