Expect scattered showers and thunderstorms. Overall chances and coverage increase across the Brazos Valley late.

Locally heavy rainfall could result in minor flooding. The greatest risk of flooding will remain over the far western counties and Brazos Valley. Let's keep an eye on coastal locations this weekend.

Scattered showers and thunderstorms, more numerous across western parts of the region.

The rainfall threat continues through the weekend and into the start of the work week. On Thursday-Friday, the main threat remains in portions of the Brazos Valley. On Saturday-Monday, the main threat will be along the coast.

High rain chances will continue across SE TX through the weekend as deep moisture remains in place and a slow moving front crosses the region. Slightly cooler and drier weather are expected early to mid next week behind the front.
