Forecast Discussion: Thursday, an upper-level ridge of high pressure will build over the West Coast, reducing atmospheric mixing. However, light to moderate southeasterly winds will help to disperse pollutants in the Sacramento region, leading to Good particle levels. Friday, a cold front will move through northern California, enhancing mixing and generating moderate southeasterly winds. These conditions will aid pollutant dispersion. However, moisture associated with rain showers and mist will support particle formation, yielding low-Moderate particle levels. Saturday, high pressure building over northern California will generate light winds, reducing pollutant dispersion in the Sacramento region. Therefore, particle levels will be Moderate.
