Air Quality Forecast and Weather Discussion
Saturday and Sunday, an upper-level trough of low pressure over northern California will enhance vertical mixing in the atmosphere and generate breezy southerly winds in the Sacramento region. These weather conditions will effectively disperse pollutants, yielding Good particle levels on both days. Monday, an upper-level ridge of high pressure will build over the region, decreasing atmospheric mixing. However, light northerly winds will aid pollutant dispersion, and pollutant carryover from the previous days will be low. As a result, particle levels will be low-Moderate.
