Millions of Americans were bracing for facing bone-chilling temperatures on Tuesday as winter weather made another push into spring.
Freeze warnings were in effect across large swathes of the Northeast while forecasters warned that parts of the Midwest could see up to 8 inches of snow.
Tuesday's wintery weather comes as parts of the country were still digging out from deadly storms and unusual April snowfall.
While the Northeast won't see snow on Tuesday, "well-below normal temperatures" across the eastern U.S. could set records, according to the National Weather Service.
It said afternoon high temperatures were expected to be 10 to 20 degrees below average.
Freeze warnings stretched from North Carolina to New York on Tuesday, threatening early spring blossoms that had made their appearance during warm March weather.
"Of great concern are the early blossoms of apple and peach trees in the Mid-Atlantic region," NBC News meteorologist Bill Karins said.
Tuesday's temperatures could challenge record lows for New England, which already have seen close-calls from this cold snap.
Hartford's high of only 27 degrees on Monday was the second-coldest since 1905, according to The Weather Channel. Boston, meanwhile, hit a high of 28 — the third-coldest reading since 1872.
The Midwest, meanwhile, could get between 4 to 8 inches of snow Tuesday night — just as Wisconsin voters head to the polls for the state's primary, The Weather Channel reported.
"New England is done with the snow for this round, but new snow is coming in tonight to Michigan, northern Wisconsin and Minnesota," said Weather Channel Senior Meteorologist Kevin Roth.
Winter-weary Midwesterners won't get much respite before the end of the week.
Scattered rain and snow showers were expected to last into Thursday, according to the National Weather Service.
