FXUS64 KHGX 091732 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1132 AM CST Mon Nov 9 2026 ...New AVIATION... .KEY MESSAGES... - Cloudy and cool for the next couple days with some chances of mainly light rain. - Cold front is expected Wednesday night followed by drier colder weather for the remainder of the week. && .DISCUSSION... Issued at 1203 AM CST Mon Nov 9 2026 Mid-upper low across northern Mexico will lift northeast and across the state Tuesday and Tuesday night. The next round of precipitation looks to expand across south Texas in the next several hours. This batch of rain should eventually track toward the Matagorda Bay region and our southwest counties toward sunrise...continuing enewd toward the I-45 corridor (generally Conroe to the coast heading into the mid morning and lunchtime hours). Until the upper trof axis pushes to our east, cloudy and cool conditions will persist into Tuesday. Impulses embedded in the flow aloft will intermittently track across the area and provide enough lift to produce some sprinkles or light rain at times. Better chances of accumulating rain, albeit light but much needed) should again be across southern and western portions of the CWA. (Higher pressure in the llvls from the ArkLatex area should sag swd will create less saturated moisture profiles closer to the surface...hence lower POPs across northern zones which'll be more prone to virga if anything). Toward midweek, we'll get into a drier nw flow aloft as western ridging makes its way toward the Rockies and a deeper trof digs across the eastern CONUS. Such a pattern will favor a cold frontal passage (probably late Wednesday night). It should be a dry fropa...followed by cooler temperatures filtering into the region Thurs-Sat. They'll be most noticeable at night with lows in the 40s. High pressure moves off to the east Saturday, followed by a gradual warming trend and a return of some rain chances early next week in advance of the next western trof. 47 && .AVIATION... (18Z TAF Issuance) Issued at 1132 AM CST Mon Nov 9 2026 SHRA continues to enter the region from the SW and persists until late this afternoon or early evening. Due to the SHRA beginning later then initially expected, lingering showers south of IAH until 22/23z cannot be ruled out. TS impacts remain low and out of TAFs, but an occasional rumble around Matagorda Bay remains possible. During this time, CIG/VIS reduction to MVFR or high end IFR remain the primary impacts, particularly for KSGR/KHOU/KLBX terminals. After the conclusion of SHRA, MVFR CIGS/VIS, due to patch fog, are anticipated to set in overnight and last through sunrise. During the entire TAF period winds are anticipated to remain out of the NNE around 5-7kts at all terminals minus GLS. GLS is anticipated to maintain a N-NE breeze around 5-10kts through the TAF cycle. CMW && .MARINE... Issued at 1203 AM CST Mon Nov 9 2026 East and northeast winds will diminish today as surface high pressure sinks into the region from the north and the pressure gradient weakens. Light winds and lower seas will then continue into midweek. Late Wednesday night and Thursday morning we should see our next cold front push into the coastal waters followed by moderate offshore winds and building seas. Small Craft Advisories appear likely in the wake of the front. Winds/seas begin to diminish on Friday, followed by a return of southerly winds late Saturday as high pressure pushes off to the east. 47 && .PRELIMINARY POINT TEMPS/POPS...
