Forecast Discussion: The strong cold front that was scheduled to reach southeastern PA on Sunday has slowed down, and now will not approach Delaware until Monday. As a result, Sunday will be another warm and humid day, with scattered clouds and a chance for afternoon thunderstorms. Sustained onshore transport aloft will keep clean maritime air flowing into state, for continued Good air quality on Sunday. **Extended Forecast: As the cold front stalls over Maryland on Monday and slowly moves eastward into Delaware on Tuesday, clouds, rain, and thunderstorms will impact the state. Locally heavy precipitation will be possible, particularly on Monday afternoon into Tuesday morning. Good air quality will continue. -Huff
