A large part of the South remained in winter's icy clutches on Friday as snow, sleet and freezing rain was expected from Texas into Louisiana and further east.
Across the Lone Star State, frozen precipitation has turned streets into ice rinks. In response, schools have been closed across the Gulf Coast region.
Texas officials likened weathering the storm to preparing for a major hurricane.
"This is the first thing since Ike as far an emergency that's shut down our operations," Galveston City Manager Steve LeBlanc said.
In Dallas, a large party tent at the Cotton Bowl Stadium collapsed Tuesday under the weight of heavy snow.
"If it was going to happen one day, this was probably a good day," Tony Fay of the North Texas Super Bowl Host Committee told Dallas-Forth Worth affiliate KXAS. "It's a little quiet today. It starts to pick up steam as the week goes on."
The wicked winter weather has also forced the cancellation of most flights at Houston's Bush Intercontinental Airport, leaving weary travelers stranded.
"My flight was canceled," one traveller complained. "I wasn't even notified. They rescheduled it for Sunday night."
Meanwhile, icy roads turned deadly in northeastern Oklahoma where three people were killed Thursday when their pickup truck slid off a snow-covered Interstate 44, plunging 80-feet into the icy Spring River.
As temperatures dipped into the single digits, thousands of people in New Mexico remain in the dark and without heat due to a natural gas shortage.
"It's just horrible right now," one New Mexico resident said. "Nobody in the area has gas."
Forecasters predicted warmer temperatures for Dallas region over the weekend. The weather on Super Bowl Sunday is expected to be near 50 degrees.
