The showers and thunderstorm activity will diminish for the Mid-Atlantic and Northeast regions on Tuesday as the cold front pushes offshore. The remnants of Bonnie are forecast to linger off the North Carolina coast into Wednesday morning, which will maintain chances for showers and thunderstorms across the Southeast.
