143 FXUS64 KHGX 100449 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1149 PM CDT Fri Aug 9 2024 ...New AVIATION... .SHORT TERM... (This evening through Saturday Night) Issued at 358 PM CDT Fri Aug 9 2024 Will be issuing a brief Excessive Heat Warning for the rest of this afternoon as portions of the CWA have reached criteria (HI >=113F). Will also be extending the Heat Advisory for all of the CWA through tomorrow evening. So, with this pattern remaining in place, above normal temperatures are going to persist through the weekend. Deep ridging from the mid to upper levels along with the weak stationary front in the general vicinity of SE TX will help to keep hot and humid conditions in the forecast for tomorrow. Highs on Sat could be a bit "cooler"... only ranging in the mid to upper 90s, but heat index values are going to stay elevated (102-108F). Overnight lows (for both tonight and tom- orrow night) will be in the upper 70s to lower 80s. Please continue to be mindful of heat safety. Drink plenty of water; LOOK before you LOCK and try to avoid overexertion outdoors, especi- ally during the hottest parts of the day (1-5PM). 41 && .LONG TERM... (Sunday through next Thursday) Issued at 358 PM CDT Fri Aug 9 2024 You know the level in Mario Bros. where the Sun is chasing you while you are just trying survive and make it to the next level? ...Yeah...so about this week... The mid-level ridge is going to remain parked overhead through the duration of the long-term period. This will continue to result in above normal temperatures for the majority of Southeast Texas. Light onshore flow will persist at the surface as we remain on the western periphery of a surface high pressure centered over the Gulf of Mexico. Daytime highs will reach into the upper 90s with a few locations reaching 100F. The combination of increasing temperatures and humidity will result in high heat index values of 108-112F, with the peak of heating expected Tuesday through the weekend. A Heat Advisory will likely be needed through the week next week. We will continue to monitor for the potential for heat indices to reach the Excessive Heat Warning criteria. In any case, it will be hot this week with only slight chance of rain in the forecast for Monday and Tuesday. This is a less than 30% chance and it is focused more along the Coastal Plains and Barrier Islands. Continue to practice heat safety by staying hydrated, avoiding strenuous activity during the hottest part of the day, and LOOK BEFORE YOU LOCK! Pet owners, if the ground is too hot for the palm of your hand, then it is too hot for your pets` paws. && .AVIATION...
