Sunday and Monday, as a surface ridge of high pressure builds over the Sacramento region, light and variable winds will allow pollutants to accumulate. In addition, temperature inversions will limit mixing each morning and evening, while thin smoke from scattered agricultural fires contributes to particle levels. As a result, particle levels will be mid-Moderate on both days. Tuesday, as the surface ridge shifts north of Sacramento, a slight increase in northwesterly winds will aid dispersion and gradually transport cleaner air into the region. Furthermore, highs in the mid-70s will promote mixing in the afternoon, leading to low-Moderate particle levels.
