Chicago Weather: Expect Wind Chills 20 Below

It’s bitter outside, and the cold snap is expected to continue throughout the week. Wind chill values are forecasted to be negative 17-degrees on Tuesday morning, Jan. 22. Winds are expected to be blowing west at 10 to 15 mph, with gusts as high as 20 mph, according to the National Weather Forecast (NWS).

There is some good news, however, it is expected to be sunny.

Tuesday night should warm up with mostly cloudy weather and wind chill values as low as negative 7-degrees.  

The NWS announced a hazardous weather outlook and wind chill advisory for Cook and Lake counties, and other areas in North Central and Northwest Illinois and Northwest Indiana on Monday.

Very cold air and strong winds will combine and produce low wind chills, the NWS stated, and the wind chill advisory continues through today as temperatures are expected to drop below zero.

The freezing temperatures can cause frostbite and hypothermia if precautions are not taken, the National Weather Service stated.

Tips to Dress Warm During Cold Weather, Recommended by The National Weather Service:

• Wear layers of loose-fitting, lightweight, warm clothing. Air trapped between the layers will insulate the body. Outer clothing should be tightly woven, water repellent and hooded.
• Wear a hat; 40 percent of body heat can be lost from the head.
• Cover the mouth to protect lungs from extreme cold.
• Mittens, snug at the wrist, are warmer than gloves.
• Try to stay dry and avoid the wind.
