Air Quality Forecast and Weather Discussion
Monday, upper-level low pressure will aid atmospheric mixing in the Sacramento region. In addition, regional pollutant carryover from the weekend will be low. Therefore, despite light winds limiting pollutant dispersion, ozone levels will be high-Good. Tuesday, temperatures in the mid- to upper-90s will enhance ozone formation in the Sacramento region. However, light northwesterly winds will aid dispersion. As a result, ozone levels will be Moderate. Wednesday, triple-digit temperatures will increase ozone production in the Sacramento region, and light southwesterly winds will limit mixing and dispersion. These conditions will lead to high-Moderate ozone levels.
