Tulsa, Oklahoma – Extreme heat is set to grip eastern Oklahoma, with heat indices soaring above 105°F across Tulsa, Fort Smith, and Fayetteville by this weekend and early next week, raising urgent concerns about heat stress and public safety.
According to the National Weather Service in Tulsa, rain chances briefly rise to 30–50% on Thursday for areas including Bartlesville and Miami, but drop to 10% or less across the region by Friday and remain low into next week. This shift comes as the region prepares for relentless heat, with Tulsa and Fort Smith projected to reach heat indices of 105°F from Sunday through Tuesday.
Residents in McAlester, Muskogee, and Hugo will also see dangerous heat, with daily maximums ranging from 101–105°F. Scattered thunderstorms are possible through the end of the week, bringing risks of cloud-to-ground lightning, locally heavy rainfall, and gusty winds, especially along major highways like I-44 and US-412.
Oklahomans are urged to monitor forecasts, seek indoor shelter during storms, and follow heat safety precautions: stay hydrated, limit outdoor activity, and check on vulnerable neighbors. Heat-related illnesses can develop quickly in these conditions.
The threat of high heat stress will likely persist into next week, with more advisories possible as temperatures remain well above seasonal averages.
