Texas Storms Thursday: Is San Antonio in the Crosshairs?
Texas Weather Watch: Heat, Humidity, and a Tropical Update
Hey there! Think of this like your friendly neighborhood weather report, but explained simply—like we’re chatting over a glass of iced tea. Let’s break down what’s happening with the Texas weather and the tropics this week.
Why Has It Been So Dry?
Imagine a big, heavy blanket of air sitting over Texas. That’s basically what high atmospheric pressure does—it pushes air down, warming it up and squeezing out the moisture.
Important Point: Through the first 12 days of August, cities like San Antonio, Austin, and Dallas haven’t seen a single drop of measurable rain. That’s a very dry start to the month!
What’s Changing on Thursday?
The high pressure is finally sliding a little to the east. This small move might let some Pacific moisture sneak in, bringing a chance of rain—but mostly for West Texas.
Thursday in San Antonio: Step by Step
| Time | What to Expect |
|---|---|
| Early Morning (before 9 AM) | Mostly cloudy, temps near 80°F |
| Late Morning | Clouds clear out, sun takes over |
| Noon | Temperature climbs to lower 90s |
| Late Afternoon | Upper 90s to near 100°F |
But Wait—It Feels Even Hotter!
Important Point: Heat Index = Temperature + Humidity. It’s what your body actually feels.
- Actual temp: ~100°F
- Heat index: 103°F to 107°F
- That’s dangerous heat territory. Stay hydrated, limit outdoor time, and check on neighbors!
Wind Alert
- Breezy conditions all day
- Evening gusts over 25 mph possible
Where Will the Storms Be?
Best chances = West Texas only.
| Area | Storm Potential |
|---|---|
| Big Bend | High |
| Davis Mountains | High |
| Midland / Odessa / Lubbock | High |
| Rest of Texas (including San Antonio) | Dry |
Heads up: Any storms in West Texas could pack strong winds and frequent lightning.
Friday: A Tiny Taste of Moisture
A small surge of Gulf moisture drifts north Friday. Here’s the rain breakdown:
Rain Chances by City
| Location | Rain Chance | Details |
|---|---|---|
| Corpus Christi, Victoria, Galveston, Houston | 20–30% | Scattered showers & storms possible |
| San Antonio metro | Only 10% | Maybe one isolated shower |
| San Antonio skies | — | More clouds → temps drop a couple degrees |
Weekend Outlook: Hello Again, Heat
| Day | High Temp | Heat Index | Morning Low |
|---|---|---|---|
| Saturday | ~98–99°F | ~105°F | Upper 70s |
| Sunday | ~98–99°F | ~105°F | Upper 70s |
Important Point: The heat isn’t going anywhere. Plan outdoor activities for early morning or evening. Drink water before you’re thirsty!
Tropics Update: Meet Cristobal & Friends
Tropical Storm Cristobal
- Formed: Wednesday in the central North Atlantic
- Status: Short-lived—expected to dissipate Thursday as it moves east
- Threat to Texas: None
Two Disturbances to Watch
Both are in the mid-Atlantic, moving west.
| Disturbance | Development Chance | Timeline | Possible Name | Potential Impact |
|---|---|---|---|---|
| Westernmost | 80% | Next 2 days | Tropical Storm Dolly | Could reach eastern Caribbean by weekend |
| Eastern one | Lower (not specified) | Coming days | — | Too early to tell |
Important Point: Neither system threatens Texas right now. But we’ll keep watching!

FAQ: Your Questions Answered
1. What exactly is "heat index"?
Think of it as the "feels-like" temperature. When humidity is high, sweat doesn’t evaporate well, so your body can’t cool down. A 100°F day with high humidity can feel like 107°F. That’s the heat index.
2. Why does high pressure mean no rain?
High pressure = sinking air. Sinking air warms up and dries out. Clouds and rain need rising air. So that "blanket" of high pressure basically puts a lid on rain chances.
3. Should I worry about Tropical Storm Cristobal?
Nope! It’s way out in the Atlantic, moving away from land, and falling apart. Zero threat to Texas.
4. What’s a "tropical disturbance"?
It’s a cluster of thunderstorms in the tropics that might organize into a tropical depression or storm. Think of it as a "storm seed." The one with 80% chance? That seed is sprouting fast.
5. When will this heat wave end?
The article doesn’t say—but the pattern (high pressure, Gulf moisture trying to sneak in) suggests more of the same for now. Keep checking local forecasts for updates!
Stay cool, stay safe, and keep an eye on the forecast!
