693 FXUS64 KHGX 282316 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 516 PM CST Sat Feb 28 2026 ...New AVIATION... .KEY MESSAGES... - Fog will remain a possibility nightly through the weekend, especially in the coastal areas. - Unseasonably warm weather will continue through the start of next week. - Few cold fronts will try but are unlikely to reach SE Texas next week. && .DISCUSSION... Issued at 1130 AM CST Sat Feb 28 2026 Onshore another warm day is in store for this afternoon. There's still a ~12F dewpoint gradient from north to south across SE Texas. Thus, RH values are expected to fall to generally 30-50% across inland areas and 50-80% near the coast. Highs should remain in the 70s/mid 80s with lows in the 50s/lower 60s. With onshore flow remaining in place and moisture poised to keep rising, sea fog will remain the primary hazard to focus on over the weekend, appearing in the bays/nearshore waters and coastline during the nighttime, then spreading inland and becoming more extensive during the early morning hours. Still, the broader extent and intensity of fog should wane heading into next week as waters slowly warm. We're still expecting a few shortwaves & disturbances to pass north of our area next week. First of these occurs on Monday, where a cold front attempts to scoot its way towards SE Texas, but stalls near north-central Texas. The next front should be approaching SE Texas around mid week on Wednesday, but it too is anticipated to stall out near the Red River Valley. Even without the front, deeper moisture and shortwave energy overhead may still bring some showers and storms across the area beginning around mid week. Yet another front will try to push towards the area on Friday, but even this one appears to stall before reaching SE Texas. LREF Ensembles back the deterministic models, still showing strong consensus on a southerly wind direction all through the upcoming work week. Cloud cover and showers may help shave off some of the heat, but warm weather will still dominate with highs in the 70s/mid 80s with lows in the 60s. 03 && .AVIATION... (00Z TAF Issuance) Issued at 516 PM CST Sat Feb 28 2026 Another round of MVFR/IFR ceilings and visibilities is expected later this evening into Sunday morning. Expect conditions to gradually deteriorate from south to north after 00Z-02Z. Dense fog is expected to be mainly an issue for terminals near and south of I-10. Reduced ceilings are anticipated areawide. There remains some uncertainty on how far northward the lowest visibilities will extend. Fog/low ceilings will lift after 15Z-16Z. Southeasterly winds around 8-12 kt will prevail throughout the day on Sunday with intermittent wind gusts around 20 kt in the afternoon. Expecting another round of reduced visibilities/ceilings Sunday night into Monday morning. Batiste && .MARINE... Issued at 1130 AM CST Sat Feb 28 2026 Some patchy fog may linger in the coastal waters during the afternoon hours. Cannot rule out additional extensions of the marine fog advisory if conditions do not improve. Another round of fog is anticipated tonight into Sunday morning. Fog may be patchier in nature compared to previous nights, though anticipate larger increases in coverage and intensity by early Sunday morning. Still, warming water temperatures should start to decrease the chances for sea fog Sunday night into Monday as waters warm. Otherwise, expect light winds and low seas will continue through at least mid week. 03 && .PRELIMINARY POINT TEMPS/POPS...
