Forecaster's note
Wednesday, a ridge of high pressure aloft will produce sunny skies with temperatures near 100F. These conditions, combined with lingering thin smoke from regional fires, will enhance ground-level ozone formation. As a result, ozone levels will be high-Moderate. Thursday, a strong morning temperature inversion will confine pollutants and ozone precursors near the ground. In addition, ample sunshine and afternoon temperatures near 100F will continue to promote ozone development, while remnant thin smoke will enhance ozone production. Thus, ozone levels will be Unhealthy for Sensitive Groups. F
