KEY MESSAGES

- An elevated threat for dangerous heat stress will continue through the weekend into next week. A Heat Advisory remains in effect, and an Extreme Heat Warning may be needed for some portions of the area by early next week.

- Rain chances remain minimal through the weekend, with some isolated chances into next week.

DISCUSSION

Issued at 223 PM CDT Thu Aug 13 2026

Through next Thursday...

Dangerous heat will remain the primary focus through the period. The strong subtropical ridge (597-598DM) will persist across the region through the weekend into early next week. This will lead to increasingly warm thermal profiles and strong subsidence across the Gulf Coast region. Rain chances will remain squashed and shunted to the east-southeast through the weekend, with only limited coverage. The humidity may drop a touch into Friday, but overall messaging of dangerous heat remains the same. No changes have been made to the inherited heat HWO graphic and subsequent heat advisory through the weekend. Stay cool and hydrated and check on vulnerable populations.

Some of the hottest days of the summer are expected, with highs peaking into the low 100s especially Sunday through Tuesday. Thermal profile climatology (22C to 25C at 850mb) indicate potential analogs into the low 100s (101F to 103F and median around 102F), with some higher values exceeding that. Regardless, dangerously hot conditions will continue, even if we mix a little more efficiently at times. Some portion of the area may need to be upgraded to a "Significant" risk and subsequent Extreme Heat Warning, but this focus looks far enough out in time to hold off just yet. The ongoing heat headlines continue through the overnight periods with limited relief at night.

Rain and storm chances remain limited through the period, with only peripheral areas seeing scarce showers and storm coverage, mainly into early next week. Some relaxation of the stout ridge will occur into early next week. In conjunction with increased deeper moisture, increased convergence from frontal zone sagging southward may cause some better rain coverage into early to mid next week. Otherwise, dry conditions will persist most areas through the weekend. /DC/
