KEY MESSAGES

Updated at 1111 PM CDT Fri Aug 7 2026

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

- Rain and storm chances will trend lower and shift south tonight into Saturday, ending by Saturday evening.

- Dry weather is expected Sunday into at least the first half of next week.

SHORT TERM

(Through Saturday) Issued at 1111 PM CDT Fri Aug 7 2026

A large area of high pressure aloft is centered over the Southwest. An upper trough axis exists on the eastern side of the ridge from the MO Ozarks down to the ArkLaTex. Shower and storm activity that has been occurring along and east of the trough axis will shift gradually south and east with time in tandem with the feature. Some low storm chances will linger into Saturday over portions of west-central AR and southeast OK, but by and large most of the area will be dry this weekend.

The model blend (NBM) forecast highs looked reasonable based on what happened today and do not stick out in the guidance spread, staying close to the median. Forecast heat indices warrant a heat advisory over much of eastern OK and the lower Ark River Valley of west-central Arkansas. Made some minor tweaks to the going headline, otherwise it will continue intact.

LONG TERM

(Saturday Night through Friday) Issued at 1111 PM CDT Fri Aug 7 2026

Some subtle height rises occur over the region as the ridge over the Southwest expands some. Our area will be under its influence on its eastern side into early next week. Expect a multi-day stretch of hot (triple digit heat eastern OK) and dry weather. Heat headlines are likely to continue daily during this time. It is not unusual for it to be hot this time of year. The period from mid-July to mid-August is the hottest period of the year climatologically.

Rain/storm chances increase some for the latter half of the week as the ridge over the Southwest goes away and reforms over the Gulf Coast/Southeast. A weak boundary may try to push into the region from the north/northeast and focus activity. Forecast highs also trend relatively cooler during this time as well.
