More than 100,000 customers in the Dallas area were without power Saturday, with about 7,000 in Oklahoma and thousands of more in other states.

A treacherous section of icy Interstate 35 about 50 miles north of Dallas has been closed intermittently for as long as five hours as tractor-trailers were unable to climb a hill and then clog the busy highway, Texas Department of Transportation spokeswoman Michelle Releford said Saturday. The backup sometimes extended for mile.
Jody Gonzalez, chief of Denton County Emergency Services, said about 200 people were in shelters in the Sanger area after getting stuck on the highway. People in that area of I-35 were driving through ruts in 4-inch-thick ice, he said.
Releford said road graders and more sand and salt trucks were being sent to try to ease the ice problems.
"We're sending in everything we've got," said Releford
Freezing rain and sleet are likely again Saturday night in Memphis, Nashville and other areas of Tennessee before the storm starts surging northeast.
"It looks like we're going to be stuck with this for one, two, maybe three days," said Memphis attorney Sam Chafetz, who was going home early to enjoy some bourbon-soaked sweet potatoes left over from Thanksgiving.
"I'm not afraid of the ice and snow, I'm afraid of the other drivers who don't know how to drive in it," Chafetz said.
In Virginia, state Emergency Management spokeswoman Laura Southard said the storm had the potential to be a "historic ice event."

Meanwhile, around 7 inches of snow fell in northeast Arkansas and the Missouri boot heel, according to the National Weather Service in Memphis, and 8 to 9 inches fell in parts of southern Indiana.

Looking ahead, the National Weather Service says a wind chill advisory is in effect for parts of northeast Arkansas and the Missouri boot heel. Forecasters say wind chill readings between zero and minus-5 degrees may occur. Usually in the area, snowstorms are followed by fairly quick rebounds into warm weather, but not this time.
Ice had built up on the windshields and roofs of parked cars throughout Memphis into Saturday. Law enforcement reported an increase in traffic crashes, and scattered power outages affected more than 3,000 people, emergency and utility officials said.

A day after freezing rain, sleet and snow brought most of Arkansas to a near standstill Friday, the sun began to help melt ice on major roadways on Saturday.

Additional sleet or snow is expected Saturday night and Sunday.

Westbound lanes of Interstate 40 were shut down near the Oklahoma-Arkansas state line for nearly 2½ hours early Saturday after a tractor-trailer rig jackknifed. And ODOT warned of hazardous driving conditions on I-35 near the Oklahoma-Texas state line.
The bitter cold snap led to cancelled events and increased calls for furnace repairs.
