Tulsa, Oklahoma – A dangerous stretch of heat is gripping eastern Oklahoma and parts of northwest Arkansas this weekend, with heat index values climbing as high as 107°F in some cities through early next week.
According to the National Weather Service in Tulsa, this is the first major heat wave of the season, and it brings an elevated risk of heat exhaustion and heat stroke, especially in areas like Tulsa, Fort Smith, and Fayetteville. Temperatures will range from the low to mid-90s, but the combination of heat and humidity will make it feel significantly hotter.
Heat alerts extend across counties including Washington, Sequoyah, and Muskogee, where maximum daily heat indices between 100°F and 107°F are forecast through at least Monday. Residents are urged to stay hydrated, wear light-colored clothing, and take frequent breaks in shaded or air-conditioned spaces. Outdoor workers and vulnerable populations face the highest risks.
Symptoms like dizziness, nausea, and confusion may signal the onset of heat-related illness. Emergency services recommend calling 911 if someone becomes unconscious or shows signs of heat stroke.
High heat is expected to persist through early next week. Additional advisories may be issued as conditions evolve.
