Air Quality Forecast and Weather Discussion
Thursday, upper-level high pressure moving over the Sacramento Valley will limit vertical mixing. At the surface, light southerly to southeasterly winds will hinder pollutant dispersion and gradually transport pollutants into the region. Therefore, particle levels will be Moderate. Friday, a cold front will move into the Sacramento region, increasing mixing and dispersion. However, higher humidity associated with rain showers, fog, and mist will enhance particle production, leading to low-Moderate particle levels. Saturday, light and variable morning winds will inhibit dispersion, while morning fog will enhance particle production. Therefore, despite northwesterly afternoon winds aiding dispersion, particle levels will be Moderate.
