Delmarva is entering a prolonged stretch of hot and very humid weather that will continue through at least Tuesday. Daily chances for showers and thunderstorms will accompany the heat, with some storms capable of producing damaging wind gusts, torrential rainfall and localized flash flooding. A weak cold front Sunday may provide a brief break from the oppressive humidity before moisture surges back Monday and Tuesday. A stronger front could finally bring more noticeable relief by late Tuesday or Wednesday.
