DELMARVA -- Will enjoy a continued stretch of mild and mostly sunny weather to begin the week, thanks to a high-pressure system that remains in control through Tuesday.
Warm above average start to the week, but a big late week cool down.
Daytime highs will range from the mid-70s to low 80s, with comfortable dew points in the 50s to low 60s. Winds will be light out of the south-southwest, around 5 to 10 mph.

As the high slides offshore Monday night, light southerly flow will keep conditions mild with overnight lows in the mid-50s to low 60s. Patchy fog may develop again, though increasing cloud cover should limit how widespread it becomes.
Cold front brings rain Wednesday, then a coastal low could impact Delmarva over the weekend.
By Tuesday, clouds will build from west to east as a cold front approaches the region. Despite the increase in cloud cover, warm-air advection will allow highs to reach the upper 70s and low 80s before rain arrives late in the day. Most of the day will be sunny. The front is expected to bring much-needed rainfall Tuesday night into Wednesday morning, with most areas potentially receiving close to an inch. Thunder is possible, though severe weather and flooding risks remain low.

Looking ahead to the weekend, forecast models suggest a developing coastal low could influence Delmarva’s weather. If high pressure remains dominant, the area could stay dry. Otherwise, the low may track northward, bringing another round of rain late Saturday night into Sunday. For now, there’s a 20 to 30 percent chance of showers to close out the weekend.
