Air Quality Forecast and Weather Discussion
Friday, a morning temperature inversion will reduce vertical mixing in the atmosphere over the Sacramento region. In addition, calm to light southwesterly winds throughout the day will limit dispersion. As a result, particle levels will be mid-Moderate. Saturday, southerly to southwesterly winds will strengthen, increasing mixing and dispersion. However, these winds may bring additional pollutants from the northern San Joaquin Valley into the Sacramento region. As a result, particle levels will remain mid-Moderate. Sunday, southerly winds will weaken and become calm late in the day, reducing dispersion and allowing pollutants to accumulate. Therefore, despite a weaker overnight inversion, particle levels will be high-Moderate.
