If you’re making plans for Saturday evening, you’ll want to keep them indoors. We’re facing some of the most dangerous cold conditions of the winter season across southern Wisconsin, and this Arctic blast means business.

The First Alert Storm Team has designated today as a First Alert Day due to snow moving through parts of the area, followed by dangerously cold temperatures.

LAKE CHARLES, La. (KPLC) - A cold front will send us back to winter for a couple days, bringing a sharp drop in temperatures and a freeze on Monday morning.

They are expected to drop to 25 to 30 degrees below zero, making frostbite a major concern Sunday. 20 minutes is all it would take for frostbite to develop on any exposed skin, so make sure to cover as much skin as you can and wear multiple layers.
