Honestly, if you've lived in North Texas for more than five minutes, you know the drill. You wake up in a parka and by lunch, you're looking for a short-sleeved shirt and wondering if the AC works. Right now in Sherman, we are staring down a stretch of weather that is basically a rollercoaster of "Texas winter" tropes. If you're looking for the 10 day weather forecast sherman tx, buckle up, because the next week and a half is going to be a wild ride of freezing nights and weirdly sunny afternoons.
The Immediate Outlook: A Chill in the Air
As of early Saturday, January 17, 2026, things are feeling pretty crisp. We are currently sitting at 37°F, but with that northwest wind kicking at 8 mph, it actually feels like 30°F. If you’re heading out for coffee this morning, it’s a "heavy coat" situation.
Today’s high isn't going to do much to warm your soul, topping out at exactly 44°F under cloudy skies. But the real story is tonight. We are looking at a low of 20°F. That is a hard freeze, folks. Make sure your outdoor faucets are covered and the pets are tucked inside.
What the Next 10 Days Look Like
The 10 day weather forecast sherman tx shows a classic back-and-forth pattern. Sunday, January 18, actually looks beautiful but deceptive. We’ll hit 57°F with plenty of sun, but the overnight low drops even further to 19°F. It’s that dry, high-pressure air that lets the heat just vanish the second the sun goes down.

Moving into next week, here is the breakdown of the trends:
- Monday & Tuesday: We stay in the mid-40s to low-50s. Monday (Jan 19) hits 45°F, while Tuesday (Jan 20) warms up to 53°F.
- The Mid-Week Warmup: Wednesday, January 21, is the outlier. We are looking at a high of 59°F. It sounds nice, but it comes with a 35% chance of light rain throughout the day and night.
- Late Week Consistency: Thursday and Friday (Jan 22-23) settle into a groove with highs of 50°F and 56°F. It’s pretty standard January fare for Sherman—not warm, but not "ice storm" territory either.
- The Following Weekend: By Saturday, January 24, and Sunday, January 25, the clouds return. Expect highs around 57°F and 44°F respectively, with Sunday carrying a 40% chance of rain.
Humidity and Wind: The Sherman Factors
People always forget the humidity here. Even in winter, Sherman doesn't always stay dry. By next Wednesday, the humidity is expected to spike to 75%. When you combine that with a 12 mph south wind, it’s going to feel a lot "heavier" than the temperature suggests.
Speaking of wind, it’s mostly coming from the northwest or south this week. Sunday's 15 mph southwest wind will be the strongest of the bunch, so maybe hold off on any outdoor projects that involve lightweight tarps or loose debris.

Understanding the Sherman Winter Reality
Why is our weather so manic? Basically, Sherman sits in a spot where we get the full brunt of those "Blue Northers" coming off the plains, but we’re close enough to the Gulf of Mexico that moisture can sneak up here at a moment's notice. This is why we can go from a 10% chance of snow today to sunny and 57°F tomorrow.
Kinda crazy, right?
Historically, January is our coldest month. While our average highs are usually around 54°F, this particular 10-day stretch is leaning a bit cooler on the front end. It’s important to remember that while the "feels like" temperature matters for your comfort, the actual temperature matters for your pipes and plants. With those 19°F and 20°F lows coming up, the danger is real.

Actionable Steps for the Week Ahead
Don't just look at the numbers; prepare for them.
- Drain the hoses: With the 20°F low tonight and 19°F Sunday night, any water left in garden hoses will freeze and potentially crack your outdoor spigots.
- Layering is King: On Monday and Tuesday, you'll need a heavy layer for the 27°F mornings, but you'll be sweating if you keep it on during the 53°F afternoons.
- Check the Rain Gutters: Since we have a decent chance of rain (up to 40%) later in the forecast, make sure your gutters are clear of those lingering fall leaves so you don't end up with ice dams if the temperature drops after a rain.
- Watch the UV: Sunday has a UV index of 3. It’s not summer-level, but if you’re out hiking at Herman Baker Park for a few hours, the winter sun can still catch you off guard.
Keep an eye on the northwest wind speeds today, especially if you’re driving high-profile vehicles on Highway 75. It’s going to stay gusty at 15 mph through most of the weekend.
Stay warm, Sherman. It’s going to be a cold one tonight.
