Bitterly cold temperatures and wind chill values well below zero have triggered a weekend wind chill advisory.
The advisory runs from 6 p.m. Saturday until 10 a.m. Sunday, according to the National Weather Service.
“Arctic high pressure brings in cold Canadian air to the region, along with blustery northwest winds,” the alert reads. “The combination of the very cold temperatures and gusty winds will generate bitterly cold wind chills in Southern Wisconsin.”
Wind chills could go as low as -30 in some areas.
