Get ready to shiver.
Some of the coldest air of the season is poised to barrel into portions of the central and eastern U.S. over the next couple of days, forecasters say.
"Very cold Arctic air will plunge southward into the northern and central Plains through Monday and into the Great Lakes and Midwest Monday and Tuesday," AccuWeather senior meteorologist Jack Boston said.
Some locations from the eastern Dakotas to Minnesota and northern Wisconsin will remain below zero degrees for a period of 24-48 hours from Monday night into Wednesday night, according to AccuWeather.
Howling winds will drop the wind chill to a numbing 25 degrees below zero in some parts of the northern Plains, the National Weather Service said.
The cold will then plow east from Tuesday into Thursday, sending temperatures plummeting by some 30 degrees. For instance, after a high in the lower 60s Tuesday, New York City could struggle to reach freezing by Thursday, the Weather Channel said.
Highs in the 40s and lower 50s will be common in much of the South by Tuesday and Wednesday.
Along with the cold, snow will also fly across portions of the Midwest, Great Lakes and Northeast. Even portions of the South could see some snow.
In fact, wet snow is likely along an approximately 1,000-mile corridor from Tennessee to Maine spanning Tuesday night to Wednesday morning, AccuWeather said.
"Along the 1,000-mile swath, a general coating to 3 inches of snow is forecast," said AccuWeather meteorologist Bernie Rayno. "Much less snow is expected to accumulate on the roads," he added.
Still, by Wednesday morning, snow may create slick roads from Washington, D.C., and Baltimore to Philadelphia, New York City and Boston.
Lake-effect snow will be the story near the Great Lakes, where portions of Michigan, Ohio, Pennsylvania and New York State will see heavy snow at times. "We expect this to be the most substantial lake-effect snow event of the season so far throughout the Great Lakes region," AccuWeather Broadcast Meteorologist Laura Velasquez said.
