Random, pop-up downpours can be expected over the weekend, especially during the afternoon hours but coverage will be limited. Most of them will be brief but could still drop 1″ or so of rain. The only threat is lightning if you happen to be outside and a downpour hits your location. It stays hot & humid.
Isolated showers are possible Saturday, and additional rain chances take of Sunday evening. (Copyright 2026 by KSAT - All rights reserved.)
MONDAY
A front will give lift to a saturated airmass over South Texas. Downpours will focus along the boundary as it slowly shifts south across the region Monday afternoon into Monday evening. With heavy rainfall a possibility, there will be concern for street flooding.
The exact timing of rain for your neighborhood remains uncertain, so check back for updates. This is likely to be a slow moving front, and hasn’t even formed to our north yet, but in the days ahead, we will be able to get more specific with timing of rainfall. Regardless, drought-denting rain is likely for many neighborhoods.
