Tulsa, Oklahoma – A heat advisory remains in effect for much of eastern Oklahoma and west-central Arkansas through 8 p.m. Wednesday, with heat index values soaring as high as 109°F in the advisory area. Residents should prepare for dangerous heat conditions, take frequent breaks in air conditioning, and stay hydrated.
According to the National Weather Service Tulsa, storm chances will stay low during most of Wednesday but return late tonight into Thursday, primarily impacting northeast Oklahoma as a cold front moves in from Kansas. The main threats include cloud-to-ground lightning, heavy downpours, and brief gusty winds, especially for communities north of Tulsa, Bartlesville, and Miami. Thunderstorm probabilities remain at 20–30% in these areas from 1 a.m. to 1 p.m. Thursday, dropping to less than 10% elsewhere.
Travelers and outdoor workers should monitor local forecasts closely, seek shelter indoors during thunderstorms, and avoid flooded roadways. Those susceptible to heat illness should check in with family or neighbors, and ensure pets have access to cool water and shade.
This marks the second significant heat wave of July and echoes similar high-heat patterns from 2023. More advisories or updates could follow if conditions intensify.
