FXUS64 KHGX 050645 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1245 AM CST Mon Jan 5 2026 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Abnormally low water levels during low tide in Galveston Bay will continue through Monday night with levels moderating closer to normal by mid-week. - Patchy to areas of fog possible nightly through midweek. - Warming weather the next few days with temperatures back into the 80s by midweek. Cold front on Friday ushers in cooler weather this weekend. && .DISCUSSION... Issued at 1035 PM CST Sun Jan 4 2026 Fall-like weather returns through Thursday thanks to southerly flow at the surface bringing warm, moist air in from the Gulf and weak ridging building aloft. High temperatures on Monday will be in the mid to upper 70s for much of the area, then increase to low to mid 80s Tuesday and Wednesday, and then potentially a could degrees cooler (but still in the upper 70s to low 80s) on Thursday thanks to increased cloudy cover. Overnight temperatures will be similarly unseasonably warm with lows generally in the 60s Monday night through Thursday night. There will also be a chance of nightly patchy fog developing through midweek as well. One thing to be on the look out for in the next few days will be an approaching boundary from the northwest on Tuesday that will be the difference between afternoon RH values in the 50s vs values in the 30s. The most likely scenario is that this boundary stalls north of our area keeping our entire region humid, but it could wobble a little further southeast into the northern Piney Woods and Brazos Valley region bringing those lower humidity values there. However, even if it does, this boundary quickly retreats back north by Wednesday. An upper-level disturbance will be swinging through the Desert Southwest on Thursday with the associated cold front moving through SE Texas on Friday. Increasing PVA and moisture will lead to scattered showers developing on Thursday, and then an increase in coverage on Friday ahead of and along the cold front. At this point its looking like the eastern half of the area (and into Louisiana) will have higher coverage and better chances of thunderstorms as the front taps into the Gulf moisture. A return to cooler (near normal) temperatures is then expected this weekend following the cold front's passage. Fowler && .AVIATION... (00Z TAF Issuance) Issued at 538 PM CST Sun Jan 4 2026 VFR conditions and SE winds at 5-10 KTS through early tonight. Winds will relax to 5 KTS or less overnight and cigs will lower down to IFR-MVFR. Vis could also lower to similar minimums over most sites as fog develops over the region. By around 15Z, winds will increase to 5-10 KTS, fog will gradually burn off, and cigs will lift and scatter out during the afternoon to evening hours. Similar conditions are expected Mon night into early Tue morning. Cotto && .MARINE... Issued at 1035 PM CST Sun Jan 4 2026 The main forecast concern the next few days will be the chance of fog developing nightly. Chances tonight into Monday morning will be highest in the northern parts of the Bays where fog may spill over from the land. More traditional sea fog becomes more likely in the Bays and nearshore waters Monday night and Tuesday night. Increasing winds and SSTs will lead to lower chances Wednesday night. Light onshore winds around 10kt will continue through Wednesday with southerly winds increasing to near 20kt Wednesday night into Thursday ahead of our next approaching cold front. This front will move through the coastal waters on Friday and usher in strong northerly winds late Friday and into the weekend. Scattered showers and isolated thunderstorms will be possible Thursday and Friday ahead of and along the cold front. A Low Water Advisory remains in effect Monday in Galveston Bay as water-levels drop down to near -0.8 to -1.0ft MLLW during low tide. Fowler && .PRELIMINARY POINT TEMPS/POPS...
