Forecast Discussion: High pressure quickly takes control on Saturday creating inverted conditions and increasing fine particle concentrations to the low-end Moderate range. An approaching warm front Sunday will further trap fine particles close to the surface until the front passes, likely creating fog Sunday and widespread Moderate air quality, especially along the I-95 corridor. The passage of the warm front and associated rain on Monday will reduce fine particle concentrations back to the Good range. Then a cold front on Tuesday will promote Good air quality through Wednesday. - MDE
