High pressure moving off the New England coast will allow winds to freshen from the south, bringing noticeably milder air. Patchy clouds and fog early Sunday morning will give way to mainly sunny skies across the entire region. The sunshine and southerly winds will cause temperatures to rise well into the 60s. Skies will remain mainly clear in the evening, however some clouds will arrive later at night as low-level moisture increases ahead the approaching cold front.
Monday will remain very mild. Despite limited sunshine, temps will reach the 60s once again. Much, if not all of the day, will be dry. Monday night will be cloudy. A spotty shower could occur through midnight, with more widespread showers expected after midnight as the aforementioned cold front moves across Pa. and reaches the Northeast Seaboard around sunrise Tuesday. Showers will continue Tuesday morning and it will turn much cooler. Drier air will return for the afternoon, ending the rain and allowing for brighter conditions to return before sundown.
