Though this weekend may have suggested inklings of spring with areas from Washington, D.C., to Boston enjoying 50- to 60-degree temperatures, winter weather is taunting much of the nation with another deep freeze.

The polar vortex effects are making a comeback in the Midwest and Northeast this week, as some areas are expected to dive 40 degrees below average February temperatures, USA Today reported.

"Record cold temperatures are possible for the High Plains, Upper Midwest and Great Lakes later this week," the National Weather Service warned.

USA Today said that by Wednesday, areas around the Great Lakes will dip to single-digit temperatures, while temperatures in Tennessee will approach the freezing mark.

“This air mass that is coming down across the northern plains to northern New England is about as cold as it can get at this time of year,” AccuWeather meteorologist Tom Kines said, according to Bloomberg.com.

The Northeast is expected to endure a minor snowstorm that could leave as much as 3 inches of snow blanketing areas of the region, The Washington Post reports. The National Weather Service has issued a winter weather advisory from 1 a.m. to noon on Wednesday for the Washington, D.C., area. New York City and Philadelphia also may see minor accumulations of snow, The Weather Channel reported.

The snow flurries could bring flight delays and cancellations, AccuWeather reported.

The bitter cold temperatures are expected to hold up through the beginning of March and could lead to one or two more snowstorms, AccuWeather said.
