FXUS64 KHGX 030648 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1248 AM CST Tue Nov 3 2026 ...New DISCUSSION, AVIATION, MARINE... .KEY MESSAGES... - Cold front, and thin band of showers and storms, passes across the region today. - Drier and seasonable weather tonight into Thursday. - Warm front briefly and associated scattered showers moves back inland Thursday, but another cold frontal passage is forecast Thursday night. && .DISCUSSION... Issued at 1247 AM CST Tue Nov 3 2026 Cold frontal boundary and associated thin band of showers and thunderstorms is currently tracking across northern and western Tx. This front and precipitation should be making its way into the Brazos Valley 5-7am, the US59/I69 corridor 1-4pm, and off the coast just before sunset. Instability-wise, things aren't overly impressive for a widespread severe wx threat. That said, we'll be keeping an eye out for an isolated strong to severe storm or two. Best upper diffluence should be situated across northern zones this morning and also east of the I-45 corridor into mid-late afternoon. We'll also monitor for any weak seabreeze/baybreeze that might try to develop prior to the fronts arrival that could briefly enhance some llvl convergence near the coast late in the day. Primary threat of any isolated strong cells would be 25-45mph wind gusts. Otherwise, look for decreasing cloudiness and a return to seasonable conditions tonight and Wednesday. The front will return north as a warm front late Wednesday night & Thursday bringing increasing cloudiness and possibly some scattered showers back into parts of the area as the day progresses. By Thursday evening, chances further increase (moreso I-10 southward) as moisture availability becomes better and we see another cold front move across the region during the overnight hours. Models aren't exactly on the same page in terms of the mid level pattern heading into the weekend. GFS indicates a quasi-zonal flow before ridging builds overhead. ECMWF/UKMET/ICON show we might see either a cutoff low and/or deepening trof across Mexico and southern Texas. Either way, seasonable wx probably won't be all that much different inland with temps close to normal and rain chances fairly low. Exception might be near the coast and in the Gulf water where POPs will be higher along with breezier winds/elevated seas. 47 && .AVIATION... (06Z TAF Issuance) Issued at 1247 AM CST Tue Nov 3 2026 MVFR level CIGS have begun to creep in, and should continue to fill in for the next couple of hours. Some sites may see temporary CIG degradations to LIFR and patchy fog may develop around sunrise. A cold front pushes southeast across the region tomorrow. Ahead of the front, showers/storms are expected to develop. These storms may cause reductions in visibility, produce frequent lightning, and occasional gusts. General timing from the latest guidance shows showers/storms arriving to KCLL early tomorrow morning, then to KIAH/KHOU late morning/early afternoon, and finally to KGLS by mid afternoon. As the front passes, winds veer from SSE to NNW. Cooler and drier air arrives behind the front, leading to VFR conditions after the front passes. MLG && .MARINE... Issued at 1247 AM CST Tue Nov 3 2026 Light to occasionally moderate south winds are expected into the afternoon. A cold front, and associated thin broken band of showers and thunderstorms, will push off the coast in the late afternoon and early evening hours. Northwest to north winds will increase behind the front, and a Small Craft Advisory may be required for a short time period tonight in the Gulf waters until speeds diminish Wednesday morning. Onshore flow will resume Wednesday night as the boundary moves back north as a warm front. Another cold front is forecast Thursday night. 47 && .PRELIMINARY POINT TEMPS/POPS...
