Air Quality Forecast and Weather Discussion
Tuesday through Thursday, generally light winds throughout most of each day will reduce pollutant dispersion in the Sacramento region, allowing pollutants to accumulate. In addition, overnight temperature inversions will trap pollutants at ground level. However, light northwesterly winds will develop each afternoon, aiding dispersion. In addition, pollutant carryover from day to day will be low. As a result, particle levels will be Good on Tuesday and low- to mid-Moderate on Wednesday and Thursday.
