A stretch of fair, cooler-than-average weather is expected in Sussex County from late Monday through late Wednesday, ahead of heat and humidity returning later this week.

Delmarva starts the week with marine clouds and patchy fog as an onshore flow keeps skies gray and temperatures mild. A cold front will bring showers and a low-end severe threat Tuesday before high pressure brings sunshine and near 90-degree warmth by midweek. Rain chances return by the weekend as another front approaches.

Unsettled weather with thunderstorms and fog is expected in Sussex County from late Friday through Saturday evening, with improving conditions by Sunday.
