DISCUSSION

Issued at 143 AM CDT Wed May 27 2026

Convection will persist overnight with conditions beginning to improve by Wednesday midday as another round pushes eastward from Mexico during the early morning hours. Strong to severe thunderstorms capable of producing damaging winds and hail will persist through this period. Already a large swatch of 1-3 inches of rainfall and more to come, warrants a Flood Watch for the southern Brush Country and portions of the Coastal Bend.

A slight chance for showers and thunderstorms will continue through the day thanks to lingering moisture and the sea breeze. Expect a ridge to begin building in the region by Thursday allowing for generally warmer and drier conditions.

Chances for showers and storms will return to the region this weekend as the ridge weakens allowing for shortwaves to creep into the region. Chances remain low at this time, though it will be something to watch in future forecast packages. Highs will be in the 80s and 90s through next week.

AVIATION

(12Z TAFS) Issued at 627 AM CDT Wed May 27 2026

Showers and thunderstorms continue this morning, with some strong to severe storms finally nearing the coast. Expect thunderstorms to weaken, but continue through around 16Z. Showers may continue through 18Z with chances decreasing this afternoon and evening. MVFR/IFR conditions are expected this morning, particularly in and around any heavy showers or thunderstorms. VFR conditions will develop this afternoon.

MARINE

Issued at 143 AM CDT Wed May 27 2026

Moderate to Fresh (BF 4-5) E-SE winds will prevail today. Light to Gentle (BF 2-3) SE winds will then prevail Thursday through Saturday. There is a high (60-70%) chance of thunderstorms through this morning bringing periods of gusty and erratic winds and locally elevated seas.

HYDROLOGY

Issued at 143 AM CDT Wed May 27 2026

An estimated widespread 0.5" to 2.0" of rain has fallen already early this morning. Another round of showers and storms are lining up east-west across the southern Brush Country into Coastal Bend, capable of producing a few more inches of rain. Due to the primed soils and lower flash flood guidance, a Flood Watch is now in effect for the aforementioned region through this morning. Remember, 'turn around, don't drown.'
