Don't let that sunshine fool you. Despite the bright skies, dangerous temperatures and wind chills will occur again tonight, Monday, Feb. 8, according to the National Weather Service in Duluth.

Bitterly cold temperatures will continue through the week with a wind chill advisory remaining in effect for Cass and Crow Wing counties through noon Tuesday, Feb. 9, when the advisory may be extended, the weather service said.

The weather service called the wind chills dangerous and life-threatening.

"Coldest wind chills remain on track. There is high confidence in dangerously cold wind chills across northern Minnesota (Monday) morning and tonight/Tuesday morning," the weather service said in an emailed weather update. "Wind Chill Warnings across far northern Minnesota will continue through Tuesday morning though temperatures may briefly rise above -40 during the afternoon in those areas. Wind Chill Warnings/Advisories may need to be extended through much of the week, at least for portions of the Northland. "

Wind chills reached 32 degrees below zero and 33 degrees below zero Monday morning, Feb. 8, in Cass and Crow Wing counties. At these values, it can take less than 10 minute for frostbite to develop on exposed skin.

Predicted wind chills overnight Monday, Feb. 8, into Tuesday, Feb. 9, are 36 degrees below in Walker and 29 below in Brainerd.

Wind chills were 48 degrees below zero in International Falls, 42 below in Virginia, 39 below in Ely and 41 below in Grand Marais on Monday morning.

The weather service offers the following wind chill safety tips:

  • Minimize exposure: Avoid exposure during the coldest wind chills.
  • Stay dry: Wet clothing causes body heat to be lost faster. Wear waterproof insulated boots.
  • Stay covered: Wear a hat and gloves. At least half your body heat is lost if your head is not covered.
  • Dress in layers: Trapped air between layers helps to insulate.

Wind chill is how the wind and cold feel on exposed skin. Wind and cold combined carry heat away from the body, which can cause frostbite and/or hypothermia.

A Wind Chill Warning is issued when dangerous, life-threatening wind chills are likely (40 degrees below zero or below). Frostbite can occur in 10 minutes or less. Take action to protect yourself from the cold.

A Wind Chill Advisory means the combination of cold air and wind will create very cold wind chills (25 below zero to 40 below zero), which could be dangerous without appropriate preparation. Frostbite can occur in 15-30 minutes. Use caution.

The weather service offers winter weather preparedness tips:

  • Winterize your car, and be sure to include a winter driving safety kit.
  • Restock your emergency kit at home with batteries, food, water, etc.
  • If you have a generator, make sure it is working. Never run a generator in an enclosed space like a garage.
