FXUS64 KHGX 232327 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 527 PM CST Mon Feb 23 2026 ...New AVIATION... .KEY MESSAGES... - Dry conditions will persist alongside a gradual warming trend through the end of the work-week. Highs reaching the mid 80s by Thursday. && .DISCUSSION... Issued at 231 PM CST Mon Feb 23 2026 A pleasant day out there with sunny skies, light winds, low humidity and afternoon temperatures in the upper 50s to low 60s. A very dry airmass remains over southeast Texas. Surface obs show dewpoints ranging from the mid-teens to low 20s, bringing relative humidity down into the teens to 20 percent range. While winds are lighter this afternoon, the dry conditions warrant caution with any fire activity. The upper level ridge will begin to break down tonight and into Tuesday, causing surface winds to transition to the southeast and south. A tight pressure gradient resulting from lee cyclogenesis over West Texas will lead to another breezy day across the region on Tuesday. This southerly flow will result in a warmer day with highs mainly in the 70s. The gradual warming trend continues throughout the week. By mid- week, 850 mb temperatures are expected to increase into the upper teens to low 20 degC by mid-week, suggesting surface highs mainly in the 80s. Even warmer conditions are expected on Thursday due to compressional heating ahead of a passing cold front, with highs reaching the mid to upper 80s. Most of the forcing and dynamics associated with this FROPA will remain to our north; therefore little to no precipitation is anticipated inland, with only slight chances for the Upper TX coast. Unfortunately, this front will not bring significant temperature impacts. In fact, a warming trend will continue into the weekend with highs mainly in the 80s. && .AVIATION... (00Z TAF Issuance) Issued at 512 PM CST Mon Feb 23 2026 VFR. Winds will continue to relax this evening and become VRB at 5 knots or less tonight. During the day Tue, expect S winds at around 10 knots in the morning, strengthening to 12-17 knots with gusts up to 25 knots in the afternoon. Winds will remain elevated, around 08-12 knots, Tue night. Llvl wind shear may be a concern for Tue night as a 30-40 knot llvl jet develops overhead. Cotto && .MARINE... Issued at 231 PM CST Mon Feb 23 2026 Winds and seas will continue to weaken and subside this afternoon to around 15 to 20 knots and below 5 ft. As surface high pressure shifts to our east, onshore flow will return across the Upper TX coast. The main marine concerns involve breezy conditions Tuesday into Wednesday ahead of an approaching cold front. Moderate to strong onshore winds and building seas can be expected after mid- day Tuesday and Small Craft Advisories will likely be issued in future updates. A cold front will move over the waters by Thursday, bringing a brief window of light to occasionally moderate offshore winds. Onshore flow resumes by Friday. && .PRELIMINARY POINT TEMPS/POPS...
