.DISCUSSION...
Issued at 1005 PM CDT Thu Sep 18 2025
Daily rain chances are expected to continue into next week as
persistent tropical moisture remains in place across Deep South
Texas. A series of upper level disturbances and the daily
afternoon sea breeze will likely provide the forcing necessary to
support isolated to scattered showers and thunderstorms
periodically through the period.
Short term HiRes guidance depicts another round of convection
developing along the coast early Friday morning moving offshore
after sunrise. An additional round of convection will likely
develop late morning through the afternoon as the sea breeze front
moves inland. The best rain chances (30-50%) look be contained to
the Rio Grande Valley, with a 15-30% chance of rain across the
northern counties.
High temperatures look to remain in the 90s through the period,
with overnight lows largely remaining in the low to mid 70s.
Western portions of the CWA may see low temperatures dip into the
upper 60s tonight and Friday night.

(00Z TAFS)
Issued at 645 PM CDT Thu Sep 18 2025
Predominantly VFR conditions are expected to continue through the
period, though additional rounds of showers and thunderstorms may
briefly produce MVFR to IFR conditions. HiRes models depict
another round of isolated showers moving through the area
overnight. Overall, confidence is low for any of these showers
impacting a TAF site, though probabilities are slightly higher at
BRO. Isolated to scattered convection will become more likely
through the late morning and into the afternoon, though the
probability impacts at any of the airfields will still remain low.

.MARINE...
Issued at 1005 PM CDT Thu Sep 18 2025
Generally favorable marine conditions are expected to continue
through the period. Daily rain chances will persist through the
period, with isolated to scattered showers and thunderstorms
possible over the Gulf waters. Light to moderate onshore winds and
slight to moderate seas are expected to continue through the
period.
