Air Quality Forecast and Weather Discussion
Sunday and Monday, upper-level high pressure over Northern California will reduce vertical mixing. In addition, sunny skies, hot temperatures, and light winds will enhance ozone formation. These conditions will cause ozone levels to increase, resulting in high-Moderate AQI levels Sunday and low-Unhealthy for Sensitive Groups AQI levels Monday. Tuesday, upper-level high pressure will weaken, leading to stronger southerly winds and cooler temperatures. These conditions, along with carryover pollutants, will lower ozone levels to low- to mid-Moderate.
