...UPDATED National Weather Service Brownsville TX
620pm CDT Monday September 25 2023

Long Term
(Wednesday through next Monday) Issued at 249pm CDT Monday September 25 2023

A westward shift in the persistent mid/upper level ridge over Northern Mexico will open the door (or at least a small window) to daily precipitation chances across portions of Deep South Texas through the end of the week, possibly into the weekend. While most of this activity will be associated with the sea breeze, the aforementioned weak frontal boundary associated with Tuesday's convection will linger through the period and act an additional source of lift for isolated to widely scattered showers and thunderstorms. The highest Probability of Precipitation (around 30-40 percent) will reside along and east of US-281 and over the Gulf waters, but isolated convection over the Rio Grande Plains cannot be ruled out especially with any residual boundaries over the region. Locally heavy rain, frequent lightning, and gusty winds cannot be ruled out with any stronger thunderstorms. Precip chances look to decrease heading into the weekend as ridging builds overhead.

Otherwise, slightly above normal temperatures are expected with highs in the upper 90s to around 100 degrees. Heat indices should remain below Heat Advisory criteria despite slightly higher dew points as the influence of the ridge remains to our west.

Marine
Issued at 249pm CDT Monday September 25 2023

Now through Tuesday night...Light to moderate winds and low to moderate seas will be expected to persist over the Lower Texas coastal waters as the pressure gradient stays quite relaxed with the approach of a pre-frontal trough and/or front from the north from the overnight through Tuesday. These boundaries are to yield to a northerly wind shift and opportunities of isolated to scattered showers and thunderstorms. Winds and seas may become higher in and around thunderstorms.

Wednesday through Sunday...Light to moderate east to southeast winds and low to moderate seas. Isolated to scattered showers and thunderstorms will be possible each day. Light to moderate onshore flow and wave heigheights between 2 to 3 feet, with 3 to 4 feet possible by the weekend.
