KEY MESSAGES

Updated at 1053 PM CDT Sun Sep 13 2026

- Unseasonably hot temperatures continue through the upcoming work week. Expect heat headlines on multiple days.

- While much of the region has received rainfall over the past few days, the ongoing drought conditions will require much more rainfall for improvement. Fire weather concerns will continue during periods of stronger winds.

SHORT TERM

(Through Monday) Issued at 1053 PM CDT Sun Sep 13 2026

Diffuse surface boundary over the region should remain quiet overnight as it lifts back north of the local area. Expanding hot airmass will result in triple-digit heat indices over a broader area Monday afternoon with much of west central AR and large portion of eastern OK at least close to 105. Current configuration of heat advisory for today still looks valid, though marginal in some areas. With upper ridge axis just to our east, isolated afternoon convection remains possible especially over the higher terrain of western AR.

LONG TERM

(Monday Night through Sunday) Issued at 1053 PM CDT Sun Sep 13 2026

The upper level pattern is not expected to change much this week with ridge centered to our east and westerlies remaining to the north, resulting in several more days of summer weather. Surface boundary lingering across the Central Plains remains just close enough that some associated convection could brush northern areas a time or two, along with above mentioned possibility of isolated, mainly terrain-deriven convection each afternoon. But the main message will be well above normal temperatures and likely need for additional heat headlines.

Considerable uncertainty remains as to just when this pattern may finally break down and allow for a frontal passage. Extended forecast continues to reflect a cooling trend with more meaningful rain chances early next week, but spread in guidance remains considerable in that range.

AVIATION

(06Z TAFS) Issued at 1218 AM CDT Mon Sep 14 2026

VFR conditions are expected through the period with just some scattered mid and high clouds through the day Monday. Southerly winds will pick up and become gusty by mid to late morning. Gusts around 20 knots will be common during the day before backing off some after sunset.
