Snow will spread through southern Wisconsin again Sunday afternoon through Sunday evening, with an additional 1-2 inches of powdery, dry snow expected. Meanwhile, wind gusts of 35 to 40 MPH will result in blowing and drifting snow even after snowfall concludes.
Wind chill temperatures in the negative 20s are expected overnight Sunday into Monday night, which can lead to rapid onset of frostbite and hypothermia. With very gusty winds around 35 to 40 MPH, a few areas may see wind chills even lower than currently forecast. Bring pets indoors, cover all exposed skin, and check on elderly friends, neighbors, and relatives.
The most dangerous wind chills of negative 20 to negative 26 degrees are expected between 3 AM and 10 AM Monday, with continued cold and blustery conditions throughout the rest of the day.
