KEY MESSAGES

Issued at 1146 PM CDT Wed Aug 12 2026

- A prolonged heat wave shows no signs of relenting anytime soon.

- Rain chances will remain non-existent under this very stagnant pattern.

- Flash drought conditions possible in this increasingly hot and dry regime.

DISCUSSION

Issued at 1144 PM CDT Wed Aug 12 2026

An upper-ridge across the northern gulf will continue building across the ArkLaTex through the weekend. Subsidence associated with the upper-ridge will maintain typical August heat with afternoon highs nearing the triple digit mark each day through the middle of next week. The combination of hot temperatures and a persistent fetch of gulf moisture will allow for afternoon heat index values to range from 105 to 110 degrees each afternoon prompting a Heat Advisory that is now in effect areawide through the weekend.

Rainfall will be mostly non-existent through the forecast period. The only exception to this could be a few showers and thunderstorms possible on Monday and Tuesday afternoon across portions of north Louisiana as a weak disturbance translates westward along the southern periphery of the ridge. However, coverage will remain isolated.

Otherwise, with daytime wind speed values up to 10 mph through the remainder of the work week, steady drying could lead to worsening drought conditions and an ever increasing wildfire threat. /05/
