Well, folks, here we are — staring down Labor Day weekend with sweat on our brows and a complicated tropical story overhead. After one of the driest and hottest Augusts on record in Central Texas,[7] the atmosphere is finally stirring. The culprit — and unlikely savior — is Tropical Storm Edouard, or rather what’s left of it. Let’s break down what the next week holds for Austin, the Hill Country, San Marcos, Round Rock, and the rest of our corner of the Lone Star State.
Edouard’s Remnants: The Week’s Wild Card
Tropical Storm Edouard made landfall along the Texas coast and pushed inland, leaving a soggy trail across East Texas before its remnants began making a rather unusual U-turn back southward.[4] While our friends between Houston and Dallas are dealing with a very high flooding risk from the remnant low, the picture for Central Texas is considerably less dramatic — but still meaningful after such a brutal dry stretch.[4]
The remnant low has been increasing rain coverage across our region, with spotty storms possible in the late afternoon and early evening hours, and a potential line of storms sliding in from North Texas overnight.[4] The key caveat: by the time Edouard’s remnants reach Central Texas, the system will be significantly weaker and carrying far less moisture than what East Texas is experiencing. We are not looking at inches or feet of rainfall here.[4]
What we are looking at is the potential for tropical-style downpours in isolated pockets — the kind that can drop a half-inch to an inch of rain in a very short period of time.[4] The Weather Prediction Center placed areas just east of Austin under a Level 1 to 2 excessive rainfall risk earlier in the week, with the caveat that the heavy rainfall axis could shift westward into Central Texas proper.[6] The NWS Austin/San Antonio office noted that “the primary concern with any storms will be downbursts and locally heavy rainfall that could lead to localized and minor flooding issues.”[6]
Actionable takeaway: If you’re planning outdoor activities Thursday through Friday, keep a close eye on radar, especially if you’re east of I-35. That’s where the rain and storm chances are most concentrated. If you’re in the Hill Country or west of Austin, your odds of seeing meaningful rainfall are lower, but not zero — NWS forecasters noted isolated showers could arise across the Southern Edwards Plateau and the western Hill Country as well.[2]
Labor Day Weekend: Hot, Humid, and Mostly Dry
Let’s be honest: Labor Day weekend is not going to feel like fall. Not even close.
Saturday, September 5: Expect sunny and hot conditions, with high temperatures approaching but likely stopping just short of 100°F — the NWS pegs the daytime max around 99°F for Austin.[1] The real story, as always this summer, is the humidity. Atmospheric moisture will remain plentiful, and as southeast winds pick up through the afternoon, they’ll draw additional Gulf moisture into the region. That combination will push heat index values — the “feels like” number — as high as 106°F by mid-afternoon.[1] Saturday night brings more clouds and overnight lows staying stubbornly above 77°F.[1]
Sunday, September 6: More of the same. Temperatures in the upper 90s, Gulf moisture keeping the humidity oppressive, and mostly cloudy to partly sunny skies depending on how much cloud cover lingers from overnight.
Monday, September 7 (Labor Day): The holiday itself looks mostly sunny and hot, with daytime highs peaking at or near 100°F. Southwest winds of around 5 mph will shift to southeasterly by afternoon, and overnight lows will again stay warm, above 77°F.[1] Austin is unlikely to see much accumulated rainfall over the holiday weekend — the bulk of any precipitation will remain concentrated closer to Houston and East Texas through Tuesday morning.[1]
Actionable takeaway: If you’re planning a Labor Day cookout, pool party, or outdoor festival, plan to be outside in the morning hours and seek shade and air conditioning by early afternoon. Heat index values above 105°F are genuinely dangerous, especially for children, elderly residents, and anyone doing physical labor outdoors. Hydrate aggressively.
The Extended Outlook: Rain Chances Linger Into Next Week
Here’s a sliver of good news for the rain-starved: the NWS Austin/San Antonio office is forecasting a 15% to 45% chance of rain and storms from Friday night, September 4 through Wednesday, September 9, with the storm zone primarily running along and east of the I-35 corridor and extending through the coastal plains.[2] Any isolated heavier downpours, the NWS noted, “will be capable of producing an inch or little more in a short time.”[2]
Looking at KXAN’s extended 7-day forecast, temperatures through next Thursday remain stubbornly in the upper 90s, with highs ranging from 98°F to 99°F and overnight lows holding in the mid-70s.[3] The triple-digit streak may be technically broken by Edouard’s moisture and cloud cover, but make no mistake — this is not a cool front. It’s a brief interruption in an otherwise relentless pattern.
September’s Big Picture: Warmer Than Normal, But Rain Is Possible
KXAN’s meteorologists put it well: while August is typically Austin’s hottest month, temperatures normally drop fairly quickly as September progresses.[5] The Climate Prediction Center’s September outlook suggests near-normal rainfall odds for the month — which, given how catastrophically dry August was (measurable rainfall fell on just one day in Austin all month, August 27), would represent a significant improvement.[6] The temperature outlook, however, leans toward warmer-than-normal conditions continuing through September as a whole.[5]
In plain English: don’t put away the fans yet. But there is legitimate reason to believe the worst of the 2026 summer heat marathon may finally be entering its final miles.
The Bottom Line for Central Texas
Here’s your week at a glance:
- Thursday–Friday: Best rain chances of the stretch, courtesy of Edouard’s remnants. Isolated downpours possible, especially east of I-35. Marginal flood risk. Highs in the mid-to-upper 90s — a brief break from triple digits.
- Saturday–Monday (Labor Day weekend): Sunny, hot, and brutally humid. Highs 98–100°F, heat index up to 106°F. Minimal rain for Austin; better chances east toward Houston.
- Tuesday–Wednesday: Lingering storm chances (15–45%) along the I-35 corridor and eastward. Highs remain in the upper 90s.
- September overall: Near-normal rain odds (better than August’s near-zero), but temperatures stay above average for the month.
After weeks of writing about relentless heat and deepening drought, I’ll take even a modest tropical moisture infusion as a sign of progress. Stay cool, Central Texas — and if you hear thunder this weekend, don’t be surprised if it’s not coming from a football stadium.
