Saturday afternoon will kick off a stretch of warm and muggy weather across Delmarva, with partly sunny skies and highs in the 80s. While most of the region should stay dry this weekend, low clouds and patchy fog will return overnight, and a few isolated thunderstorms are possible Sunday over the Eastern Shore. By Monday, an approaching cold front will bring more widespread showers and storms. Temperatures will remain above normal into late next week, with heat indices potentially nearing 100 degrees.
