Another blast of Arctic air will keep high temperatures in metro Denver just above zero degrees on Monday and push wind chill readings to dangerously low levels. Light snow is falling in the region with showers expected to last until early afternoon.

A wind chill warning is in effect until 11 a.m. on Tuesday, with wind chill values expected to drop to 20 to 25 degrees below zero across most of northeastern Colorado on Monday. Wind chills could reach as low as 30 to 40 degrees below zero along the Colorado-Wyoming border, the National Weather Service in Boulder warned Monday morning.

The high temperature on Monday is forecast to reach only 2 degrees, and wind were blowing from the north at 13 miles per hour as of 7 a.m.

A winter storm warning is in effect until 5 p.m. Monday, with the greatest chance of snow along the northern Front Range expected before 11 a.m. Accumulations of one to two inches or more are likely before skies clear up this evening and temperatures drop to 9 degrees below zero.

The Douglas County Sheriff’s office warned residents on X to stay inside if at all possible and that those who do go out should bundle up and take an emergency supply kit.

Travel conditions are expected to be especially hazardous along mountain passes as light to moderate snow accumulations combine with wind gusts reaching up to 55 miles per hour, the National Weather Service warned.

Temperatures in the high country are expected to be higher than along the Front Range, due to the cold air mass settling in at lower elevations. High temperatures in Vail and Frisco are expected to be 10 to 12 degrees higher than those seen in Denver on Monday.

Relief is expected Tuesday, with mostly sunny skies and a high in Denver of 35 degrees and a low of 17 degrees.  The warming trend will continue on Wednesday, when the high is forecast to reach a balmy 49 degrees.
