JACKSON, Miss. - A large storm system packing high winds, rain and some possible twisters tore across several states in the South and central U.S. early Wednesday, blacking out power to thousands, downing trees and damaging homes.
At least one person was reported injured by lightning in Arkansas during the storm's eastward trek, marking onslaught of an approaching cold front expected to sweep over a large part of the East Coast in coming hours.
The rapidly changing conditions created a risk of tornadoes in the nation's midsection and South. The National Weather Service's Storm Prediction Center in Norman, Okla., said the threat was greatest in northeast Texas, northern Louisiana, northwest Mississippi, southeast Missouri and much of Arkansas.
Entergy Arkansas Inc. reported at least 9,000 power outages in several communities around Arkansas at the height of the storm, including in and around Little Rock.
Authorities in Arkansas said they would be checking reports of possible twisters kicked up near a Little Rock suburb and in two locations in northwestern Arkansas. Power lines fell, trees were toppled and some homes suffered damage to rooftops around the state, according to emergency officials.
The National Weather Service reported that suspected straight-line winds of up to 80 mph were reported in Arkansas late Tuesday night along with flooding in low-lying areas of Jonesboro in Arkansas' northeastern corner. Police in the Arkansas community of Monticello reported a person was injured by lightning late Tuesday but the injury was not life-threatening.
The Mississippi Emergency Management Agency urged residents to be on guard for severe thunderstorms, high winds and the possibility of tornadoes amid the collision of cold and warm weather systems.
"This storm will move through the state while most folks are asleep, which increases the potential for injuries," said the agency's director, Robert Latham, urging Mississippi residents to stay tuned to weather alerts Wednesday.
Tennessee also braced for volatile weather conditions from the front stretching on a slanted arc crossing several states. In Tennessee, a tornado watch was in effect for a wide swath of the state overnight, part of a system that spread buffeting winds and rain over the region.
Earlier this week, a large swath of the Midwest and South bathed in unseasonably balmy temperatures that reached the high 70s in some areas.
The temperature in the central Missouri college town of Columbia reached 77 degrees on Monday, a record for January, and students exchanged their winter coats for shorts and flip-flops as freezing rain gave way to spring-like conditions. Foul weather made a quick return, however, with a Tuesday downpour that flooded some streets near the University of Missouri campus. Early morning snow was expected Wednesday.
Chicago residents also have been whiplashed by recent weather extremes. Workers who suffered through subzero temperatures and brutal wind chills a week ago strolled through downtown without coats Tuesday as temperatures soared into the mid-60s.
Carol Krueger, who lives in the Chicago suburb of North Hoffman Estates, noted that just a few days ago she was struggling to drive through blowing snow. All she needed Tuesday was a light jean jacket, although by Thursday temperatures were barely expected to reach 20 degrees.
"It's bizarre, it's scary," Krueger said of the swiftly changing weather.
On Monday, the National Weather Service predicted a "moderate" risk of severe weather more than 24 hours out, only the fifth time it had done so in January in the past 15 years, said Gregory Carbin, the director of the Storm Prediction Center.
A system pulling warm weather from the Gulf of Mexico was colliding with a cold front moving in from the west, creating volatility.
The nation has had its longest break between tornado fatalities since detailed tornado records began being kept in 1950, according to the Storm Prediction Center and National Climatic Data Center. The last one was June 24, when a person was killed in a home in Highlands County, Fla. That was 220 days ago as of Tuesday.
The last day with multiple fatalities was June 4, when three people were killed in a mobile home in Scott County, Mo.
