Strong northwest winds of 15 to 25mph with gusts to 30-mph will persist tonight into Sunday morning. Much of central and northern Iowa will have low temperatures below zero tonight. The combination of the blustery winds and cold temperatures will result in wind chill values of 20 to 30 below zero tonight into Sunday morning.
The National Weather Service has issued a wind chill advisory, which is in effect from midnight tonight to 10am Sunday. The coldest wind chill values will impact the area from late evening into late Sunday morning.
Northwest winds of 15 to 25-mph with gusts near 30-mph will be likely. Temperatures will drop to near zero by Sunday morning. Wind chill values of near 20 below zero will occur. Frostbite can occur within 30 minutes of exposed skin in these types of wind chill values.
A wind chill advisory means that very cold air and strong winds will combine to generate low wind chills. This will result in frost bite and lead to hypothermia if precautions are not taken. If you must venture outdoors, make sure you wear a hat and gloves.
