.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/
