Honestly, if you've lived in North Texas for more than a week, you know the drill. One day you're wearing a parka, and the next you're thinking about turning on the AC. Right now, the DFW extended weather forecast is doing that classic Texas dance—a literal temperature rollercoaster that’s got everyone from meteorologists to casual commuters checking their apps every hour.
We just came off a Saturday that felt like a true slap of winter.
Today, Sunday, January 18, 2026, things are shifting. We started the morning with a bite in the air—a crisp 26°F that felt more like 21°F thanks to a light northwest wind. But don't let that fool you into staying under the covers all day. By this afternoon, we’re looking at a high of 60°F under full, glorious sun. That is a 34-degree swing in less than twelve hours. Basically, you’ll start in a heavy coat and end the day in shirt sleeves.
The Mid-Week Moisture Mystery
People keep asking if we're finally going to see some real rain. The short answer? Maybe, but don't cancel your outdoor plans just yet.

Monday and Tuesday (January 19–20) look pretty quiet, albeit cooler. We’re dropping back down into the 48°F to 52°F range for highs, with lows hovering right at the freezing mark. It’s that "seasonal" cold that feels annoying because it’s not quite cold enough for snow but just chilly enough to be uncomfortable.
Then comes Wednesday, January 21.
This is the day to watch. The National Weather Service out of Fort Worth is tracking a disturbance moving in from the southwest. We’re currently looking at about a 45% chance of rain during the day. Humidity is going to spike to around 84%, so it’ll feel damp and heavy. If you’re heading out, that’s your window for potential wet windshields and slow traffic on I-35.
Why the "Snowmageddon" Rumors are Probably Wrong
Every time the temperature drops in January, the "snowmageddon" posts start circulating on social media.

Let's look at the actual data for the end of the month. Looking toward next weekend—specifically Saturday, January 24, and Sunday, January 25—the forecast stays mostly cloudy with highs in the 50s. While there's a light rain chance (about 35%) on that Sunday, the atmospheric profile just isn't there for the white stuff.
Actually, the most interesting part of the current outlook is what’s happening on Tuesday, January 27. We’re seeing a slight chance of light rain mixing with snow overnight as the low drops to 33°F.
Is it going to stick? Highly unlikely.
The ground is still too warm from those 60-degree days, and the "feels like" temperatures aren't staying low enough for long enough. We’re basically looking at "nuisance" weather rather than a winter wonderland.

Fire and Ice: The Hidden Danger
While everyone is worried about freezing, the real expert concern right now is fire.
It sounds weird for January, but because it's been so dry, we’ve got elevated fire weather conditions, especially west of the Metroplex. Today, those southwest winds are kicking up to about 12 mph. When you combine that with humidity levels as low as 29%, even a small spark in a grassy field can get out of hand fast.
It’s the weird duality of Texas winters: freezing in the morning, fire risk in the afternoon.
Looking Ahead: The Final Week of January
As we head toward the close of the month, the trend seems to be "seasonably cool."
- Monday, Jan 26: Partly sunny, high of 41°F, low of 33°F.
- Tuesday, Jan 27: High of 42°F with those light rain/snow flurries mentioned earlier.
- Wind Factors: Most of our wind is coming from the North or Northeast during this stretch, keeping that "chill factor" alive even when the sun is out.
If you’re planning any travel through DFW Airport, keep an eye on that Wednesday (Jan 21) window and the following Sunday (Jan 25). Those are the primary spots where rain could actually cause a few "gate hold" delays.
Next Steps for DFW Residents:
- Check your tire pressure: These 30-degree daily swings are notorious for triggering your "low tire" light.
- Hydrate your plants: It’s been dry. Even if it's cold, your foundation and your evergreens need a little drink before the next freeze hits.
- Layering is king: Forget the heavy parka for the whole day. Wear a base layer with a windproof shell you can toss in the backseat by 2:00 PM.
