Air Quality Forecast and Weather Discussion
Tuesday, light winds will inhibit pollutant dispersion, and an overnight temperature inversion will trap pollutants near the ground. However, pollutant carryover from Monday will be low. As a result, particle levels will be Moderate. Wednesday, light north-northwesterly winds during the daytime hours will disperse pollutants and gradually transport a cleaner air mass into the Sacramento region. As a result, particle levels will be low-Moderate. Thursday, calm winds throughout the day will reduce pollutant dispersion in the Sacramento region. Furthermore, cool overnight temperatures will produce a temperature inversion, limiting mixing. These conditions will lead to high-Moderate particle levels.
