Anytime we get an Arctic air blast down this far south, this is an artifact of the polar vortex rearing its ugly head,” said climatologist Barry Keim .

The cold temperatures are coming from a not uncommon expansion in the Polar Vortex, which are counter-clockwise rotating air currents that typically hang over the Arctic.

A once-in-a-generation snowstorm, tied to the polar vortex event across the Lower 48 states, was plastering the Gulf Coast with record-setting snow and ice on Tuesday.Why it matters: This region isn't equipped to cope with heavy snow,

Snow totals were rivalling all-time records. Officials were urging residents to take precautions and stay off roads.

A mass of air called the polar vortex has escaped the Arctic and plunged southward. Some scientists see the fingerprints of climate change.

A historic winter storm is poised to produce potentially record-breaking snows from coastal Texas to northern Florida late Monday into Tuesday. The event comes as an Arctic blast affects more than half the U.

The first-ever blizzard warnings were issued near the Texas-Louisiana border Tuesday as Winter Storm Enzo blew through, bringing an estimated five inches of snow to areas in Alabama, Mississippi, Louisiana and Texas.

A winter storm sweeping through the U.S. South on Tuesday was dumping snow at levels millions of residents haven’t seen before.

A rare winter storm has turned the South into an unlikely winter wonderland this week, giving cities like New Orleans more snow in a day than Salt Lake City has received all season.

A winter storm that is expected to begin in Texas next week could end up bringing snow and ice to parts of Florida, but the forecast is far from a lock.

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.

New Orleans went from almost 70 degrees to a record snowstorm within four days. In a few months, hurricane season will start, bringing a new trend of rapidly intensifying storms. Why it matters: The weather whiplash,
