Sunday promises to be a picture-perfect day across Delmarva with sunny skies, comfortable temperatures, and refreshing breezes. A pair of cold fronts will bring crisp, dry air into the region through Sunday night, paving the way for a calm and cool start to the week. High pressure will dominate Monday and Tuesday with clear skies and seasonal temperatures, but by midweek, a more unsettled weather pattern returns. Rain is expected Wednesday into Thursday, with cooler-than-normal temperatures prevailing into the weekend.
