Know What You're Breathing
It's almost summer and that means our region will soon be having higher levels of smog, known as ground-level ozone.

Air Quality Forecast and Weather Discussion
Thursday, mostly sunny skies will aid ozone formation in the Sacramento region. However, moderate onshore winds will increase pollutant dispersion, yielding Good ozone levels. Friday, an upper-level trough of low pressure over northern California will enhance atmospheric mixing. In addition, increased cloud cover and cooler temperatures will reduce ozone formation. As a result, ozone levels will remain Good. Saturday, increasing sunshine and warmer temperatures will enhance ozone, and lighter winds will reduce pollutant dispersion. However, pollutant carryover from the previous days will be low. These conditions will lead to low-Moderate ozone levels.
