241 FXUS64 KHGX 091745 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1245 PM CDT Tue Jul 9 2024 ...New AVIATION... .SHORT TERM... (Today through Wednesday Night) Issued at 235 AM CDT Tue Jul 9 2024 As Beryl continues heading toward the Illinois-Indiana areas today (last advisory from the National Hurricane center was issued yesterday evening), slightly drier air will be working into the area generally from the north today, and these lower moisture levels in combination with north surface winds will help to suppress most convective development inland. Closer to the coast and offshore, moisture levels might remain deep enough for possible shower/ thunderstorm development, especially if surface winds can come back around to the southeast and south as the day progresses. Lingering moisture in this same area could allow for more development, late tonight off the coast and during the daytime/afternoon hours in and around the coastal counties. Of more interest and concern will be today`s high temperatures and heat index values. Despite having highs mainly in the lower 90s and heat indexes peaking in a 97-106ish range (all under Heat Advisory criteria), extensive power outages caused by Hurricane Beryl have left millions without proper cooling. In the days after the Houston Derecho, we saw a spike in heat-related illnesses following the extensive power outages across the metro area. Given these extenuating circumstances, all of Southeast Texas will be under a Heat Advisory today/tonight. If you do not have access to AC/cooling due to power outages, please take all precautions. Here are some tips to stay cool without power: wear loose/ lightweight clothing, try to stay on the lowest level of your home, keep your curtains and blinds closed during the daytime to limit solar radiation entering your home, drink plenty of water/avoid alcohol and heavy meals, and take a cool shower/bath to lower skin temperature. For those with generators, please be sure that they are properly ventilated...NEVER use generators indoors. In that same vein, NEVER use barbecue grills indoors either. Be sure to check in on your family, friends, and pets as well. Stay safe and stay as cool as you can. 42/Batiste && .LONG TERM... (Thursday through Monday) Issued at 235 AM CDT Tue Jul 9 2024 It`s July and the hot and humid conditions will persist through the next several days. The low temperatures will be in the low to mid 70s through the end of the work week, increasing to the mid to upper 70s during the weekend. The high temperatures during the long term period will be generally in the the low 90s over areas north of I-10 and in the upper 80s to low 90s over areas south of I-10 through the upcoming weekend. The highs will increase into the mid 90s early next week. With that being said, dewpoints will likely remain elevated and in the mid to upper 70s. As a result conditions will continue to feel pretty humid. Heat indices will likely be between 103-108 deg F and with many without power, heat impacts could be a concern for many folks out there. Please continue to heed the advise detailed in the short term discussion to better protect yourself and your family from the heat impacts. With respect to rain chances, we may see some isolated to possibly scattered showers and storms each day, in particular during the afternoon to early evening hours. So far, Friday and Saturday seem to be the days of higher rain chances as pulses of moisture from the Gulf and a weak upper level trough slowly moves across the Southern Plains. 24 && .AVIATION... (18Z TAF Issuance) Issued at 1237 PM CDT Tue Jul 9 2024 A few SCT to BKN MVFR ceilings will continue this afternoon before becoming VFR/clear skies this evening. A few showers with isolated storms will still be possible along the coastal terminals this afternoon. Winds will generally remain from the NNW at around 10 knots or less, becoming more northerly on Wednesday. Overall, VFR conditions are expected through the period. JM && .MARINE... Issued at 235 AM CDT Tue Jul 9 2024 Seas will continue to subside today. Caution flags will remain across the bays and Gulf waters through mid morning, mainly for seas and to give extra precaution for those surveying the waters and or helping in the restoration process post Hurricane Beryl. Light onshore winds and seas at 3 feet or less are expected throughout the next several days. There is a chance for isolated to scattered showers and storms each day, highest from Thursday to Saturday, and could result in higher winds and seas in and around storms. 24 && .PRELIMINARY POINT TEMPS/POPS...
