Forecast Discussion: Clouds are on the increase Friday limiting ozone production. Most areas will have Good air quality with easterly winds, though areas west of I-95 may see fine particles flirt with the low Moderate range as the state will be under an inversion and winds fade later in the day. A weak front moves through early Saturday morning with northerly winds behind it and clearing skies. This will help maintain Good air quality on Saturday, though a few areas in the morning may have elevated fine particle concentrations. For Easter Sunday, sunny skies dominate. Winds turn towards the east, ushering in clean air and maintaining Good air quality. - MDE
