If you’ve lived in North Texas for more than five minutes, you know the local weather has a bit of a personality disorder. One day you’re wearing flip-flops at a Backyard BBQ, and twelve hours later, you’re scrambling to find the frost blankets for your succulents. Predicting the 30 day weather forecast for fort worth tx is basically like trying to guess which way a cat will jump. Honestly, it’s a gamble.
Right now, as we sit in mid-January 2026, the pattern is doing exactly what North Texas does best: keeping us on our toes. We just came off a New Year’s stretch where temperatures hit the 70s—nearly 15 degrees above the usual January baseline. But don’t let that spring-like vibe fool you. The atmosphere is currently shifting, and the "January Thaw" we’ve been enjoying is about to hit a wall.
The Immediate Outlook: Late January Volatility
As of January 18, we are looking at a high of 61°F today, which feels great until you see the low of 23°F coming tonight. That’s a nearly 40-degree swing. If you're planning your week, keep the heavy coat handy for Monday, January 19, where the high struggles to reach 52°F.
The real mess starts around January 21. We’ve got a system pulling in that brings a 40% chance of rain during the day, followed by a potential mix of rain and snow by January 27. Now, before you run to Kroger and buy all the bread and milk, let’s be real. In Fort Worth, "snow" usually means a few wet flakes that melt before they hit the pavement. However, the overnight lows will hover around 31°F to 32°F, meaning black ice on the overpasses is the actual threat you should worry about.

What February Has in Store
Looking deeper into the 30 day weather forecast for fort worth tx, February 2026 is shaping up to be a month of extremes. Historically, February is when the "Big Cold" likes to visit.
Data from the Climate Prediction Center suggests we are transitioning out of a La Niña phase into ENSO-neutral conditions. What does that mean for your weekend plans at the Stockyards? Basically, the jet stream is going to be wavy. We are likely to see "Arctic Clippers"—fast-moving cold fronts that drop the temperature 30 degrees in three hours.
- Early February (Feb 1-7): Expect a "Very Cold" turn. While January might end with heavy rain (there's a significant signal for storms around Jan 30-31), early February often sees the trailing edge of that moisture turn into a chill that sticks to your bones.
- Mid-February (Feb 14-21): There’s a trend toward "Sunny and Warm" days. We could easily see highs bouncing back into the upper 60s. This is that classic Texas "False Spring" that tricks the Bradford Pears into blooming way too early.
- Late February: The models show a return to "Chilly and Rainy" conditions, specifically for the northern parts of the Metroplex.
Why the 30-Day Outlook is Never "Set in Stone"
A lot of people check their phone apps and see a sun icon three weeks out and assume they’re good for a patio lunch. Don't do that. Long-range forecasting in Tarrant County relies on "Teleconnections"—large-scale atmospheric patterns like the Madden-Julian Oscillation (MJO).
When the MJO is in a certain phase, it can pump tropical moisture into Texas, leading to those weirdly humid, 70-degree January days. When it shifts, it opens the door for the Canadian air to slide down I-35. The 2026 winter has been dominated by these oscillations, making the 30 day weather forecast for fort worth tx more of a "likelihood" than a promise.
Humidity and Wind: The Fort Worth Special
Temperature is only half the story. In January and February, Fort Worth averages a relative humidity of about 70%. That’s a "wet cold." It’s the kind of weather that makes 45°F feel like 30°F because the moisture in the air pulls the heat right off your skin.
Also, watch the wind. We are looking at average speeds of 11 to 15 mph this month, with gusts frequently hitting 30+ mph during frontal passages. If you have patio furniture that isn't weighed down, it might end up in your neighbor’s pool by next Tuesday.

Actionable Prep for the Next 30 Days
- The 24-Hour Rule: Only trust the forecast for the next 24 hours. Anything beyond 7 days is just an educated guess based on historical analogs.
- Drip the Faucets: We have several nights coming up (Jan 18, 25, and 27) where lows dip into the 20s. If you live in an older pier-and-beam house in the Fairmount area, don't risk the pipes.
- Automotive Check: Battery failure is the #1 cause of winter breakdowns in North Texas. If your battery is more than three years old, that Jan 25 cold snap might be the day it finally gives up the ghost.
- Plant Protection: If you were tempted by the warm New Year and planted early, get your frost cloth ready for the week of January 26.
The next 30 days in Fort Worth will be a rollercoaster. You'll need a parka on Monday and maybe just a light hoodie by Thursday. It's frustrating, sure, but hey—at least it’s not boring. Keep your eyes on the radar as we approach the end of the month, especially around January 30, as that heavy rain signal looks like it could produce some localized flooding.
