Rising Arctic temperatures and melting sea ice could be causing cold air to flow into the Northern Hemisphere. But not all scientists agree. By Eric Niiler The polar vortex is a ribbon of ...

As the Great Lakes region braces for a predicted near-record cold this weekend, Michiganians are again cursing the dreaded "polar vortex." But what exactly is this meteorological menace? And why is it ...

A potentially major snow storm this weekend could give way to a blast of Arctic air for the second consecutive week. The next polar vortex impact is expected to follow a storm that could dump 6 inches ...

A January thaw that brought widespread record warmth to the United States is coming to an end. It will be replaced by the familiar polar vortex pattern that caused below-average temperatures in the ...
