What happened

The episode as NWS TSA wrote it up.

During the middle of July strong high pressure in the upper atmosphere became anchored over the south central part of the United States. This high pressure brought extreme heat to parts of northeast Oklahoma. At the Tulsa International Airport eight days out of eleven from July 16 to July 26 had high temperatures above 100. Meanwhile, on six of those days the low temperature did not fall below 80. Humidity was also a problem with dew points generally in the lower to mid 70s. This resulted in afternoon heat indexes around 115. Over the time period several people were treated for heat related illnesses. One man in rural Pawnee county died from heat stroke on July 17.
