Enjoy your outdoor activities.
Thursday, light and variable winds behind a departing cold front will allow pollutants to accumulate in the Sacramento region. Additionally, evening temperatures in the 40s will produce a temperature inversion, reducing atmospheric mixing. However, cool daytime temperatures will reduce ozone formation, and regional pollutant carryover from previous days will be low. As a result, ozone levels will be Good, and particle levels will be high-Good. Friday, a morning temperature inversion will trap pollutants near the ground, while light south-southeasterly winds early in the day will allow pollutants to build up. By the afternoon, the next cold front will approach northern California, generating stronger onshore winds. These winds will disperse pollutants, keeping particle levels high-Good and ozone levels Good. Saturday, as the next cold front moves through the Sacramento region and departs to the east, morning rain showers will enhance atmospheric mixing, and light north-northwesterly afternoon winds will gradually disperse pollutants. However, winds will become calm in the evening, reducing dispersion and keeping particle levels high-Good.
