KEY MESSAGES

Updated at 1232 PM CDT Sat May 30 2026

- Storm chances along with some threat for severe storms will persist across northeast Oklahoma and northwest Arkansas through tonight.

- Rain chances decrease and temperatures warm Sunday into the first part of next week. Afternoon heat index values may reach triple digits in a few spots.

SHORT TERM

(Through tonight ) Issued at 1139 AM CDT Sat May 30 2026

Scattered showers and thunderstorms are expected to develop across parts of northwest Arkansas later this afternoon into early evening, and these storms will pose a limited severe weather threat. These storms are expected to dissipate this evening with the loss of heating. Additional storms are expected to form across parts of Kansas into north central and possibly central Oklahoma by late afternoon. These storms may move into northeast Oklahoma this evening and will also pose a limited severe weather threat. These storms will likely decrease in intensity by late evening, but a few showers and storms may linger into the overnight hours across parts of northeast Oklahoma and northwest Arkansas.

LONG TERM

(Tomorrow through Saturday) Issued at 1139 AM CDT Sat May 30 2026

An upper ridge will build over the southern plains Sunday into early next week, bringing hot and humid conditions. Afternoon heat index values may reach or exceed 100 degrees in a few spots Sunday and Monday. Mainly dry weather is expected during this time frame with the upper ridge in place.

A backdoor cool front will move across the area Tuesday, with a drier and slightly cooler airmass moving into the area for the middle part of the week. Shower and storm chances will remain limited as the upper ridge maintains its hold over the area.

Late this week into next weekend, the upper ridge breaks down and an upper level storm system begins to approach from the west. This will increase shower and storm chances Friday and Saturday and also return a more humid airmass to the area. Temperatures will remain near the seasonal averages from Wednesday into next weekend.

AVIATION

(18Z TAFS) Issued at 1232 PM CDT Sat May 30 2026

Outside of direct impacts from thunderstorms, VFR conditions are likely to prevail for all sites through the forecast period. Showers and thunderstorms are forecast to develop by mid to late afternoon across NW AR and far NE OK, and PROB30 groups were maintained for AR sites as a result. Late this evening and into the overnight period, additional showers and storms may move east from central Oklahoma and impact KBVO, KTUL, and KRVS. Confidence remains low in this scenario as convection should be weakening at this time, but potential was high enough to maintain PROB30s for these sites. There is a low chance of a shower or storm in the vicinity of KMLC as well, but low probability precludes mention in the TAF at this time. Breezy south winds become light overnight before increasing again late Sunday morning.
