If you woke up in Plano this morning thinking it was finally time to ditch the heavy coat, Mother Nature had other plans. North Texas is famous for its mood swings, and today, January 14, 2026, is a classic example of that "wait five minutes and it'll change" philosophy. We are currently sitting in the middle of a cool-down that’s basically a reminder that winter isn't done with us quite yet.
What’s Happening with Weather in Plano Texas Today?
Right now, the mercury is hovering around 59°F. It’s mostly cloudy, which makes the air feel a bit heavier than the number on the thermometer suggests. If you’re heading out to Legacy West or just running errands near Parker Road, keep a windbreaker handy. Why? Because the wind is coming out of the north at about 16 to 18 mph, and those gusts can bite.
Honestly, the high for today is only hitting 60°F. That’s a bit of a tease. You see the sun peek out for a second—it's technically "partly sunny" right now—and you think it’s going to warm up. It won’t. That north wind is a direct result of a cold front sliding through the DFW metroplex. It’s dry, it’s brisk, and it’s keeping things from getting comfortable.

The Tonight Transition
The real story starts when the sun goes down. Tonight, the clouds are expected to clear out completely. While clear skies sound nice, in January, they’re a recipe for a "radiational cooling" event. Without a cloud blanket to trap the day's heat, temperatures are going to plummet.
Expect a low of 34°F by the time you're waking up tomorrow.

There’s even a tiny, 5% chance of some stray snow flurries overnight. Don't go buying a sled. It’s mostly just a quirk in the atmospheric moisture levels as the front passes. It’s much more likely to just be a very cold, very dry night. Humidity is dropping to around 30-40%, which is typical for these post-front conditions in Collin County.
Breaking Down the Hourly Reality
Weather isn't just one number; it's a timeline. If you’re planning your day, here is the vibe for the next few blocks of time:

- Late Afternoon (3 PM - 6 PM): Temperatures will hold steady near 59°F before starting their descent. The wind will remain the biggest annoyance. If you're walking the dog, the wind chill will make it feel more like the low 50s.
- Evening (7 PM - 10 PM): This is when the drop happens fast. We’ll slide through the 40s quickly. The sky will be beautiful and clear, though.
- Midnight and Beyond: We hit the 30s. This is when you want to make sure the "P's" are covered: People, Pets, and Pipes (though at 34°F, your pipes are likely fine, it's just good practice in Texas).
Why Plano Weather is So Random in January
Statistically, mid-January is the coldest time of the year for us. According to data from the National Weather Service in Fort Worth, our "normal" high for this date is about 56°F. So, hitting 60°F today actually puts us slightly above average, even if it feels chilly.
The geography of Plano doesn't help. We are essentially a flat plain. There are no mountains to block the "Blue Northers" that scream down from Canada, through Oklahoma, and right into our backyards. That's why you can have a 70-degree day followed by a freeze 12 hours later. Today isn't that extreme, but the "breezy and cool" pattern is a direct result of that open-air corridor.
Cedar Fever Alert
If your eyes are itchy and you’re sneezing, it isn’t just a cold. The Cedar/Juniper pollen levels are currently in the medium-high range. High pressure and north winds are the perfect delivery system for mountain cedar pollen from the Hill Country. Even though the wind is "clean" from the north, it’s carrying those allergens right into your sinuses. Keep the antihistamines close.
Actionable Tips for Today
- Layer Up: The 26-degree swing between today’s high and tonight’s low means you need layers. A light jacket is fine now, but you’ll want a real coat if you’re out past 8 PM.
- Fire Safety: With humidity dropping to near 30%, the fire threat is elevated. Avoid any outdoor burning or tossing cigarette butts. The grass is dormant and dry; it only takes a spark and this wind to start a problem.
- Check Your Tires: Significant temperature drops cause air pressure in tires to dip. If your "low tire" light comes on tomorrow morning, it’s likely just the cold air making the molecules huddle together.
- Hydrate Your Skin: That 34% humidity is a moisture-killer. If you feel like a lizard by dinner time, that’s why.
Tomorrow looks sunny with a high of 59°F, basically a carbon copy of today but with less wind. For now, enjoy the crisp air and keep an eye on that sunset—clear Texas winters make for some of the best orange and purple horizons you'll ever see.
