- Oppressive heat looks to return as clouds and precipitation gradually push out of the area into the weekend.

- Afternoon showers and thunderstorm chances will remain for at least portions of the area through through next week.

DISCUSSION

Issued at 1235 AM CDT Thu Sep 3 2026

We are continuing to see the impacts from the remnants of Edouard, which remains centered near Henderson County in east Texas early this morning. Rain has been ongoing for much of deep east Texas from Angelina, San Augustine, Nacogdoches, and Cherokee counties through the day today, and now this activity is spreading northward into Smith County. Expecting this trend to continue in these areas through the remainder of the overnight hours. One thing of concern, a handful of 00z model guidance this morning came in showing some bullseyes of around 4-6 inches and isolated pockets higher across Cherokee, Angelina and adjacent counties into FWD and HGXs forecast areas. As a result, I have maintained the Flood Watch for these areas through early Thursday morning. So far the ground has been able to soak up the majority of the rainfall today, with minimal flooding impacts actually observed. We could even see some lingering showers across these areas through the day Thursday, although the impacts should be less. Hopefully models are onto something by kicking this system out of the area by Thursday night into Friday.

Once the rainfall from Edouard end, we will move back into a more regional pattern where we will see more summertime heat and daily diurnal thunderstorm chances. The upper-level ridge currently anchored over the Mid-South will gradually weaken, with ridging redeveloping farther west across the southern Plains. This will help our area reach back above climatological normals, with afternoon highs increasing ever so slightly each day through the weekend and remaining warm well into next week. I don't think we will quite make it to Heat Advisory criteria, although we will be close across our eastern zones of north central Louisiana. Being that it remains borderline for today, I have elected not to issue any heat headlines at this time, although it is looking good that we will need one later this weekend or into next week.

Looking farther out, guidance continues to advertise a fairly low-amplitude pattern, with generally westerly/zonal flow aloft along the southern periphery of the developing ridge. In other words, there is not a particularly exciting synoptic-scale feature waiting in the wings. Instead, precipitation chances should become increasingly governed by the daily heating cycle, with afternoon and evening convection favored primarily across areas south of I-20. Outside of any lingering rainfall directly associated with Edouard, WPC continues to only suggest another tenth to a quarter of an inch of rainfall across any portions of the area. The overall takeaway...Edouard exits the stage to the left, the ridge rebuilds, the thermometer remembers what summer is supposed to feel like, and the diurnal thunderstorm machine gradually cranks back up. /33/

AVIATION

(06Z TAFS) Issued at 1235 AM CDT Thu Sep 3 2026

VFR conditions will continue overnight across much of N LA and Srn AR, as SKC with some thin cirrus development is expected, but cigs will continue to deteriorate across E TX as convection redevelops near and E of the remnant low center from what was Edouard which has drifted W of TYR to just S of TRL. A mix of IFR/low MVFR cigs will develop across the WSW sections of E TX overnight, primarily affecting the TYR/LFK and possibly GGG terminals, and have tempoed in vsby reductions for these areas and wind gusts to 25-30kts as well at TYR before the convection gradually diminishes from E to W across E TX through daybreak. Should also see some scattered MVFR cigs develop after 12Z across more of NE TX as well as portions of Wrn LA/SW AR, before lifting by mid and late morning while eventually scattering out by early afternoon. Have maintained VCSH mention at TYR/LFK through at least mid-afternoon, although convection coverage should gradually diminish through the afternoon as the remnant low center continues to drift WSW away from the region. Isolated convection may develop elsewhere across the region over portions of N LA/SW AR, but low confidence precludes VCSH/VCTS mention for the remaining terminals attm. While much of the cu field should diminish after 00Z Friday, some residual AC/cirrus may linger through the end of the TAF period over the Wrn sections of E TX, as well as with a weak Erly wave and attendant isolated to scattered convection over Ern LA/SE AR that will diminish this evening as it approaches MLU/ELD. Light SE winds overnight, except 10-15kts with gusts to 25kts over the Wrn sections of E TX, will become S 5-10kts after 15Z, with occasional higher gusts to 20kts possible at TYR. /15/

SPOTTER INFORMATION STATEMENT

Issued at 1235 AM CDT Thu Sep 3 2026

While widespread spotter activation is not needed, some assistance might be needed for today across portions of Deep East Texas as the remnants of Edouard continue to move through this area.
