‘Brutal’ Arctic blast expected to bring frigid temperatures to North America

Extreme cold warning issued in Canada as US forecasters warn of wind chills in Texas and major snow in midwest and east coast

A “bitter” blast of cold Arctic air is set to bring dangerously frigid temperatures to swaths of North America, forecasters have warned.
