Synopsis - High pressure over the gulf will maintain moderate to fresh southeasterly winds and moderate seas through the period. Enhanced winds over the laguna madre are likely to result in rounds of small craft exercise caution (scec) headlines each afternoon and evening. Scec is possible across all coastal waters towards the end of this weekend and the beginning of next week as the pressure gradient begins to tighten.

Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 616 PM CDT Thu Apr 24 2025
New AVIATION
SHORT TERM
(Tonight through Friday night)
Issued at 106 PM CDT Thu Apr 24 2025
Upper level ridging looks to build across the Southern Plains through the short term period, support broad subsidence across the area. Sustained southeasterly low level flow will continue to advect warm and humid air to the region. This pattern will allow for increased cloud cover overnight tonight and Friday night as overnight cooling and light to moderate winds support the development of some low stratus. Cloud cover is expected to dissipate during the day Friday, with mostly sunny skies Friday afternoon. Rain chances are expected to remain near zero through the period. Low temperatures are expected to be in the low to mid 70s tonight and Friday night, while high temperatures Friday afternoon are expected to reach the upper 80s to low 90s.
LONG TERM
(Saturday through next Thursday)
Issued at 106 PM CDT Thu Apr 24 2025
The subtropical ridge gradually drifts south into mid next week as multiple troughs swing into the Southern Plains. This will maintain southwesterly flow aloft and generally dry conditions across Deep South Texas through Tuesday, with near to slightly above normal temperatures. Shortwaves Wednesday and Thursday enhance lift and instability, bringing a low 20 percent chance of thunderstorms, mainly across the northern ranchlands. Expect breezy to windy conditions each afternoon.
AVIATION
(00Z TAFS)
Issued at 607 PM CDT Thu Apr 24 2025
Mainly VFR conditions should transition to MVFR a few hours following sunrise this evening as ceilings lower at all TAF sites.
Brief periods of MVFR/lower ceilings are likely to persist at KBRO leading up to sunset. Overnight, winds weaken and ceilings gradually lower, but likely to remain MVFR. Following sunrise Friday morning, ridging aloft should lead to more scattered, broken at times, VFR conditions as southeasterly to southerly winds increase to 10-15 knots with gusts to 20-25 knots.
MARINE
Issued at 106 PM CDT Thu Apr 24 2025
Tonight through Friday night...Generally favorable marine conditions are expected through much of the period, however Small Craft Should Exercise caution headlines may be needed for the Laguna Madre this evening. Wind speeds are expected to decrease overnight, though they may briefly exceed 15 kts over portions of the Laguna Madre Friday, possibly requiring additional Small Craft Should Exercise Caution headlines.
Saturday through Thursday...Moderate to fresh southeasterly winds continue into late next week, with SCEC conditions likely across the bay nearly every afternoon. Seas are expected to gradually build, reaching SCEC conditions next week.
