KEY MESSAGES

Updated at 159 PM CDT Tue Jul 14 2026

- Scattered thunderstorms Wednesday with high rainfall rates could lead to some localized flash flooding.

- Heavy rainfall upstream could lead to significant river flooding along the Rio Grande near Laredo.

- Temperatures increase as the region dries out Friday into the weekend.

DISCUSSION

Issued at 159 PM CDT Tue Jul 14 2026

Ample moisture remains in place across the region, and while all forcing is north of the area this afternoon (leading to significant flooding west of San Antonio), by tonight a boundary will sag south into the area and we will see an uptick in PoPs to 50-60%, especially north. Any convection that does move into/develop in our area will be able to produce locally heavy downpours with rainfall rates of 1 to 3 inches per hour.

While area wide rainfall totals are generally low, under half an inch, they do peak a bit higher in the Cotulla area. Probabilities of an inch or more of rain are up to near 50% for around Cotulla, and much lower for most of the area. Uncertainty remains high where any heavy rain may potentially fall, so no flood watch has been issued, with one exception, and that is along the Rio Grande near Laredo. See the hydrology section below for more information.

By Thursday into Friday, mid level forcing pushes to the west and relatively drier deep layer air settles in lowering rain chances. Just an isolated sea breeze shower/storm would be in the forecast from Thursday night into the weekend. Temperatures early in the period will be a few degrees below normal, then return to near normal levels by the weekend.

AVIATION

(18Z TAFS) Issued at 159 PM CDT Tue Jul 14 2026

Convection continues off to our north, but is staying away from area terminals. VFR conditions now will become a mixture of MVFR and VFR conditions overnight. Rain chances will increase late tonight into tomorrow afternoon as the boundary slides south, so have included the potential for showers and thunderstorms at VCT and COT. There is high uncertainty regarding any rain potential at other terminals at this time.

MARINE

Issued at 159 PM CDT Tue Jul 14 2026

Generally gentle to moderate (BF 3-4) southeasterly-southerly winds with seas running 2 to 3 ft should persist through mid-week. Winds become more moderate to fresh beyond Wednesday with seas increasing to 4-5 ft. Generally low to medium (25 to 40 percent) rain chances are expected through early Thursday.

HYDROLOGY

Issued at 159 PM CDT Tue Jul 14 2026

Heavy rainfall upstream from Laredo over the next couple days along the Rio Grande could lead to significant flooding, particularly along the Rio Grande at Laredo. This largely hinges on exactly where the heaviest rain falls, so for now we have opted to issue a River Flood Watch for the Rio Grande at Columbia Bridge and Laredo.

As we watch upstream gauges and where the heaviest rain falls, flood warnings will be issued as needed. Stay tuned to the latest forecast if you live anywhere along the Rio Grande.
