Forecast Summary

August 2026 Temp/Precip Stats

Hot weather continues Tuesday with a Heat Advisory in effect for portions of northeast Oklahoma and west central Arkansas. Afternoon heat index values will reach up to 108 in the advisory area.

Another heat advisory has been posted for portions of eastern Oklahoma and also in the Arkansas River Valley areas, running from noon to 8 pm on Wednesday. Expect heat index values as high as 108 during the afternoon.

A localized fire weather threat will exist both Tuesday and Wednesday, focused across portions of far southeast Oklahoma. Drought-stricken fuels are increasingly receptive to fire spread and increasing winds due to the remnants of Eduoard will lead to the heightened concerns. Heed existing burn bans in this area and notify authorities immediately of any accidental fire starts or if smoke is visible.

Dangerous heat continues through the first week of September, and possibly longer. Heat stress will likely impact daytime outdoor activities. Drink plenty of water and take breaks in shade when spending time outdoors.

An extended period of hot and dry weather is likely to persist through at least the first part of September. The ongoing drought situation will worsen.

August 2026 will go down as one of the hottest on record. In fact, it was the hottest August on record at Fayetteville's Drake Field! It was the 5th hottest August at Tulsa International Airport and the 3rd hottest August at Ft. Smith Regional Airport. It was also a very dry month, with well below average precipitation observed at the 3 sites.
