FXUS64 KHGX 210025 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 625 PM CST Fri Feb 20 2026 ...New AVIATION... .KEY MESSAGES... - Areas of fog are expected once again this evening through Saturday morning. - Scattered showers expected today along with an uncertain temperature forecast due to the presence of a frontal boundary (see discussion). - Cold front pushes through the region Saturday, bringing cooler & drier weather Sunday and Monday, along with strong winds in the Gulf and bays. && .DISCUSSION... Issued at 1156 AM CST Fri Feb 20 2026 A stationary boundary is currently draped across northern portions of the CWA. Warm and humid conditions are expected to persist ahead of the boundary, with highs near 80 degrees across central and southern portions of the forecast area, while areas to the north may struggle to to warm beyond the upper 60s. Weak low-level lift along and just north of the boundary may support a low chance (20-40%) chance for scattered light showers. In addition widespread low-level moisture will continue to support periods of fog once again tonight into early Saturday prior to the frontal passage. The highest risk for dense fog will be across areas south of I-10 and coastal portions of the area. A stronger cold front is expected to move through Southeast Texas on Saturday. Behind the front, a reinforcing surge of high pressure will overspread the region, bringing a notable increase in northerly winds, a rapid drying trend, and decreasing temperatures by late afternoon and evening. High temperatures on Sunday and Monday are expected to generally be in the low-to-mid 60s, with lows reaching the upper 30s to mid-40s. By the middle of next week, the surface high shifts east and onshore flow redevelops, allowing the warmer and more humid conditions to return. && .AVIATION... (00Z TAF Issuance) Issued at 528 PM CST Fri Feb 20 2026 Tonight will be similar to last night with expanding IFR to LIFR conditions for much of the region. Currently, VFR conditions remain in place for much of the region with some few to scattered low clouds in place with ceilings around 5000-6000ft, with the exception of GLS where LIFR conditions remained through the day today. Expecting lowering ceilings to IFR conditions (around 600-800ft) between 3-5z for IAH southwards, then up through CXO and UTS by 6-9z. Conditions will crash down to LIFR conditions with CIGs near 200-400ft within an hour or two after dropping to IFR. Patchy, but dense, fog will also be a possibility through the night into the early morning hours of tomorrow. CLL may be able to stay at MVFR levels through the night, but a period of IFR conditions due to ceilings will be possible between 8-10z. A cold front is expected to pass through the area during the day on Saturday ushering in a northerly wind shift and gradually improving ceilings. There will be isolated light rain showers developing ahead of the front along the coast, but coverage will be limited enough to keep from putting in the TAFs. FROPA will happen at CLL around 10-13z, at IAH between 13-15z, and then off the coast by 15-18z. CIGs will improve to MVFR levels (around 1500ft) within 2-3 hours post front, and then to VFR level (few to scattered low clouds still possible, but mostly mid- level clouds remaining). Expecting VFR conditions returning to all of the area between 21-00z. Northwesterly winds around 10-15kt with gusts to 20-25kt are expected to develop during the afternoon hours across much of the region. The winds gusts should end by sunset for most areas expect the coast (GLS) where the gusty winds will prevail into Sunday morning. Fowler && .MARINE... Issued at 1156 AM CST Fri Feb 20 2026 Areas of fog will continue through tomorrow morning before a frontal boundary pushes offshore. Increasing northerly winds and building seas are expected by late Saturday afternoon into the evening hours in the front's wake. Winds are likely to gust to gale force while seas build to 6-10 feet. Therefore, a Gale Watch is currently in effect through from 00-12Z Sunday. Conditions should improve late Sunday into Monday, with onshore flow returning by Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
