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