The National Weather Service is warning of a powerful line of gigantic thunderstorms that are rolling out of the Mid-West and are expected to hit Maryland and packing some hail lightning and tree-toppling winds.
They’re called a derecho with winds that could span 240 miles.
The storms are likely to generate tornados and cause power outages followed by oppressive heat.
Meteorologist Mitchell Gaines, National Weather Service:
If the storm remains intact after crossing the Appalachian Mountains, it should hit the Washington area by late afternoon or early evening.
The National Weather Service says for parts of the Mid-Atlantic the big storm risk continues and even increases a bit Thursday.
