Today stays warm and sunny across Delmarva, but temperatures step down from yesterday’s record highs. Cooler air arrives near the coast Saturday as a backdoor front pushes in, while inland areas stay milder. Minor tidal flooding is expected along the Delaware coast and Delaware Bay Saturday evening into Saturday night, followed by showers, a few thunderstorms, and a sharp cool down late Saturday night into Sunday. Much colder air settles in early next week, with widespread frost or freeze conditions likely Monday night into Tuesday morning.
