A coastal system develops off the Carolinas, sliding northeast and moving offshore. Another low pressure system will form to the south, passing near or just west of Delmarva by Thursday night, pushing a cold front through the region.
High pressure offshore will keep Delmarva dry and warm, but increasing clouds signal a strong cold front approaching overnight. Expect rain and a few rumbles of thunder late tonight into Wednesday morning before temperatures drop sharply midweek. Cooler, breezy, and dry conditions will follow through Friday, with patchy frost possible inland Thursday night.
