Wisconsin – Cold air slices across open fields and city streets this morning, rattling signs and biting exposed skin within seconds. Sidewalks look quiet, but the danger feels immediate as wind drives temperatures sharply lower across northeast Wisconsin.
According to the National Weather Service in Green Bay, an Extreme Cold Warning takes effect overnight and lasts through Friday afternoon, with an Extreme Cold Watch extending into Saturday morning. Wind chills between 30 and 40 below zero are expected, creating life-threatening conditions with frostbite possible in as little as ten minutes.
Light snow and flurries may drift through at times today, briefly cutting visibility and creating slick patches. Roads across Brown, Oconto, Shawano, and Outagamie counties could turn icy fast as any daytime melting refreezes quickly. US-41, WI-29, and local roads may look clear but hide black ice, especially on bridges and ramps.
Actual temperatures remain well below zero through Friday, with daytime highs struggling to rise. Winds stay strong enough to keep wind chills dangerous even during daylight hours. Residents should limit time outdoors, cover all exposed skin, and keep pets inside. Drivers are urged to keep extra blankets, chargers, and fuel on hand in case of delays.
Cold lingers into Saturday before easing slightly Sunday. Snow chances return late in the weekend and into early next week, adding another layer of travel concern as the region remains locked in winter.
More advisories could be issued if winds increase or snow chances rise.
