FXUS64 KHGX 180454 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1154 PM CDT Thu Sep 17 2026 ...New DISCUSSION, AVIATION, MARINE... .KEY MESSAGES... - Hot and dry, with lower humidity through Saturday. - Humidity returns Sunday along with daily diurnal storm chances into next week. && .DISCUSSION... Issued at 1128 PM CDT Thu Sep 17 2026 The tropical PWAT plume and subtle sfc boundary that enhanced scattered showers and thunderstorms in our southern and coastal counties on Thursday will push well to our west on Friday. Meanwhile, much drier conditions are approaching our region from the east. Unfortunately, this 'new' air mass will not bring much cooler temperatures. But humidity on Friday and Saturday should be lower, with afternoon dew points falling into the 60s for many inland locations. Inland afternoon highs should remain well into the 90s. But the drier air is likely to allow for somewhat cooler overnight temperatures, especially away from the coast and outside the urban heat island. A few locally cool spots could even drop into the upper 60s Friday night and again Saturday night. I guess we'll take what we can get. Despite the dry air, there may be a few stray showers over the Gulf and near the coast through Friday morning. By Sunday and beyond, we find ourselves back in a humid and very hot pattern. We think there will be a daily risk of isolated to scattered showers and thunderstorms, especially in our southern and coastal zones. Other than persistent mid/upper ridging, there are no other significant synoptic forcings that are expected to influence the pattern. No fall weather anytime soon. Sorry y'all. Self && .AVIATION... (06Z TAF Issuance) Issued at 1128 PM CDT Thu Sep 17 2026 VFR conditions prevail at all sites with light and VRB winds for inland sites and ESE winds at 5-10 kts along the coast. Winds increase and turn ~E at 6-10 kts by late tomorrow morning at all sites. A dry air mass will push westward into our region throughout the night and tomorrow, limiting potential for convection. Any showers/storms that do develop will likely be diurnally driven and isolated in nature. Otherwise, a dry and VFR day is in store for tomorrow. MLG && .MARINE... Issued at 1128 PM CDT Thu Sep 17 2026 Residual gusty winds and enhanced seas are expected to linger into Friday morning, especially offshore. Otherwise, we expected light to moderate onshore flow over the next several days. Friday and Saturday should be much drier, though we can't rule out a stray shower over the Gulf. Daily risk of isolated to scattered showers and thunderstorms returns Sunday or Monday. && .PRELIMINARY POINT TEMPS/POPS...
