A stretch of warm and humid weather will settle over Delmarva through the weekend and into next week. Saturday and Sunday will bring partly sunny skies and temperatures climbing into the 80s, with low clouds and morning fog each day. While most of the region should stay dry through Sunday, a stronger cold front arriving late Monday is expected to trigger more widespread showers and thunderstorms. Highs will remain above normal all week, and heat indices may approach 100 degrees in some locations by midweek.
