Sunday, sunny skies will support ozone formation and periods of light onshore winds will hinder dispersion. However, a trough of low pressure aloft passing over the region will enhance atmospheric mixing. Thus, ozone levels will be Good. Labor Day, sunny skies and temperatures warming into the low-90s will increase ozone formation, while mixing will decrease behind the departing upper-level trough. Therefore, despite low pollutant carryover from the prior days, ozone levels will be low-Moderate. Tuesday, calm to light onshore winds will allow ozone precursors to accumulate. Additionally, ample sunshine and temperatures in the low-90s will continue to support ozone development. As a result, ozone levels will increase to mid-Moderate.
