The National Weather Service has put Yellowstone County under a wind chill advisory until noon Monday.  Wind chill values could get to around minus 35 degrees in Billings. The advisory includes areas west to Livingston and east to the state border.

The National Weather Service says wind chills will become the main concern through mid-week. It says conditions will be the worst in north central Montana where wind chill values could approach 55 degrees below zero at times. Remember, dangerously cold wind chills could cause frostbite on exposed skin in as little as 10 minutes.
