KEY MESSAGES

Updated at 1214 PM CDT Thu Jun 25 2026 * Warm and generally dry conditions continue into next week, with a Moderate (level 2 of 4) Heat Risk each day.

* There is a Moderate Risk of life-threatening rip and longshore currents at area beaches.

DISCUSSION

Issued at 1214 PM CDT Thu Jun 25 2026

The 500mb ridge gradually works east across Texas this weekend and towards the Great Lakes by mid next week. This will maintain warm, but seasonal temperatures, into the start of July and slowly start to re-introduce a low chance of rain into late next week, mainly along the coast or sea breeze, as easterly flow increases moisture under the ridge. Expect breezy southeasterly winds each afternoon, especially Friday through Monday where gusts may approach 30 mph each day.

There is a Moderate (level 2 of 4) Heat Risk every afternoon, otherwise, the main hazard through the period will be life- threatening rip and longshore currents along the coast, potentially strengthening by mid-next week due to persistent easterly long period swell.

AVIATION

(18Z TAFS) Issued at 1214 PM CDT Thu Jun 25 2026

Mainly VFR conditions are expected to prevail through the TAF period with breezy southeasterly winds this afternoon and again Friday afternoon. Brief MVFR ceilings are possible late tonight into early Friday morning with anything streaming inland from the Gulf.

MARINE

Issued at 1214 PM CDT Thu Jun 25 2026

Increased southeasterly winds due to the strengthening pressure gradient along the lower Texas coast will drive Small Craft Caution to borderline Small Craft Advisory conditions, mainly along the bay, and gradually build Gulf seas towards 4 to 6 feet. There is a low chance of streamer showers or isolated thunderstorms, especially by mid to late next week.
