Overnight and early morning rain and high winds that are part of a cold front have caused tough driving conditions, a slew of power outages and a confirmed tornado in Arkansas.
At one point Thursday morning nearly 6,000 MLGW customers in Shelby County, Tenn., were without power due to the high winds.
In Arkansas, though, than 46,000 electric customers are without service following a storm system that blew through overnight and left behind powerful wind gusts.
Arkansas' largest electric utility, Entergy Arkansas, says nearly 41,000 customers are without power Thursday. About 11,500 of them are in the Little Rock area.
Traffic was slowed in places across Little Rock as many traffic lights weren't working.
Arkansas Electric Cooperatives utilities say nearly 4,000 customers of First Electric Cooperative are without lights. South Central Electric Cooperative has almost 1,700 customers lacking power.
Among the areas served by Entergy, Garland County has 5,000 out, and Union County has about 2,800 dark.
Dozens of other counties had outages numbering from handfuls to more than 1,000 customers without lights.
A survey team from the National Weather Service said a tornado touched down near Sheridan, Ark.
The tornado hit just southwest of Sheridan in Grant County early Thursday, destroying at least one mobile home. Survey crews also intended to check for possible tornado damage in Arkansas and Monroe counties in eastern Arkansas.
Entergy Arkansas reported more than 46,000 electric customers were without power late Thursday morning. The Arkansas Electric Cooperatives also reported several outages, but said it was difficult to say how many as some people lost power as other services were restored.
Forecasters said a tornado may also have hit northeast of Lavaca in far western Arkansas, with homes and a fire station damaged.
In Mississippi, severe thunderstorm and tornado watches and warnings spread across the Magnolia State on Thursday along with a fast-moving storm with winds up to 60 miles an hour in some places.
The National Weather Service says some watches and warnings would continue into the afternoon and evening.
Forecasters say after the front passes, it will be clear and gusty with temperatures failing to near freezing in many areas.
There were no immediate reports of damage.
