It all started late Friday morning outside Chicago as a cluster of thunderstorms, says the Weather Channel. The bad weather plowed south and east, hitting Indiana, Ohio, Kentucky, West Virginia, Virginia, Maryland, the District of Columbia and New Jersey.
Increasingly violent storms downed power lines, yanked roofs off houses and toppled trees that crushed people beneath them. Several states declared states of emergency and President Obama signed a disaster declaration for West Virginia.
Friday's storms didn't cool temperatures — in fact, the Weather Service expects record-high temperatures to continue from the Mississippi River valley up through the Mid-Atlantic states.
