Honestly, if you stepped outside in Killeen this morning, you probably felt that sharp, 30-degree bite. It’s that classic Central Texas winter move where the air feels like a refrigerator until the sun finally climbs high enough to do its job. But here is the thing: the weather in Killeen today is actually turning out to be one of those perfect, crisp Texas days that make the summer humidity almost worth it.
We are looking at a high of exactly 60°F.
It’s sunny. Like, aggressively sunny.
By about 3:32 PM, the west wind was humming along at 10 mph. It’s not a gale, but it’s enough to make you second-guess wearing just a t-shirt if you’re standing in the shade. The humidity is sitting at a bone-dry 19%. That’s low. If your skin feels a bit tight or you’re reaching for the chapstick every twenty minutes, that’s why.
What is actually going on with the weather in Killeen today?
When we look at the numbers provided by the first Google Weather data pull for this Sunday, January 18, 2026, the contrast is what jumps out. You’ve got a 30-degree spread between the high and the low. That is a massive swing for a single 24-hour period, but for folks around Fort Cavazos (formerly Fort Hood), it’s basically just a Tuesday. Or a Sunday, in this case.

The dew point is hovering in the teens. That means there is almost zero moisture in the air.
While the UV index is technically a 3 (which is moderate), don't let the "winter" label fool you. Texas sun hits different. You can still get a burn if you’re out hiking at Dana Peak Park for three hours without thinking about it.
The wind is coming from the west-southwest. This is significant because it usually brings in that drier, continental air. We aren't getting that moist Gulf of Mexico breeze today. Instead, it’s that dry, dusty air that keeps the sky looking that specific shade of deep blue.
A breakdown of the Sunday vibe
- Current Temp: 60°F.
- The Low: 30°F (Yeah, it was freezing).
- Wind: West at 10 mph.
- Precipitation: 0%. Literally zero chance of rain or snow today.
Most people get the "winter in Texas" thing wrong. They think it’s either a freak ice storm or basically summer. Today is that rare middle ground. It's cool enough to justify a light jacket but warm enough that you’ll be carrying it by 2:00 PM.

The cedar fever factor
Even though the weather in Killeen today looks beautiful through a window, there is a hidden villain. Mountain Cedar.
With the humidity at 19% and a 10 mph wind from the west, the pollen count is likely doing numbers. Experts like those at the Texas A&M AgriLife Extension often point out that dry, windy days in January are the primary triggers for "Cedar Fever." If you’re sneezing and your eyes are itchy, it’s not a cold. It’s the trees.
The air is very bright. AccuWeather actually uses a "Brightness Index," and today would be near the top. Between the 0% cloud cover and the low humidity, there’s nothing to scatter the light. It’s high-contrast weather.
Why this matters for your evening
As soon as that sun dips, the temperature is going to crater. We’re talking about a drop back down toward that 30°F mark.

If you're heading out to dinner or catching a movie at the Killeen Mall, do not trust the afternoon warmth. The "feels like" temperature is going to plummet the second the sun isn't hitting your face.
The west wind at 11 mph might pick up slightly as the thermal layers shift during sunset. This creates a wind chill effect that can make 45°F feel like 38°F.
Actionable steps for Killeen residents
- Hydrate everything: With 19% humidity, you are losing moisture faster than you realize. Drink more water than usual and use a heavy-duty moisturizer.
- Layer like a pro: A windbreaker over a hoodie is the play today. You need to be able to shed layers as the temp hits 60°F but bundle up the second you hit a shadow.
- Check your tires: Large temperature swings (from 30°F to 60°F) can mess with your tire pressure. If your "low air" light came on this morning, it might go off once it warms up, but it's worth a quick check at the gas station.
- Sun protection: It sounds silly for a 60-degree day in January, but with a UV index of 3 and zero clouds, 20 minutes of direct exposure is enough to cause damage if you have sensitive skin.
The weather in Killeen today is essentially a gift before the next front rolls through. It’s clear, it’s dry, and it’s predictably unpredictable. Enjoy the sunshine while it lasts, because in Central Texas, the next "Blue Norther" is always just a few days away.
