Air Quality Forecast and Weather Discussion
Thursday, moderate south-southeasterly winds will aid dispersion. However, the winds will also transport regional pollutants into the Sacramento Valley, leading to low-Moderate particle levels. Friday, a weak temperature inversion will limit dispersion early, while areas of morning fog promote particle formation. In addition, light southerly winds will limit dispersion throughout the day, resulting in high-Good to low-Moderate particle levels. Saturday, a strong trough of low pressure aloft and gusty southeasterly winds will enhance atmospheric mixing. In addition, periods of rain will aid dispersion. Therefore, particle levels will be Good.
