FXUS64 KHGX 082319 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 619 PM CDT Mon Jun 8 2026 ...New AVIATION... .KEY MESSAGES... - Increasing heat risk is forecast as the week progresses. - High risk of rip currents will persist through tonight, with risk levels fluctuating between moderate and high through the week. - Isolated to scattered showers and storm chances, mostly during the afternoon hours, will continue this week. && .DISCUSSION... Issued at 1219 PM CDT Mon Jun 8 2026 A subtropical jet streak and associated enhanced mid/upper-level moisture remains over the area but will continue to weaken/push eastward as subtropical ridging builds westward from the Gulf. Earlier light rain with this feature has dissipated, though some patches of light rain/sprinkles may still occur along the coast this afternoon and evening. Otherwise, isolated to widely scattered showers and storms will continue to develop over inland areas, with the relatively highest chances in the Brazos Valley. Activity will diminish this evening. Subtropical ridging will be centered over Southeast Texas through the week. This will prevent widespread convection, but still expect isolated to scattered showers and storms to develop each afternoon with daytime heating, onshore flow, and the sea breeze. Highs will mainly be in the lower 90s. Taking into account the typical high bias of NBM dew points, there will only be a low chance of heat indices reaching heat advisory criteria. But heat will certainly still be a concern for those not acclimated to it. Towards the end of the period, the ridge may start to weaken as troughing amplifies over portions of the central and eastern CONUS. This may result in an increase in convective coverage starting around Sunday with some frontal boundaries stalling north of our area, but details remain uncertain at this time. JDavis && .AVIATION... (00Z TAF Issuance) Issued at 532 PM CDT Mon Jun 8 2026 Sparse showers will taper off this evening with winds becoming light and variable overnight. MVFR CIGS/Decks fill in again overnight into the early morning hours of Tuesday. Could see some isolated, brief instances of IFR CIGs during this early morning period as well. Otherwise FLs will return to VFR levels by Tuesday afternoon as south/southeast winds strengthen. Some sparse, light showers could develop along the sea breeze during the late afternoon. Included mentions of showers for areas south of I-10 where confidence is greater, though coverage will likely be sparse, much like today. Showers taper off in the evening with winds becoming light/variable again Tuesday night. 03 && .MARINE... Issued at 1219 PM CDT Mon Jun 8 2026 Southerly to southeasterly winds will persist for the week, with winds dipping in and out of small craft exercise caution criteria. Winds this afternoon and tonight will be right around 14-15 kts, but will not include caution flags at this time. Caution flags may be needed towards the middle of the week. Isolated showers and storms are still possible but chances will decrease slightly as the week goes on. && .PRELIMINARY POINT TEMPS/POPS...
