169 FXUS64 KBRO 110524 AAA AFDBRO Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1224 AM CDT Sat Oct 11 2025 ...New AVIATION... .DISCUSSION... Issued at 1015 PM CDT Fri Oct 10 2025 After several days of isolated to scattered showers/thunderstorms, a much more tranquil weather pattern will become established and persist. This will be due to 500 mb high pressure, the center of which will ease northeast from Mexico to the Lone Star State, but remain the dominant weather feature over Deep South Texas and the Rio Grande Valley. Dry weather is anticipated for the BRO CWFA for the vast majority of the period. However, a shot of convection is forecast for Tuesday, as a burst of deeper tropical moisture moves from the southeast out of the Bay of Campeche and western Gulf of America. Temperature-wise, although no extreme values are forecast, daytime highs and overnight lows will run above normal for this time of year. Finally, at the local beaches, an elevated risk of rip currents is likely through at least the middle of the new work week next week. && .AVIATION... (06Z TAFS) Issued at 1216 AM CDT Sat Oct 11 2025 VFR conditions are expected to continue over the cycle, with light and variable winds becoming primarily north-northeasterly Saturday morning. There is a low (less than 20%) chance of shallow ground fog development at all sites prior to sunrise with light winds. && .MARINE... Issued at 1015 PM CDT Fri Oct 10 2025 Light to moderate winds and low to moderate seas are expected along the Lower Texas Coast throughout the period courtesy of persistent high pressure over the western Gulf of America. Small Craft Should Exercise Caution and Small Craft Advisory are not likely to be needed. && .PRELIMINARY POINT TEMPS/POPS...
