2018 is off to a frigid start for vast swaths of the U.S.
From Texas to Ohio, temperatures are 15 to 25 degrees lower than average, the National Weather Service says. Brutally cold temperatures continue in the Northeast. There's a hard freeze warning across the Deep South — and a chance of snow in New Orleans.
It's 17 degrees in Atlanta. There's a low of 14 degrees in Tupelo, Miss. In Dallas, temperatures will stay below freezing all day.
