Wednesday, an upper-level trough of low pressure will promote atmospheric mixing throughout the day. In addition, regional pollutant carryover will be low. Therefore, despite light winds hindering dispersion, particle levels will remain Good. Thursday, a temperature inversion will hinder low-level mixing early in the day. However, northwesterly afternoon winds will aid dispersion, and carryover from the previous days will remain low. Thus, particle levels will be Good to high-Good. Friday, light southerly winds will limit dispersion and transport regional pollutants into the Sacramento Valley. In addition, warming mid-level temperatures will hinder low-level mixing throughout the day. As a result, particle levels will range from high-Good to low-Moderate.
