Marine Weather and Tide Forecast for Groves, TX

DISCUSSION
(Tonight through next Saturday)
Issued at 926 PM CDT Sat Jul 11 2026

It was a muggy night across southeast Texas and much of Louisiana.
Temperatures were holding steady in the low 80s with dew points running the mid to upper 70s. Showers and thunderstorms were numerous today, however, all activity was waning off for the exception of a couple of off shore showers.

A large summertime high was centered over the Mountain West while an areas of upper level weakness was positioned across the deep south. Deep tropical moisture continues to advect onshore underneath the upper weakness. This pattern will offer daily rounds of showers and thunderstorms. The frequency of this activity will be unusually high for typical pulse thunderstorm afternoons. Therefore, isolated areas of flash flooding will be possible on a daily basis through at least Tuesday afternoon.
Cloud cover and rain will keep temperatures in check, generally experiencing highs in the mid to upper 80s.

As we advance into the Wednesday - Friday time frame, both the AI GFS and ECMWF are suggesting high pressure to evolve somewhere over the south central part of the conus. If this materializes, rain chances will decrease and afternoon temperatures should increase into the 90s. I still believe slow moving storms that develop will produce high rain rates in short periods of time that will bring a risk for flash flooding.

AVIATION
(00Z TAFS)
Issued at 926 PM CDT Sat Jul 11 2026

Pilots flying in and out of the southeast Texas and southwest Louisiana airports can expect mostly VFR conditions this evening and overnight. Numerous showers and thunderstorms impacted the region today, however, that activity was quickly fading and will lead to a mostly dry and tranquil night.

A large upper level weakness across the deep south will force another round of daytime showers and thunderstorms tomorrow (Sunday). Thunderstorms will once again be numerous, beginning in the mid to late morning, and continuing through the afternoon hours. Some of these storms will need to be closely watched for downburst activity.

There continues to be a signal for some light fog up across central Louisiana early Sunday morning. This could bring some MVFR fog to the Alexandria airport for a few hours in the morning.

Safe Travels.

MARINE
Issued at 926 PM CDT Sat Jul 11 2026

Off shore convection will persist through at least Tuesday and maybe beyond as tropical moisture remains trapped underneath a broad area of upper level weakness.

Wind speeds across the marine zones will be consistent ranging from 0 to 10 knots over the next 7 days. Wave heights will remain below 3 to 4 ft due to weak winds across the northern Gulf.
Localized wave heights could be higher near stronger thunderstorms.

FIRE WEATHER
Issued at 926 PM CDT Sat Jul 11 2026

There are no concerns for fire weather conditions that would create a rapid spread in wildland fires.

Vegetation across southeast Texas and much of Louisiana has experienced healthy rainfall to maintain moist fuels.

Humidity levels will remain high and chances favor low wind speeds over the next few days. Localized higher wind speeds will be possible near stronger thunderstorms.

Look for numerous showers and thunderstorms on a daily basis through at least Tuesday afternoon.
