KEY MESSAGES

Updated at 202 AM CDT Tue Jun 9 2026

- Isolated seabreeze showers/storms in the afternoons with a Moderate to Major HeatRisk (levels 2/3 of 4) through the weekend

- Increased rain chances this weekend along with increased surf conditions/potential for minor coastal flooding

DISCUSSION

Issued at 202 AM CDT Tue Jun 9 2026

Mid-level high pressure increases across South Texas while generally keeping surface moisture pumping into the area thanks to the persistent onshore flow. This increases the heat index values across the region back into the 100-110F range. A Moderate HeatRisk (level 2 of 4) will be widespread across South Texas meaning those sensitive to heat, especially those without cooling/hydration, would be greatest at risk. In the locations that see the greatest opportunity of clearer skies and more opportunity to raise the thermometer even further will see brief periods of Major Risk (level 3 of 4) which would leave all people without cooling/hydration at risk. The seabreeze will do its part to spark up some showers and thunderstorms, but these will be isolated in spatial coverage and weak/short-lived in nature with low-end chances of occurring (10- 20% chances).

This weekend, additional plumes of tropical moisture will traverse the region around the Tehuantepec Isthmus/Yucatan Peninsula. At the same time, a low pressure system drops a front into Red River Valley. While the front will stall out closer to the Dallas Metroplex, the added moisture from the Gulf and surface convergence may be enough to allow more widespread showers associated with the seabreeze or storms that move inland. Confidence in exact amounts or timing is low right now but we will continue to monitor the trends.

We continue to monitor this weekend's surf conditions given the persistent southeasterly moderate to fresh breezes (BF 4-5), increased swell period, and the approach of next week's new moon will lead to increased rip current risk and the potential for minor coastal flooding. For those from out of the town (or any international visitors), take plenty of hydration/shade breaks, if going to the beach, have a plan to quickly escape a seabreeze storm, follow all beach hazard flags, and reapply sunscreen/mosquito repellent!

AVIATION

(06Z TAFS) Issued at 1241 AM CDT Tue Jun 9 2026

Expecting MVFR CIGs across all terminals except VCT overnight tonight. VCT is expected to remain FEW to SCT. Generally not expecting fog as winds will be a limiting factor but have maintained it in PROB30s as it remains possible. May amend TAFs if fog becomes more predominant. Winds generally southeast to more easterly at times with gusts persisting this upcoming afternoon into the overnight hours mainly across western terminals.

MARINE

Issued at 202 AM CDT Tue Jun 9 2026

Expect moderate to fresh (BF 4-5) southeasterly winds with 3-4 seas through Thursday. Low end showers mainly will be for inland locations, though the bays and nearshore waters will still have the potential for a few to move through this week. From Friday, seas increase to 4-6 ft for the weekend with increased chances of showers and thunderstorms across the western Gulf.

FIRE WEATHER

Issued at 202 AM CDT Tue Jun 9 2026

Rain chances through the week will be on the low end (10-15%) associated with any seabreeze that moves through, though the chance for wetting rain remains low. The recent green-up along with minimum relative humidity values remaining above 40% will keep the fire risk low.
