Synopsis: An air quality alert has been issued statewide for Thursday July 20th. Mostly sunny skies, favorable WSW flows, and the lack of any widespread afternoon showers should allow ozone to reach UNHEALTHY levels during the afternoon and late into this evening. It's recommended to avoid heavy exertion during those times. Fine particles are expected to reach MODERATE. A cold front approaches overnight, with an increased chance of showers and thunder. The front will linger offshore on Friday, with less humidity, and mostly sunny skies. In the vicinity of the front, ozone is expected to reach MODERATE along the immediate southern coast of the state. An area of low pressure on Sunday will bring the threat of showers and GOOD air quality.
