Air Quality Forecast and Weather Discussion
Monday, an upper-level ridge of high pressure will weaken over northern California, increasing vertical mixing in the atmosphere. However, generally light winds will limit pollutant dispersion, leading to Moderate particle levels. Tuesday, an upper-level trough of low pressure over northern California will enhance atmospheric mixing in the Sacramento region. In addition, light to moderate southwesterly to northwesterly winds will increase pollutant dispersion. As a result, particle levels will be low-Moderate. Wednesday, gusty north-northwesterly winds will effectively disperse pollutants in the Sacramento region, lowering particle levels to Good.
