Delmarva starts the week with partial sunshine and seasonable temperatures, but a shift to wetter weather begins Monday night. Rain and occasional thunderstorms are expected through midweek, followed by another wave of unsettled conditions Friday and Saturday as back-to-back cold fronts sweep through the region.

Mother's Day brought blue skies and temperatures in the low 80s across the Delmarva Peninsula, but the region will soon trade sun for showers as a series of low-pressure systems and cold fronts approach. Rain chances increase starting Monday night, with several rounds of wet weather expected through Saturday.
