.DISCUSSION...
Issued at 1120 PM CDT Tue Aug 11 2026

Overall synoptic pattern will remain fairly stagnant through  at
least midweek next week. An upper-level ridge centered across the
north-eastern gulf will gradually build northwest, becoming
centered across the ArkLaTex by Friday evening. This upper-ridge
will remain anchored across the region through weekend into early
next week. Subsidence associated with the ridge will drive daytime
temperatures into the upper 90s through the end of the workweek,
and into the triple digits across many locations during the
weekend into next week. With increased low-level moisture across
the region, afternoon heat index values will range from 105 to 110
degrees each afternoon through Friday. Thus, a Heat Advisory
remains in place across the entirety of the ArkLaTex through
Friday with extensions expected thereafter.

A surface high across the Gulf of America will continue to
maintain southwest winds across the region trough the forecast
period. The combination of the heat, lower afternoon relative
humidity values due to atmospheric mixing, and wind speed values
near 10 mph will increase the wildfire threat across the region.

Otherwise, rain chances will be very limited each day as surface
and upper-level high pressure prevail across the region. /05/
