KEY MESSAGES

Updated at 1100 PM CDT Sat Aug 8 2026

- Hot temperatures are expected this weekend into next week with a Heat Advisory for portions of eastern Oklahoma, northwest and west-central Arkansas Sunday. Additional heat headlines are likely in the coming days.

- Dry weather is expected Sunday through at least the middle of the upcoming week.

- Low rain and storm chances return across the far north near the Kansas and Missouri borders late in the week.

SHORT TERM

(Through Sunday) Issued at 1100 PM CDT Sat Aug 8 2026

A ridge of high pressure aloft will continue to dominate the weather across the region for the time being. Observational trends from this afternoon suggest that dewpoints are not mixing out quite as low as the model blend would suggest in some areas. Used a blend that brought the values closer to the 75th %ile of the spread. Forecast highs Sunday should be pretty close to the readings today. Forecast heat indices warrant expanding the going Heat Advisory some, encompassing most of eastern OK and west- central AR as well as a portion of far northwest Arkansas. A few locals could briefly touch 110+ warning levels. An expanding lee trough over the High Plains to our northwest will bring an increased south wind today with some gusts. This could aid in lowering dewpoints by mixing.

LONG TERM

(Sunday Night through Saturday) Issued at 1100 PM CDT Sat Aug 8 2026

The ridge aloft will continue to maintain hot and dry weather through at least the middle of the upcoming week. Triple digit or near triple digit heat will continue daily, and more headlines are likely. The ridge weakens a bit late in the week and a boundary will approach. The latest model blend forecast has some low PoPs near the KS and MO borders. The ensemble means suggest that the best rain/storm chances would be Thursday night through Friday night. The heat may dial back a bit as well. If we do not get rain late week, models/ensembles rebuild the ridge over the south- central CONUS next weekend into the following week. A return to hot and dry weather is looking probable.
