If you’re stepping outside today in Chicago, that number on your phone—18°F—is a total lie. Honestly, it’s one of those classic January days where the "official" temperature is basically just a suggestion while the wind does the real heavy lifting.
The actual temperature at chicago today is sitting at a steady 18°F, but thanks to some aggressive 17 mph gusts coming out of the southwest, it feels like 3°F. That’s the kind of difference that turns a quick walk to the coffee shop into a survival mission.
The Reality of Chicago’s Current Deep Freeze
It’s mostly cloudy out there right now, and if you look up, you’ll see that typical gray, heavy sky that usually precedes a dusting. We’re already seeing light snow in parts of the city. The high for the day isn’t going anywhere past that 18-degree mark, so what you see right now is pretty much the peak.
Humidity is hanging around 54%, which is actually somewhat dry for a snowy day, but that southwest wind is the real story. When the wind hits 17 mph at these temperatures, it strips the heat right off your skin. It’s the reason the Chicago Office of Emergency Management and Communications (OEMC) keeps their warming centers on standby.

What’s Happening with the Snow?
Don't expect a massive blizzard, but don't expect a dry commute either. There is about a 20% chance of light snow continuing through the afternoon and into the evening. It's that fine, powdery stuff that doesn't look like much until it's covering the black ice on the Kennedy Expressway.
- Current Temp: 18°F
- RealFeel: 3°F
- Wind Speed: 17 mph (Southwest)
- Sky Condition: Mostly Cloudy / Light Snow
Why January 17th is Historically Brutal
Chicagoans like to brag about their resilience, and looking at the records for January 17th, you can see why. While we are shivering at 18 degrees today, it could be way worse. Back in 1982, the city hit a record low of -23°F on this exact date. Imagine a wind chill on top of that.
On the flip side, there was one weirdly beautiful day in 1894 where it hit 60°F. But that's the anomaly. Usually, we're fighting for every degree above zero.

The "feels like" factor isn't just a marketing term for meteorologists. It’s a calculation of heat loss. At 3°F, frostbite starts becoming a genuine concern for exposed skin if you’re out for more than 30 minutes. If you’ve got a dog, keep the walks short. If they’re paws are lifting or they’re shivering, it’s time to head back to the radiator.
Looking Ahead to Tonight
As we move into the evening, the temperature at chicago today is expected to dip down to a low of 13°F. The clouds aren't going anywhere, staying thick and "mostly cloudy" through the night. The wind might shift slightly, but that southwest bite will remain the dominant feature of the local climate.
Surviving the 3-Degree RealFeel
Honestly, layering is the only way to handle this. You’ve probably heard it a thousand times, but a base layer that wicks moisture is vital because even in 18-degree weather, you can sweat if you're walking fast, and damp skin in 3-degree wind chill is a recipe for disaster.

The light snow is expected to taper off into just "cloudy" conditions tonight, but the moisture in the air will likely keep the roads "greasy."
Quick Checklist for the Afternoon:
- Cover the face: That 17 mph wind is looking for any gap in your scarf.
- Check the tires: Cold air makes tire pressure drop; if your "low pressure" light came on this morning, it's not a glitch.
- Watch the ice: Light snow on top of 18-degree pavement creates a very specific kind of slickness that salt struggles to melt instantly.
The temperature at chicago today is a reminder that winter in the 312 isn't about the number on the thermometer; it's about the wind off the plains and how well you've tucked in your shirt. Keep an eye on those southwest gusts—they aren't letting up until at least tomorrow morning.
Stay warm, keep the layers thick, and maybe just order the groceries in tonight.
Actionable Insights for Chicagoans Today:
- Seal the Gaps: Check your south and west-facing windows for drafts; with 17 mph winds, a small gap can drop a room's temperature by 5 degrees in an hour.
- Vehicle Prep: Ensure your windshield washer fluid is rated for sub-zero temps, as the light snow and road salt will create a film on your glass that freezes instantly.
- Pet Safety: Limit outdoor activity for pets to 10-15 minute intervals while the wind chill remains in the single digits.
