KEY MESSAGES

Updated at 615 AM CDT Mon Aug 24 2026

- Temperatures mostly above normal with continued periods of locally high heat stress to continue through the week. The possible exception being around active thunderstorm activity.

- Limited risk of severe weather Sunday night into early Monday with damaging wind potential the primary hazard.

- Areas of localized fire weather concerns will persist until widespread beneficial rainfall occurs.

SHORT TERM

(Through Monday) Issued at 1145 PM CDT Sun Aug 23 2026

The immediate near term concern is the likelihood of at least scattered shower and thunderstorm development after midnight, beginning initially across parts of northeast Oklahoma and eventually working south and eastward toward daybreak, all in response to an increasing low level jet. There have already been signs of the initial development late this evening on KINX, along with other echoes across northwest Arkansas that have bubbled much of the evening. The expectation is for the potential for severe weather, focused on a locally damaging wind threat, to be highest in far northeast Oklahoma into northwest and west central Arkansas. Locally heavy rain should be expected as well. The overall trend into the daylight hours should be for an eastward shift through mid to late morning, a notable lull early afternoon, with a low chance of additional development in southeast Oklahoma mid to late afternoon in association with another mid level speed max.

In addition to the shower and thunderstorm potential through the day, a portion of the area will continue to battle heat stress concerns. A Heat Advisory will be issued for a part of east central and southeast Oklahoma roughly along and south of I-40 and along and west of the Indian Nations Turnpike. This area is less likely to have significant rainfall and convective debris during the day and therefore, continued triple digit temperatures. It is possible that if lesser thunderstorm development materializes tonight and into the morning that this advisory will need to be expanded northeastward on later shifts.

LONG TERM

(Monday Night through Sunday) Issued at 1145 PM CDT Sun Aug 23 2026

Isolated showers and thunderstorms may be ongoing Monday evening, with a gradual decrease in the potential for further development for much of the night, continuing into the day Tuesday. Overall, warmer conditions areawide are expected Tuesday, with additional heat headlines likely. The brief largely dry period for much of Monday night and into Tuesday looks to end Tuesday night as a fairly potent mid level disturbance moves into the area, leading to the development of a thunderstorm complex that moves southward into parts of northeast Oklahoma and northwest Arkansas. Cooler low level temperatures look to move southward into the area on the heels of this disturbance for Wednesday, with roughly the northern half of the area seeing temperatures closer to normal. The more normal temperatures should hang around into Thursday as well.

A change in the overall upper level pattern is expected by the weekend, with the high pressure center shifting eastward. This should bring a longer stretch of dry weather and a return to hot temperatures areawide, particularly by Sunday and next Monday.

AVIATION

(12Z TAFS) Issued at 615 AM CDT Mon Aug 24 2026

Ongoing scattered showers and thunderstorms will diminish by late morning. VFR conditions will prevail outside of any storms. Isolated storms may redevelop late this afternoon or evening, but the chances are too low to include in the TAF's at this time.
