Honestly, if you've lived in Stephenville for more than a week, you know the drill. You wake up needing a heavy parka and by lunchtime, you’re looking for a short-sleeved shirt and wondering why the AC is kicking on. That’s just the "Cowboy Capital" way of doing things.
Today, Thursday, January 15, 2026, is basically a poster child for that Texas volatility. We’re looking at a high of 65°F with nothing but sun. It sounds like a dream, especially since the humidity is sitting at a crisp 47%. But don't let the afternoon sunshine fool you into a false sense of security.
Tonight, the temperature is going to dive. Fast.
The low is bottoming out at 30°F. That’s a 35-degree swing in a single day. If you leave your sensitive porch plants out, they’re toast. It’s that weird time of year where the southwest winds at 13 mph feel great at 2:00 PM but bite like a stray dog once the sun drops behind the horizon.

People think Texas winters are just "mild." Tell that to someone standing in the wind on the Tarleton campus in the middle of January.

While today is sunny and pleasant, things are shifting. By tomorrow, Friday, January 16, the wind is flipping. A north wind is coming in at a sustained 21 mph, dropping our high to 58°F. Not terrible, right? Except the low hits 33°F and that wind chill will make it feel like the fridge was left open.
Saturday is when the "real" winter shows up. We’re talking a high of only 46°F and a bone-chilling low of 26°F. If you’re planning on heading to the downtown square or hitting up the local cafes, you'll want the heavy layers.
Here is the quick breakdown of what to expect for the rest of the week:
- Sunday, Jan 18: Back to sunny skies. High 61°F, Low 28°F.
- Monday, Jan 19: Partly sunny and a bit cooler. High 53°F, Low 29°F.

Why Erath County Weather Is So Unpredictable
You’ve gotta understand the geography here. Stephenville sits in this transition zone. We aren’t quite the Hill Country, and we aren’t quite the Panhandle. We’re right in the middle where the dry air from the west slams into whatever moisture is trying to crawl up from the Gulf.

Historically, January is our coldest month. The average high is usually around 59°F, so this 65°F peak today is actually a bit of a gift. But remember February of 2021? Or the snow event in early 2025? Erath County has a memory for the "Big Freeze," and even when the forecast looks clear, locals keep one eye on the sky.
The humidity today is low at 29% for the current conditions, which is why the air feels so "thin" and sharp. It’s great for keeping the "muggy" feeling away, but it’s terrible for your skin and even worse for static electricity. You’ll be shocking yourself on every car door in the H-E-B parking lot today.
Rain and Snow: Are We Seeing Any?
The short answer is: probably not.
The current weather forecast for Stephenville Texas shows a 0% chance of precipitation for today and tomorrow. There is a tiny 10% chance of some rain or light snow flurries moving in around Monday and Tuesday, but don't go buying a sled just yet. In this part of Texas, a 10% chance usually just means the clouds will look a little extra grey while you go about your business.

Actually, the "wettest" day in the immediate 10-day outlook isn't until next Sunday, January 25, when we might see a 35% chance of rain.
What You Should Do Today
Since the UV index is hitting a 3 (Moderate), you can actually spend some time outside without feeling like you're in a toaster or a freezer. It’s the perfect day to get those outdoor chores done before the weekend freeze hits.
- Water your foundation: It's been dry. That 29% humidity means the ground is thirsty, and Erath County clay loves to crack.
- Check your tires: Big temperature swings—like today’s 35-degree drop—cause tire pressure to fluctuate. If your "low air" light comes on tomorrow morning, that's why.
- Prepare the pipes: Saturday night is going to be 26°F. If you have exposed pipes, wrap them now while it’s 65°F and sunny instead of fumbling with duct tape in the dark and cold.
Keep an eye on the wind speeds too. Those 21 mph gusts on Friday will blow your trash cans into the next county if they aren't secured.
Basically, enjoy the 60s while they last. Stephenville is beautiful when the sun is out, but she’s got a cold heart waiting for us this weekend. Stay warm, keep your layers handy, and maybe grab an extra bag of salt for the steps just in case that 10% chance of moisture decides to get serious.
