Issued at 101 AM CDT Sat Aug 15 2026- An Extreme Heat Warning remains in effect across the entire Mid-South through Sunday evening.
- Overnight lows will remain unseasonably warm, preventing recovery and creating stress for at-risk populations.
- Heat headlines will likely be needed into next week as upper ridging remains over much of the area and hot and humid conditions continue.
