DENVER — Bundle up, Colorado! Subzero temperatures, wind and snow are headed for Denver this weekend, according to the National Weather Service.

Light snow was already falling in northern Colorado’s mountains on Tuesday morning, NWS forecasters said. That snow is expected to make its way into Denver and across the Eastern Plains on Friday, signaling the start of a freezing weekend.

“An arctic airmass will bring bitterly cold air to Colorado beginning Saturday and lasting through Monday night,” NWS forecasters said in a Hazardous Weather Alert.

Forecasters said that most of northern and central Colorado will see temperatures below zero degrees over the weekend.

Overnight lows are expected to reach minus 15 to minus 20 across metro Denver, the Interstate 25 Corridor and the Eastern Plains, forecasters said in the outlook. Windchill could make it feel like 30 degrees below zero.

The coldest day forecast for Denver this weekend is Sunday. Temperatures will peak around 6 degrees and drop past minus 10 overnight into Martin Luther King Jr. Day.

In areas south of Denver, including Parker and Castle Rock, weekend temperature lows are expected to bottom out closer to minus 15, according to NWS forecasters.

Light, sporadic snow will continue in the Denver area through Sunday, forecasters said. How much snow will fall is still unclear, but NWS forecasters said there is potential for several inches of dry, fluffy snow.

The coldest temperatures will hit northern Colorado, especially near Kremmling and Waldon, forecasters said. Those cities can expect to see temperatures near minus 15 and 17 multiple days this weekend.

Denver and the rest of the state will gradually warm back up starting Tuesday, with temperature highs expected to hover in the low 30s, forecasters said.
