KEY MESSAGES

Updated at 127 PM CDT Sun Jul 19 2026

- While we are seeing some flood waters receding, we are still seeing some elevated levels in the Nueces, Frio, San Antonio and Rio Grande basins. Avoid flooded areas.

- More seasonal July heat and humidity will continue to settle into the region, with a continued dry pattern expected to persist through the first half of next week.

- Monitoring Tropical Depression Two over the northeastern Gulf, which is expected to track westward towards the upper or middle Texas coast by Thursday or Friday.

SHORT TERM

(Tonight through Monday night) Issued at 127 PM CDT Sun Jul 19 2026

River flooding is expected to continue across a few areas along the Nueces, Frio, San Antonio, and Rio Grande basins over the next few days as runoff continues downstream. General improvement is expected, but we are monitoring the potential for an additional rise along the Nueces River near Asherton on Monday. Impacts should be limited to areas mainly right along the riverbank.

Ridging aloft will support seasonably hot and rain-free conditions across South Central Texas as subsidence increases. Expect highs mostly in the 90s, with a few areas approaching the triple digits across the Rio Grande Plains and Coastal Plains. In combination with the humidity, expect heat index values in the upper 90s to around 103 degrees Monday afternoon. If spending any time outdoors during the afternoon hours, continue to take frequent breaks in the shade and stay hydrated.

LONG TERM

(Tuesday through next Sunday) Issued at 127 PM CDT Sun Jul 19 2026

South Central Texas will remain under the influence of subtropical ridging aloft through at least the first half of the week, which will maintain a typical summertime pattern for mid July with minimal rain chances. High temperatures will gradually increase into the mid to upper 90s by Wednesday, with a few areas across Central Texas reaching the triple digits. Afternoon dew points may need to be adjusted over the next few days, which may bring us closer to Heat Advisory criteria by mid to late week.

Meanwhile, well be keeping an eye on the tropics over the next few days as Tropical Depression 2, currently centered over the northeastern Gulf, translates westward toward the mid/upper Texas Coast. Isolated showers cannot be ruled out, mainly along and east of the I-35 corridor, as moisture content increases Thursday and Friday. There remains uncertainty on the exact track and evolution of this system as it tracks westward, and it is too early to determine what, if any, impacts may occur across South Central Texas late this week and into the weekend. Continue to check back for updates and have trusted sources of information.

AVIATION

(18Z TAFS) Issued at 127 PM CDT Sun Jul 19 2026

VFR conditions will hold at all terminals through 08Z with possible IFR/MVFR cigs at KAUS. There is a possibility of low CIGs at the remaining terminals, but confidence is too low to put it in the forecast. VFR will return tomorrow around 12Z. Otherwise, winds will remain S-SE 5-10 kts.
