A beautiful Thursday is ahead across Delmarva with hazy sunshine, highs in the upper 80s to low 90s and a refreshing sea breeze developing at the beaches. A cold front will continue pushing south through Friday, opening the door to cooler and less humid weather for Saturday and the first half of Sunday. Showers and thunderstorms return to the forecast Sunday afternoon into Monday, while spotty minor tidal flooding is possible during Thursday evening’s high tide along portions of the Delaware coast and Delaware Bay.
