Saturday and Sunday, temperature inversions will confine pollutants near the surface each morning and evening in the Sacramento Valley. In addition, light and variable winds will hinder dispersion each day. As a result, particle levels will be mid-Moderate on both days. Monday, a morning temperature inversion and light winds will limit mixing and dispersion early in the day. However, an approaching trough of low pressure will aid mixing during the afternoon and evening, while light onshore winds promote dispersion. These conditions will allow particle levels to improve to low-Moderate.
