Tulsa, Oklahoma – Dangerous heat is tightening its grip across eastern Oklahoma and northwest Arkansas, with heat index values climbing well above 100 degrees each afternoon through Tuesday. The hottest conditions are expected Tuesday, when the combination of heat and humidity could push “feels like” temperatures as high as 110 degrees, increasing the risk of heat-related illness for anyone spending time outdoors.
According to the National Weather Service in Tulsa, widespread heat index values between 100 and 110 degrees are expected through Tuesday, with Tuesday forecast to be the hottest day of the stretch before slightly lower heat indices arrive during the second half of next week.
Tulsa is expected to reach a maximum heat index of 106 degrees Sunday, 107 Monday, and 109 Tuesday before easing to 103 Wednesday and Thursday. Elsewhere, Fort Smith could reach 107 degrees Monday and Tuesday, while Muskogee and McAlester are forecast to peak near 109 degrees Tuesday. Ozark, Arkansas, could see one of the highest readings in the region, with a 111-degree heat index Tuesday, while Rogers is forecast to reach 103 degrees Tuesday.
The prolonged heat will create hazardous conditions for outdoor workers, athletes, and anyone without access to adequate cooling. Residents should drink plenty of water, wear lightweight clothing, limit strenuous activity during the hottest part of the afternoon, and take frequent breaks in air-conditioned buildings or shaded areas. Never leave children or pets inside parked vehicles, even for a short time.
The dangerous heat will also increase electricity demand as air conditioners run continuously across the region. Residents are encouraged to check on elderly neighbors and those without reliable cooling.
Additional heat advisories or excessive heat warnings could be issued if forecast temperatures continue to rise. The most dangerous conditions are expected during the afternoon and early evening through Tuesday, with gradual improvement possible later in the week.
