High pressure offshore will keep Delmarva dry and warm, but increasing clouds signal a strong cold front approaching overnight. Expect rain and a few rumbles of thunder late tonight into Wednesday morning before temperatures drop sharply midweek. Cooler, breezy, and dry conditions will follow through Friday, with patchy frost possible inland Thursday night.

Delmarva can expect pleasant, mostly sunny weather through Tuesday with highs in the 70s to low 80s before a cold front brings widespread rain Tuesday night into Wednesday. The front will usher in cooler, fall-like temperatures for the end of the week, with highs returning to the 60s and a potential for frost in inland areas by Thursday night.

A coastal low will produce unsettled weather through midweek with mostly cloudy skies, periods of showers, and gusty northeast winds. Highs will stay in the upper 60s to low 70s with lows in the 50s to 60s. Rain will be heaviest Tuesday night into Wednesday morning, bringing 1 to 2 inches of precipitation and occasional thunder. Conditions will improve by Thursday, with drier and warmer weather returning late week and highs climbing into the 80s before a dry front cools temperatures over the weekend.

Temperatures gradual tumble Sunday afternoon after above-average warmth across Delmarva, a cold front ushers in steady rain overnight into Monday.  A drastic drop in temperatures begins Monday, with widespread 40s and gusty winds expected by Tuesday. Conditions will remain dry but chilly midweek, before a potential return of rain on Friday.
