Air Quality Forecast and Weather Discussion
Monday, moderate and gusty northerly winds will disperse pollutants throughout the day, leading to Good particle levels. Tuesday, northerly winds will aid dispersion through the morning hours. However, pollutants will gradually accumulate in the evening as winds weaken and shift to southerly. In addition, a ridge of high pressure aloft will move over northern California, reducing mixing. Therefore, particle levels will be Moderate. Wednesday, the upper-level ridge of high pressure will remain over northern California, inhibiting mixing in the atmosphere. Furthermore, light and variable winds will limit dispersion, allowing pollutants to accumulate in the Sacramento region. As a result, particle levels will be high-Moderate.
