A ridge of high pressure in the middle and upper atmosphere developed over the south central United States during mid August. Unseasonably hot afternoon temperatures reaching the mid 90s to near 100 degrees, combined with unseasonably high humidity, resulted in heat index values in the 110 to 120 degree range across much of eastern Oklahoma on the 11th through the 13th. At least eleven people were treated for heat-related issues in Tulsa, four of which were transported to the hospital.
