Detailed Forecast


Synopsis: A front over the area will slowly sag southward through Saturday as high pressure builds in from the north and west. Several waves of low pressure will develop along this boundary and pass south and east of New Jersey through the weekend. High pressure tries to establish itself over the area early in the new week. The old frontal boundary then lifts north as several areas of low pressure develop on it and approach from the south late next week.
