Air Quality Forecast and Weather Discussion
Friday and Saturday, an upper-level ridge of high pressure over northern California will decrease vertical mixing in the lower levels of the atmosphere. In addition, light and variable winds throughout most of each day will reduce pollutant dispersion, and morning fog will enhance particle formation. Therefore, particle levels will be Moderate on both days. Sunday, as a cold front moves through northern California and departs to the east, moderate and gusty southerly winds will disperse pollutants in the Sacramento region, leading to low-Moderate particle levels.
