Tulsa, Oklahoma – Sweltering conditions are putting eastern Oklahoma and northwest Arkansas at risk, as heat index values soar above 110°F Tuesday afternoon, prompting urgent heat advisories and an extreme heat warning for Franklin County.
According to the National Weather Service in Tulsa, a Heat Advisory remains in effect for much of eastern Oklahoma and northwest Arkansas from noon to 8 p.m. Tuesday, July 22.

Officials urge residents to watch for heat exhaustion, wear loose and light clothing, and take frequent water breaks—especially for those working outdoors or without air conditioning.
In Tulsa, Fort Smith, Fayetteville, and surrounding communities, high humidity combined with upper-90s temperatures will drive heat stress impacts into early next week.
