FXUS64 KHGX 122354 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 554 PM CST Mon Jan 12 2026 ...New AVIATION... .KEY MESSAGES... - Negative tide levels are anticipated in the bays this week, most significant late Wednesday-Thursday. - Increasing cloud cover tonight and Tuesday ahead of an upper disturbance. Rain chances low, but not exactly nil. - Two cold fronts are forecast to push through the area. One on Wednesday and another Friday night or Saturday. && .DISCUSSION... Issued at 101 PM CST Mon Jan 12 2026 Upper low near Baja will be kicking out and will move across the state Tuesday and Tuesday night. Main thing we'll see is increased mid-upper cloudiness, though we cannot completely rule out an isolated light rain shower or sprinkle. This system will pass to our east Tuesday night followed by decreasing cloudiness. Plenty of sun to start the day Wednesday, along with a sw/w llvl flow, should allow for a quick warm-up with temps topping out in the upper 60s-low 70s before the next front moves into the region during the late morning and afternoon hours. Cooler, dry wx is again expected Thursday...a bit warmer Fri...then another front Fri night or Sat. Dry nw flow aloft, with ridging to our west and trof to our east, should keep this fropa and weekend dry too. 47 && .AVIATION... (00Z TAF Issuance) Issued at 549 PM CST Mon Jan 12 2026 All sites at VFR with VFR prevailing through the period. BKN to OVC mid-high level clouds will continue through the period. NE winds will give way to more light and variable winds overnight. Winds will become SW inland during the day Tuesday. Bailey && .MARINE... Issued at 101 PM CST Mon Jan 12 2026 Mariners should anticipate negative tide levels through the week, especially around low tide cycles in the central and northern half of the the bays. Will maintain the Low Water Advisory in place...though values might fall just short of criteria (-1 MLLW) between nor an Tue. But with a Wednesday daytime frontal passage pushing additional water out of the bay, it'll probably be a no-brainer and mariners should be cognizant of grounding risks. Otherwise, light winds and low seas in place will build and SCAs look through Tuesday. The next front is expected to push into the waters Wednesday afternoon with increasing northwest and north winds filling in behind it Wednesday night into Thursday along with building seas. 47 && .PRELIMINARY POINT TEMPS/POPS...
