The start time for Denver's Marade honoring Martin Luther King Jr. on Monday, Jan. 20 has been delayed due to the forecasted dangerous cold temperatures.

The coldest temps in about a year are taking aim at Colorado as a major blast of Arctic air will plunge Denver below freezing, remaining there for several days as flash freezing becomes a concern. Here's a look at potentially dangerous wind chills expected in Colorado and the Denver metro area.

Skies will remain clear for Denver’s weather overnight awaiting a very mild day tomorrow. Look for an arctic blast to come in from the north starting this weekend.

An arctic front will sweep through Colorado Friday afternoon with dangerously cold air and accumulating snow lagging behind it.

Thursday will have mainly sunny skies and above-average highs before arctic air moves in for the weekend with snow on Saturday in the Denver weather forecast.
