KEY MESSAGES

Updated at 542 AM CDT Sat May 9 2026

- A quieter and drier pattern is expected through most of the remainder of the weekend before another cold front late Sunday into early Monday

- A few thunderstorms could become locally strong Monday depending on available instability and shear, although current guidance suggests limited severe potential

- Cooler temperatures behind the front will keep highs mainly in the 80s Monday/Tuesday, followed by a gradual warming trend

DISCUSSION

Issued at 123 AM CDT Sat May 9 2026

Shower and thunderstorm chances early this morning will gradually taper off throughout the day. A drier pattern is then expected to settle across South Texas through the remainder of the weekend before rain chances increase late Sunday into early Monday. Attention turns to the next cold front that is expected to push through the region late Sunday night into early Monday. Increasing mid-level support associated with a shortwave moving southeast across Texas combined with modest upper-level support tied to a strong low north of the Great Lakes region, will bring low to medium chances for showers and thunderstorms along and ahead of the boundary.

While a few strong thunderstorms are possible, confidence in severe weather is limited at this time. Current model guidance indicates relatively weak deep-layer shear, with the GEFS mean bulk shear values generally around 20-30 knots. Rainfall amounts with FROPA are 0.25" or less for most locations.

Behind the front, cooler and drier air will filter into South Texas, keeping daytime highs mainly in the 80s Monday and Tuesday. A warming trend will allow daytime highs to rebound into the mid 80s to mid 90s throughout the region by mid-week and persist for the rest of the forecast period. Overnight lows behind the front will fall from the 70s into the 60s across much of the area. Skies will remain partly cloudy overall, with periods of increasing cloudiness during the overnight hours.

AVIATION

(12Z TAFS) Issued at 542 AM CDT Sat May 9 2026

Ongoing showers and thunderstorms will continue through around 15Z this morning, ending from west to east. MVFR/VFR ceilings prevail this morning for all but VCT where LIFR ceilings and visibility have developed. Expect all terminals will be VFR by 16Z with light winds. Clouds will move in again tonight resulting in MVFR ceilings around 06Z.

MARINE

Issued at 123 AM CDT Sat May 9 2026

A gentle to occasionally moderate southeasterly breeze (BF 3-4) will persist through Sunday. Winds will shift northeast early Monday behind a cold front, briefly increasing to moderate levels before weakening again Monday night. Low rain chances (20-35%) will continue through Saturday morning, with another round of showers and thunderstorms possible Sunday night into Monday morning. Otherwise, marine conditions are expected to remain fairly benign through the period.
