Issued at 1124 AM CDT Mon Aug 31 2026

- Dry conditions to continue through today as an upper-ridge migrates east across the Mid-Mississippi Valley. - Rain chances to increase south of I-20 and across portions of Deep East Texas through midweek with Potential Tropical Cyclone 5.

- Afternoon and evening showers and thunderstorms possible through the weekend with a weak disturbance to the south.

DISCUSSION

Issued at 1148 AM CDT Mon Aug 31 2026

For the final day in August, hot and dry conditions to prevail across the region with temperatures to approach triple digits across portions of east and northeast Texas. Heat index values this afternoon will climb to near 105 degrees across much of the region.

Moving into September, the pattern begins to shift, allowing for temperatures to slip a little further from the triple digit mark as the upper-level heat ridge over the central CONUS moves east into the Appalachians. The departing ridge will allow for a weak tropical disturbance in the north central Gulf of America to swing northwest into southeast Texas bringing increased rain chances to to the lakes region of Deep East Texas and portions of west- central Louisiana from Tuesday into Wednesday. The track forecast for this disturbance places the disturbance across east-central Texas by midweek which could be ideal for producing much needed rainfall to the already drought stricken ArkLaTex, but could be problematic if a heavy rain threat materializes. At this time no such widespread heavy rainfall signal exists but will continue to prudently monitor trends for any signs of this type of threat manifesting in later model cycles.

A broad inverted trough to retrograde west across the Gulf of America late in the workweek, undercutting the upper-ridge across the east coast. This trough will provide enough instability and mixing to limit afternoon highs to the mid to upper 90s through the weekend. Additionally, scattered showers and thunderstorms could be possible each afternoon. /05/

AVIATION

(18Z TAFS) Issued at 1232 PM CDT Mon Aug 31 2026

Conditions are expected to remain VFR through the period. Winds should remain light and variable, becoming calm for some sites overnight. There is some uncertainty late in the period due to Potential Tropical Cyclone Five. The current track takes the center into East Central TX but outer rainfall bands could reach as far as KLFK or KTYR. VCTS has been included at KLFK in this package due to relatively higher confidence, but other sites could see vicinity impacts if the system takes a more easterly track. /57/
