602 FXUS64 KHGX 101811 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 111 PM CDT Fri Oct 10 2025 ...New DISCUSSION, MARINE... .KEY MESSAGES... Issued at 1234 PM CDT Fri Oct 10 2025 - Increased risk of fires through Saturday with low humidities in place. - Coastal Flood Advisory this evening for the Barrier Island due to above normal water levels. - No rain in the forecast through the next several days. && .DISCUSSION... Issued at 1234 PM CDT Fri Oct 10 2025 Mid-upper level high pressure over Mexico and Texas will continue to be the dominant weather feature, resulting in very low chances for rain over Southeast Texas through the next several days. The high temperatures over the weekend will generally be in the upper 80s to lower 90s inland and in the mid to upper 80s along the coasts. The lows tonight and Sunday night will be in the upper 50s to lower 60s over the Brazos Valley and Piney Woods region, the lower to mid 60s for the rest of the inland areas, and in the upper 60s to lower 70s along the coasts. Drier air will continue to filter in from the northeast tonight into Saturday, giving us dew points in the lower 50s to lower 60s throughout the weekend...perfect for an evening sunset or an early morning sunrise stroll. But be aware that low moisture levels will also lead to an elevated risk for fires. By Tuesday, mid level heights will rise to 590-593 dams while sunny skies persist, leading to warmer temperatures. The highs Tuesday into Thursday are expected to increase back into the lower 90s for much of the inland areas and in the upper 80s over the coasts, which is roughly between 6 and 11 degrees above normal for most of Southeast Texas. Global models are hinting at a closed upper level low moving into the Texas coastline from the Gulf sometime late Thursday into Friday. This feature would weaken the mid to upper level ridge, however, is it uncertain as to whether or not it will bring us any chance for rain. At this time the NBM is keeping Southeast Texas fairly dry Thursday and Friday...but conditions may change as we near the end of next week. Fingers crossed for some rain :). Cotto && .AVIATION...

Light onshore flow is expected Sunday into Monday, but northeast to east winds return Tuesday and continue into Thursday. There is a very low chance for rain through the next several days.
