...New SHORT TERM, LONG TER
Marine
.KEY MESSAGES... - A Flash Flood watch remains in effect for lower Southeast TX and South Central LA until 7PM tonight where periods of training precipitation over well saturated soils are likely to occur

- A Marginal risk of excessive rainfall has been outlined across across the forecast area through tonight.

- High rain chances will persist into this weekend; slightly lower chances early to mid next week

.SHORT TERM... (Tonight through Monday night) Issued at 228pm CDT Sat Jun 14 2025

The ongoing unstable pattern persists, with an upper-level trough situated over the central Gulf Coast. At the surface, high pressure in the Atlantic extends ridging across the Gulf, continuing to push a warm, moist air mass into the region. Tonight and into Sunday, the upper-level trough will shift southward and deepen; however, its influence on our area will be minimal. With reduced upper-level support, the risk of flash flooding and severe weather will be limited. But with CAPE values remaining in the 1000 to 1500 J/kg range thunderstorms will be possible with some stronger thunderstorms as a possibility. Otherwise the weather will begin to look like a typical summertime conditions will prevail, with afternoon showers and thunderstorms expected to continue through the weekend and into next week.

Temperatures will remain close to seasonal averages, hovering around 90 degrees, accompanied by high humidity. Heat index values are beginning to rise, with apparent temperatures projected to reach the triple digits on Sunday and Monday.

Long Term
(Tuesday through next Friday) Issued at 228pm CDT Sat Jun 14 2025

The remainder of the forecast resembles the start, with the existing synoptic setup persisting through midweek. Daily rainfall probabilities will remain in the 50–60% range, with air mass showers and thunderstorms developing each afternoon. By midweek, the pattern will begin to shift as the trough finally exits the region. Meanwhile, ridging in the Gulf will continue to support warm air advection, with dew points holding steady in the mid-to- upper 70s. As ridging builds overhead, rain chances will gradually decrease but will still remain in the 40–50% range.

Heat will become an increasing concern, with temperatures reaching the low to mid 90s when combined with dew points in the mid 70s we will start to see heat index values rising close to 105°F.

Marine
Issued at 228pm CDT Sat Jun 14 2025

Light to moderate onshore flow will continue for the next several days. Combined seas are between 1 and 3 feet are will be steady for the next several days. The main concern will be local impacts from showers and thunderstorms, primary in the afternoon.
