DISCUSSION

Issued at 1229 AM CDT Wed Jul 29 2026

The center of the large upper ridge that has brought us hot and dry conditions over the past several days will remain over the state of New Mexico and adjacent Texas Panhandle today. However, the eastern periphery of the ridge will erode a tad. At the same time, a deepening trough across the CONUS east of the Mississippi River, will allow a weak cool front to back door into the region by late afternoon/early evening today. But, ahead of the front, a Heat Advisory will remain in place today, as afternoon highs will climb into the upper 90s to around 100 degrees again, resulting in heat indices ranging from 105 to 109 degrees. With the aforementioned front, a chance of showers and thunderstorms will return mostly across our Arkansas and northern Louisiana forecast zones, as the front is expected to stall across South-Central Arkansas and Northeast Louisiana this evening. Some of this convection could linger into the pre-dawn hours on Thursday.

As we move into the day on Thursday, the front will shift a little more westward across the region, eventually stalling along a line from Southeast Oklahoma to near Texarkana to around the I-20 corridor of North Louisiana. Showers and thunderstorms are expected to develop again across much of the same locations, and possibly into portions of Northeast Texas and Southeast Oklahoma. This rain and associated cloud cover should bring us some relief from the heat. Because of this, we will hold off extending the current advisory into Thursday. However, areas that aren't expected to receive precipitation could see Heat Advisory conditions, so we can't rule out an advisory for some locations during this period. By Friday, the front will retreat back to the northeast, as the ridge will try to re-establish itself over the region. This will bring a return of hot and mostly dry conditions areawide, and the possibility of another widespread heat advisory. But, this pattern will be short-lived, as the center of the ridge will shift westward. With a deep trough remaining across the eastern CONUS, the upper pattern over the region will shift to more of a northwesterly flow. Models are suggesting the flow will drive another weak cool front into the region over the upcoming weekend, with the front stalling south of the I-20 corridor on Sunday. Rain chances are expected to return with this front, mainly along and south of I-20 corridor during the weekend. As of now, long-term progs have dry weather returning to the region for the first portion next week, as the front is expected to shift south of the area. /20/

AVIATION

(12Z TAFS) Issued at 623 AM CDT Wed Jul 29 2026

For the 12z TAF period...IR imagery continues to show widespread high AC and cirrus spreading southward across SE OK and SW AR and while some of this will dissipate as it moves south, feel like this cloud cover is destined for our terminal airspace later today into tonight. What will also come south or will actually backdoor its way south and west into our airspace is a weak cold front and with that cold front will be the possibility of convection along and behind the boundary. This means VCTS for the TXK/ELD/SHV and MLU terminals as early as 18-20z at the ELD and TXK terminals and closer to 21-00z for the SHV and MLU terminals. TYR, GGG and LFK terminals should stay dry. Not seeing low ceilings moving into our Deep East Texas terminals this morning so did remove this from the 06z TAF package.
