After a mild Thursday, an arctic blast of extreme cold will arrive in parts of Colorado on Friday afternoon. According to Pinpoint Weather Meteorologist Alden German, snow chances could start to affect the Friday evening commute and the below-freezing temperatures are expected to last for several days in a row.

Traffic is expected to be impacted along major highways, with northern Colorado towns even more likely to experience bitter cold conditions.

The long-talked-about deep freeze arrives Friday as Denver's weather makes a dramatic change through the weekend.
