Monday, September 28: Cool aloft temperatures will support mixing as an upper-level trough of low pressure passes over the northern Sierra. Therefore, despite lighter surface winds limiting dispersion, AQI levels will remain Good. Tuesday, September 29 and Wednesday, September 30: Calm to light easterly winds will hinder dispersion. However, afternoon high temperatures in the upper-70s to low-80s will promote vertical mixing, keeping AQI levels Good on both days. Thursday through Saturday, winds will shift to west-southwesterly and strengthen each afternoon, aiding dispersion. Furthermore, warm afternoon temperatures will support mixing, yielding continued Good AQI levels on all three days.
