Forecast Discussion: Cleaner air is just now (1 pm) arriving in the forecast area and we will drop back to the Good range by this evening. With continued northwest flow on Thursday, and deep vertical mixing, we expect Good air quality. Extended Forecast: Stagnant conditions on Friday will lead to Moderate air quality. Strong northeast winds and rain on Saturday as a coastal storm moves by offshore. Good air quality is likely on Saturday. -Ryan
