>> Winter in much of the northern half to take a severe turn next week as forecasters are predicting frigid weather similar to the life threatening lows of 2014's polar vortex when temperatures dropped to as much as 60 below 0, killing at least 9 people in the US. The coldest weather expected to hit the Midwest and Northeast starting Tuesday.
AccuWeather warning temps in the Minneapolis, St. Paul area could drop to single digits. Chicago will be relatively balmy by comparison with expected temperatures in the teens. A polar vortex is a cold air mass that generally hovers over the poles, as its name suggest, but can shoot over the US thanks to a jet stream.
The big chill comes after the warmest ever October through November period. Current weather patterns suggest a potential follow up blast will arrive the week before Christmas, which may be even worse the next week's dreaded deep freeze.
