A dangerous stretch of triple-digit temperatures is gripping eastern Oklahoma, with heat index values in Tulsa expected to reach up to 107°F by Tuesday, July 22. The National Weather Service (NWS) has issued an Extreme Heat Warning in effect through 8 p.m. Monday, with oppressive conditions expected to continue through Sunday.
Heat Danger Peaks Tuesday–Thursday
The actual temperature in Tulsa will hover near 98°F Tuesday, but it will feel much hotter due to high humidity and blazing sun. The heat index — a measure of what the temperature feels like to the human body — will climb into the 105–107°F range through at least Thursday.
Key Risks Include:
- Heat exhaustion or heatstroke
- Pavement damage and tire blowouts, especially on I-44 and U.S. 75
- Increased fire risk due to dry air and 20 mph south winds
- Danger for outdoor workers, pets, and vulnerable residents without cooling
No Relief at Night
Overnight lows will stay in the mid to upper 70s, offering little relief for homes without adequate air conditioning. The unrelenting heat makes nighttime hours especially risky for the elderly and those living alone.
