If you’ve stepped outside lately and felt like the air was trying to bite your face off, you’re not alone. Honestly, the weather last seven days has been a total chaotic mess. We started the second week of January 2026 with some weirdly mild air, only for the atmosphere to basically pull the rug out from under us.
It wasn't just "winter being winter." We actually saw a legitimate atmospheric breakdown.
Experts at the National Weather Service (NWS) and various European monitoring agencies had been eyeing a Sudden Stratospheric Warming event. That sounds like a boring science term, but what it actually means is the "fence" holding the cold Arctic air at the North Pole broke. Once that fence falls, the cold air spills south like a knocked-over bucket of ice water.

The Mid-Week "Flash Freeze" and Snow Squalls
The real drama hit around Wednesday, January 14.
In the Midwest, specifically around Chicago and the Great Lakes, things went from "kinda chilly" to "I can’t see the hood of my car" in about ten minutes. The NWS Chicago office issued multiple Snow Squall Warnings. These aren't your typical winter storms. They're more like winter tornadoes—intense, blinding bursts of snow paired with 50 mph wind gusts.
Visibility at O'Hare Airport dropped to near zero.
I talked to a few people who were caught on I-57 during the squall, and they said the "flash freeze" was the scariest part. The roads went from wet to sheer ice before the salt trucks could even get out of the garage. Temperatures in places like Sioux City and Des Moines plummeted nearly 10 degrees in less than an hour.
Why the West is Actually Worried
While the East was freezing, the West was dealing with a different kind of "weather last seven days" nightmare: a massive snow drought.
Check this out—as of mid-January 2026, snowpack levels in the Cascades and the Rockies are at record lows for some stations. In New Mexico, 95% of SNOTEL (snow telemetry) stations are reporting "snow drought" conditions. This is a huge deal because that snow is basically a giant water battery for the summer. Without it, the wildfire season looks grim.
It's a weird paradox. You've got blizzards in the Balkans and snow squalls in Illinois, but the mountains in Colorado are looking unseasonably bare.
Europe’s "Balkan Snow Bomb"
Across the pond, the weather last seven days looked even more intense.
A system nicknamed "Storm Goretti" smashed into the UK and France early in the week. But the real story was the "Balkan Snow Bomb." When that Arctic air hit the warm moisture of the Mediterranean, it created a massive low-pressure system.
Parts of Bosnia and Romania reported nearly 100 cm (that's roughly 40 inches) of snow in a single window.
- Montenegro: Dealt with record-breaking rainfall, nearly 400 mm in some spots.
- Scandinavia: Saw temperatures dip 15°C below the seasonal average.
- The Alps: Finally got a decent dump of snow, but the wind was so high that most ski lifts had to stay closed for half the week.
What Most People Get Wrong About This Pattern
A lot of people think that because it was 60 degrees in Chicago on January 9th, "winter is over."
The weather last seven days proved that's a dangerous assumption. That warmth was actually the "pump" pulling moisture up from the Gulf of Mexico, which provided the fuel for the snow squalls and flooding that followed. We are currently in a weak La Niña phase.
In a weak La Niña, the weather is incredibly "jumpy."
You get these wild swings where one day you're wearing a light jacket and the next you're digging your car out of a drift. It's not a steady cold; it's a series of atmospheric temper tantrums.
Actionable Insights for the Week Ahead
So, what do you actually do with this info?
- Check your tires now. The "flash freeze" phenomenon we saw this week is going to happen again. If your tread is low, you’re going to slide the moment that temperature hits 32°F.
- Watch the "Dew Point." If you see the dew point dropping rapidly while it’s raining, that’s your signal that the rain is about to turn into ice or "black ice."
- Don't trust a clear morning. Many of the accidents on January 14th happened because the morning started sunny. Snow squalls can form and dissipate in 30 minutes.
The weather last seven days was a wake-up call. The Polar Vortex is officially wobbly, and that means the rest of January is likely to be a rollercoaster. Keep your emergency kit in the trunk—even if the forecast looks "clear" when you leave for work.
Next Steps for Staying Safe:
- Download a weather app that specifically sends Snow Squall Warnings, as these are often more urgent than standard winter weather advisories.
- Verify your home’s insulation and pipe protection before the next "leg" of the Polar Vortex arrives later this month.
- Monitor local snowpack reports if you live in the Western U.S., as water restrictions may be implemented earlier than usual this year.
