- Slight Risk for Excessive Rainfall over northern portions of the region today - A Marginal Risk for Excessive Rainfall Thursday across western- most counties

DISCUSSION

Issued at 250 PM CDT Wed Jul 15 2026

A quasi-stationary mid-level low remains parked over Central Texas, where is continues to interact with deep Gulf moisture and produce widespread showers and thunderstorms capable of very high rainfall rates. This pattern has repeatedly affected portions of South- Central Texas over the past several days. The Uvalde area has been especially hard hit with multiple rounds of storms dumping 10+ inches at a time, resulting in catastrophic flooding.

Across South Texas, just south of the center of the low, conditions have been considerably quieter, with much lighter rainfall observed so far. The primary concern today remains with the potential for isolated weak low-level rotation, which could briefly produce a few water or landspouts.

The flood threat has not ended, particularly across our northern counties. As long as the aforementioned low remains nearly stationary, periods of heavy rainfall will remain possible, and the risk for both flash flooding and river flooding will continue.

Fortunately, by Thursday the low is expected to shift farther west while high pressure builds in from the east. This will promote a drier airmass across South Texas as mid- and upper-level winds shift more south to southwesterly.

From Friday into early next week, a much quieter and drier weather pattern is expected. Partly cloudy skies and gradually building heat will dominate the forecast.

AVIATION

(00Z TAFS) Issued at 631 PM CDT Wed Jul 15 2026

Some periods of MVFR conditions will be expected this evening through tomorrow morning at a few sites (ALI,COT,LRD). Combination of overcast skies and showers and thunderstorms will be the cause of these conditions. VFR conditions will return by Thursday afternoon. Gusty condtions will exist by early to mid morning Thursday with gusts around 20 to 25 knots.

MARINE

Issued at 250 PM CDT Wed Jul 15 2026

A Moderate to Fresh (BF 4-5) onshore flow through the period becoming more southerly early next week with some periods of a Light to Gentle breeze. The abundant moisture and current instability of the atmosphere has led to some water spouts being reported. Please use caution and avoid this dangerous hazard. This should diminish along with chances of precipitation over the waters as we head towards the end of the week. Low chances around 25% or less expected tomorrow and even lower this weekend.
