KEY MESSAGES

Updated at 627 PM CDT Mon Aug 31 2026

- An extended period of hot and dry weather will persist through the next week. Heat headlines are expected at times.

- Rain chances look very low through the forecast period.

- The ongoing drought situation will continue to worsen. Localized fire weather concerns will develop each day.

SHORT TERM

(Through tonight ) Issued at 1136 AM CDT Mon Aug 31 2026

Hot conditions will continue through the afternoon and evening across the entire forecast area. Afternoon highs will again reach the upper 90s to low 100s. Due to ongoing drought conditions, dew points will remain depressed, mostly in the low to mid 60s. Afternoon heat indices will reach 105-107 F within the Heat Advisory across northeast OK and west-central AR. Otherwise, mostly clear skies and breezy southerly winds will persist.

Tonight will be mild and quiet with light southerly wind and mostly clear conditions. Low temperatures will be similar to last night, and mainly in the 70s.

LONG TERM

(Tomorrow through Monday) Issued at 1136 AM CDT Mon Aug 31 2026

The pattern will remain stagnant over the next week with a sprawling and strong upper level high either overhead or nearby. Temperatures will remain consistent, with highs in the upper 90s to low 100s each day and lows mostly in the 70s. Dew points will remain in the low to mid 60s through Tuesday, so even though temperatures will be hot, heat indices will only run slightly higher than the temperatures. This will continue to keep heat products confined to the typically hotter locations. For Tuesday, the Heat Advisory will span the lower elevations of northeast OK and west-central AR.

By Wednesday and onwards, the low level flow will become more southeasterly and strengthen slightly as a weak decaying tropical system moves into Texas, which will help low level moisture creep upwards. The chance for rain is essentially zero through the work week for most locations. The one exception will be parts of southeast OK on Thursday, as the remnants of the tropical system graze southeast OK, bringing a 10-15% chance of a few showers.

A similar 5-10% chance of diurnal showers is possible for the higher terrain of northwest AR next weekend as the upper level flow becomes northwesterly. In any case, meaningful precipitation remains extremely unlikely for now. With continued hot, dry, and breezy weather, some fire weather potential will exist each afternoon throughout the region.
