Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 1210pm CDT Sat April 19 2025 Long Term (Sunday Night through Friday) Issued at 313am CDT Sat April 19 2025 An active weather pattern continues to be anticipated during this portion of the total forecast. In the Sunday night through Monday time frame, a weak cold front will approach, stall, and dissipate within Deep South Texas and the Rio Grande Valley. This will then be followed by the approach and passage of a series of mid-level disturbances riding within a generally west to east 500 mb flow overhead. The cumulative effect of all of this will be a near-daily shot of isolated to scattered showers and thunderstorms across the BRO CWFA, with the best chance for precipitation forecast for Monday and Tuesday. Temperature-wise, above normal overnight lows and near to slightly above normal daytime highs are also anticipated, courtesy, in part, to a moderate to breezy generally onshore flow. Marine (Today through Sunday) Issued at 313am CDT Sat April 19 2025 Strong southeasterly winds are expected to continue through tonight, building seas to around 8 ft over the Gulf waters. Winds will decrease Sunday as a cold front moves into Deep South Texas, but likely stalls before reaching the coast. Seas will likely be slower to respond, gradually subsiding late Sunday afternoon. The Small Craft Advisory has been extended through Sunday evening. (Sunday Night through Friday) Small Craft Advisory conditions will likely continue along the Lower Texas Coast through Sunday night due to an enhanced pressure gradient. The approach, stall, and dissipation of a weak cold front around sunrise Monday will weaken the gradient at that time, allowing for more moderate marine conditions at that time and through Tuesday. However, the return of an enhanced pressure gradient Wednesday through Friday will result in Small Craft Should Exercise Caution to Small Craft Advisory conditions for that time period. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...High Rip Current Risk through Sunday evening for TXZ451-454-455. GM...Small Craft Advisory until 7pm CDT Sunday for GMZ130-132-135- 150-155-170-175. |
