DELMARVA - A coastal low over the mouth of the Chesapeake will remain nearly stationary into Wednesday night, gradually weakening as it shifts slowly northeast off the coast by Thursday. Skies will stay mostly cloudy, with periods of showers and cool air near the surface. A cold front will pass through Friday, with high pressure building in behind it, bringing warm and dry conditions into the weekend.

Northeast to east winds around 10-20 mph, with gusts possibly reaching 25 mph. Temperatures in the upper 60s to low 70s. Overnight lows from the mid-50s to mid-60s. Fog and low clouds expected to linger.
Thursday
