Chicago is facing one of its coldest days in recent history as a powerful Arctic blast sends temperatures plunging to dangerous levels. Weather experts are warning that the extreme cold could cause frostbite in under 10 minutes, making this a life-threatening situation for anyone caught outside unprepared.
The National Weather Service has issued an Extreme Cold Warning, with wind chills expected to reach -25°F (-32°C) or lower across the city. This means that stepping outside without proper protection could result in severe injuries or even death from exposure.

The Immediate Dangers: Frostbite & Hypothermia
- Frostbite: When temperatures are this low, any exposed skin can freeze in minutes. Early symptoms include redness, numbness, and a burning or tingling sensation. If untreated, frostbite can lead to permanent damage, including amputation in severe cases. If you notice any of these symptoms, seek shelter immediately and warm the affected areas.
- Hypothermia: This occurs when the body loses heat faster than it can produce it, leading to a dangerous drop in core temperature. Symptoms include shivering, confusion, drowsiness, and slurred speech. If someone shows these signs, call for medical help immediately and move them to a warm location.
How to Stay Safe in This Brutal Cold
Chicagoans are being urged to take extreme precautions as these freezing temperatures settle in. If you don’t have to go outside, don’t. If you must step out, here’s how to protect yourself:
- Dress in layers – Wear multiple layers of loose-fitting, insulated clothing. Cover all exposed skin, especially your face, hands, and ears, which are most vulnerable to frostbite.
- Limit time outdoors – If you must be outside, keep it brief. Stay indoors as much as possible until the cold snap passes.
- Use warming centers – The city has opened multiple warming centers, including public libraries and shelters, to help residents stay warm. Check for locations near you if your home is not warm enough.
- Keep your home safe – To prevent pipes from freezing and bursting, leave faucets dripping slightly and keep indoor temperatures stable. Check on elderly neighbors and those with limited mobility to make sure they are safe and warm.
When Will the Cold Ease?
The good news? Relief is coming. While temperatures will remain dangerously cold for the next 24-48 hours, meteorologists predict that by the weekend, Chicago will see a slight warming trend, with temperatures rising into the upper 20s and 30s.
