Hail slammed Texas and a tornado damaged homes in Arkansas as a second round of severe storms hit the region Monday.
Unusually large hail fell over parts of north Texas, some as large tennis balls. The Wise County Sheriff's Office told NBC Dallas-Fort Worth that the falling ice damaged several vehicles and injured two people.
And schools will be closed Tuesday in Wylie, near Dallas, after very large damaged several homes and vehicles, the station reported.
While scattered thunderstorms were forecast from Texas to South Carolina on Tuesday, the overall picture would be somewhat calmer, according Dale Eck, director of The Weather Channel's Global Forecast Center.
"There will be some thunderstorms in the South East but the threat of severe weather is down a lot from yesterday," he said. "A tornado or two cannot be completely ruled out but the threat is low."
The storms knocked out power to almost 9,000 customers across Mississippi, electric utilities reported Monday night, while almost 2,800 customers remained without power in Arkansas, where four people were trapped in their homes after a small twister tore through Garland.
"We have some damage here in Miller County," Larry Pritchett, director of the county's Office of Emergency Management, told NBC News. "There were some people trapped in houses that trees have fallen into. It's mostly trees down that caused quite a bit of damage."
"Fortunately no one was injured," he added.
Sixty-five miles east of Garland, lightning strikes sparked three fires in the town of El Dorado, Arkanasas, including one that destroyed a church, officials told NBC News.
Meanwhile, 14 million Americans were in the path of severe thunderstorms in northeastern Texas, southern Oklahoma and southwestern Arkansas, where the National Weather Service issued severe thunderstorm watches into Monday evening.
The watch area includes Dallas, where Dallas-Fort Worth International Airport reported weather-related delays of 31 to 45 minutes.
Keli Pirtle of the National Weather Service said "this is very typical."
"April, May, June are the busiest time of the year for severe weather in this part of the country," Pirtle said.
The northern stretches of Texas and central and southeastern Oklahoma were bombarded Sunday, with smaller hail reported in Kansas and Missouri.
Powerful winds were also recorded across the region. Storm chasers recorded one gust of 90 mph on Interstate 44 near Geronimo, Oklahoma, according to the National Weather Service.
The storm was expected to be "less robust" Wednesday as it moves eastward into Georgia, northern Florida and the Carolinas, The Weather Channel added.
Up in the Northeast, another cold front was expected to come through Tuesday.
"After that, temperatures will be near seasonal with highs in the 60s and lows in the lower 40s," said meteorologist David Wally of the NWS.
In New York City, the coming weekend was already looking promising, with temperatures forecast to be 3 to 5 degrees warmer than usual, Wally said.
