Weather in January is a fickle beast. One minute you're walking to the train in a light jacket, and the next, you're dodging a literal wall of snow that appeared out of thin air. Honestly, that’s basically what happened this past Wednesday, January 14, 2026. If you were looking at your phone thinking, "Wait, what was the temperature on Wednesday anyway?" you aren't alone. The day started with a strange, eerie warmth in some places and ended with a brutal Arctic slap.
It wasn't just "cold." It was the kind of cold that feels personal.
The Tale of Two Wednesdays
In the morning, things were actually looking up for a lot of people. If you were in New York or Atlanta, you might have been tricked into a false sense of security. New York was hovering around 51°F during the afternoon. That’s not exactly tropical, but for mid-January in the Northeast? You've gotta take those wins when you can. Atlanta was a bit more somber, sitting in the low 50s with some annoying rain showers, making it feel way colder than the thermometer suggested.

But the real story was in the Midwest.
While the East Coast was coasting on mild air, Chicago was getting hit by what meteorologists call a "snow squall." It sounds fancy, but it basically means a localized, intense blizzard that hits like a freight train. Around 7:23 AM at Midway Airport, visibility dropped to a quarter-mile. Winds were gusting at 47 mph. The temperature didn't just drift down; it fell off a cliff.

According to National Weather Service reports, temps dropped 5 to 8 degrees in just 30 minutes. One minute it's a chilly morning; the next, you're in a flash-freeze situation.
Breaking Down the Numbers
The contrast across the country was wild. You had folks in Billings, Montana, soaking up low 60s and sunshine. Meanwhile, Denver was sitting pretty at 57°F. It’s kind of weird to think that Denver was warmer than Atlanta on a Wednesday in January, but that’s the 2026 winter for you.
- New York, NY: Topped out at 51°F before the cold front moved in.
- Chicago, IL: Started in the teens and stayed there, with a bitter 16°F reported at Midway.
- Detroit, MI: Started in the upper 30s but plummeted into the 20s by the afternoon.
- St. Louis, MO: The city had to activate "Code Blue" shelter protocols because the overnight low was expected to hit 20°F.
Why the Snow Squalls Mattered
Most people get weather wrong because they only look at the "High" and the "Low." But the rate of change is what actually ruins your day. In Detroit, the warm morning air met a sharp Arctic front. This created a mess. Light rain turned into drizzle, which then froze as the temperature dipped below 32°F. By the time the snow "blossomed" (that's the NWS's poetic way of saying it started dumping snow), it was landing on a sheet of ice.
That’s why the PM commute in Detroit was a disaster. There were 296 flight delays at Metro Airport alone.

The Impact on Your Wallet and Plans
When the temperature on Wednesday behaved like a roller coaster, it wasn't just about whether you needed a scarf. In St. Louis, the city had to scramble to open 350 emergency shelter beds. When the temperature hits that 20°F mark, it becomes a public health crisis.
If you were trying to travel, you were basically out of luck if your route went through the Great Lakes. The "lake effect" snow picked up about 20 inches in parts of Michigan and Indiana. That isn't just a dusting; that's "stay home and pray the power stays on" weather.
What to do next time the forecast looks this "swingy"
- Check the "Feels Like" index: The raw temperature on Wednesday didn't tell the whole story; the 50 mph wind gusts made 20°F feel like sub-zero.
- Watch for Snow Squall Warnings: These are like tornado warnings for winter. If your phone buzzed on Wednesday morning, it was for a good reason.
- Salt early, not late: In places like Detroit, the rain-to-snow transition meant ice was trapped under the powder. If you didn't salt while it was still raining, you were walking on a skating rink.
Keep an eye on the "frontal boundaries." When you see a high of 50°F and a low of 20°F on the same day, you aren't looking at a "nice day." You're looking at a weather event.
