When the Polar Vortex is in a weakened state, a jet stream wobble sending polar air into the mid-latitudes becomes more ...

Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around ...

One of the key players in these dramatic shifts is something called the polar vortex. The polar vortex is a massive area of cold air located high in the atmosphere, typically spinning over the ...

two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere. As the Arctic continues ...

It's a term you hear every couple of winters, when we get stuck in the coldest of cold patterns – polar vortex. But what exactly is it and how does it impact our weather? The polar vortex is ...

But is Wisconsin in a polar vortex? And what is a polar vortex anyways? Here's what to know. What is a polar vortex? A polar vortex is a low pressure area where air swirls counterclockwise keeping ...

At the same time we go into a touch milder southwest flow, the polar vortex will still be churning away over northeast Canada. I don’t expect a full onslaught of the polar vortex to shift south ...

You may have seen social media posts about it and chatter of big weather pattern changes heading our way, but what's really ...

A strong polar vortex in the stratosphere has brought subzero temperatures to the Midwest, Mid-Atlantic and deep into the South.

The polar vortex, a swirling mass of cold air located over the polar regions, is responsible for the cold. It's bringing extreme cold as far as the Deep South. Overnight lows will be well below ...
