Here is information posted this morning from the Official Twitter Account for National Weather Service Baltimore/Washington:

As Tropical Depression Fred passes off to the west, there will be a threat for isolated tornadoes, damaging winds, as well as flash flooding. The risk for severe thunderstorms may come as early as the mid-morning. Otherwise, conditions should improve by late this evening.
