A deadly storm that pummeled the southern United States over the weekend was threatening millions of people across the mid-Atlantic on Sunday night with severe thunderstorms, powerful winds and possible tornadoes, the National Weather Service said.
The same storm caused havoc at Chicago's O'Hare International Airport, where a blast of wintry weather dumped nearly half a foot of snow on Sunday, according to NBC Chicago.
