Issued at 1120 PM CDT Tue Aug 11 2026

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/
