Tulsa, Oklahoma – Dangerous heat returns to eastern Oklahoma and parts of west central Arkansas Saturday, with heat index values soaring as high as 109°F and high temperatures in the lower to mid-90s. Outdoor workers, residents without reliable air conditioning, and anyone planning time outside are at increased risk for heat stress and illness during the advisory period.
According to the National Weather Service Tulsa, a Heat Advisory is in effect from noon to 8 p.m. Saturday, July 26. The warning covers Tulsa, Bartlesville, McAlester, and extends into portions of west central Arkansas, including areas near Fort Smith and Hugo. Officials urge people to seek shade, take frequent A/C breaks, and check on neighbors—especially the elderly and those without cooling options.
Travelers on US-75, I-40, and I-44 may face elevated roadside risks, while outdoor events in Tulsa, Muskogee, and Miami should plan for extra cooling stations and hydration options. Local power grids may see increased demand for air conditioning, so residents are asked to conserve energy when possible. The region has already endured several days of excessive heat, and similar advisories could be issued into Sunday if the pattern persists.
The National Weather Service urges everyone to stay hydrated, limit strenuous activity, and watch for signs of heat-related illness. Additional updates are expected if conditions worsen or the advisory extends beyond Saturday evening.
