Delmarva stays locked under clouds today as a backdoor cold front keeps temperatures chilly, especially near the beaches. Fog and drizzle develop tonight, then milder air builds in this weekend with partial clearing Saturday afternoon, a chance for showers overnight Saturday into Sunday, and much warmer temperatures arriving early next week.

A stalled front and weak low pressure system will keep clouds and scattered showers over Delmarva Sunday, with highs only in the low to mid-70s. Conditions improve Sunday night as high pressure builds in, bringing dry and seasonable weather to start the week. A weak coastal low could bring more clouds midweek, while a warm, dry Thursday is followed by another cool and comfortable weekend.

Clouds and scattered showers linger across Delmarva Sunday as a nearly stationary front and weak low pressure system pass through the region. Highs will remain cool, in the low 70s, before conditions clear late in the day. Dry weather and seasonable temperatures return Sunday night into Monday, with partly sunny skies and highs in the mid-70s. A weak coastal low could increase cloud cover Tuesday into Wednesday, followed by a stretch of dry, pleasant weather for the latter half of the week.

High pressure will keep Delmarva under mostly sunny skies Sunday, with highs in the mid to upper 70s and a low rip current risk. The tranquil weather pattern will carry through Labor Day, but a chance of showers develops by Thursday as a cold front approaches.

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.
