Air Quality Forecast and Weather Discussion
Wednesday and Thursday, as an upper-level trough of low pressure departs the Sacramento Valley, vertical mixing will decrease, allowing pollutants to accumulate. In addition, light to moderate southeasterly winds each day will transport regional pollutants into the area, and morning fog and mist will enhance particle production. These conditions will lead to Moderate particle levels on both days. Friday, lingering fog and mist during the morning hours will continue supporting particle formation. However, an approaching cold front will shift winds from southeasterly to southwesterly, aiding dispersion. Thus, particle levels will remain Moderate.
