Remember that "polar vortex" that hit the U.S. in January, the one that the Obama administration linked to climate change? Well, it might be back.

A blast of chilly air is expected to hit the northern and northeastern United States next week, during what is typically the peak of summer, The Washington Post reports.


According to the National Oceanic and Atmospheric Administration, a pool of cold air from Alaska's gulf will move to the Great Lakes region early next week and then slowly slide to the East Coast.

While the sweep of cold weather will take the edge off the summer sun, the cold snap won't compare to what was seen in January. Temperatures should be about 10 to 30 degrees below average for the month of July.

For parts in the Great Lakes and Upper Midwest, however, the temperature drop could be more severe, with highs in the 50s and 60s.

This weather behavior is definitely abnormal for the month of July.

Washington, D.C. will only get a taste of cooler temperatures, with lows in the 60s and 50s during the evening hours.

"Polar vortex" became a household term earlier this year as Republicans slammed the administration for its climate change policies, arguing global warming science should be called into question by the bitterly cold weather.

Research from Rutgers University and touted by White House science adviser John Holdren said the plunging temperatures could come from changes in the jet stream caused by climate change.
