The National Weather Service issued an extreme cold warning for 11 states, from the Canadian border to Oklahoma and central Texas, with wind chills expected to bring life-threatening, sub-zero temperatures.
States along the Rockies and Northern Plains were hit by the polar vortex Monday, with ice and snow in Nebraska and Michigan, and temperatures as low as -60°F in North Dakota and -50°F in Montana.
The storm is expected to move into the South and East on Wednesday before heading out to the Atlantic on Thursday. Major snowfall is likely in the Ozarks, North Carolina, and Virginia, with possible ice storms in North Carolina.
Kentucky is also in the storm’s path, with snow expected to reach the Bluegrass State late Tuesday, hindering recovery efforts from recent flooding that killed at least 11 people and left thousands without power.
