If you thought the weather was bad here, be grateful you're not in any of the eastern half of the US this week, as a 'polar vortex' brings temperatures as low as -36°C to parts of the country. Yes, minus 36. And daily highs of only -20°C in some parts, with forecasts saying it may go as low as minus 51 degrees Celsius.

Apart from the lethal chill factor, the insane weather is also causing travel chaos as those unfamiliar with icy conditions suddenly encounter the worst of it on the roads. Case in point, this 25 car pileup on a highway started by one idiot.

Chilling stuff. Pun intended. Here's hoping no one was seriously injured. (Some understandably NSFW language out of the watcher/recorder below)
