IOWA — Below zero temperatures are expected to return across central Iowa Monday night into Tuesday morning, but the wind will make it dangerous to be outside. A Wind Chill Advisory is in effect Monday night through noon Tuesday for those between Hwy 34 (in southern Iowa) and Hwy 20 (in Northern Iowa). Temperatures will fall back into the lower teens at 6 p.m. and bottom out near -5° by sunrise Tuesday, but a northwest wind at 5-15 mph will make it feel like 20-30° below zero.

Parts of northern Iowa, including Kossuth, Humboldt, Wright, and Franklin county have been upgraded to a Wind Chill Warning. This is where wind chills will be -30° or colder.

Limit time outdoors

Time outdoors should be limited to less than 30 minutes for humans and animals as exposure to extreme cold can increase the chances of developing frostbite. Symptoms of frostbite include but are not limited to, numbness, a prickling feeling, and discoloration of skin. When outdoors, you should dress in several layers of loose clothing and make sure they stay dry. Wet clothing in extreme cold can increase the chances of developing hypothermia. Symptoms of hypothermia include but are not limited to, shivering, slurred speech, fatigue, and confusion.

What is a wind chill advisory?

Extreme cold headlines are issued by the National Weather Service. There are three types of wind chill alerts, and the distinction between the three can get confusing. A wind chill watch is issued in the 2-3 days leading up to a major cold snap. Once the expected cold gets within 1-2 days, an advisory or warning is issued. Deciding which to use depends on just how cold it will be. A wind chill advisory is issued for wind chills that will be UP TO -30°. Frostbite can develop on exposed skin in 20-30 minutes. In the most extreme cases or when wind chills will be at or below -30°, a wind chill warning is issued. This is when frostbite can develop on exposed skin in as little as 10 minutes.
