San Antonio weather: scattered storms return before dry weekend
Scattered storms are bubbling up across San Antonio again, with KSAT reporting isolated pop-up showers and possible lightning through about 9 p.m. on August 28. The brief rain ends a dry streak, but high pressure returns for a hot, mostly dry weekend with highs near 100°F before cooler days arrive next week. Central Texas forecasters say widely scattered activity marks one more round of spotty rain before the weekend settles into a hotter, drier pattern.
KXAN meteorologists described widely scattered storms bubbling up again across the region as August drew to a close, offering one more round of spotty rain before the weekend. KSAT's Weather Authority team noted that San Antonio's rain-free streak had ended, raising the question of whether more showers could follow on Friday.
Key Takeaways
- Isolated pop-up showers and thunderstorms were possible through about 9 p.m. on August 28, with lightning and thunder in some areas.
- High pressure returns this weekend, pushing rain chances down and keeping daytime highs near 100°F on Saturday and Sunday.
- Small, isolated showers may return Saturday and early next week, but forecasters expect a stretch without triple-digit heat.

- Axios San Antonio published a reader poll asking how residents feel about the city's summer heat as temperatures stay elevated.
What ended San Antonio's dry streak?
KSAT reported that San Antonio's extended rain-free run had finally broken, with stray showers moving through the area on August 28. Some storms carried lightning and thunder, though coverage remained isolated rather than widespread.
Meteorologists emphasized that these were pop-up showers—brief, scattered cells rather than a soaking front. That pattern aligned with KXAN's forecast of one more round of spotty rain before conditions turned drier.
Will San Antonio see more rain this weekend?
After Friday evening's isolated activity, the weekend outlook turns hot and dry. KSAT forecasters said high pressure would make a brief return, removing most rain chances while pushing highs into the upper 90s on Saturday and Sunday, near 100°F.
Small, isolated showers could still appear Saturday and during the start of next week. Forecasters noted they were happy to finally see a week without 100-degree temperatures on the horizon—a shift that matters for residents who have endured a punishing summer.
How are San Antonians feeling about the heat?
As storms offered only brief relief, Axios San Antonio published a poll asking readers how they feel about the San Antonio heat. The survey landed amid a summer when triple-digit days have stacked up and outdoor plans often hinge on timing around the hottest hours.
The poll reflects growing local attention to heat's toll on daily life—from commuting in scorching cars to scheduling pool visits and evening outings. For more on how technology and data are reshaping how communities track extreme weather, see our Future Tech & AI Wonders coverage hub.
What's happening with Tropical Storm Dolly?
While Central Texas dealt with scattered showers, KSAT tracked Tropical Storm Dolly in the Atlantic. The system formed recently but was gradually falling apart, with remnants expected to dissipate by Saturday.
Dolly posed no direct threat to South Texas, leaving local attention on homegrown pop-up storms and the return of dry, hot weekend weather. For official regional forecasts and advisories, check the National Weather Service Austin/San Antonio office.
