145 FXUS64 KHGX 102311 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 511 PM CST Wed Dec 10 2025 ...New AVIATION... .KEY MESSAGES... - Nice, seasonable weather anticipated through Thursday, followed by warmer conditions Friday & Saturday. - We`ll be on the lookout for some sea fog beginning Friday night and into Saturday night (if water temperatures don`t climb another few degrees between now and then). - A stronger front passes through late Saturday night and Sunday morning with some scattered showers in advance. && .DISCUSSION... Issued at 128 PM CST Wed Dec 10 2025 Weak front is in the process of moving through the area, which should keep readings near seasonable norms through Thursday. As high pressure moves to the east and southeast winds resume late in the day tomorrow, we`ll see a gradual return of Gulf moisture and associated higher humidities, temps, and RH`s Friday and Saturday. The next front will be entering north Tx on Friday, but will likely stall for a while just north of our CWA. Moisture will pool ahead of this feature and we should eventually see some scattered shower activity develop Saturday. Cold high pressure tracking SSEwd through the northern CONUS, Midwest and Mississippi Valley will give the stalled front its needed southward push through our region Saturday night and off the coast Sunday morning. The more significant cold air will be off to our northeast, though we will see another chill in the air with temps back into the 30s/40s at night and 50s/60s during the day through Monday. High pressure moves off to the east and returning southerly flow will quickly drive moisture levels back up heading into Tues. This along with some Pacific moisture streaming below a mid-upper trof moving toward the area should provide for a decent shot of rainfall Tuesday into Wednesday. 47 && .AVIATION... (00Z TAF Issuance) Issued at 508 PM CST Wed Dec 10 2025 Not much change from last cycle - main feature is to complete the trend of veering winds from northerly this evening to southeasterly by tomorrow afternoon. At most sites this is represented by a VRB line, as change in winds is likely to happen at low speeds and be somewhat herky-jerky. It is more explicit at GLS where wind speeds stay up to make the change in winds more obvious. && .MARINE... Issued at 128 PM CST Wed Dec 10 2025 A weak, dry, front will be pushing off the coast early this evening. We may need some caution flags in the Gulf waters for a short time period overnight with some 15-20kt NE winds. A southeast flow will resume Thursday afternoon and continue into Saturday night. We will need to be on the lookout for some sea fog development beginning Friday night as warm, moist air moves over the cooler shelf waters. One limitation, however, would be if water temperatures climb 2-3 degrees before then. The fog threat will cease once we see out next cold front pass off the coast Sunday morning followed by moderate to strong northeast winds and building seas. Small Craft Advisories should be anticipated behind this front. 47 && .PRELIMINARY POINT TEMPS/POPS...
