Chicago is in the grip of an Arctic blast, bringing dangerously low temperatures, brutal wind chills, and icy conditions that could make stepping outside a serious health risk. As the Midwest endures this deep freeze, residents are urged to stay indoors, bundle up, and take precautions against hypothermia and frostbite.
With wind chills plunging as low as -30°F, exposed skin can suffer frostbite in just minutes. The city has activated warming centers for those in need, while officials warn of the dangers posed by prolonged exposure to the frigid air. If you must go outside, take extra precautions—this level of cold is not just uncomfortable, it’s dangerous.
Frigid Days Ahead: A Day-by-Day Breakdown
The National Weather Service has issued a Cold Weather Advisory for Chicago, warning that conditions will be extremely hazardous, especially in the morning and overnight hours.

- Thursday, February 20: Some sunshine returns, but it won’t do much to warm things up. The high will struggle to reach 19°F (-7°C), and another icy night follows with lows of 9°F (-13°C).
- Friday, February 21: A slight improvement with a high of 25°F (-4°C), but it will still feel brutally cold.

City Officials Activate Emergency Warming Centers
With temperatures dropping to life-threatening levels, Chicago officials have activated warming centers across the city to help residents without adequate heating.
- These centers are open Monday through Friday from 9 AM to 5 PM, with extended hours during severe cold.
- Residents in need of shelter can call 311 or visit the City of Chicago’s website for the nearest location.
- CTA buses will also provide warming options for the homeless, offering rides throughout the city to keep people out of the cold.
Officials stress that if you or someone you know is struggling to stay warm, seek shelter immediately. This is not a normal cold spell—it’s a dangerous weather event.

Why This Cold is So Dangerous
Chicago is no stranger to cold winters, but this Arctic blast is on another level. What makes this event particularly dangerous is:
- Extreme Wind Chills: The wind makes it feel much colder than the actual temperature. When wind chills hit -30°F or lower, frostbite can occur within 10 minutes.
- Prolonged Freezing Conditions: With multiple days below freezing, pipes can burst, roads can ice over, and heating systems will be under extreme strain.
- Health Risks: The risk of hypothermia and frostbite skyrockets. If you don’t have proper clothing, exposed skin can freeze in minutes.
How to Stay Safe During the Extreme Cold
1. Dress for the Conditions
If you must go outside:
- Layer up! Wear thermal layers, a windproof coat, gloves, a hat, and a scarf to cover exposed skin.
- Keep extremities warm. Frostbite hits fingers, toes, ears, and noses first.
- Limit your time outside. The less exposure, the safer you’ll be.
2. Protect Your Home and Pipes
- Let faucets drip overnight to prevent pipes from freezing.
- Open cabinet doors to allow warm air to circulate around plumbing.
- Check on heating systems and keep emergency supplies handy in case of power outages.
3. Avoid Dangerous Travel Conditions
- Roads will be slick and icy in the mornings. Take extra time if driving.
- Public transportation may experience delays—check schedules in advance.
- Avoid unnecessary travel! If you don’t need to go out, stay home.
4. Check on Vulnerable Neighbors and Family Members
- The elderly, young children, and those with medical conditions are at the highest risk.
- Make sure they have heat, food, and proper clothing.
When Will It Finally Warm Up?
The worst of the cold will last through Friday, February 21. By the weekend, temperatures will rise above freezing for the first time in days, providing some much-needed relief.
By Monday, February 24, highs will be in the 40s, a welcome change after a week of bitter cold. But until then, Chicago will remain locked in a deep freeze.
Final Thoughts: Stay Safe and Stay Warm, Chicago!
This is not a typical winter cold snap—this is an Arctic blast that could be deadly if precautions aren’t taken.
- Dress in layers, stay indoors as much as possible, and check on those who may need help.
- Use heating devices safely—no gas stoves, no space heaters near flammable materials.
- Keep an eye on the forecast, and don’t underestimate the cold.
