DISCUSSION

Issued at 1240 AM CDT Thu Jul 30 2026

The weakening of the eastern periphery of a large upper ridge, that brought us hot and dry weather over the past several days, allowed a weak cool front to backdoor into the Lower Mississippi Valley, as a deep trough has settled across the eastern CONUS. Although the front didn't quite get into our forecast area, showers and thunderstorms that developed along the front were able to move into portions of our SW Arkansas zones and the northern half of McCurtain County, OK. This convection has finally diminished and conditions should remain quiet over the next several hours. However, as we move through the overnight period, the front will continue backdoor into our forecast zones. Progs suggest the southwestward movement of the front will come to a halt somewhere near a line from Southeast Oklahoma to near Texarkana to around the I-20 corridor of North Louisiana Thursday afternoon. Showers and thunderstorms are expected to develop again over the area, with the best chances during the afternoon across McCurtain County Oklahoma, all of SW Arkansas, and along and east of the Interstate 49 corridor of our Louisiana parishes. Although the synoptic set-up isn't great for severe weather, an isolated strong to severe thunderstorm with damaging wind gusts can't be ruled out, along with some locally heavy rain. Hot and humid conditions will remain in place ahead of the expected rainfall, so the current Heat Advisory has been extended until 8 PM Thursday evening.

By Friday, the front will retreat back to the northeast, as the aforementioned 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 areawide heat advisory. But, this pattern will be short-lived, as the center of the ridge will shift westward. With the deep trough remaining across the eastern CONUS, the upper pattern over the region will become more northwesterly. Models continue to suggest the northwesterly flow will drive another weak cool front into the region over the upcoming weekend, with the front eventually stalling south of the I-20 corridor on Sunday. Rain chances are expected to return with this front, with the best chances each day along and south of the Interstate 20 corridor. The front is expected to wash out by early next week, with upper ridging returning across the region. This would bring a return in hot and dry conditions for the first half of next week. However, long-term progs are trying to hint at some afternoon rain chances in our Eastern Louisiana zones next Tuesday and Wednesday. /20/

AVIATION

(12Z TAFS) Issued at 624 AM CDT Thu Jul 30 2026

Cannot rule out some MVFR ceilings this morning at the TYR/GGG and LFK terminals this morning as we are seeing some of this blossom out of Deep East Texas. Otherwise watching some convection north of the ELD terminal trying to spill southward. This is oriented near the stalled frontal boundary so have begun the ELD terminal with VCSH. Think it will be later this afternoon before we see more scattered convection, possibly impacting our SW AR and N LA terminals. Most, if not all convection should dissipate in coverage after 03z this evening.
