KEY MESSAGES

Issued at 349 PM CDT Wed Sep 9 2026

- A gradual weakening of the upper ridge is expected by the end of this week, making way for a trough to drop south with rain chances increasing areawide on Friday.

- Upper ridging will eventually return across the region, limiting daily convection to diurnally driven activity mainly during peak heating hours by next week. This could bring the return of Heat headlines.

DISCUSSION

Issued at 349 PM CDT Wed Sep 9 2026

A few isolated showers are starting to developing across portions of East Texas and SW Arkansas this afternoon with peak heating. But overall, upper-level ridging has kept things much quieter than the previous days. Temperatures have return back into the mid to upper 90s, with a few triple digit readings likely before sunset today. Can't rule out some additional development of showers and thunderstorms across the remainder of the region this afternoon into the early evening hours. However, this convection should stay very isolated in coverage and will diminish with the loss of daytime heating. On tomorrow, the ridge will start to break down across the region. This will allow an upper-level trough push southward into the area, bringing us some rain chances. The precipitation associated with the trough will likely remain along and north of I-30 corridor during the day. There will also be some additional rain chances across our Deep East Texas and adjacent Central Louisiana zones, mainly along and south of US Highway 84 corridor, as weak disturbances in the Gulf push some convection northward into those zones. We will likely still see highs in the mid to upper 90s in many locations, but rain and cloud cover will yield slightly slightly cooler temperatures in some of the aforementioned locations. At this time, will hold off on heat headlines, as models suggest we will be borderline on the advisory criteria.

As we move into Friday, the combination of the upper trough and disturbances across the northern Gulf will yield widespread rain chances across the region. Some of this convection could start during the pre-dawn hours, especially for locations along and north of I-30. We should see cooler temperatures with the rainfall, but many locations could still reach the low to mid 90s. Rain chances will remain in the forecast over the upcoming weekend, but progs suggest the best chances will be along and east of a line from Lufkin Texas to Shreveport to El Dorado Arkansas. Upper ridging returns across the region for the first half of next week. Can't rule out some additional showers and thunderstorm during peak heating, but coverage will become more isolated and confined to our Deep East Texas and adjacent Central Louisiana zones. With drier conditions expected, heat headlines could return across the region. /20/

AVIATION

(00Z TAFS) Issued at 545 PM CDT Wed Sep 9 2026

Much less convection today to deal with compared to the last several days so feel like for this package, we can let the late addition of any prevailing VCTS to start. Otherwise what's left on radar should quickly dissipate over the next couple hours with only cirrus blowoff remaining. Did TEMPO some MVFR ceilings near and especially just after sunrise at the LFK terminal but otherwise, we should see a growing cu field throughout the day. Much like today, isolated storm coverage will not warrant a mention in this TAF package at any one location for Thursday but can't rule it out of course.
