- Seasonably hot with highs in the 90s and heat index values 101-108F each day.

DISCUSSION

Issued at 1133 PM CDT Thu Aug 6 2026

Hot weather with daily rain chances should continue through early next week. Ridging reminds situated over the Four corners region, though heights and 850mb temperatures have decreased. Daytime highs should be a tad lower compared to past days, though heat indicies will still reach triple digits, thus it would be worth practicing heat safety. Shower/storm coverage yesterday outperformed the NBM slightly, and thus scattered showers/storms are likely to continue daily through the weekend into early next week as PW values continue to rise. Much of this activity will occur during the afternoon along the sea/bay breeze, generally covering the southern 2/3rds of our CWA. With deeper moisture, we'll also need to keep an eye out for patchy fog during the early morning hours.

Around Tuesday, 850mb temperatures begin to rise again as ridging builds across the northwestern Gulf. Temperatures slowly nudge upwards by a few degrees, along with heat indicies through the end of the work week as rain chances decrease.

AVIATION

(12Z TAF Issuance) Issued at 639 AM CDT Fri Aug 7 2026

MVFR to isolated IFR conditions due to low cigs are expected in/around KCLL over the next few hours. Elsewhere, VFR conditions will prevail; however, brief periods of MVFR cannot be ruled out through 14-15Z. After mid-morning, conditions will improve to VFR across all terminals under light SSE winds. Winds will strengthen in the afternoon with the seabreeze, particularly for terminals from IAH coastward. We'll continue to monitor rain and storm chances today. Most of this activity will remain isolated to scattered, though confidence in occurrence, timing, and coverage is low. Therefore, will continue with a PROB30, mostly from KCXO coastward. Based on the latest guidance, the best chance for rain/storms will be in the 18-23Z window. Erratic winds and reduced visibility can be expected with any strong storms. Light and variable winds return tonight under mostly clear skies. Patchy fog as well as patches of MVFR cigs will be possible toward sunrise (early Saturday) near the KCLL terminal.
