After Thursday's deadly severe weather outbreak, more damaging thunderstorms are threatening the mid-Atlantic, Southeast and Ohio Valley as this workweek comes to a close.

The corridor from Philadelphia to Atlanta with a separate area around Ohio are at risk for damaging storms packing strong winds, torrential rain and even some hail into this evening.

Other cities in the above threat zones include Charlotte and Raleigh, N.C., Norfolk and Richmond, Va., Washington, D.C., Dover, Del., Pittsburgh, Pa., Cincinnati and Columbus, Ohio, Detroit, Mich., and Louisville, Ky.

For the Ohio Valley, the impending violent thunderstorms come as residents are still cleaning up from Thursday's damaging thunderstorms.

Fortunately, the scope and magnitude of Thursday's outbreak should not be duplicated into this evening.

The strongest thunderstorms will be more scattered in nature. However, it should be stressed that it only takes one powerful thunderstorm to cause damage and bodily harm.

Thunderstorms are a common occurrence across the eastern half of the United States this time of year, but the magnitude of the storms into this evening may catch those starting their weekends early off guard.

Powerful wind gusts in excess of 50 mph, high enough to bring down tree limbs and power lines, will accompany some storms. The strong winds combined with heavy rain will reduce visibility to nearly zero for some motorists.

Damage ranging from downed trees and torn off roofs from these violent thunderstorms have already been reported.

Localized flash flooding are another danger from the downpours. Places in the Ohio Valley that have missed out on rain recently are especially at risk since the ground is too hard to initially soak up the heavy burst of rain.

Some small hail could be coupled with the storms as well, but the stones should not be large enough to cause any major damage.

The severity of the thunderstorms will wane by early Saturday morning, but a new severe weather threat lurks for North Carolina and southern Virginia for Saturday afternoon.
