Hey Cook County, winter is about to pack a serious punch. A polar vortex is heading straight for us, promising dangerously low temperatures and bitter winds that will make even a quick trip outside feel brutal. Now’s the time to prepare and make sure you and your loved ones are ready for the extreme cold.

What’s in the Forecast?
Here’s a look at what’s ahead for the week:
- Thursday: A relatively mild day with breezy conditions and a mix of sun and clouds. Highs will reach 36°F, and lows will dip to 24°F. It’s a good day to get things done before the real cold arrives.
- Friday: The winds pick up, but we’ll still have some sun. Highs will be around 41°F, with nighttime lows dropping again to 24°F.
- Saturday: The Arctic chill begins to take over. Highs will barely reach 28°F, and lows will fall to 7°F. Expect cloudy skies and possibly a few flurries.
- Sunday: This is when the extreme cold sets in. Daytime temperatures will only get up to 11°F, and the low will plummet to -3°F. Breezy conditions will make it feel even colder, so be careful if you’re outside.
- Monday: Bitter cold continues with highs near 15°F and lows dropping to -6°F. Frostbite risks will be high, so bundle up if you need to go outside.
- Tuesday: The sun returns, but it won’t bring much warmth. Highs will hover around 11°F, with lows near 2°F.
- Wednesday: Temperatures start to ease up slightly, with highs reaching 28°F and lows at 21°F.
Why This Cold Is a Big Deal
This isn’t your average winter chill—this kind of cold can be dangerous if you’re not careful. Frostbite can happen in just minutes if your skin is exposed, and hypothermia is a real risk for anyone spending too much time outside without proper clothing. Roads and sidewalks will likely be icy, so even getting around safely could be a challenge.
How to Stay Safe During the Freeze
- Dress Warmly: Don’t leave the house without your warmest coat, gloves, hat, and scarf. Cover as much skin as possible to avoid frostbite. Thick socks and boots are a must to keep your feet warm and dry.
- Stay Indoors: The best way to avoid the cold is to stay inside. If you have to go out, make it quick and dress in layers.
- Prep Your Home: Double-check your heating system and make sure it’s working properly. Insulate exposed pipes to prevent them from freezing, and stock up on groceries, water, and extra blankets.
- Drive Carefully: If you need to travel, be cautious. Icy roads will make driving tricky, so slow down and leave extra space between your car and others. Avoid unnecessary trips if possible.
- Check on Neighbors: Cold weather can be especially hard on older adults or those who live alone. A quick visit or call can ensure they’re safe and have everything they need.
What to Do Now
Cook County, this Arctic blast isn’t going to last forever, but it’s going to be a tough few days. Use the time before the cold sets in to get ready—whether that’s restocking your pantry, testing your heater, or making sure you have warm clothes and supplies handy.

We’ve been through tough winters before, and we’ll get through this one too. Stay safe, stay warm, and don’t forget to check on your neighbors. Spring might feel far away, but this cold snap will pass soon enough!
