A wind chill warning for McHenry County is set to go into effect from 7 p.m. Wednesday to noon Thursday as an arctic cold front will come through the area.
Temperatures are expected to drop to several degrees below 0 after the front goes through, the National Weather Service said.
Combined with gusty winds of 25 to 35 mph, wind chills are expected to reach 30 below overnight and 30 below on Thursday morning, according to the advisory.
Travel also can become difficult as fresh powdery snow will create areas of blowing and drifting snow on Thursday morning, the weather service said.
The weather service advised people to wear a hat and gloves when going outside.
