Environment and Climate Change Canada issued an extreme cold warning around 4 a.m. Friday.
“Today will be another cold day with temperatures well below seasonal and similar to what we’ve been experiencing all week long,” said Tiffany Lizée, Global News Calgary’s chief meteorologist.for iPhone, iPad and Android. So what’s causing this spate of frigid air? Lizée attributes it to a polar vortex, which is an area of low pressure over the poles, and a trough in the jet stream that has been pushing cold arctic air down into Western Canada.
