Winter advisories are underway from Texas to the Ohio Valley as sleet and freezing rain create dangerous ice conditions.
Yikes, talk about mood swings.
A particularly brutal batch of Arctic air has taken hold across the center of the country, bringing sub-zero temps to the north and sleet as far south as central Texas.
"The weather is bad and getting worse," said Oklahoma Gov. Mary Fallin, who declared a state of emergency Thursday because of the storms.
“It could be the worst ice storm to hit the region since 1994, which caused over $3 billion in damage,” reports CNN Meteorologist CNN’s Indra Petersons.
Roads were slick and dangerous in some parts of the state, where officials reported three dozen storm-related injuries, including 16 falls. The Oklahoma Highway Patrol responded to more than 50 weather-related accidents.
“It will be a very slow and treacherous commute this morning,” reports CNN’s Alina Machado. (SEE VIDEO BELOW)
“More than 100,000 people are waking up today in north Central Texas without power and that number could rise if this continues.”
The wintry mix is expected to continue through the weekend.
For the first time in its 26-year history, a downtown Dallas holiday parade scheduled for Saturday was canceled.
The Dallas Marathon, which typically attracts 25,000 runners, plus family and friends, is still expected to run on Sunday.
Oklahoma and Texas are not the only states affected. Tennessee has also declared a state of emergency.
According to an experimental ice impact index by the National Weather Service, this could be a category 3 ice storm in Memphis, Petersons says.
