The National Weather Service in Duluth issued a wind chill advisory from midnight to 9 a.m. Tuesday for northern Aitkin, Cass and Crow Wing counties.
In Brainerd, the low temperatures late Monday and early Tuesday was expected to be 8 degrees below zero to 13 degrees below zero, which combined with north winds of 5 to 10 mph could create wind chills of 20 to 30 degrees below zero.
A wind chill advisory means a combination of bitterly cold Arctic air and brisk winds will create dangerously cold wind chill values. Exposed flesh can freeze in 15 to 25 minutes with wind chill values of 25 degrees below zero to 40 degrees below zero, resulting in frost bite and possibly hypothermia.
On Tuesday, the weather service’s forecast calls for partly sunny skies and high temperatures of 7 to 12 degrees, north winds of 10 to 15 mph and wind chills of 20 to 30 degrees below zero.
Tuesday night low temps of 15 to 20 degrees below zero are expected with wind chills of 30 to 40 degrees below zero. While lows Wednesday night aren’t expected to be as severe — 2 degrees below to 7 degrees below — wind chills of 30 to 40 degrees below are still expected.
If the weather service’s forecast holds, things should turn around Thursday, with partly sunny skied and high temps of 18 to 23 degrees possible.
