A large swath of the U.S. has frigid temperatures often with sleet, snow or ice - or a combination of all three. Several deaths have been reported, most a result of treacherous driving conditions. 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, the sun began to help melt ice Saturday on major roadways. 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. A company spokesman says an equipment failure at a regulator station was repaired Friday afternoon, but crews must go door-to-door to restart customers' pilot lights. 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. The National Weather Service says lows will hover around zero at the beginning of the week and dip lower on Wednesday. Parts of north Mississippi faced a winter weather advisory Saturday night into Sunday as a second wave of freezing rain moves into the region. The National Weather Service said ice accumulations are not expected to exceed one-tenth of inch - enough for motorists to be cautious with overnight temperatures dropping in the upper 20s to near freezing. Like many states, Missouri experienced temperatures in the single digits Saturday. The National Weather Service said the Kansas City International Airport tied a record low Saturday morning - just 1 degree. The weather didn't stop the St. Jude's Frostbite Half/Full Marathon in Cape Girardeau, about 120 miles southeast of St. Louis. Twenty-six heavily bundled participants turned out for the race, which at its start was 11 degrees. Frigid temperatures are expected to hang around Nebraska through the weekend and into next week, while another storm system will bring anywhere from an inch to 4 inches of snow to central and eastern parts of the state. Freezing rain and slick patches made driving conditions dangerous Saturday on Interstate 40 in eastern New Mexico and Interstate 25 near Raton. Meanwhile, the National Weather Service says northern and southwestern New Mexico will see snow late Saturday into Sunday, with wind gusts up to 50 mph. 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.
