AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Tuesday, light and variable winds in the Sacramento Valley will hinder pollutant dispersion. However, an upper-level trough of low pressure approaching northern California will enhance vertical mixing in the atmosphere. As a result, particle levels will be Moderate. Wednesday, as the trough passes over northern California, gusty north-northwesterly winds at the surface will effectively disperse pollutants in the Sacramento region, lowering particle levels to high-Good. Thursday, lighter winds will limit dispersion. Additionally, cold morning temperatures will produce a strong inversion, trapping pollutants near the ground. However, low pollutant carryover from the previous day will yield continued high-Good particle levels.
