Sunday will be hot and humid across Delmarva with temperatures rising into the upper 80s and low 90s and heat index values between 100 and 104 degrees. A cold front approaching from the northwest could trigger isolated storms late in the day, some of which may become severe. After the front moves through, high pressure will bring more comfortable and dry conditions through Wednesday before heat and humidity return late in the week.

High pressure will keep Delmarva dry and unseasonably warm through Tuesday, with mild overnight temperatures and potential patchy fog. A warm front lifts north overnight, followed by clearing skies and above-average temperatures on Tuesday.

Tonight, Delmarva will experience clear skies and calm conditions, with temperatures dropping into the mid to upper 50s. Saturday will bring slightly warmer weather with highs reaching the mid-80s as high pressure shifts offshore, leading to a light southwesterly breeze.

A potent upper-level trough will bring increased chances of showers and thunderstorms to Delmarva on Friday evening, with continued stormy and humid conditions expected throughout Saturday.
