- Extreme cold arrives: Gusty winds will drive wind chills well below zero, creating a real risk of frostbite and hypothermia in minutes.
- Outages raise the stakes: Any power loss during the cold could cause indoor temperatures to drop quickly, increasing danger for people and pets.
- Preparation matters: Limit outdoor exposure, protect pets and pipes, and have backup heat and emergency supplies ready.
Wisconsin is no stranger to bitter cold, but the Arctic air spilling into the Upper Midwest this weekend is on a different level — and it comes with a serious warning. When extreme cold combines with potential power outages, conditions can quickly turn from uncomfortable to dangerous.
According to the Weather Prediction Center, dangerously cold air is expanding across the Northern Plains and Great Lakes, accompanied by gusty winds that will drive wind chills to hazardous levels. For Wisconsin, the bigger concern may not be snowfall totals — it’s what happens if the power goes out while temperatures plunge.
Cold That Can Hurt in Minutes
Wind chills across parts of the Upper Midwest are expected to fall well below zero, creating a real risk of frostbite and hypothermia. Even brief exposure can become dangerous when winds are strong.
“This arctic blast will be accompanied by gusty winds, leading to dangerous wind chills.”
The cold air is also exceptionally dry, which accelerates heat loss from exposed skin. In these conditions, frostbite can occur in as little as 10 to 30 minutes, especially on fingers, toes, ears, and faces.
While Wisconsinites are accustomed to cold weather, wind chills this extreme demand extra caution — particularly for children, older adults, outdoor workers, and anyone without reliable heat.
When the Power Goes Out, the Risk Rises Fast
The Weather Prediction Center also warns that power outages could significantly increase the danger during this cold snap. Heavy snow and ice from a major winter storm farther south could strain energy systems across the region, and any loss of electricity in extreme cold becomes a serious emergency.
“Any power outages caused by the impending major winter storm could prolong and compound this risk.”
Without heat, indoor temperatures can fall rapidly. In sub-zero conditions, homes can cool to unsafe levels within hours, especially in older buildings or poorly insulated spaces. Frozen pipes, loss of running water, and limited communication only add to the challenge.
Pets, Pipes, and People All at Risk
Extreme cold doesn’t just affect people outdoors. Pets can suffer frostbite and hypothermia quickly if left outside, even for short periods.
“Ensure pets and animals have protection from the cold.”
Inside homes, plumbing is vulnerable. Pipes running through exterior walls, crawl spaces, and garages can freeze and burst when temperatures drop sharply — especially during prolonged cold or power loss.
Preparation Matters — Even Now
While this Arctic blast is already underway, there’s still time to reduce risk:
- Limit time outdoors and cover exposed skin.
- Bring pets indoors and ensure livestock have wind protection.
- Check backup heat sources and carbon monoxide detectors.
- Let faucets drip slightly to reduce pipe-freeze risk.
- Keep extra blankets, flashlights, and charged devices ready.
Extreme cold warnings and advisories are in effect across much of the Upper Midwest, underscoring the seriousness of this event.
“These wind chills will pose life-threatening risk of hypothermia and frostbite to exposed skin.”
The Bottom Line
This isn’t just another cold snap. The combination of Arctic air, strong winds, and the potential for power disruptions creates a high-risk situation across Wisconsin. Staying warm, staying informed, and planning for contingencies could make all the difference as the cold tightens its grip.
