Zero Hedge
Submitted by Tyler Durden on 01/13/2014
Just when everyone thought the infamous polar vortex is gone (if not quite forgotten, having dipped the temperatures in some part of the US to sub-Martian levels), it’s baaaack. Sky News reports that America is set to be hit by another blast from the polar vortex although this time Niagara falls may not freeze, as temperatures are likely to be higher than last week’s extreme conditions. “The polar plunge is expected to move south from Canada, bringing colder air and sub-zero temperatures to the US this week. Forecasters say it will sweep over the lower Mississippi Valley and Midwest on Tuesday and Wednesday, and then hit the East on Thursday. The main thrust of the cold air will follow up a couple of days later.”
“Following the retreat of Arctic air this weekend, waves of progressively colder air will move southward over Canada this week,” said Paul Pastelok, AccuWeather.com’s lead long-range forecaster. “We will likely see a piece of the polar vortex break off and set up just north of the Great Lakes spanning January 16 to 20.
“This next main arctic blast will not rival, nor will be as extensive as the event last week.”
Many areas are still recovering from last week’s polar vortex, which saw the mercury plunge to -12C (11F) in New York City and -24C in Chicago.
A Coast Guard cutter was brought in to keep shipping lanes open, but the ice was too thick to break in places.
