DISCUSSION

Issued at 1206 PM CDT Wed Oct 21 2026

Mainly quiet weather will continue across South Texas this week. A weak disturbance over the western Gulf will bring a chance for showers, and possibly a thunderstorm, tonight over the coast and coastal waters. This feature will move inland to the southwest Thursday with a low chance for showers across the southern portion of the CWA. A mid to upper level ridge will build over the region during the end of the week keeping the weather dry through the weekend. Temperatures will continue to be just a bit above normal with highs in the 80s. Low temperatures Thursday morning will be a few degrees warmer than the last couple of days with more cloudiness from the westward moving disturbance. Clearer skies will allow for cooler mornings over the weekend. Another weak disturbance from the Gulf will bring a chance for rain next Monday with better chances over the Coastal Plains. Tuesday models are showing a frontal boundary moving through North Texas with an expansive area of rain across the eastern half of the state. Still a lot of uncertainty.

Guidance continues to show elevated tidal levels and the potential for minor coastal flooding continues through the week.

AVIATION

(00Z TAFS) Issued at 724 PM CDT Wed Oct 21 2026

Mainly VFR/MVFR conditions flip back and forth during this TAF period as showers move across the region due to a weak low in the Gulf. Terminals like CRP, ALI, and LRD will mainly see this with PROB30s showing up early tomorrow morning as well. VCT can see IFR conditions due to low visibility early to late tomorrow morning but become VFR shortly after. LIFR conditions appear in LRD early tomorrow morning due to extremely low ceilings. All sites generally expected to return to VFR tomorrow afternoon. Winds across all terminals are shifting from east to southeasterly flow and remaining light through the TAF period except for in and around storms.

MARINE

Issued at 1206 PM CDT Wed Oct 21 2026

Mainly a gentle to moderate easterly flow can be expected through the period with winds shifting more onshore by this weekend. A moderate to high rain chance will continue tonight. Additional rain chances will return next Monday.

FIRE WEATHER

Issued at 1206 PM CDT Wed Oct 21 2026

Near to slightly above normal temperatures will continue across South Texas through much of the forecast period, with highs generally ranging from the low to upper 80s through the end of the week then temperatures gradually cool by a few degrees as we head into the middle of next week. Atmospheric moisture will generally keep minimum RH values above critical thresholds across most
