FXUS64 KHGX 170534 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1234 AM CDT Sat Oct 17 2026 ...New DISCUSSION, AVIATION, MARINE... .KEY MESSAGES... - Cool and dry this weekend. - Hazardous marine conditions expected with elevated winds/seas today. Slowly improving conditions are anticipated later in the day into Sunday. - Warmer temperatures return next week, but just seasonable in nature. && .DISCUSSION... Issued at 1235 AM CDT Sat Oct 17 2026 Winds are still elevated behind the cold front, particularly over the Gulf waters and coast. As high pressure builds in the wake of FROPA, the surface pressure gradient loosens and the winds weaken this afternoon. The rest of the weekend is cool and dry, with highs in the upper 60s-low 70s, lows in the 40s/50s and low RH's. The approaching workweek is similarly temperate, with models largely in agreement. Surface high pressure transitions further to to our E bringing an easterly fetch of winds across our area for much of next week. This subtle difference from our typical SE flow is enough to stifle moisture development and rain chances and helping to keep PWATs around and below 1" for much of the region. The main concern for rain chances, albeit low, will be mostly offshore Monday-Wednesday. Without reprieve from rain (and only partly cloudy mid-upper levels), high temperatures gradually climb to the 80s by Wednesday, and lows in the mid 50s inland and upper 60s towards the coast. BSM && .AVIATION... (06Z TAF Issuance) Issued at 1235 AM CDT Sat Oct 17 2026 VFR conditions will prevail through the period with some sct/bkn high cloudiness streaming overhead. North winds have decreased across most inland locations, but remain windy along the coast. With some mixing after sunrise Saturday, suspect we'll see northerly winds increase again inland - not as highs as Friday, but some 20- 25kt gusts are possible. Heading into the afternoon, speeds will begin a downward trend...eventually becoming light toward sunset. 47 && .MARINE... Issued at 1235 AM CDT Sat Oct 17 2026 Winds behind the front are still strong over the bays and nearshore waters and a Gale Warning remains in effect through the morning hours. These winds are from the N between 25-30 kts, gusting up to 40 kts. Seas are between 5-12 ft and should gradually diminish later this afternoon into Sunday. Gales will probably transition to SCA's later today and possibly tonight offshore. A moderate easterly fetch sets up across the northern Gulf Coast for much of the work week. SCEC/SCA's may be required at times Mon-Wed in the offshore Gulf waters. BSM. && .PRELIMINARY POINT TEMPS/POPS...
