Monday and Tuesday, mostly sunny skies and temperatures in the 90s and low-100s will aid ozone development. In addition, smoke from regional burning will contribute to particle concentrations. Therefore, despite periods of moderate southwesterly winds aiding dispersion, AQI levels will be low-Moderate in most locations. Wednesday, southwesterly winds will weaken slightly, reducing dispersion. Furthermore, mostly sunny skies and temperatures around 95-100F will continue to support ozone formation. These conditions will yield low-Moderate AQI levels statewide.
