A stalled front keeps Delmarva dreary and foggy today, with the coolest, foggiest weather hugging the coast while inland areas briefly break into sunshine and warmer temperatures. Fog and drizzle linger into tonight and early Friday, then a backdoor cold front reinforces cooler, cloudier conditions. The pattern flips this weekend as warmer air pushes back in, turning noticeably milder Sunday and especially early next week with a few chances for showers and even a thunderstorm.
