Saturday, an upper-level ridge of high pressure over the state will limit atmospheric mixing. Furthermore, a strong temperature inversion will hinder low-level mixing during the morning and evening hours. However, periods of light northwesterly winds will aid dispersion and transport cleaner air into the Sacramento region during the afternoon, keeping particle levels low-Moderate. Sunday, dispersion will decrease as northwesterly winds diminish in response to a surface ridge of high pressure developing over the Sacramento region. In addition, areas of fog during the morning and evening will promote particle formation, leading to mid-Moderate particle levels. Monday, atmospheric mixing will decrease as a ridge of high pressure aloft strengthens over northern California. In addition, a strong temperature inversion during the morning and evening hours will confine pollutants near the surface, while light and variable winds limit dispersion. Furthermore, areas of fog will aid particle production, leading to high-Moderate particle levels.
