If you’ve stepped outside lately and felt that particular kind of bite in the air—the one that makes your nostrils stick together—you aren't alone. Winter is finally acting like winter. For those asking what is the weather like next week, the short answer is: messy, cold, and potentially historic for some of us. We are currently watching a massive atmospheric drama unfold. The Polar Vortex, that swirling pool of frigid air usually trapped at the North Pole, is basically having a mid-life crisis. It’s splitting.
When the vortex weakens or "splits," it doesn't just stay up there. It leaks. And right now, it’s leaking straight into the continental United States and parts of Europe. Starting Monday, January 19, 2026, we’re looking at a weather pattern that meteorologists call "highly volatile."
Basically, the jet stream is buckling. On the West Coast, it’s bulging north, which means California and the Pacific Northwest might actually stay relatively mild. But for everyone east of the Rockies? You're in the "dip." That dip is acting like a vacuum, sucking Arctic air from deep in Canada and dumping it into the Midwest, the Great Lakes, and eventually the Northeast.
Why the Polar Vortex Is Ruining Your Monday
Monday morning, January 19, is going to be a wake-up call for the Midwest. In cities like Chicago and Detroit, wind chills are expected to dive well below zero. It’s not just the "cold" you're used to; it's that piercing, persistent Arctic air.
Honestly, the setup is a bit of a nightmare for commuters. We just saw 3 to 6 inches of dry, powdery snow hit the Detroit Metro area on the 15th, and next week looks to follow that same "nickel-and-dime" pattern. Meteorologist Ray Russell recently noted that this isn't necessarily one giant, historic blizzard. Instead, it’s a series of waves. You get a dusting, then a freeze, then another two inches. It adds up.
The Southeast Isn't Safe This Time
If you’re in the South, you might think you’re exempt. You aren’t.
By Tuesday and Wednesday (Jan 20-21), that cold air is expected to bleed into the Tennessee Valley and even the Carolinas. Forecasters at the National Weather Service in Raleigh are already keeping an eye on "cold air damming." That’s a fancy way of saying cold air gets trapped against the mountains, creating a perfect recipe for black ice and wintry mixes.
Wind chills in the Triangle area of North Carolina could hit the teens by Wednesday morning. If you've lived in the South for more than a week, you know that’s enough to send everyone to the store for bread and milk.

What Is The Weather Like Next Week Across The Regions?
Breaking it down by region makes the most sense because the US is currently a divided house. The West is playing a completely different game than the East.
The Northeast and Mid-Atlantic
Expect a "trough" to settle in. This is a zone of low pressure that essentially invites cold air to stay for dinner and sleep on the couch. From New York City to Boston, temperatures will likely hover 5–10 degrees below their January averages. We’re talking highs in the 20s. Precipitation is the big question mark. While a major Nor'easter isn't a lock yet, the "slight risk" of heavy snow for the Jan 23-25 window is very real according to the Climate Prediction Center.
The Midwest and Great Lakes
This is the "deep freeze" zone. Highs in the 10s. Lows in the single digits. Lake effect snow is going to be a constant companion for places like Buffalo and Cleveland. The air is so cold that road salt starts losing its effectiveness, which is something you really need to keep in mind if you're driving I-90.
The West Coast and Rockies
You guys are the winners next week. A strong ridge of high pressure is building over the Pacific. This means San Francisco and Los Angeles will likely see above-average temperatures. It’s the "warm bulge" of the jet stream. Even the Pacific Northwest, which usually gets hammered with rain this time of year, might see some drier, clearer days.

The Deep South and Florida
Florida is staying mostly dry, but the "Big Freeze" will reach the Panhandle. By midweek, northern Florida could see frost. The rest of the Southeast is looking at a "wetter than average" trend. When you mix that moisture with the incoming Arctic air, you get that nasty freezing rain that downs power lines.
The La Niña Factor
We are currently in a weak La Niña phase. Usually, La Niña means a warmer, drier South and a colder, wetter North. But 2026 is being weird. The Madden-Julian Oscillation (MJO)—a moving "pulse" of clouds and rain in the tropics—is currently interfering with the standard La Niña pattern.
This interference is why the forecast is so jumpy. One day the models show a clear sky, the next they show a "Siberian Express" bringing 10 inches of snow. As Paul Pastelok from AccuWeather pointed out, the jet stream is stretching the polar vortex, which creates these "repeated shots of cold air."
European Outlook: Siberia Is Sending A Gift
It’s not just North America. The same polar vortex disruption is sending cold air westward from Siberia into Europe. London and Paris, which have had a relatively mild winter so far, are looking at a sharp drop in temperatures toward the end of next week. Scandinavia is already feeling it, with Arctic waves disrupting travel in Lapland.

Survival Tips for the Jan 19-25 Window
Since we know the cold is coming, here is how you actually handle it without losing your mind.
- Check your tires now. Cold air makes tire pressure drop. If your "low pressure" light isn't on yet, it will be by Tuesday.
- The 3-Layer Rule. Don't just wear one big coat. Wear a moisture-wicking base, an insulating middle (fleece is king), and a wind-blocking outer shell.
- Drip your pipes. If you're in the South and your house isn't built for 15-degree nights, leave the faucet at a slow drip. A plumbing bill is way more expensive than a slightly higher water bill.
- Watch the "Black Ice" window. In the Mid-Atlantic, we often see a "wintry mix" turn to rain and then flash-freeze at sunset. Tuesday night looks particularly risky for this.
The models are still fighting over the specifics of the weekend of Jan 24-25. Some show a major storm developing along the coast, while others show the cold air pushing the moisture out to sea.
Actionable Next Steps
To stay ahead of this shifting pattern, your best bet is to check the hourly forecast rather than the daily one. The timing of the "Arctic front" is everything. If it hits at 4 PM, your commute is a mess. If it hits at midnight, you're just waking up to a frosty windshield.
- Download the NWS (National Weather Service) app or bookmark their local office page for your city; they are the gold standard for accuracy.
- If you are traveling through Chicago (ORD) or Detroit (DTW) next week, keep a close eye on flight statuses starting Monday evening.
- Check your emergency car kit—ensure you have a real ice scraper and a blanket.
This isn't just a "cold snap." It’s a systemic shift in the atmosphere that’s going to define the rest of January. Stay warm out there.
