Polar Vortex making a cold comeback

Don't get used to the warm weather. It'll freeze up again.

WDEL's Amy Cherry has more.

The Polar Vortex will be back.

"It's going to turn somewhat colder out toward the end of the weekend," says AccuWeather's Dr. Joe Sobel.

The mild air that's been sitting over much of the eastern half of the nation will be gone, and it will feel a lot more like winter.

"There are some signs for the second half of January and into the first couple weeks of February that we're going to get some real rallies from winter," he says.

He won't rule out some major snowstorms either.

This weekend's blast of arctic air won't be nearly as bitter nor will it bring record cold.
