3/27 - A cold front is expected to impact the region Thursday night into Friday morning, bringing the chance for heavy rain/isolated thunderstorms and a northerly wind shift. Combined with temperatures rapidly dropping into the 40s, ozone levels will be able to return to the good category statewide, while levels of fine particulate linger near the good/moderate threshold in southern New Jersey. 3/28 - Unseasonably cool temperatures and brisk northwesterly winds will help to keep air quality in the good category across New Jersey on Saturday. 3/29 - High pressure over the region will allow for milder temperatures in the mid 50s on Sunday, along with mostly sunny skies and breezy southwesterly winds. Levels of fine particulate will approach the good/moderate threshold statewide as a result, while ozone remains good. 3/30 - Air quality is expected to increase to the good/moderate threshold statewide on Monday due to increasing temperatures, partly sunny skies, and persistent southwest winds.
