If you’ve lived in East Texas for more than five minutes, you know the drill. You wake up in Tyler, look at your phone, and see a 30% chance of rain. By noon, you're looking for an ark because the Rose City is underwater. Then, by 4:00 PM, the sun is out, it's 75 degrees, and you’re wondering why you even wore a jacket.
Planning your life around a 30 day weather forecast Tyler TX is kinda like trying to predict which lane at the Brookshire’s on Rice Road will move the fastest. It's a gamble. But here’s the thing: we actually have some solid data for the next month that goes beyond "it might rain."
Right now, as we sit in mid-January 2026, the atmosphere is doing something weird. We’re shaking off the last bits of a weak La Niña. For the non-weather nerds, La Niña usually means East Texas stays dry and stays warm. But the pattern is breaking. We’re sliding into what experts call "ENSO-neutral," and honestly, that makes the next 30 days a bit of a wild card.
The Immediate Outlook: Late January and Early February
Let's talk numbers. Real ones.
Historically, January is Tyler's coldest month. We usually see highs around 58°F and lows hovering near 38°F. However, the 2026 setup is leaning a bit warmer than that average. Looking at the back half of January, you should expect several "false springs." We’re talking days where it hits 65°F or even 70°F, followed by a sharp, "slap-you-in-the-face" cold front that drops us back into the 30s overnight.
Specific dates to watch? The window between January 21 and January 25 looks particularly soggy.

There’s a strong signal for a Gulf moisture surge. In East Texas, that usually doesn't mean a light mist. It means heavy, gray-sky rain that sticks around for 48 hours and makes the pine needles in your yard a slippery mess. If you're planning a trip to the Azalea Residential Historic District for a walk, maybe aim for the 26th through the 30th instead.
February's Temperature Rollercoaster
February in Tyler is famous for one thing: mood swings.
The first week of February 2026 is trending "unseasonably warm." We’ve seen this pattern before where the jet stream retreats north, letting that humid air from the Gulf of Mexico creep up Highway 69. Expect highs near 64°F. But don't go planting your geraniums just yet.
There is a 40% chance of a significant "blue norther" hitting somewhere around the second week of February. When these cold snaps hit East Texas, they hit hard because the humidity makes the cold feel "heavy." It’s that damp chill that gets into your bones even if the thermometer only says 35°F.

Why the 30 Day Weather Forecast Tyler TX is Shifting
People always ask why the forecast changes so fast here. It's the geography. Tyler sits right in the "battle zone" between dry air from West Texas, cold air from the Plains, and wet air from the Gulf.
- The Jet Stream Factor: Right now, the subtropical jet is becoming more active.
- The "Neutral" Transition: Because we are moving out of La Niña, the "block" that keeps rain away is gone.
- The Smith County Microclimate: Tyler’s elevation—yes, we have some—and our dense tree cover actually trap humidity differently than places like Dallas.
If you’re looking at a 30-day window, you’re basically looking at a transition from "dry and mild" to "wet and unpredictable."
Snow? Don't Bet the Farm
Every year, someone on Facebook posts a fake "blizzard warning" for Tyler. Let’s be real. Snow in Tyler is a rare treat (or a disaster, depending on if you have to drive on Broadway).
For the next 30 days, the probability of measurable snow—meaning enough to actually make a snowball—is less than 5%. We might see some "wintery mix" or sleet during those mid-February cold fronts, but the ground is likely too warm for anything to stick. If you want a white winter, you’re probably better off driving six hours north.
Practical Steps for the Next 30 Days
Stop checking the "daily" forecast three weeks out. It’s useless. Instead, focus on the trends.
First, keep the "layering" strategy alive. You’ll need a heavy coat at 7:00 AM and a t-shirt by 2:00 PM. That’s just the Tyler tax. Second, if you have outdoor projects—maybe clearing out the brush before the spring growth starts—target the last week of January. It looks to be the driest window we have before the February rains really kick in.
Also, check your gutters. With the shift toward a wetter pattern, those East Texas pine needles are going to cause overflows during the heavy downpours expected in late January.
The most important thing to remember about the 30 day weather forecast Tyler TX is that it’s a guide, not a gospel. Keep an eye on the local radar when the clouds start looking heavy over the Smith County Courthouse, and always keep an umbrella in the back seat of the truck. You’re going to need it.
To stay ahead of the weather, make sure your NOAA weather radio is programmed for Smith County and keep a close eye on the short-term updates as those Gulf moisture surges move in.
