An Extreme Cold Warning goes into effect overnight for all of Southeast Wisconsin. Wind chills will drop to 30-35° below zero. Frostbite can occur in as little as 10 minutes in these conditions. Limit your outdoor exposure, wear layers when heading out, and take extra precautions with your pets.

The coldest air we have seen during this arctic blast arrives overnight. Low temperatures will fall to around -10°. With breezy winds continuing, wind chills will be in the 30s BELOW zero overnight into early Tuesday.

Tuesday morning will be extremely cold, with Tuesday afternoon temperatures only recovering into the low single digits. Wind chills will remain in the teens and 20s below zero during the daytime hours. The skies will be mostly sunny.

The start of a slow warm-up will happen throughout the day on Wednesday as highs push back into the 20s and wind chills finally go positive. Wednesday also brings more cloud cover and some light snow, anywhere from a dusting to an inch looks likely. Depending on the timing of the snow, roads could be slippery on Wednesday morning and afternoon.

Temperatures will get back near normal heading into the weekend.
