KEY MESSAGES

Issued at 1146 PM CDT Thu Aug 13 2026

- The ongoing heat wave to persist through the weekend with near triple-digit high temperatures.

- Rain chances will remain virtually non-existent under this very stagnant pattern as convection is deflected around the ridge.

- Worsening drought conditions to continue through this increasingly hot and dry regime.

DISCUSSION

Issued at 1140 PM CDT Thu Aug 13 2026

An upper-level ridge centered across the north-central gulf coast will continue to migrate northwest, becoming centered over the ArkLaTex by Friday evening, remaining anchored across the ArkLaTex into the Southern Plains through the remainder of the forecast period. The result will be a continuation of hot temperatures nearing or slightly exceeding 100 degrees each day through the middle of next week. A Heat Advisory remains in effect for the entire ArkLaTex through the weekend as heat index values are forecast to exceed 105 degrees. Additionally, this stagnant hot and dry pattern will result in worsening drought conditions.

At the surface, a nearly stationary high across the gulf will continue to bring southerly winds to the region. The stronger daytime winds, up to 10 mph with higher gusts, can be expected across east and northeast Texas as well as southeast Oklahoma. The combination of dry conditions and the increased winds will lead to the possibility of wildfires across these areas through the weekend.

Otherwise, models continue to suggest a few afternoon showers and thunderstorms possible on Tuesday afternoon as a weak surface boundary drifts south across the region. /05/

AVIATION

Cu field today thinned out mid to late afternoon with little change in the current pattern over the next several afternoons. The SFC winds will keep near 5-10KT in the evenings and most of the overnights, then resuming SW 5-15KT early in the day. We will back to due S by mid afternoon with the sea breeze arriving, but little if any rainfall is expected under this subsident heat ridge overhead which is building strength. /24/
