UNDATED (AP) - A large swath of the U.S. is experiencing frigid temperatures, sleet, snow and ice. Several deaths have been reported, most a result of treacherous driving conditions. More than a thousand flights have been canceled, numerous football and basketball games postponed and holiday celebrations - including tree lightings and parades - curtailed.
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.
Primary roads were usable if motorists could maintain a head of steam, but once they stopped, it was difficult to get going again, said Randy Ort, a spokesman for the Arkansas Department of Highway and Transportation.
Additional sleet or snow is expected Saturday night and Sunday.
Xcel Energy crews are working in bitter cold temperatures to restore natural gas service to 7,200 customers in a part of Boulder County.

The outage came just as a winter blast brought snow and single-digit temperatures to much of Colorado.
Temperatures ranged from the single digits to nearly 20 degrees in Iowa on Saturday, and snow was in the forecast.
Western Iowa will see 4 to 5 inches of snow, while the rest of the state is likely to get 1 to 3 inches.

Carlsbad has set up a temporary housing shelter for the homeless because of the freezing temperatures.
The subzero temperatures aren't a problem for Fargo residents. But for those who have come to cheer on South Carolina-based Furman take on North Dakota State in a Football Championship Subdivision playoff game, it's nearly unbearable.
One mother came from Nashville, Tenn., to watch her son play for Furman. She told WDAY-TV that the 20-below zero temperature took her breath away and it hurt to breathe.
The Oklahoma Department of Transportation said many roads were still slick and hazardous on Saturday.
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.
The temperatures won't, however, keep away the state's most unwelcome visitors. Forestry officials say the mountain pine beetles that have ravaged the Black Hills in recent years can withstand the arctic temperatures, which have approached 20 below zero in some areas.
