The coldest wind chills will extend from highway 20 and to the north. By Monday morning, this is where wind chills will be between -35°F and -45°F. By Tuesday morning wind chills will still be between -35°F and -45°F before gradually warming up.
From Des Moines and to the south, wind chills Monday morning will be between -35°F and -45°F. Monday night wind chills will be between -30°F and -40°F before gradually warming up to -25°F to -35° Tuesday morning.
When wind chills are this cold, it is possible to get frostbite in less than 10 minutes across northern Iowa, and between 10 to 30 minutes across southern Iowa. As of 4pm Friday afternoon, portions of northeast Iowa are under a wind chill warning due to these life-threatening wind chills, while most of the state is under a wind chill watch. This watch will be upgraded in the days to come to either a wind chill warning or a wind chill advisory. When that happens we will post the very latest watches and warnings to our Facebook page. Remember to bundle up as any exposed skin could become frost bitten, and remember to bring your pets in as well. Stay tuned to the Iowa Storm Chasing Network for the very latest.
