Forecast Discussion: Monday, an upper-level ridge of high pressure will strengthen over California, reducing mixing in the lower levels of the atmosphere. Therefore, despite light to moderate north-northwesterly winds dispersing some pollutants, particle levels will be Moderate. Tuesday and Wednesday, high relative humidity associated with patchy fog will enhance particle production in the Sacramento area, and light winds will reduce pollutant dispersion. These weather conditions will result in Moderate particle levels on both days.
