The long-range data shows we may be done with a true Arctic air mass similar to what we experienced in January. But we certainly aren't done with normal cold yet.

Research has found that rising temperatures in the Arctic are weakening weather systems that normally trap the cold around the poles, making winter weather more chaotic.

Ranked dead last, or perhaps not mentioned at all, would probably be the only state that sits partly within the Arctic Circle: Alaska. But 2025 is off to an interesting start as far as the weather is concerned.

It's like "bomb cyclone" or "firenado." It seems like the sort of phenomenon that would be responsible for the record-breaking blast of cold, snow and wintry conditions that reached all the way to the Gulf Coast this week.

A polar vortex dipping down from Siberia is bringing a cold front with frigid temperatures to millions Americans. See maps of the arctic blast.

The weather flow is gradually changing now and as we head into early February. Our storm systems will come from the west and southwest. One weather change that brings Michigan is a very up-and-down temperature pattern. If you look at the forecast of the upper-air flow over the next 15 days you will get the idea of a lot of changes in our weather.

With last week's freeze being the second time temperatures dipped below freezing this winter, many are wondering if this active winter pattern is setting the stage for an even colder February.

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

A disruption in the polar vortex is about to send an Arctic air mass from Siberia as far south as Florida. Yes, Siberia—and it’s as dramatic as it sounds. As many as 47 states will experience unseasonably cold temperatures. Some areas will be hit with dangerous wind chills as low as 40 below zero.

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 ...

Arctic air has brought chilling temperatures as low as 12 degrees in New York City on Monday night but are we in a polar vortex? A polar vortex settled its way over New York City and New Jersey following Sunday’s snow storm,
