From Near-Record Heat to Freeze Watch: Central Texas Faces One of Spring’s Wildest 48-Hour Weather Swings
If you spent Saturday afternoon sweating in short sleeves, you weren’t imagining things — and you aren’t going to believe what’s coming.
Central Texas is about to experience one of the most dramatic 48-hour weather reversals the region sees in a typical year. Temperatures today will surge toward record-territory highs, with Austin flirting with 95 degrees — summer-worthy heat for the middle of March. By Monday, forecasters expect the high to struggle to reach the mid-50s. That’s a swing of roughly 40 degrees in a single day, and it’s being driven by a powerful cold front that’s already rewriting the week’s forecast.
The mechanism is a strong upper-level storm system pushing east across the Plains, dragging a cold front southward through Texas this afternoon and evening. A strong upper-level storm system moving across the Plains is driving a powerful cold front south through Texas, with north wind gusts potentially reaching 40 to 50 mph behind the front. For the Austin metro, winds are expected to shift northerly and rapidly increase to 20 to 35 mph with gusts to 45 to 55 mph, with poor overnight recovery as humidity rises only to the 25 to 35 percent range by Monday morning, then falls to 10 to 20 percent in the afternoon.
That combination of extreme wind and brutally low humidity is exactly what fire weather is made of.
Red Flag Country
The National Weather Service office in Austin/San Antonio isn’t mincing words. A Red Flag Warning is in effect for all of South-Central Texas from Sunday afternoon through Monday evening, covering Travis, Hays, Williamson, Bastrop, Caldwell, and more than two dozen surrounding counties. Forecasters warn that any fire that develops will catch and spread rapidly, and outdoor burning is not recommended.
…RED FLAG WARNING REMAINS IN EFFECT FROM NOON TODAY TO 8 PM CDT MONDAY FOR WIND AND LOW RELATIVE HUMIDITY FOR ALL OF SOUTH- CENTRAL TEXAS…
- AFFECTED AREA…All of South-Central Texas.
- TIMING…From noon today to 8 PM CDT Monday.
- WINDS…West at 10 to 20 mph with gusts to 30 mph through early afternoon before shifting north 20 to 35 mph with gusts of 45 to 55 mph late this afternoon through Sunday night.
- RELATIVE HUMIDITY…10 to 20 percent this afternoon and again Monday afternoon. Poor overnight recovery with the humidity rising only to near the 25 to 35 percent range.
- IMPACTS…Any fire that develops will catch and spread rapidly. Outdoor burning is not recommended.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
A Red Flag Warning means that critical fire weather conditions are either occurring now….or will shortly. A combination of strong winds…low relative humidity…and warm temperatures can contribute to extreme fire behavior.
Critical fire weather is expected to develop today and last into Monday, driven by a dryline and strong cold front bringing very low humidity and powerful winds. Even after temperatures drop tonight, dry conditions and strong winds will keep fire danger dangerously high through Monday.
…WIND ADVISORY REMAINS IN EFFECT FROM 3 PM THIS AFTERNOON TO 5 AM CDT MONDAY…
- WHAT…North winds 20 to 35 mph with gusts of 45 to 55 mph expected. Highest gusts may focus over the higher terrain in the Hill Country and Southern Edwards Plateau after sunset.
- WHERE…All of South Central Texas
- WHEN…From 3 PM this afternoon to 5 AM CDT Monday.
- IMPACTS…Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.
We're tracking very hot temperatures Sunday ahead of the front, but these wind gusts behind the front should be of bigger concern, as tree limbs falling on power lines due to the winds causing power outages, as well as extreme fire danger due to this and the low humidity. @KVUE pic.twitter.com/cyQylVJpih

The window of concern is not brief. Even as temperatures plunge overnight tonight into Monday — with Monday morning lows in the 30s and 40s and cold wind chills — the fire danger remains elevated into Monday evening. Hill Country residents should be especially alert, as a light freeze is possible there, with some colder pockets along and east of I-35 potentially dipping near freezing.
Anyone with outdoor equipment, burn piles, or open flame sources of any kind should plan to keep them completely idle through at least Tuesday.
What’s Behind the Extremes?
Texas weather has a well-earned reputation for volatility — the old saying about waiting five minutes for the weather to change holds especially true in spring. But the broader pattern shaping this week is worth understanding.
The state has been operating under the influence of a La Niña climate pattern that kept the jet stream pushed north and away from Texas for most of the past winter, generally meaning less rainfall and warmer temperatures than normal. During La Niña, the weather-making jet stream is pushed north and away from Texas, usually resulting in less rain than average, especially in winter. That helps explain why much of Central Texas has been drier than usual heading into spring, which in turn is a major reason why fire risk amplifies so dramatically when a wind event like this one rolls through — the fuels are primed.
The good news, at least in the big picture: La Niña appears to be fading.
Climate forecasters expect a transition from La Niña to ENSO-neutral in the next month, with ENSO-neutral favored through May through July 2026. Beyond that, there is a 62% chance that El Niño will emerge during June through August 2026, according to NOAA’s Climate Prediction Center.
El Niño on the Horizon — But No Guarantees
An El Niño pattern typically tilts the odds in favor of wetter conditions across the Southern United States. A shift to El Niño dips the jet stream and pulls more Pacific moisture into the southern portion of the U.S., which can bring more rain. For drought-weary Central Texas, that sounds like relief — and it may well be. But climate scientists are urging caution about expecting too much too soon.
The American Southwest and Southern Plains have been in drought for nearly six years, leaving reservoirs, streamflow, and aquifers significantly depleted — conditions that would require more than one wet year to meaningfully reverse. Climatologists also note that a brief El Niño cycle from mid-2023 into early 2024 delivered some rain relief to parts of Texas without eliminating drought conditions.
The ENSO transition also carries implications for severe weather. Historical analysis indicates that La Niña events transitioning toward El Niño during the spring have increased the frequency of severe weather, particularly across Kansas, Oklahoma, and Texas. In short, wetter doesn’t always mean calmer — it can mean a more active severe weather season as the atmospheric pattern reorganizes itself.
Looking Ahead
For now, the immediate concern is fire safety through Monday evening. Once the Red Flag Warning lifts, Central Texans can expect a brief cool stretch before temperatures rebound. Long-range forecasts suggest well above-average temperatures returning across much of Texas from March 17 through March 21, with rainfall chances remaining limited.
The larger story of spring 2026 is still being written. Whether the ENSO transition delivers meaningful drought relief to the Highland Lakes and the aquifers feeding the region’s water supply remains one of the most important weather questions of the year. For now, stay aware of fire conditions through Monday, keep an eye on wind advisories, and hold off on any burning until forecasters give the all-clear.
