Weather Conditions:
Wednesday and Thursday, mostly sunny skies and temperatures in the upper-80s will enhance ozone production in the Sacramento region. However, light to moderate onshore winds will aid pollutant dispersion. As a result, ozone levels will be high-Moderate on both days. Friday, a weak upper-level trough of low pressure moving through northern California will enhance mixing in the atmosphere. In addition, light to moderate onshore winds will continue to disperse pollutants. Therefore, ozone levels will be Moderate.
