Forecast Discussion: Increasing humidity with light winds in the morning, coupled with transport aloft from the west, will allow particle concentrations to increase into the Moderate range on Saturday. Extended Forecast: A cold front will cross Delaware early Sunday and cool, dry air will arrive immediately in its wake. Air quality will improve to the Good range. Particle concentrations will increase on Monday due to limited vertical mixing but a clean start to the day will ensure that this increase will be limited to the upper end of the Good range. -Ryan
