Honestly, if you're looking at your phone today and wondering why the "weather today in degree" numbers feel like they’re gaslighting you, you aren't alone. It’s Saturday, January 17, 2026, and the atmosphere is basically throwing a tantrum across the Northern Hemisphere. We’ve got this weird, jagged divide where one half of the U.S. is bracing for a "polar plunge" while the other half is basically ready for a beach day.
It’s messy.
Let’s get into the actual numbers first because that’s why you’re here. If you’re in the Midwest or the Northeast, the weather today in degree readings are hovering in that annoying "slush zone"—mostly between 32°F and 40°F (that’s roughly 0°C to 4°C for the metric fans). But here’s the kicker: the humidity is high, and there’s a clipper system dragging across the Great Lakes into New England. This means that even if your screen says 38°F, the wind chill is making it feel like a damp 25°F. It’s that bone-chilling cold that sticks to your clothes.
The Great Temperature Divide of 2026
If you look at the map right now, it looks like a tie-dye shirt gone wrong.
In the American West, it’s a totally different story. Places like Denver are seeing highs near 33°F, but parts of the Southwest and California are pushing into the 70s and even 80s. It’s unseasonably warm. Meteorologists at the National Weather Service have been tracking this persistent ridge of high pressure that’s basically acting like a bodyguard, keeping the cold air trapped in the East.

- The "Florida Freeze": Even the Sunshine State is panicking. Tallahassee is looking at near-freezing levels tonight, and there’s even talk of light snow flurries in North Florida. Yes, actual snow in Florida.
- Global Heat Trends: Despite this local chill, 2025 was just ranked the third warmest year on record by the Copernicus Climate Change Service.
What most people get wrong about the weather today in degree is focusing only on the "High." The "Low" is where the real story is today. In the Upper Midwest—think Minnesota and the Dakotas—the mercury is set to dive into the negative double digits tonight. We’re talking -10°F to -20°F. When it’s that cold, the air can’t hold moisture, which is why it feels so "sharp" and dry.
Why the Forecast Feels Different Depending on Your App
Have you ever noticed that Apple Weather, AccuWeather, and the local news all give you different numbers for the weather today in degree? It’s not because they’re guessing. It’s about the models.
Most apps rely heavily on the GFS (Global Forecast System) or the ECMWF (the "European" model). Right now, the European model is winning for the Mid-Atlantic. It correctly predicted that the wintry mix in Baltimore and D.C. would turn to rain by midday, while other models were still screaming about a snow-pocalypse.
Across the pond, Europe is dealing with its own weirdness. London is sitting at a crisp 7°C (45°F) with light drizzle, while parts of Scandinavia are seeing record-breaking lows. Meanwhile, in Taiwan, the Central Weather Administration is warning of a "cold air mass" that could drop temperatures to 12°C next week—which, for a tropical climate, is basically an ice age.

Real-World Impact: More Than Just a Number
This isn't just about whether you need a scarf.
The aviation industry is currently battling those snow squalls in Ohio and Pennsylvania. If you’re flying through Cleveland or Pittsburgh today, expect delays. The NWS issued a warning about "whiteout conditions" that can happen in seconds. It’s that terrifying moment where the weather today in degree doesn't matter as much as the visibility, which is dropping to less than a quarter-mile in some spots.
Then there's the space weather. Fun fact: we’re currently near the peak of Solar Cycle 25. While you’re looking at rain or snow, there’s a stream of high-speed solar wind (about 700 km/s) hitting Earth’s magnetosphere. This means if you’re far enough north—like in the Arctic Circle or even parts of Canada—you’re likely seeing some insane auroras tonight.
How to Actually Use Today's Weather Info
Don’t just look at the big number on your home screen. To stay ahead of this January mess, you need to check the "Dew Point."

If the dew point is close to the actual temperature, you’re going to get fog or nasty, sticky precipitation. If there’s a wide gap, it’ll feel much drier and probably "cleaner" outside. Also, pay attention to the pressure. A rapidly falling barometer usually means that clipper system is about to dump its load of slush right on your driveway.
Basically, if you’re in the path of the cold front, your Saturday is for indoor hobbies. If you’re in the West, get outside before the "January Thaw" ends, because the long-range forecast from the Farmers' Almanac suggests a much more brutal February is coming for everyone.
What You Should Do Right Now
- Check your tire pressure. Cold air makes the air inside your tires contract. A 10-degree drop in temperature can result in a 1-2 PSI loss. If your "low tire" light is on today, it's likely just the physics of the weather today in degree at work.
- Drip those pipes. If you are in the South (Alabama, Georgia, Florida) and aren't used to these freezing temps, don't risk it. A slow drip can save you a $5,000 plumbing bill.
- Layer up properly. Skip the heavy cotton. Go with a moisture-wicking base, an insulating middle (like fleece), and a wind-blocking outer shell.
Stay warm, stay dry, and maybe stop checking the app every five minutes—it's not going to get any warmer until Tuesday.
