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.

It is January in Denver and the National Western Stock Show is in town, which can only mean one thing ... cold and snowy Colorado weather is around the corner. It is a tradition at this point, and this year will be no different. An arctic blast will bring temperatures 20 to 40 degrees below average and a chance for snow.

Denver’s cold weather shelters will be open for another week as frigid weather makes its way across the state.

Skies stay clear Tuesday night with light winds. Overnight lows will be close to seasonal averages, dipping into the upper teens. FOX31 Pinpoint Weather Chief Meteorologist Dave Fraser is tracking extreme cold across the area this weekend.

The City of Denver is extending its severe weather shelter activation into next week. Denver's Department of Housing Stability activated its Cold Weather Shelter plan on Dec. 30 and has extended it until at least 11 a.m. Tuesday, Jan. 21.
