307 FXUS64 KBRO 102316 AAA AFDBRO Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 616 PM CDT Thu Jul 10 2025 ...New AVIATION... .DISCUSSION... Issued at 1205 PM CDT Thu Jul 10 2025 Low rain chances (less than 20%) are expected for the duration of the forecast period with the greatest chances of rain over the Gulf waters or just right along the coast. The limited chances of rain are due to the presence of Saharan dust over the region along with a surface high pressure. However some rogue showers are possible with the seabreeze during the afternoons each day thanks to the daytime heating. As for the temperatures, the highs are generally expected to remain in the 90s for each day, however a few places in Starr and Zapata could get into the triple digits. Due to the previously mentioned Saharan dust in the region, the air should be drier limiting the heat indices to a range of 105-108. Thus the heat risk for most of the period is expected to be Moderate at the greatest. The overnight low temperatures are expected to remain in the 70s with some places approaching 80. Lastly, for the beaches, with the period and wave heights increasing slightly to 6 seconds and 3 to 4 feet, a moderate risk of rip currents is likely to be needed for the next several days at the Lower Texas coastal beaches. && .AVIATION...
