Air Quality Forecast and Weather Discussion
Saturday and Sunday, as surface high pressure develops north of the region and moves toward the Great Basin, northwesterly winds will aid mixing and dispersion each day. In addition, pollutant carryover in the Sacramento region will be low from day to day. As a result, particle levels will be Good on both days. Monday, a strong overnight inversion and calm morning winds will allow pollutants to accumulate in the Sacramento region. However, mixing and dispersion will improve in the afternoon as southerly winds develop ahead of an approaching low pressure system. These conditions will lead to high-Good particle levels.
