FXUS64 KHGX 041126 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 526 AM CST Sun Jan 4 2026 ...New AVIATION... .KEY MESSAGES... - Abnormally low water levels during low tide in Galveston Bay will continue through Sunday with levels moderating closer to normal through the first half of next week. Continued low water is likely due to the very low astronomical tides occurring. - Patchy to areas of fog possible nightly beginning Sunday night through midweek. - Warming trend begins on Monday with temperatures back into the 80s by midweek. Cold front on Friday ushers in cooler weather next weekend. && .DISCUSSION... Issued at 1014 PM CST Sat Jan 3 2026 Some slightly cooler weather will remain in place over SE Texas this weekend following Saturday morning's weak cold front. And even though temperatures will be cooler, it will still be about 10 degrees above normal. Temperatures will drop into the 40s before dawn Sunday morning, then rise into the mid 60s to low 70s during the day on Sunday. Southerly winds redevelop by Sunday night with ridging building overhead leading to warming weather through midweek. High temperatures on Monday will be in the mid to upper 70s, then low to mid-80s Tuesday and Wednesday. Warm and humid weather is expected to continue into Thursday, especially for the southern half of the area, but there will be more uncertainty as an upper level-low and cold front approaches from the west. This disturbance will move through the area either late Thursday night or Friday bringing a chance of showers/storms and a return to cooler weather for next weekend. Other than the warm weather through midweek, we will be on the lookout for patchy fog developing nightly beginning on Sunday night. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 522 AM CST Sun Jan 4 2026 An MVFR cloud deck in our southern zones and patchy dense fog in our northern zones should dissipate by mid-morning. However, areas near the coast may remain MVFR well into the morning, possibly until midday. VFR conditions expected to prevail this afternoon as light winds veer southeast. Rising moisture levels this evening into tonight will result in an increased risk of lower cigs/vis, especially after 0800 UTC. There is high confidence that flight conditions will drop to at least MVFR in most locations overnight. But there is also a growing risk of IFR and even LIFT conditions as well. && .MARINE... Issued at 1014 PM CST Sat Jan 3 2026 Northeasterly winds around 10-15kt will continue through Sunday morning, becoming light easterly then southeasterly Sunday afternoon into Sunday night. Light onshore winds and low seas will then prevail through at least midweek. The onshore winds will bring a chance of patchy sea fog nightly beginning Sunday night. The chance of fog midweek will be conditional as warming SSTs should limit the fog potential. Abnormally low water levels during low tide will continue on Sunday with water levels getting down to around -1.0ft MLLW at low tide in Galveston Bay. Low tides will continue to remain on the lower side going into the work week, but will be less significant thanks to decreasing astronomical tides and onshore winds (-0.8ft MLLW on Monday, -0.5ft MLLW on Tuesday, near 0.0ft MLLw on Wednesday, etc.).
