KEY MESSAGES

Issued at 252 PM CDT Tue Aug 4 2026

- The next 48 hours will be the hottest days of the workweek before a gradual cooldown to near-normal summertime heat (mid-90s).

- Chances of rain gradually return through the rest of the week into the weekend, mainly in the form of typical summer afternoon thunderstorms.

DISCUSSION

Issued at 252 PM CDT Tue Aug 4 2026

Yet another day ensues under the ridge with some deviations in its strength yielding just enough room for convection to start percolating across central Louisiana (and along I-49) this afternoon. This ridge, centered across the Desert Southwest with an axis of subsident air extending eastward across the southern Great Plains. As it does so, the fading strength of this axis will open certain spatiotemporal windows of opportunity for convection to blossom each afternoon for the rest of the week. Current persistence trends and high-resolution guidance also continue to suggest more efficient mixing and dewpoints in the mid-to-upper 60s that might preclude the area from heat advisory thresholds through the rest of the workweek. These drier conditions have also enhanced surface fuels for wildfire development, especially across East Texas. Travelers should remain cognizant of anything that could spark a fire, such as a dragging tow chain or a discarded cigarette.

Long-range guidance suggests the next synoptic pattern change taking shape in the form of broad troughing as the Four State Region sits between ridging centered across the Desert Southwest and the Atlantic Ocean into the Southeast U.S. coastlines. This will enhance the diurnally-driven convective pattern across the area to yield WPC QPF values of 0.1 to 0.5 inch, mainly distributed along and east of I-49. A relatively dry pattern is expected as a result. /16/

AVIATION

(00Z TAFS) Issued at 644 PM CDT Tue Aug 4 2026

VFR conditions will continue through much if not all of the 05/00Z TAF period. While much of the elevated cu cigs will diminish across the area early this evening, a cu field should again linger this evening/overnight across portions of extreme Ern TX/Wrn LA/extreme Srn AR, with additional cu developing by late morning Wednesday elsewhere across the region. Brief MVFR cigs may again develop by/shortly after 12Z across portions of Deep E TX (primarily affecting LFK), but will quickly lift/scatter out by mid-morning. Isolated to widely scattered convection will again develop by mid to late afternoon Wednesday from portions of SE OK/extreme Ern TX into SW AR and much of N LA, but low confidence and brevity precludes mention in the TAFs attm. Any convection that develops will dissipate by/shortly after 00Z Thursday, with the attendant cu field diminishing by the end of the TAF period as well. Light SSE or Lt/Vrb winds tonight will become SSW 5-7kts after 15Z. /15/
