DISCUSSION

Issued at 119 AM CDT Mon May 25 2026

Weak upper level ridging today will limit convective development, but can not rule out an isolated storm or two along the sea breeze. Most locations will remain rain free along with partly cloudy skies and slightly warmer temperatures.

The ridge shifts east Tuesday and embedded mid level short waves begin tracking east and northeast across TX. Moisture is forecast to deepen Tuesday into Wednesday with PWATs increasing to 2.0-2.2 inches, especially the eastern portions of S TX. The environment is progged to be unstable, along with strong low level moisture convergence, increasing upper diffluence. Combined with the short waves aloft, these features will be conducive for thunderstorm development. Chances are medium to high (50-90%) mainly Tuesday night and Wednesday with rain chances tapering off Wednesday night into Thursday from west to east. Rain chances will be low to very low by the end of the week and into the weekend as ridging aloft takes hold. This will also lead to a warming trend with temperatures going from slightly below normal to slightly above normal by the end of the week.

AVIATION

(12Z TAFS) Issued at 555 AM CDT Mon May 25 2026

Patchy fog inland over the Coastal Plains is impacting ALI/VCT, along with a mix of MVFR/IFR ceilings. Lower ceilings have been noted over the southern Brush Country making it northwards towards ALI. Only expecting these deteriorated conditions to continue over the next couple of hours before VFR conditions prevail by 15-16Z across South Texas. Winds will remain light at around 10 knots or less shifting northeast to southeast through the day. Another low ceiling and patchy fog threat inland over the Coastal Plains is in store near the end of the forecast.
