Polar Vortex roars across the US

  • 56 reading now

A winter storm's unrelenting march across the United States' northern tier brought snow to a handful of states on Sunday and promised plunging temperatures that could drive frost as far south as Atlanta by week's end.

"It may not set records, but it will be really, really cold," Bruce Sullivan, senior meteorologist with the National Weather Service's Weather Prediction Centre said. "The thing is, it's not even winter yet."

Severe weather hits northern and midwest US

Parts of Iowa, Illinois, Indiana, Michigan Minnesota, South Dakota and Wisconsin were among states blasted Sunday by a band dumping up to 20 centimetres of snow more than a week before winter officially begins. A few areas, such as Granite Falls, Minnesota are reaching double-digit accumulations.

On Monday the snow was forecast to roll into Upstate New York and parts of New England. A wide swath of the region could see up to 15 centimetres, with more in the mountains. New York City was bracing for snow Sunday night that was expected to turn to rain by Monday, the National Weather Service said.

After that, it's time for an Arctic blast. Blame the Polar Vortex, similar to the one that rocked the US in January 2014, which is poised to drive demand for wool hats, mittens and leggings.

The Polar Vortex, lest we forget, is a massive area of high pressure and cold air that lingers around the North Pole. Sometimes it expands, allowing it to leak down over North America via the jet stream, the weather service explains.

The translation for North Dakota and Minnesota will be temperatures that in some areas fail to reach -17 degrees celsius -- for daytime highs.

In Washington DC, that means temperatures could fail to bounce above freezing on Thursday or Friday. Cleveland will rock a high of minus-eight degrees celsius on Thursday. Even Atlanta will see temperatures below freezing on Thursday night.

But before that, there is snow in the Midwest to contend with. Chicago had about 10 centimetres of snow early Sunday, with a few more forecast. But Chicago is Chicago, and snow is part of life. Charles Williams, Chicago Streets and Sanitation commissioner, was not intimidated by the storm.

"We anticipate a normal morning rush on Monday," Williams told the Chicago Tribune. "Everybody goes to work. No excuses to take off. The streets will be clear."
