986 FXUS64 KHGX 281646 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1146 AM CDT Fri Jun 28 2024 ...New AVIATION... .SHORT TERM... (Today through Saturday Night) Issued at 326 AM CDT Fri Jun 28 2024 High pressure will continue to reign over SE Texas today with onshore flow continuing to funnel in moisture. This moisture will continue to be trapped under this dome of high pressure, continuing the streak of hot and humid days. A Heat Advisory is in effect for much of SE Texas this afternoon as heat indices reach to around 105- 110F. The Heat Advisory will likely be needed again for Saturday as we remain in a persistent forecast. Diurnally-driven showers and thunderstorms will continue to be possible this afternoon and again Saturday afternoon, particularly as the sea breeze moves inland. Otherwise, expect skies to be partly cloudy with generally light SSE winds. Max highs today and Saturday will be in the mid to upper 90s inland and in the upper 80s to around 90F along the coast. Lows for tonight and Saturday night will continue to be on the warmer side as temperatures drop into the upper 70s to around 80F As the streak of heat continues, please remember to practice heat safety! Stay hydrated, avoid strenuous activity at the hottest part of the day, and LOOK BEFORE YOU LOCK! Also, for pets...if the ground is too hot for the palm of your hand, it is too hot for their paws! Adams && .LONG TERM... (Sunday through Thursday) Issued at 326 AM CDT Fri Jun 28 2024 Guidance shows the broad area of low pressure over the western Caribbean Sea being situated in the Bay of Campeche by Sunday...eventually tracking wnw into Mexico Sunday night & Monday. Doubtful it`d be much of a concern locally, though we`ll probably see a bump in seas offshore. Otherwise,continued hot through most of the week with mid and upper level ridging in control across southern parts of the country. The "good news" is we should mostly be positioned to the south of the center of the ridge and in the easterlies. So although temps will remain above normal, we can`t totally rule out some isolated diurnally driven shra/tstms most days (ie seabreeze activity). 47 && .AVIATION... (18Z TAF Issuance) Issued at 1146 AM CDT Fri Jun 28 2024 VFR conditions and southerly winds around 10 knots will prevail through the evening hours. Isolated showers have begun to develop south of I-10 this morning and will drift northward through the afternoon. The sites with the best potential of an afternoon downpour are SGR/HOU/IAH/CXO. By sunset, any convection that develops will dissipate. The attention then turns to another round of MVFR ceilings and slightly reduced visibilites due to patchy fog at the northern sites (CXO and northward). After 09Z-10Z, MVFR ceilings are expected to build back in and should prevail till 15Z when southerly winds around 10 knots pick back up. Batiste && .MARINE... Issued at 326 AM CDT Fri Jun 28 2024 Onshore winds will prevail into early next week. A broad area of low pressure over the western Caribbean Sea is forecast to move into the Bay of Campeche later this weekend. Though this system should remain well to our south, look for seas to increase as a longer period 4-6ft swell moves into the upper Texas coastal waters Saturday night and Sunday. 47 && .PRELIMINARY POINT TEMPS/POPS...
