Wind Chill Watch Issued for Several Counties Ahead of Bitter Blast Thursday

The watch warns that wind chills as low as 30 below-zero are possible

After a winter system brought more snow, ice and freezing rain to much of the Chicago area this week, dangerously cold temperatures are putting several counties under a Wind Chill Watch. 

The watch was issued for McHenry, Lake, DeKalb, Kane, LaSalle and Kendall counties beginning Thursday evening and continuing through Friday morning. 

It warns that wind chills as low as 30 below-zero are possible. 

"A Wind Chill Watch means there is potential for a combination of very cold air and the wind to create dangerously low wind chill values," the National Weather Service warned. 

The cold wind chills could cause frostbite on exposed skin in as little as 30 minutes, NWS said.
