So, you’re standing in the parking lot of the Carrollton Town Center, looking at your phone, and the app says it's 56°F and "sunny." But you're shivering. Why?
Honestly, Texas winter is a mood. One hour you’re soaking up the vitamin D, and the next, a gust of wind hits you from the south at 9 mph, making that 56°F feel more like 53°F. It’s that specific North Texas bite. If you’ve lived here long enough, you know that hourly weather Carrollton TX isn't just a search term; it’s a survival strategy for your wardrobe.
Today, Thursday, January 15, 2026, is a perfect example of why "sunny" is a deceptive word.
The Reality of Today's Hourly Shift
Right now, we are sitting at a crisp 56°F. It sounds manageable. But the humidity is remarkably low—only 31%. In Carrollton, low humidity in January usually means the air has zero "blanket" effect. The heat just escapes.

The wind is currently coming from the south, but as we move through the afternoon, expect a slight shift. The daily forecast predicts a high of 56°F (which we are hitting right about now) and a plummet down to a low of 33°F tonight.
That is a 23-degree swing.
Think about that. You leave for a late lunch in a light sweater, and by the time you're heading home after dark, it’s literally freezing. This is why everyone in Denton County keeps a "car jacket."

The Afternoon Breakdown
- Current (4:35 PM): 56°F, Sunny, 9 mph South wind.
- The Sunset Transition: UV index is at 0 now, so the sun isn't doing much to warm your skin. Once it dips below the horizon, that 56°F will start its steady slide toward the 30s.
- Overnight: Clear skies. While "clear" sounds nice for star-gazing, in Carrollton, it's basically an open door for cold air. No cloud cover means no insulation.
What the Averages Don't Tell You
If you look at historical data for Carrollton in January, the "average" high is 57°F. We are right on the money today. But "average" is a liar. It doesn't account for the days when a Blue Norther screams through and drops the temp 40 degrees in three hours.
Luckily, today isn't one of those "ice-pocalypse" days. We have a 0% chance of precipitation. No rain, no sleet, no "wintry mix" to worry about on I-35E.
But here is the thing: the wind. Even at 9 or 10 mph, in this dry air, it carries a chill. The southwest wind forecast for the rest of the day is relatively gentle compared to the 25 mph gusts we sometimes see, but it’s enough to keep the "feels like" temp lower than the number on your dashboard.

Managing the Carrollton "Micro-Climate"
Because Carrollton sits in that sweet spot between Dallas and the more open plains to the north, we get a weird mix of urban heat and rural wind.
If you're near the Elm Fork Trinity River, it’s always a couple of degrees cooler and a bit more damp. If you're over by the Shops at Willow Bend border, the concrete might hold a little more heat.
Basically, you've got to dress in layers. It's the only way. A base layer for the 33°F morning, a light layer for the 56°F afternoon, and a heavy coat for the clear, freezing night ahead.
Actionable Steps for Tonight
Since we know the temperature is headed toward 33°F with clear skies, here is what you actually need to do:
- Check your tires: Drastic temp drops like this (from the 50s to the 30s) can trigger your "low tire pressure" light. It’s not a leak; it’s just physics.
- Pet Check: If your dogs are used to being outside during the day, bring them in tonight. 33°F is too close to freezing to leave them out without serious shelter.
- Hydrate: Dry air (31% humidity!) dehydrates you faster than you realize. Drink water, even if you aren't "hot."
The rest of the week looks to stay mostly sunny, with tomorrow's high creeping up toward 61°F, though the winds will kick up significantly from the north. Enjoy the calm of this afternoon while it lasts.
