You’ve lived here long enough to know the drill. One minute you’re walking the Blue Trail at the Hebron Lakes in a light hoodie, and three hours later, you're sprinting to the garage to cover the outdoor spigots because a "blue norther" just screamed across Denton County. Honestly, carrollton tx weather hourly isn't just a search term; it's a survival tactic for anyone trying to plan a life in the DFW Metroplex.
Right now, as we sit in mid-January 2026, the air has that specific North Texas bite. As of late Friday night, it’s a crisp 40°F outside, but with that northwest wind kicking at 7 mph, the "feels like" temperature is already dipping to 36°F. It’s the kind of cold that sneaks into your joints if you aren't moving.
The Midnight Slide and Today's Forecast
If you're looking at the clock right now, the carrollton tx weather hourly trend is heading straight into a freezing basement. We’re coming off a Friday where it actually hit 56°F, which felt almost civilized. But tonight? We are looking at a low of 25°F. That is a massive drop that usually catches the "I'll just leave the sprinklers on" crowd off guard.

Basically, Saturday is going to be a gray, cloudy slog. We aren't seeing a ton of sun today. Expect a high of only 43°F. With the wind shifting to come directly out of the north at 11 mph, it’s going to feel significantly colder than the number on your phone screen.
- Humidity: 25% (dry enough to make your skin feel like parchment).
- Precipitation: 10% chance of a stray sprinkle during the day, but zero chance of the white stuff tonight.
- UV Index: 0. You won't need the sunscreen, but you’ll definitely need the lip balm.
Why Sunday is the Real Plot Twist
Here is where North Texas weather gets weird. Sunday, January 18, is going to wake up at a bone-chilling 24°F—the coldest point of this stretch. But then, the wind flips. It starts coming from the southwest at 11 mph, and by lunch, we’re back to full-blown sunshine.

By the afternoon, we hit 58°F. That is a 34-degree swing in about ten hours. If you’re planning on hitting the shops at the Historic Downtown Carrollton Square on Sunday afternoon, you’ll start in a parka and end in shirtsleeves. It’s classic Carrollton.
The 4 P's and Why They Actually Matter
Kinda seems like every local news station repeats the "4 P's" until they're blue in the face, but when you see a 24°F low on the horizon, it’s for a reason.

- People: Check on the neighbors who might be relying on old space heaters.
- Pets: If it's too cold for you to stand in the yard barefoot for ten minutes, it's too cold for them. Bring them in.
- Pipes: Drip those faucets. Open the cabinet doors under the sinks. It’s a lot cheaper than calling a plumber on a Sunday morning.
- Plants: Anything you haven’t moved inside by now is basically a popsicle.
Looking Ahead: The Rain is Coming
Don't get too comfortable with the dry air. While Monday and Tuesday stay relatively calm with highs in the 50s, Wednesday (January 21) brings the moisture back. We're looking at a high of 62°F, which sounds great until you see the 71% humidity and the increasing chance of rain.
By Wednesday night, there’s a 35% chance of showers. This leads into a seesaw of a week where temperatures fluctuate between 49°F and 59°F. The real mess hits next Sunday, January 25, where the chance of rain jumps to 70% and the humidity maxes out at 96%.
Actionable Steps for the Next 24 Hours
Stop checking the app every five minutes and just do these three things:
- Layer Up for Saturday: If you’re heading to the Carrollton Public Library or out for groceries, go with three layers. A base moisture-wicking layer, a warm middle, and a wind-resistant outer shell. That north wind at 11 mph will cut right through a cheap fleece.
- Vehicle Check: This dry, cold air kills batteries that are on their last legs. If your car groaned a bit this morning, it might not start on Sunday at 24°F.
- Irrigation: Turn off your automatic sprinklers. The City of Carrollton actually offers a free rain and freeze sensor program—take advantage of it so you aren't that person creating an ice rink on the sidewalk.
The carrollton tx weather hourly dance is all about the transition. We’re moving from a clear, cold night into a cloudy, biting Saturday, followed by a sun-drenched but freezing Sunday morning. Stay warm, keep your pipes dripping, and maybe grab a hot coffee at one of the spots off Belt Line. You're going to need it.
