A dangerous severe weather threat returned to the Lower 48 on Friday as the Midwest and Southeast saw rounds of showers and thunderstorms.

Tree damage and flooding was reported in Alabama as another complex of storms moves across the Southeast. Winds of nearly 40 mph were reported along the coast of South Carolina before the storms moved out to sea.

No letup for severe summer storms

If it feels like there has been frequent severe weather in the forecast, it's because there has been.

There's no let-up coming for the seemingly endless severe storm threats. Round-after-round of severe weather is expected over the next few days. 

On Saturday, the focus will stretch from the heartland to the Northeast. On Sunday, we reset, and a disturbance will produce severe weather in the Central U.S. That threat area shifts east to the Ohio Valley on Monday. 

While severe weather in summer isn't unusual, getting it day after day is the result of a unique pattern, the FOX Forecast Center said.
