Weather Conditions:
Tuesday, as the next storm system enters the Sacramento region, widespread rain showers and gusty winds will effectively disperse pollutants. Therefore, particle levels will be Good. Wednesday, surface winds will weaken, limiting pollutant dispersion. However, upper-level low pressure will remain over northern California, enhancing atmospheric mixing. In addition, pollutant carryover from previous days will be low, leading to high-Good particle levels. Thursday, light to moderate southwesterly winds behind the departing low pressure system will disperse pollutants and transport clean air into the Sacramento region, keeping particle levels Good.
