Monday, as a low-pressure system moves through the Sacramento region, widespread rain showers and periods of moderate winds will keep pollutants well dispersed, yielding Good particle levels. Tuesday, rain showers and gusty winds will continue as another low-pressure system impacts northern California, effectively dispersing pollutants and keeping particle levels Good. Wednesday, as the next low-pressure system approaches northern California, scattered rain showers and light to moderate south-southwesterly winds will disperse pollutants and keep the atmosphere well mixed. These weather conditions, combined with low pollutant carryover from previous days, will lead to Good particle levels.
