253 FXUS64 KHGX 071643 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1143 AM CDT Tue Oct 7 2025 ...New DISCUSSION, MARINE... .KEY MESSAGES... Issued at 1135 AM CDT Mon Oct 6 2025 - Isolated showers and storms will be possible along the coast and in the Gulf waters through the next several days - Hazardous marine conditions possible Wednesday night through Friday - Dry conditions Friday into Saturday may lead to increased fire weather potential. Please exercise caution when working with open flames/equipment that can cause sparks, especially in dry spots. && .DISCUSSION... Issued at 1041 AM CDT Tue Oct 7 2025 Other than a few isolated afternoon showers and storms along the coast over the next few days, we will remain rain-free through this upcoming week as an upper level ridge of high pressure builds over Texas. The rising heights and dry weather will lead to above normal temperatures with afternoon high temperatures rising into the low to mid-90s through Wednesday. Mild and muggy overnight conditions continue with lows generally in the low to mid-70s. A weak boundary will push into the area from the northeast Thursday into Friday ushering in slightly cooler, but much drier conditions. Daytime temperatures will cool a few degrees (highs generally in the upper 80s to low 90s), but overnight temperatures will drop into the low to mid-60s for much of the area with spots in the Brazos Valley and Piney Woods down into the upper 50s. The drier conditions but still warm afternoon temperatures will lead to afternoon relative humidity to drop into the 20-30% range for areas north of I-10. Winds will be light enough to limit fire danger somewhat, but the low RH values and dry vegetation may lead to fast fire starts. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 624 AM CDT Tue Oct 7 2025 Generally VFR, with spots of patchy fog out and about, transiently impacting TAF sites but most significantly LBX. Have mentions at those sites for the first 2-3 hours, but should be VFR area-wide shortly after sunrise. Winds fairly light today - generally following the same pattern of the last few days, but perhaps more variable since we`ll struggle to rise much above 5 knots even in the afternoon. Iso SHRA/TSRA should be anticipated again, but hold off on even any PROB30s. If anywhere, would anticipate LBX/SGR/HOU would have slightly better odds than elsewhere. && .MARINE... Issued at 1041 AM CDT Tue Oct 7 2025 Light easterly to northeasterly winds and low seas will prevail through Wednesday. An increase in the northeasterly winds will begin Wednesday Night, up to around 15-25kt, and persist through Friday causing seas to build to 4-6ft. Small Craft Advisories are likely needed during this timeframe. The increase in onshore winds and high astronomical tides will lead to higher than normal water-levels in the Bays and higher than normal tides along Gulf-facing beaches. Guidance currently has high tides up to around 3.5-4.0ft above Mean Low Low Water beginning Thursday. Fowler && .PRELIMINARY POINT TEMPS/POPS...
