KEY MESSAGES

Updated at 1214 AM CDT Tue Aug 11 2026

- Oppressively hot and dry weather will persist through the workweek. A Heat Advisory remains in effect for much of E OK and W AR on Tuesday. Additional heat headlines are likely throughout the remainder of the week and into this weekend.

- Rain chances are unlikely through the forecast period.

SHORT TERM

(Through Tuesday) Issued at 1117 PM CDT Mon Aug 10 2026

Tuesday will be another rinse and repeat day of dangerous heat across the region. The upper-level ridge will hold strong overhead through the middle part of the week, with very little relief from the afternoon heat. Overall, temperatures and humidity on Tuesday will be very similar to what occurred on Monday. Afternoon highs will climb into the upper 90s and lower 100s. Some mixing may occur as low-level southerly wind speeds increase late in the afternoon. This may help reduce/cool off apparent temperatures some. Nevertheless, a Heat Advisory remains in place across most of the forecast area, with the exception of the terrain areas of northwest AR, Tuesday from noon until 8 PM.

LONG TERM

(Tuesday Night through Monday) Issued at 1117 PM CDT Mon Aug 10 2026

A mid/upper level synoptic trough will amplify along the West Coast Tuesday into Wednesday. As the trough deepens and nudges inland, the summer ridge and its axis will shift eastward, becoming positioned over the northern Gulf coast by Thursday. Longer range models are suggesting the ridge will eventually retrograde back over the Southern Plains late in the weekend and into early next week. Unfortunately, the result of all this will not really change the overall local weather pattern...it will still be consistently hot and mostly dry through the remainder of the workweek, with daily afternoon high temperatures reaching the upper 90s and lower 100s and overnight temperatures generally in the upper 70s and lower 80s. Heat headlines will likely be needed for at least a portion of the forecast area each afternoon for the foreseeable future. Please continue to take precautions to stay cool and hydrated when outdoors this week.

As the upper-level ridge becomes stationed over the southeast CONUS late this week, latest suite of global models and ensembles show a weak frontal boundary pushing into and stalling across central KS Thursday night. Consensus in the models keep the frontal boundary well north of the area through the weekend. This is in contrast to previous model runs, where they showed the front stalling closer to the KS/OK border through the upcoming weekend, producing low shower and thunderstorm chances for parts of far northeast OK and far northwest AR. With models now stalling the front farther north, rain chances seem unlikely through the forecast period at this time.
