Air Quality Forecast and Weather Discussion
Saturday and Sunday, periods of moderate onshore winds will aid pollutant dispersion. However, mostly sunny skies and very warm temperatures will enhance ozone production in the Sacramento region. In addition, smoke from the Ferguson Fire will continue to impact the region. These conditions will cause ozone levels to be Unhealthy for Sensitive Groups on both days. Monday, lighter daytime winds will reduce pollutant dispersion, and sunny skies and temperatures near 100F will enhance ozone formation. In addition, lingering smoke from the Ferguson Fire will continue to impact the region. Therefore, despite onshore winds increasing in the evening and aiding pollutant dispersion, ozone levels will remain Unhealthy for Sensitive Groups.
