FXUS64 KHGX 120512 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1212 AM CDT Tue May 12 2026 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Warm weather expected throughout the work week. - Increasing clouds, humidity, and isolated rain chances over the weekend. && .DISCUSSION... Issued at 1211 AM CDT Tue May 12 2026 Water vapor imagery shows the mid-upper trof axis crossing over the Sabine and into Louisiana. As it continues its eastward progress, the flow aloft will transition to a drier northwesterly direction as ridging to our west gradually moves in our direction into midweek. Dry, mostly seasonable wx can be expected the next several days, though daytime highs will probably trend about 3-5F above norms with the lower PW air (<1") filtering in. Heading into the late work week, surface high pressure will be moving off to the east and we'll see a return to a more dominate SSE llvl wind coming in off the Gulf. This will bring along some higher dewpoints/RH's, cloud cover, and warmer overnight low temps. Mid-upper ridging weakens and tracks to our east over the weekend. A strengthening southerly low level flow will drive PW's back up into the 1.5-1.8" territory, but with the lack of significant forcing or weather systems in the vicinity this weekend, rain chances will probably be limited to some isolated diurnally driven showers or streamer showers. Possibly some better chances arriving late Monday or Tuesday in association with some weak troffiness moving across the Southern Plains. 47 && .AVIATION... (00Z TAF Issuance) Issued at 620 PM CDT Mon May 11 2026 VFR conditions will prevail throughout the TAF period with one potential exception. Some model guidance is hinting at a brief window for reduced visibilities at the northern three terminals between 11Z-14Z. Drier air will be moving in, but model soundings and low dewpoint depressions are supportive of a brief patchy fog window early Tuesday morning. Confidence is leaning more towards the low to moderate side, so covered this with a short TEMPO for CLL/UTS/CXO. Outside of that, mainly a wind forecast. Breezy northerly to northeasterly winds late this afternoon will become light and variable overnight, then pick up again out of the northeast again on Tuesday generally in the 5-8 kt range. Batiste && .MARINE... Issued at 1211 AM CDT Tue May 12 2026 Moderate northeast winds will diminish as the day progresses Tuesday as high pressure settles in across the area. We will probably see a late afternoon and evening seabreeze (SE winds). Wind regime into Thursday will be dominated by the landbreeze (light offshore winds late at night and in the mornings) and seabreeze (onshore winds in the afternoon and evening). A tightening pressure gradient will lead to increasing southerly winds and building seas heading into the weekend. 47 && .PRELIMINARY POINT TEMPS/POPS...
