Forecast Discussion: High pressure in place on Saturday will create Moderate threshold conditions throughout the state due to reduced mixing. A moderate increase in wind with an approaching front on Saturday will allow a few areas of Moderate air quality along the I-95 corridor, but otherwise Good air quality. Weak winds on Tuesday, especially above the surface, will lead to Moderate conditions but strong mixing by Wednesday will return the region to Good air quality. - MDE
