DISCUSSION

Issued at 1234 PM CDT Tue Aug 11 2026

I was on the fence about putting out a Heat Advisory for today as we will remain borderline at best. After much consideration and deliberation with neighbors, I elected to go ahead and issue one for today and continue it through Friday evening. The main reason for issuing today was because of our heat index values reached yesterday, we had a handful of locations that were able to get above the 105 degree threshold, and I think we will be able to reach this in a few locations as well today. I don't think we will have much of a problem reaching our threshold for Heat Advisory for the rest of the week, which is why I decided to take it out through Friday. The big question will be if there are any areas towards the end of the week that need to be upgraded to Excessive Heat Warning.

We are seeing a few very isolated showers starting to pop up on radar this afternoon, and satellite imagery is showing a few areas in Louisiana with some growing cu. As a result, I went ahead and added some 20 percent PoPs for most areas along and south of I-20 in Texas and then the majority of our Louisiana parishes through the afternoon hours. The rest of the week and into the weekend is expected to remain dry, although I could see some potential that we could see a few isolated convection across portions of our southern zones at times, but I am not expecting anything widespread or significant through the rest of the week. With the extended period trending warmer and drier, this will bring a chance for drought conditions to worsen and fire weather concerns to increase. Something that we will need to keep a close eye on. /33/

AVIATION

(18Z TAFS) Issued at 1224 PM CDT Tue Aug 11 2026

As expected, diurnally induced cu field has developed across NE TX, SW AR and all of N LA early this afternoon. Even beginning to see some isolated showers developing across portions of Deep East Texas. For the 18z TAF package, chose not to mention any Wx with these TAFs as storm coverage is best handled with an AMD if necessary. Otherwise, scattered cu field should fair off near or after sunset this evening with VFR conditions prevailing through much of the night. The one exception to this could be the development of IFR/MVFR ceilings near or just before sunrise across Deep East Texas, possibly impacting the LFK/TYR/GGG terminals. Cannot rule out these same conditions just after sunrise at the SHV/TXK terminals as well. Eventually, any morning ceiling restrictions will return to VFR conditions by late morning on Wednesday or towards the end of this 24hr TAF package.
