DENVER — The coldest air from our current Arctic blast arrived in metro Denver Wednesday afternoon. And with it comes record-breaking dangerously cold temperatures.

The high Wednesday only got to 6 degrees, which set a for the lowest maximum temperature for the date. The old record was 9 degrees set on Nov. 12, 1916.

As the snow moves out and the skies clear, even colder temperatures will descend along the Front Range, with a low Thursday morning expected to be minus 12 degrees. But if the skies clear earlier, even colder temperatures are likely.

The snowy conditions and subzero wind chill prompted some schools to delay opening or to be closed entirely earlier in the day. The snow-packed and icy roads made for a slow-go on the metro-area roadways during the evening commute.

Just before 7 a.m., the temperature dropped to minus-1 at Denver International Airport, the first time it has officially been below zero in Denver since Feb. 7.

Deicing operations were in full effect at Denver International Airport, which created consistent delays of around an hour. Travelers headed to the East Coast might experience longer delays because of bad weather at their destinations.

As the snow moves out and the skies clear, even colder temperatures will descend along the Front Range, with a low Thursday morning expected to be minus 12 degrees. But if the skies clear earlier, even colder temperatures are likely.

Thursday will be warmer, relatively speaking, with a high of 18, and if the high temperature Thursday stays below 20 degrees, it would be the first time Denver would have three consecutive days below 20 degrees in November.

Denver International Airport recorded its first official snowfall of the 2014-15 season Tuesday. It marked the seventh-latest date of the first official snow in Denver recorded history.

The bitter cold snap looks like it will end Friday, with a high in the upper 30s. But another chance of snow moves into the area Saturday afternoon and night.

A Winter Storm Warning is in effect for the mountains, including Vail, Aspen and Crested Butte for Thursday afternoon into Saturday, with snow totals as high as 8 to 18 inches possible.
