Forecast Discussion: Saturday, a cold front will move through the Sacramento region, producing widespread rain showers and moderate southerly winds. These weather conditions will effectively disperse pollutants, yielding Good particle levels. Sunday, moderate northwesterly winds behind the departing cold front will keep pollutants well dispersed, keeping particle levels Good. Monday, an upper-level ridge of high pressure will strengthen over northern California, reducing mixing in the atmosphere. In addition, light winds at the surface will inhibit pollutant dispersion. As a result, particle levels will be Moderate.
