Air Quality Forecast and Weather Discussion
Friday, a cold front will move across the Sacramento region, increasing vertical mixing. However, higher humidity associated with rain showers, fog, and mist will enhance particle production, and light easterly to southeasterly winds late in the day will transport pollutants into the region. Therefore, particle levels will be low-Moderate. Saturday, an upper-level ridge of high pressure will approach northern California, limiting vertical mixing. At the surface, light winds will inhibit dispersion, while morning fog will enhance particle production. Thus, particle levels will be Moderate. Sunday, light southeasterly winds early in the day will gradually transport pollutants into the Sacramento region. Additionally, morning fog will enhance particle production. However, vertical mixing will increase throughout the day as another cold front passes over the region. As a result, particle levels will be low-Moderate.
