KEY MESSAGES

Updated at 612 PM CDT Sun Aug 30 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 1147 AM CDT Sun Aug 30 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. Otherwise, generally 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 slightly warmer than last night, and mainly in the 70s except possibly in the typically cool spots.

LONG TERM

(Tomorrow through Sunday) Issued at 1147 AM CDT Sun Aug 30 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 on the lower side through Tuesday (though perhaps slowly rising with time), so even though temperatures will be hot, heat indices will only run slightly higher than the temperatures. This may keep heat products confined to the typically hotter locations. This is already the case for Monday, with a pair of Heat Advisories for portions of Northeast OK and west-central AR.

By mid week the low level flow will become more S-SSE instead of S- SSW which will help low level moisture creep upwards. The increase in dew points may expand the footprint of heat products at that time. The chance for rain was already pathetic, and it looks even lower now for the mid week, with only a 5-10 percent chance of a few higher terrain diurnal showers. Models increase the chance of similar showers or storms to 10-20% over the higher terrain of northwest AR next weekend with the upper level high sitting just west of the area. With continued hot, dry, and breezy weather, some fire weather potential will exist each afternoon throughout the region.
