FXUS64 KHGX 241812 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX Issued by National Weather Service Tallahassee FL 112 PM CDT Tue Mar 24 2026 ...New AVIATION... .KEY MESSAGES... - Mid-level high pressure will keep conditions dry and temperatures well-above normal over the next several days. - Persistent southerly flow will lead to the development of patchy to areas of fog (some locally dense) and low clouds over the next several nights. - Cooler temperatures are possible over the weekend with the passage of a dry cold front. && .DISCUSSION... Issued at 1203 AM CDT Tue Mar 24 2026 The cold front that stalled just north of the Brazos Valley and Piney Woods region will gradually lift northward tonight into early Tuesday. Light variable winds are expected tonight along with low temperatures mainly in the lower 60s inland and the mid 60s over the Houston metro area and the coasts. Low temperature and dewpoint spreads are expected overnight and with light winds in place, areas of patchy to dense fog will likely over portions of Southeast TX once again. It is recommended to check the traffic conditions before starting your morning commute. The day will start off cloudy but skies are expected to become partly cloudy to sunny in the afternoon. The high temperatures will warm up a few degrees, ranging in the lower 80s over the Piney Woods region, the mid to upper 80s over the rest of the inland portions, and the mid to upper 70s along the coast. South-southeast winds will be light in the morning, then strengthen to 06-12 mph in the afternoon. Winds will relax to around 5 mph near midnight. On Wednesday, a mid-level high over northwestern Mexico will strengthen and progress east into northern Mexico and western TX. This will continue to result in a warm and dry weather pattern over Southeast TX. The high temperatures are expected to range in the upper 80s to lower 90s through the end of the work week. Under the influence of southerly winds, moisture from the Gulf will continue to filter into the region. This will help keep dewpoints similar to the low temperatures (lower to mid 60s), leading to periods of patchy to locally dense fog during the overnight and early morning period for the rest of the week. The weather for the upcoming weekend still looks to be a bit cooler once a dry cold front pushes through Southeast TX sometime late Friday or early Saturday. Although there are still some model discrepancies with the timing of the front, they have been consistent on indicating cooler temperatures during the weekend. We might be lucky enough to have highs range in the mid 70s to lower 80s range on Saturday. Unfortunately, southerly flow returns quickly by early next week, leading to a warming trend once again. Cotto && .AVIATION... (18Z TAF Issuance) Issued at 1251 PM CDT Tue Mar 24 2026 Conditions across the region have returned to VFR as SCT clouds prevail. These conditions are expected to continue until late this evening when winds begin to gradually decrease into the overnight period. Model guidance isn't incredibly confident in widespread fog tanking vsbys, but with onshore flow being stronger later this afternoon when compared to yesterday, there may be enough moisture in the region to drop vsbys to IFR and/or LIFR at terminals closer to the coast. Otherwise, cigs are expected to drop to IFR across the region overnight. After sunrise, conditions gradually improve with MVFR to VFR expected again by the late morning into the afternoon. && .MARINE... Issued at 1203 AM CDT Tue Mar 24 2026 Light southeasterly winds and seas of 1-3 feet are expected for the rest of the work week. Areas of patchy sea fog is possible over the bays and adjacent nearshore waters during the next few days generally between the evening to mid-morning hours. A dry cold front could push through Southeast TX sometime late Friday or early Saturday, resulting in moderate to strong east northeast winds and elevated seas in the wake of the front. Caution Flags and Small Craft Advisories may be needed Friday night into Saturday. Conditions should improve on Sunday. Cotto && .PRELIMINARY POINT TEMPS/POPS...
