FXUS64 KHGX 021109 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 509 AM CST Tue Dec 2 2025 ...New AVIATION... .KEY MESSAGES... - Gusty northerly winds and elevated seas will lead to hazardous marine conditions through Tuesday afternoon. - Chillier weather will persist through Wednesday with overnight lows in the 30s to lower 40s with portions of the Piney Woods possibly dropping to near freezing. - Rain chances return Wednesday night through Friday morning due to another coastal low and incoming cold front with the greatest coverage of the showers and isolated thunderstorms likely remaining along the coast. && .DISCUSSION... Issued at 1005 PM CST Mon Dec 1 2025 After Monday's departing system to the east, we will be experiencing a fairly chilly night across SE Texas with low temperatures dropping into the mid to upper 30s across most of the area (and even some spots in the Piney Woods dropping to near freezing). Tuesday will be on the cooler side again with highs only in the low to mid 50s as a surface high pressure settles in over the area, but it will feel better than today with most sunny skies. With clear skies and light winds, Tuesday night will be another chilly one with temperatures similar to tonight, albeit possible a degree or two warmer. That high pressure moves on to the east on Wednesday ushering in a southerly flow allowing for high temperatures to climb into the mid 60s to low 70s across the area. Increasing moisture from the southerly flow and passing shortwaves in the southwesterly flow aloft will lead to an increase in shower activity Wednesday night through at least Friday morning. Lingering shower activity may linger through the day on Friday. It will be a similar set- up to Monday's event with widespread light to moderate rainfall with isolated thunderstorms. WPC does include an area of Marginal Risk (level 1 of 4) for excessive rainfall along the northern portions of the coast on Thursday. Most likely impact would be some minor flooding of low lying, poor drainage areas. A cold front will push through late Friday into Saturday ushering in a return to cooler and drier conditions through the weekend. As of now, it will likely not be as cold as Monday-Tuesday, but low temperatures back into the 30s-40s will be possible over the weekend. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 509 AM CST Tue Dec 2 2025 Lingering MVFR ceilings across parts of the metro and coastal areas will lift/scatter out in the next couple hours leaving prevailing VFR conditions for the remainder of the day. Moderate north winds early this morning will diminish as the day progresses...eventually veering to the ESE-SE overnight. 47 && .MARINE... Issued at 1005 PM CST Mon Dec 1 2025 Hazardous marine conditions are expected through at least the first half of Tuesday as strong north to northeasterly winds develop behind a departing coastal low. Winds along the coast have already climbed to sustained 20-25kt with gusts to 30-35kt, and these conditions are likely to continue through Tuesday morning along the immediate coast, and through Tuesday afternoon along the offshore waters. Rough bay waters and seas of 5-8ft are expected during this time as well. Due to these conditions a Small Craft Advisory is in effect through Tuesday morning along the coast, and then into Tuesday afternoon in the offshore waters. Abnormally low tides are expected Tuesday morning (around 0.0 to 0.5ft below MLLW), and a low water advisory may be needed in future updates. Conditions will improve Tuesday night into Wednesday with light to occasionally moderate east to southeasterly winds. Another approaching upper-level disturbance will bring increasing chances of widespread showers and isolated thunderstorms Wednesday night through Friday evening. A coastal low is expected to develop on Thursday inducing moderate to strong northeasterly winds Thursday morning through Friday morning. Fowler && .PRELIMINARY POINT TEMPS/POPS...
