Oklahoma has seen the third-most issued heat advisories in the last 10 summers, the National Weather Service said, so we're no stranger to excessive temperatures.
Last summer, Oklahoma recorded its highest-ever heat index measurement when a Pauls Valley Mesonet site recorded a 126-degree Fahrenheit heat index on July 13.
Oklahoma is in the perfect spot in the United States for what's known as a "heat dome", a flaming hot air mass that develops when high pressure aloft prevents warm air from rising.
These heat domes can settle over Oklahoma for long periods, leading to long-lasting heat waves.
A Heat Advisory is called when dangerous heat is expected within 24 hours.
