Houston weather: Scattered showers possible this weekend, some areas under heat advisory

Published August 15, 2026 8:58 AM CDT

It stays very humid across Southeast Texas for the next several days, with scattered showers possible throughout the weekend, but clearing out by Monday. 

Not everyone will get rain, but a passing pop-up could bring a quick sense of relief for those areas.

Dangerous triple-digit heat possible

A stretch of hotter and generally drier weather develops, with afternoon highs pushing into the upper 90s and the humidity making it feel even hotter in the triple digits. 

Some counties just north of the immediate Houston area are under a heat advisory until 8 p.m. on Monday, including Nacogdoches, Shelby and Angelina counties, amongst several others.

Tropical waves show little organization

We’re still watching a couple of tropical waves across the Atlantic, but neither looks particularly impressive right now. 

They are battling wind shear & dry air limiting development. Neither system is expected to pose a threat to Texas.
 

Tropical storm Lala is expected to become a hurricane soon and hit parts of Hawaii over the weekend. Expect the threat of flooding, strong winds and big waves.
