Severe weather will continue to overspread areas from Kentucky east through the mid-Atlantic into tonight.
The big cities across the mid-Atlantic were already pounded by these powerful thunderstorms and locations stretching from eastern Kentucky to the Delmarva Peninsula should be on alert.
Residents of these areas should monitor the progress of these storms and take the necessary precautions when threatening weather is imminent.
The thunderstorm rains have also had a tremendous cooling effect. The temperature at Wilmington, Del., fell 17 degrees in only 15 minutes when a thunderstorm struck.
The strongest thunderstorms will continue to produce damaging winds in excess of 60 mph, hail and flooding downpours that will quickly reduce driving visibility. An isolated tornado or two could touch down and cause destruction.
Those across recreational areas, including shore points, will want to keep an eye to the sky and seek safe shelter at the first sign of a thunderstorm.
The storms are associated with a cold front which will help significantly lower humidity values across the Northeast and mid-Atlantic for Monday.
As the front pushes south, storms will fire again for the beginning of the workweek from the central Plains east through the Carolinas.
